Visual CW Tuning Indicator
Many transceivers set the CW transmit off-set equal to the set's sidetone frequency. But it was left to the operator how to match incoming signals to the sidetone for one-frequency QSOs -- an awkward and time-consuming procedure
Wide-Range Antenna Arrays For the Roanoke Doppler
Doppler units are the "weapon of choice" among mobile T-hunters in many parts of the country. They indicate the direction of incoming VHF signals on a circular ring of light-emitting diodes or a digital display
A Complete 13.8 Volt, 20 Amp PSU
Power supply interested in a 13.8 volt, 20 amp P.S.U. which is suitable for powering the average solid state HF rig or 100 watt VHF/UHF
Build a Saltwater Dummy Load
Certainly any reasonably sized load will work up to 30 MHz, up to 50MHz is possible if care is taken in it's construction
