Active Audio Processor Increases your dynamic rangeDynamic range is to music what pe rspective is to painting or photography. It givesaudio depth and feeling. Some of the dynamic range in most music is lost in therecording or broadcast process, but the expansion ci rc uit in the AD-1706 canrestore up to 8 dB of this loss. You'll discover your music has even more realism,better definition and lower background noise while maintaining full response andultralow distortion — even at high volume levels. The superb noise reductioncircuitry sifts out up to 10 dB of noise from records and hiss from tapes, toeffectively increase your system's total dynamic range by up to 18 dB.

Troubleshooting redefined: Heathkd's new IT-2232 Component Tracer is an idealaddition to anyone's workbench for troubleshooting electronic ci rcuits. It enablesa user to check digital and analogcircuits that have no power applied to them. Thetracer does this by displayinga component's or circuit's unique E71 characteristiccurve on its CRT. And, with its two input channels and dual display, the tracer canbe used to compare suspect circuits or devices against a known good unit.Unique display: The IT-2232 features two separate inputs that can be viewed asindividual traces on its 3-inch CRT or together in a unique superimposed displayOn the scaled screen, one channel is seen as a solid line trace while the second isconverted by a unique, patent-pending circuit into a dotted line. In the superim-posed mode, good and suspect units are checked at the same time and theiroverlapping traces compared. Any differences between the two are then clearlyidentified to effectively determine good or bad components.Multi-purpose tester: The Component Tracer is an extremely helpful troubleshoot-ing tool and an ideal addition to anyone's service bench. It can test circuit boardsand components without powering up the circuit under test. Also, it can accu-rately check semiconductor devices in circuit as well as out of circuit. Using thecolor-coded test probes that are included with the tracer, even the most inex-perienced user can check for shorts, opens, or wrong pa rts in a minimum amountof time. In addition, the tracer can be used to detect pa rts that cause difficult-to-locate problems due to noise leakage, temperature instability and intermittentconditions that might go undetected using other testing methods.Dual testing ranges: Two ranges, 5 and 50 volts, are provided for low and high

voltage capacity devices. Current limiting protects all circuits and components.Kit IT-2232, Component Tracer, Shpg. wt. 15 lbs. 249.95

10-4360 60 MHz Triple Trace Oscilloscope and optional 10A-4200 Time-Voltage ModuleCompare the 'all in one probe' measurement capability ofHeath's new top-of-the-line scope and companion voltage-frequency module with the competition, and see our value.Yes, you can pay more for a 60 MHz scope somewhere else,but you won't buy any more features. versatility or money-saving sell-servicability than is found in th e 10-4360.

Multi-bate oscilloscope: Two of the 10-4360's channels are controlled by anattenuator network of 12 calibrated ranges from 2 millivolts/cm to 10 volts/cm.This provides you with the needed sensitivity to make low signal measurementswithin an accuracy of 3% using AC or DC coupling. The 10-4360's third t race.available at the external input. can bevievred bysimply pressing the TRIPLE tracebutton. For added versatility. Channel 2's input signal can be inverted and-added" to Channel l's signai for making differential measurements.Extra wide DC to 60 MHz bandwidth: The 10-4360 provides you with the band-width needed to view waveforms in both digital and analog circuits. Even thoughthis multi-trace scope has a specified bandwidth of 60 MHz. signals up to andbeyond 90 MHz can be displayed on its 8 x 10 cm screen.Sweep control: Besides providing the sweep speeds to observe fast logic pulses,the 104360 also supplies a delayed sweep for fast and accurate timing measure-ments. Internal vertical delay lines ensure that the horizontal sweep starts at thebeginning of the input signal. This permits you to view a complete vertical wave-form. With its very fast 7 ns rise time, rapid rise-time signals are faithfully re-produced. Also providing sweep control is the calibrated time base. It ranges from0.1 second/cm to 100 ns/cm in a 1-2.5 stepped sequence. And, any sweep speedcan be expanded 10 times by simply pulling a switch. A delayed sweep allowsyou to see the leading edge of a waveform as well as select the exact portionof a waveform for expansion by any factor you desire.Complete trigger system: The oscilloscope can be triggered from either one of thevertical input channels, My voltage, or from an external trigger which is also theinput for the third trace. A filter network allows you to choose the AC. DC. low orhigh frequency component of a signal to be used for triggering the scope. Thisfilter network also allows you to reject either the horizontal or vertical sync pulsesof TV signals when using them for triggering on video waveforms. Fine triggeradjusting is done with a precise level cont rol. When a trigger signal isn't used, thebaseline can be automatically displayed by using the scope's automatic mode.Kit 104360, Shpg.

