Have you ever wondered what good one of those $60-100 "R X Noise Bridges" could do for YOUR station setup? Are you baffled by your antenna tuner or "transmatch"? The 1051 is easy to build and super-easy to use. No "R-X" controls, calibration or calculations needed. Just connect it between your rig and antenna tuner, set receiver to desired operating frequency, and adjust the antenna tuner until the distinctive modulated pulses (NOT just straight "noise"!) drop to an easily-recognized "null" indicating that the tuner offers a 50-ohm match to your transceiver with NO on-the-air nervous experimenting with the tuner controls!

No. 1051, $17.00 Foxhunt "Beep-Beep" Transmitter (for FM Broadcast Band) Here's a great gadget at a great price for clubs, classes, scout troops and packs, camps and family fun! Tune it to any quiet part of the 88-108 MHz FM band per FCC Part 15 rules, noticing its distinctive "beep-beep" modulation, and let the kids use their own FM portable radios to discover the basics of direction-finding. Hide it indoors on rainy days! Includes board-mounted on-off switch and 9V battery snap. Use several to demonstrate triangulation. T-KIT No. 1058, $12.00. A classic circuit and a nice price make this a great project for beginners or for building into extra rigs. Includes speed control, weight control (rarely offered in "simple" CMOS circuits) and sidetone pitch control. A lot of keyer for the price, it features self-completing dits and dahs for standard single-lever keyer paddles. While not designed for iambic operation, the price and reliability make the 1553 a very nice introduction to electronic CW keying. T-KIT
No. 1553, $12.00 A New World of Budget-Priced Receiver Projects!
Universal BFO for SWL Receivers Got an old (or very new) AM only shortwave radio with no CW-SSB capability? If you want to enjoy casual CW-SSB reception, this varactor-tuned 455 KHz oscillator may be built into larger receivers or else mounted in its own case and placed near your portable SWL radio. The on board tuning control compensates for alignment variations from one receiver to another in addition to permitting fine-tuning of SSB/CW signals. Operates on 6 to 15 VDC. T-KIT
No. 1050, $9.00
Regenerative 4-Band SWL Receiver (Kit Includes drilled, painted, silkscreened aluminum front panel!) Here it is: PROOF that the classic "first receiver" project need not be more expensive today than our favorite 1950's kits. In fact, this great little receiver beats the pants off those 3-tube radios with the big plug-in coils. Excellent for clubs, classes and family activities. Band coverage: 49 Meter SWL band, 40 Meter ham band, 31 Meter SWL band, plus exciting 12-15 MHz tuning for daytime shortwave listening, 20 Meter ham band and all those other magical shortwave sounds. The sharp-looking front panel gives the "real radio" look right away: dress up your project later with a case and knobs, and perhaps a speaker. You can enjoy the basic kit just by hooking up 9 to 12 volts DC, setting up a modest wire antenna (10 feet or more of hookup wire) and plugging in your own stereo headphones (1/8" plug). Features convenient push- button bandswitching, on-off switch, "on" LED, tuning, volume, regeneration control. T-KIT

ANY
BAND" Direct-Conversion SSB/CW Receiver This is your best buy, by far, in a ham band direct conversion receiver kit. It has better audio and filtering than the others, and we supply the parts and instructions to let you build it for (or change it to) ANY band of your choice. That's Right: YOU choose the Band! Many hams KNOW that there are only minor coil and capacitor differences in the simple RF input and oscillator sections of a basic direct-conversion receiver. We give you ALL parts needed to build for your choice of 160, 80, 75, 40, 30, 20, 17, 15, 12 or 10 meters! Try out your own multi-band switching ideas. Start planning a budget priced QRP transceiver that will really WORK! Note to Beginners: Contrary to some advertising claims, a direct-conversion receiver is very good for CW/SSB but cannot provide very pleasant listening for shortwave AM broadcasts (BBC, Radio Moscow, VOA, etc.) For general listening, we suggest T-KIT Model No. 1054 or No. 1253.

No. 1056, $29.00 If you've been curious about what an "Active" receiving antenna can or cannot do, without paying the $40-$100 cost typical of both kit and manufactured units, you will enjoy the experience of building, learning about and using this very simple, budget-priced kit. Just for fun, we carefully tested this little T-KIT 1552 Module board next to active antennas sold by Heath, MFJ, Ramsey. Wow: you'll get the performance without the price tag! Bring ANY HF receiver to life with the 1552 and a small length of wire, or a simple whip antenna! Compact 1.75" square board can be mounted inside receiver or in its own small box. Circuit includes gain control; operates on 6 to 15 VDC. T-KIT
No. 1552, $12.00 Universal Low-Noise Broadband DC to 1 GHz RF Preamp You KNOW that every kit company sells some sort of .broadband preamp for all purposes. If you want to try a broadband, untuned RF preamp on any receiver or scanner or other instrument, THIS one is your best buy! Excellent noise figure, gain and frequency coverage at a BUDGET PRICE. Up to 18.5 dB gain at 100 MHz. 17 dB gain typical at 500 MHz. Supply voltage: 8-14 VDC. T-KIT No. 1001, $9.00 Need a quick, reliable, inexpensive audio amplifier stage for that homebrew project? This careful design gives your project the very same audio output circuit that we use in today's TEN-TEC transceivers! Enjoy 1.5 watts of low-distortion audio with no worry about motorboating and other unwanted oscillations. Includes optional preamp input for 10 dB gain. Important: this circuit is designed for 12-15 VDC. T-KIT No. 1550, $10.00 While speech processing IS a standard feature of taday's SSB transceivers, there's plenty of nice equipment at hamfest flea-markets which can benefit significantly from the addition of this proven speech processor circuit used in all of today's TEN-TEC transceivers. If there's room, build it into that older rig. Or, design it into that audio console you've been planning, or just use a neat TEN-TEC box! T-KIT
No. 1551, $l2.00 High-Power
Variable Capacitor What? Me BUILD a capacitor? Air-variable capacitors cost $$$ these days because of all the hand labor of putting them together. If you'd like to spend part of an evening reliving those grand old Erector Set days, save money by assembling your own high-power variables from our top-quality factory-ware. Build the same tuning capacitors used in world-class TEN-TEC 1.5KW RF amplifiers and tuners. Great for all hi-power homebrew projects, including experimental loop antennas. KIT No. 1207, $49.00 (TEN-TEC assembled No. 80-858, $74.00.) A Neat Bonus for T-KIT Buyers from the TEN-TEC Equipment Enclosure Division!
