I have a drawer full of 160, 80 and 40m crystals, including most of the
popular AM frequencies, but they work in only one of my transmitters,
but I have something to keep me on the air in case the VFO craps out. I
modified the Gates BC transmitter to run off an external VFO, and it
won't operate xtal control any more. I sometimes run the HF-300 rig on
crystal just for the fun of it. Most of my xtals are the old round
Bliley/Valpey types that fit into a 5-pin tube socket.

So, any Advanced licensee had to have passed the 13 wpm code test? I
wasn't sure whether or not those changes all occurred in one sweep.

Both my homebrew rigs will work multiple bands, but the Gates works only
160m. I find it easier to tune one of the HB rigs to 40 and the other
one to 80. Then I just fire up whichever rig is tuned to the band to the
band I want to get on. I have to run down to the tower to switch
antennas, but once selected, the tuner at the tower can be remotely
adjusted from the operating position using a reversible DC motor and
I can tune equally well all way across any band. One of the excuses I
frequently hear for not operating outside the window/Ghetto is that the
antenna is resonant at 3870-90 and won't tune "down below". I prefer by
far one good, solid, high antenna fed with resonant feeders and a tuner,
to a forest of coax-fed half wave dipoles for each band, even incuding
separate ones for 80 and 75m, cluttering the space over the shack.