Di Powerful Winchester disk drive data storageHuge on-line storage capacity: With an 11 megabyte storage capacity, Winchesterdrive conveniently stores data that would require several dozen floppy diskettes.This allows your H:Z-100 to handle very large amounts of data, such as lists ofaccounts or large inventories.Economical alternative: For serious computer users, a Winchester disk drive canbe an inexpensive data storage substitute for a 5.25-inch floppy disk drive insome situations. Especially when many disk drives, costing mo re than a Winches-ter drive, are required to put all information "on-line" at the same time.High-speed ac cess: Dramatically decreasing seek time over floppy disk dr ives, aWinchester drive can be finished retrieving information while a 5.25-inch disksystem is Just getting started. The H2-l00's Winchester disk drive can accessinformation ten to twenty times faster than a 5.25-inch floppy disk system.Increased data-handling efficiency: Coupled with high-speed access, an in-creased data packing technique allows the winchester to transfer data at fivemegabytes per second. With an internal Winchester drive, this extremely hightransfer rate greatly increases the H.2-100's efficiency in applications requiring agreat many disk operations.Convenient: With its huge storage capacity, the Winchester allows you to store allyour programs on its sealed disks instead of several dozen floppy diskettes.

A versatile 8-bit computer and a professionalvideo terminal built into a desktop computera

The H-89 All-In-One Computer is an outstanding single-component system that'sready to work for you. Use it to increase your office's efficiency with businessapplications and word processing. Create your own programs with versatileoperating systems and languages. And, manage your home easier with financialprograms and information services.

FEATURING A SAVINGS OF UP TO $300

• Dual 8-bit microprocessors for faster computing• • 48K byte RAM memory that expands to 64K bytes. • Internal 5.25 - disk drive stores up to 100K bytes

• High-Quality, professional typewriter keyboard• Uses both HDOS and CP/M operating systems• Easily add peripherals or increase data storage

