SIX METERS IS ONE of the finest mobile bands we have these clays, particularly if you aren't planning to spend several hundred dollars in a sideband transceiver. It is virtually impossible to find a section of the country remote enough to be without contacts and the in frequency of band openings assures you of QRM free local contacts most of the time- Six meter mobile is not only one of the best bands for keeping in touch with the local gang, but if you do any traveling it is the finest for...

The first step in tuning the converter section is to adjust L-6 for proper oscillation action. The simplest way to do this is to tune a communications receiver to 2.9 mc and adjust L-6 until oscillation occurs. Adjust for peak output consistent with rapid starting of oscillation upon application of plate power. If a signal generator is available, set it for approximately 3,9 mc. With a broadcast receiver connected to the transverter, tune for the 3.9 mc signal in the vicinity of 1000 kc on the...

Wire it all together as shown in Fig, 13. The high voltage is stolen from the transmitter supply, and should be somewhere between 400 and 1500 volts. Only a few mils are needed, but since the transmitter supply can produce much more, take extra care with the wiring to make sure youll never be able to get across the high voltage Resistor values shown in the schematic are for a 5CP7 with 750 volts applied to the HY input for other tube types or other voltages, you 11 have to refer to the tube...

Roy E Pafenberg W4WKM 316 Sfratford Avenue Fairfax, Virginia Photograph by Morgan S. Gassman, Jr. is not good enough and the choice of a dynamic or crvstai microphone is made for surplus conversions. In this case, the usual course of action is to rip out the existing audio input circuitry and install a vacuum tube speech amplifier. The little device shown in the photographs is a much simpler answer to the problem and requires a lot less work. The output of a low impedance 50 ohm dynamic m...
