Re: Kanga UK 5 MHz Crystals
Hi Chuck,toggle quoted messageShow quoted text
My old Kenwood Twins, around about 45 years old now, has five xtal sockets that allow ~5 mc xtals to stand in for the VFO. The rig is dual conversion with the SSB generator and xtal filters at 3.395 mc and the second conversion is a 600 kc wide "bandpass" filter in the 8 mc range. If that 8 mc filter will pass the 60 meter energy from the 75 meter band the xtals could be used that way. The VFO range is from 4.9 to 5.5 mc.
Somebody else mentioned using converters or "transverters" and no reason that can't be used if we watch out for possible spurious signals too close to the operating frequency to filter out. There are useful charts in the ARRL Handbooks (and others) to help choose frequency combinations with fewer problems. Those will be in the receiver discussions but it all applies to heterodyne transmitters, too. A converter or transverter may be viewd as just an addition conversion stage in either a receiver or transmitter. It's all doable.