Separate microprocessors: The H-89 uses two Z-80 microprocessors, one tovideo and keyboard functions and the other for just powerful computing. With theterminal using its own microprocessor, the computer can concentrate on high-speed processing. This allows the H-89 to be mo re versatile than other 8-bitdesktop computers and computer systems.Expandable memory: At 48 kilobytes of RAM. the H-89's memory is large enoughto run most 8-bit software. And for larger programs, memory can be increased upto 64 kilobytes. To add the extra 16 kilobytes of RAM. you simply install the wiredWH-88-16 RAM Expansion Kit (p. 37).Increased data storage: For most of your data storage needs, the H-89 comes withan internal 5.25-inch floppy disk drive (H-17-1 on page 37) and an H-88-1 hard-sectored disk controller board (p. 37). This standard equipment allows you to sto reup to 100K bytes of data on a single floppy diskette. When you need mo re storagespace, the H-89 answers with many add -on storage capacities in a number ofdifferent ways. You can increase the amount of disk storage by connecting anH-77/Z-87 external floppy disk system (p. 37) with its one or two disk drives toyour H-89. This now brings the total storage capacity up to 300K bytes (100Kbytes per drive). Storage capacity can be further increased by replacing theH-88-1 controller board with a Z-89-37 soft-sectored disk controller board(p. 37). With the Z-89-37 board installed in your H-89, total storage (withH - 77/2-87 connected to the H-89) becomes 480 kilobytes. Still more storageis gained by replacing the internal disk drive with a double-sided double-densitydisk drive (H-17-5 on page 37) and replacing the H-77/Z-87 with an H-37 externalfloppy disk system. This arrangement increases storage capacity to a massive1.92 megabytes. For more information on these and other storage capacitiesfor the H-89, see page 37.Professional keyboard: With its standard typewriter keyboard, the H-89 allowstouch-typists to immediately take advantage of word processing. Typists easilymove from their electric typewriters to the keyboard of the H-89 without losingtime in retraining. And, the rugged, highly-reliable keyboard is built to take theconstant use found in the office environment. For programmers, the keyboard candisplay the entire ASCII character set, both upper and lower case, along with 33graphic symbols. A 12-key keypad beside the keyboard allows accountants torapidly enter numbers white using bookkeeping and other spreadsheet programs.Quality video terminal; All information is shown on a 12-inch high-quality videodisplay tube (or CRT) that provides highly detailed characters. The optional whiteor green CRT displays 24 rows of 80 characters each as well as a software-controlled 25th line. The display is always bright even when the maximum 2000characters fill the screen. On the screen, upper-case characters are tonged by a5 x 7 dot matrix while lower-case characters use a 5 x 9 dot matrix.Add on the peripherals: For your convenience and the H-89's versatility three EIAstandard RS-232C serial interlace ports are pa rt of the H-89. These three stan-dard serial ports let you connect peripherals that make the H-89 more useful toyou. Connect a printer such as the H2-125, located on page 41, for printedcopies. Or, connect a modem (page 40) and use the H-89 to talk to other comput-ers or access information services with their wealth of interesting, useful andprofitable information, and services.

Most programs are available on 5.25-inch hard-sectored and 5.25-inchsoft-sectored floppy diskettes. See all th e software programs for the H/2-89All - In-One Computer on pages 54 through 58.

H-89 software: Choose from either HDOS or CP/M (both on p. 54) as your diskoperating system, or use both. Each operating system features sophisticatedsystem control and both suppo rt all HeathiZemth disk systems. Software thatcan be used with either HDOS or CP/M can be found on pages 54 through 58. Thisincludes: programming languages, financial modeling and planning software,utilities, word processing software, learning software and games. By joining HUG(p. 43) you can gain access to its library of over 700 software programs for yourH-89 which are constantly being updated.User oriented manuals: A step-by-step assembly manual shows you exactly how toassemble your own H -89 computer. Each step is clearly written and well illus-trated to ensure a properly built and working kit.

There are several different ways storagecapacity can be increased. You can use the standardinternal H-88-I hard-sectored disk controller boardof the HIZ-89 and externally add more single-sided5.25-inch floppy disk drives to your Computer. Or •replace the H-88-1 with a Z-89-37 soft-sectored diskcontroller board and use either single-sided or high-capacity double-sided 5.25-inch floppy disk drives.HS-77/Z-87: Triple the data storage of your H/Z-89with a kit H5-77 or assembled Z-87 Floppy DiskSystem. Each single-sided disk drive (model numberH-17-11 of either system is capable of storing 100Kbytes (kilobytes) on a diskette for an added 200Kbytes of storage capacity. That's a total capacity of300K bytes, counting the 100K byte capacity of theComputer's internal drive.

