I reckon that if the sideband selection was fully in-line with the reality of our conventions that they wouldn¡¯t have needed the lamps and we would be simply selecting manually ¡ª like with the transmitters.?
I have no idea what costs were in 1963, when the original design was done. Two more crystals in, say the late 60s and 70s probably would have been cheaper than all the switching, lamps, etc would have been. Today, of course, crystals are more expensive again.?
Drake wasn¡¯t the only manufacturer that used this scheme ¡ª I believe that Swan did, also, as well as other companies.?

Thanks for that clarification! ?
This is what I was looking for.

The indicator should not be interpreted as automatically selecting the correct sideband.?

You can tune up on either sideband using TUNE, which is an audio tone.
X is always used for CW which offsets the carrier oscillator to put its signal inside the passband of the filter (LSB filter I think).

20meters is the only odd ball band that uses the filters backwards (uses LSB filter for USB).? That is the only band that tunes
backwards on the PTO dial.
