Transmatch Tuning Bridge

Have you ever wondered what good one of those -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! We recommend (undrilled, no holes) enclosure TPx-15 for this item. Order TP-15 for unpainted aluminum, TPB-15 for black, TPC-15 for charcoal.

Universal BFO

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. We recommend (undrilled, no holes) enclosure TPx-13 for this item. Order TP-13 for unpainted aluminum, TPB-13 for black, TPC-13 for charcoal.