Different versions available: the kit HS-77 is avail-able in one and two drive versions. A kit one-drivesystem is available under model number HS-77-1and a kit two-drive system is available under modelnumber HS-77-2. The model number for an as-sembled two-drive disk storage system for the H:Z-89 is Z-87-89. An assembled two-drive system forthe Z-90 Computer is ordered by using the Z-87-90model number. Refer to the chart below for a sum-mary of these storage systems.Available separately: Besides the Floppy Disk Sys-tems themselves, each component of these systemsis available separately. See the list of disk storageaccessories listed below. Anytime you wish, you canupgrade your Computer system to handle more data.With multiple drives, you can mount operating sys-tem and program disks at the same time. All diskdrives are factory assembled and tested to make thekit versions of the disk systems faster and easier tobuild. It ensures worry-free operation.Quality designed: The H-17-I disk drive mounts ver-tically into its cabinet. Mounted this way the drivetakes up less space than units which mount theirunits horizontally. Inside the tough metal cabinet ofboth disk storage systems is a special heavy-dutypower supply It provides enough power for each sys-tem with enough extra capacity to stay cool, evenunder the heaviest use. For other quality disk storageand H2.89 and Z-90 Computer accessories, checkover both lists below.Increased drive storage: Replace the H-88-1 hard-sectored controller board in your H-89 with theZ-89-37 soft-sectored disk controller board and in-crease data storage 1.6 times. The Z-89-37 allowsthe single-sided H-17-1 disk drive to store up to160K bytes of data. Used with an H/Z-77 or Z-87Floppy Disk System, the Z-89-37 increases their ca-pacity to 320K bytes. Added to theComputer's inter-nal drive storage and you get a total of 480K bytes.Used together: Both the H-88-I and the Z-89-37controller boardscan be used in an H/Z-89or Z-90 atthe same time. This allows you to choose theamounts of data storage you wish with different disksystems. The H-88-1 controller board can only beused with a single-sided H-17-1 disk drive such asthe one that comes standard with the H;Z-89, How-ever, the Z-89-37 controller board can be used witheither the H-17-1 or H-17-5 (double-sided) drive.

H-37 Floppy Disk System: With a Z-89-37 controllerboard and the two-drive H -37 System, up to 1.28megabytes of additional data storage is provided.The high-capacity double-sided 96 TPI H-17-5 diskdrive, used in the H-37, makes this possible with itslarge 640K bytes per drive storage capability By re-placing the internal H/Z-89 single-sided drive(H-17.1) with an H-17-5 drive, a huge 1.92 mega-bytes of total disk storage becomes available.Two versions available: The kit H-37 Disk Systemcan be ordered with one (H5.37.1) or Nm (HS-37-2)double-sided floppy disk drives. And, the H-17-5double-sided 96 TPI disk drive can be obtained sep-arately for expanding your system as desired, See thechart below and the accessories list at the right formodel numbers and prices.

Flexible C BASIC Version 2.0 programming language• Includes a psuedo-code compiler and a run-time interpreter with

extremely versatile disk file accessing facilities

Structure: C BASIC consists of three programs. The first is a psuedo-compiler thatconverts your sou rce code into a series of coded operations and then places themin an intermediate disk file. The second. a run-time monitor, directly carries outthe operations included in the intermediate file. The third and final program,called XREF.COM , produces a cross-reference listing of all variables used in a CBASIC sou rce program. Files can also be directed to a printer.Expressions available: C BASIC statements and commands include string con-stants, integers and real numbers, identifiers, variable and assign statements.Some extended features include the IF, THEN, ELSE and WHILE constructs.integer variables. multiple line functions, chaining with common variables, addi-tional predefined functions and a cross-reference listing generator. To increase itsversatility. C BASIC uses machine language linkage statements and func-tions.. like PEEK. POKE, CALL, and SAVEMEM. Also. several control and I/Ostatements allow more sophisticated programming.Hardware and software requirements: To run C BASIC, an HiZ-89 Or X-90 Com-puter needs 48K of RAM, one floppy disk drive and the CP.+Ma operating system.An H/-100 requires one disk drive and CP/M.NCM-817-1, Vers. 5.2 on hard-sectored 5.25" disk, Shpg.

Microsoft* BASIC Compiler speeds program execution• Compile your programs with this MBASIC Compiler. Version 5.2, and

eliminate time-consuming interpretation

Increased execution speed: Compiled programs are fast because the BASIC Com-oiler produces highly optimized machine code which is directly executed. Duringthe compiling of a program, expressions are reordered to minimize temporarystorage and, whenever possible, to transform floating point division into multi-plication. Also. constant multiplications are optimumly distributed to allow for amo re complete and constant folding.To use: Simply enter and debug your program using a BASIC Interpreter. Thenenter a single command line telling the compiler what to compile and whichoptions to use. The compiler then produces optimized machine code as a re-locatable binary file. This object code is then loaded and linked with MBASIC'srun-time library. Included in this library isa relocatingassembler. a linkage gener-ator, a cross-reference generator, and a library manager.Hardware and software requirements: To run this compiler, an H2-89 or Z-90Computer needs 48K RAM, two disk drives, and either HDOS or CP/M-80.HMS-817-41, on hard-sectored 5.25" disk for HDOS. 4 lbs 250.00HM&837.41, on soft-sectored 5.25"disk for HDOS, 5 lbs. 250.00HMS-817.4, on hard-sectored 5.25" disk for CP/M-80, 4 lbs. 250.00HMS-837.4, on soft-sectored 5.25`d isk for CP/M-80, 4 lbs. 250.00

Powerful and versatile MACRO-80 Assembly Language• Provides most "big computer" assembler features without sacrificing

speed or memory space

Features: MACRO-80 supports a complete, Intel-standard macro facility whichaccepts IntelSOSOand Zilog 80 mnemonics. Nesting of macros is limited only bythe amount of memory and conditionals, up to 255 levels, can be nested. Code isassembled in relocatable modules that are handled by a link editor.Utilities: After a source program has been written, it must be assembled using theMacro Assembler. This results in a relocatable module which is loaded using theLinking Loader, LINK-80. The Loader also links these modules to any internalroutines that may be needed for execution of the relocatable module. A librarymanager. LIB-80. is used to create and modify libraries which a re then linked withcompiled programs. A cross-reference facility. CREF-80, is used to generate aspecial listing that can be used as an important diagnostic tool. Each sourcestatement is numbered with a Cross Reference number.Hardware and software requirements: An H/Z-89 or Z-90 Computer needs 48K ofRAM, one d isk drive (two drives are recommended) and either HDOS or CP/M-80.HMS-817.51, on hardsectored 5.25" disk for HOOS. 2 lbs. 65.00HMS-837-51. on soft-sectored 5.25" disk for HOOS. 4 lbs. 65.00HMS-817.52, on hard-sectored 5.25`disk for CP/M-80. 2 lbs 65.00HMS-837-52, en sofbsertored 5.25" disk for CP/M-80, 3 lbs. 65.00

Data management: Condor's Relational Data Base Management System(rDBMS') is a series of programs designed for simple and incredibly fast informa-tion storage, sorting and filing. RDBMS allows you to design and create files ofinformation, or data bases for keeping records on any subject you desire, With thissystem you can quickly search, sort, merge, analyze, index and print out anyrecords. Condor rDBMS is the data management system that simplifies informa-tion processing for inventory control, accounting functions, personnel reportingand many other applications.Fast operation: Written in Assembly Language, rDBMS operates much faster thanother data base managers. Since interpretation time is eliminated, commandsand operations are quickly carried out. Therefore, you spend less time handlingfiles within rDBMS's impressive data base capacity which can process up to32,767 records per file with up to 1.023 bytes per record.Powerful: While rDBMS is fast, it is also one of the most powerful relational database management systems available. With this system's outstanding capabilitiesyou can create new data bases within minutes, calculate statistics for field valueswithin a data base and efficiently post transactions toa master file. Other featuresallow you to produce sophisticated reports and multi-data base relationships. Thisprogram also has an index feature for quick access to information.Easy to use: Besides being powerful, rDBMS is so easy to use that a new user canachieve results within several hours. This is due to a number of built-in operatoraids such as help screens. command files and user-defined messages. Helpscreens simplify operations, especially if the same task is often repeated. Youdesignate what commands are to be contained in a menu which is acce ssiblethrough the keyboard. The commands (listed by a number) in the menu areactually files of commands required to perform an operation. So instead of usingmany commands for a single task, all you do is enter a number assigned to do atask. You can further simplify the use of rDBMS by creating different help menus.Available operations: With rDBMS you can perform addition, subtraction. multi-plication, divison and other arithmetic operations on entries. Julian calendardatesand dollar amounts. Quickly and easily select records by specifying up to 32logical conditions including the AND. OR and NOT Boolean operations. This database management software package also has extensive error checking ca-pabilities to help prevent clerical errors.Manuals and tutorials: One of the exceptional features of Cond or rDBMS is itsplainly readable and highly instructive user's manual. It is well designed with

proven, self-instructional text format and unit reviews

Managers, engineers, students and hobbyists will benefit fromthis broad, in-depth introduction to the interesting and chal-lenging science of lighhvave technology. Fiber Optics a re animportant, future•shaping breakthrough in rapid signal trans-mission with cost /performance benefits that promise to revolu-tionize the world of data communication. Be prepared for thefuture by educating yourself now.The five-unit Heathkit/Zenith Fiber Optics Course covers the

fundamentals of fiber optics. Unit 1, Optical Energy, deals with the nature of light.Just as electronics students need a basic understanding of atomic structure andthe nature of electrons. so does the student of fiber optics need an understandingof optical radiation. Once this is established, you will move on.Unit 2, Optical Fibers, describes the principles of the transmission medium. Youwill learn the various fiber types and their construction. how they propagate light.the importance of such characteristics as numerical aperture, source area andradiation pattern in the energy launch, and loss factors.Units 3 and 4 deal with the active devices used to generate and detect the lightused in fiber optic transmission. As you progress through the study of Fiber OpticLight Sources, you will learn much about light-emitting diodes. This unit coverstheir physical const ruction. theoretical operation, biasing characteristics andseveral types of fiber optic LED design considerations. A detailed discussion oflaser emission and principles associated with the use of injection laser diodes infiber optic circuits concludes the unit.Finally in Unit 5, Fiber Optic Systems, you will tie all of the component partstogether into an operational fiber optic link. You will examine the requirements ofthe various types of links and learn which components best fulfill certain require-ments. Four optional hands-on experiments a re also included in the course toenhance your understanding of the text. You will construct a modulated sourced river circuit, a fiber optic receiver circuit, and fabricate actual fiber optic links.These experiments will allow you to gain valuable design experience, and let youobserve the parameters of a fiber optic link directly. To perform them,uwill needeither a Heathkit/Zenith ET-3400 or ET-3400A Microprocessor Trainer or theET-32008 Digital Techniques Trainer. an oscilloscope. a multimeter and commonhand tools (not included). All other necessary pa rts such as ICs. transistors.resistors, capacitors, emitters. detectors, fiber, and connectors are furnished withthe course.In addition to th e tell, two supplemental appendices support the learning pro-gram. A listing of standard resistor values will come in handy when the student isbuilding actual circuits from mathematically-derived schematics. Typical datasheets for several fiber optic devices will help in evaluating your newly acquiredknowledge. A 25-page glossary of terms serves for quick reference .

• Nine-hand operability, including thenewly -allocated 10,18 and 24 MHzWARC bands and WWY at 15 MHz

Brave new Transceiver: The Heath SS-9000 isa quantum leap forward in terminal-controlla-ble communications gear. Consummate inevery engineering detail, its design evolvedwith the future of Amateur Radio in mind,and those operators who are exploring theleading edge of convergent radio and computer technology. Streamlined forultraordinary results even without keyboard control, experienced amateurswill ultimately use it to establish new high standards for performance.Completely synthesized for absolute accuracy: A crystal-controlled masteroscillator provides exact reference to phase-lock the BFO and HFO for superstability and repeatability. Likewise, a single precise VFO is tied to eachdisplay through 256 bytes of CMOS Random Access. Memory. This extendedon-board storage capacity accepts three separate inputs per band (preservedwith battery backup) for a total of 27 frequencies to recall and work at will.Two displays are better than on: Smart operators know our unique dual digitaldisplay is more than a cosmetic frill. Simultaneous working readout givesserious contesters and DX hunters greater advantage in frequency-handlingspeed and agility. Pushbutton exchange with (and copy into) memory oropposite display permits instantaneous 05V.. Place it under terminal controland you can enjoy a versatility in QS0 capture that shatters all precedent.The Terminal Interface: At the heart of your SS-9000, an "intelligent" control-ler circuit assists a serial interface in maintaining communications protocolbetween external requests, via front panel controls or terminal guidance, andthe internal circuits on the synthesizer. T/R and audio circuit boards. It allowstwo-way Control/monitor communication between the Transceiver and a videoterminal (such as the 112-29 on page 38), hard copy ASCII teletypewriter, orcomputer (such as the HS-89 All -In -One on pg. 36).Total contro l, simple controls: Commands are available to select, display andchange the band, mode. all 27 operating and memory frequencies. passbandshift, band scan and baud rates, lock and release one or all switches to theirterminal-controlled or physical states and print all parameters. Keyboardcommand also allows you to place the SS-9000 in transmit or receive mode,assign and toggle PR/ir status on the dual readouts, and freely manipulate thethree stored frequencies on each band, with full diagnostic error-promptingat the terminal. All keywords are sho rt , and easy to learn.An 5S-9000 can be connected to the Heathkit SA-1480 Remote Coax Switch.When changing bands (either manually or via remote control, using theMotorized Band Switch) the proper antenna is selected automatically.Free software: A 514' hard-sectored floppy diskette is supplied with everySS-9000. It demonstrates many ways of providing useful communicationbetween a computer and the Transceiver, using graphics and video text tointroduce you to its amazing control capabilities.The P5.9000 Power Supply/Speaker is a perfectty matched component As the55-9000 powerplant. it provides 13.8 VDC for base operation with hightemperature, short circuit and current surge protection.

HD-1418 multi-mode SSB/CW/RTTY Active Audio Fitter makes the tough ones easy to copy

$129' • Lowpass, highpass, peak and notch controls help you cus-

tomize upper and lower bandpass edges to isolate desirablesignals and reject heavy ORM

As today's bands become increasingly crowded, there's often a problem with toomuch interference to bother trying to copy a good signal. Heathkit has an easy,affordable way of effectively eliminating dogged interference — the HD-1418Tunable Active Audio Filter. It tunes out unwanted ORM and improves the selec-tivity of receivers by a remarkable degree.Twelve total poles of filtering can be combined to work as SSB & Notch, CW. CW2,SSB, 55(3 & Peak, RTTY and Fixed configurations with razor-sharp skirts. Bygiving full control over receiver bandpass characteristics, it can solve such prob-lems as partially overlapped sideband signals, overmodulation splatter, close-packed CW stations, lull RTTY reception through heavy interference, heterodynewhistles and noise that other filters find impossible to conquer.Simple to install — just plug it in between receiver output and speaker. Filter isbypassed when off. Input Overload LED glows if signal exceeds 3 volts, so you canadjust output receiver gain for undistorted response.Versati le power requirements make this Audio Filter usable almost anywhere. Justsupply 7 to 13.5 VAC or 9 to 18 VDC, at 400 mA. For VAC operation, use thePS-5012 Power Cube on page 95.kit HD-1418, Shpg. wt. 3 lbs. 129.95
