You will have to move the crystals from the 32S to the 75S for
transcieve. That connection uses only the crystals in the receiver, none
in the transmitter.

My 32S-1 manual says the meter has a 1 ma. movement.

Burghardt Amateur radio in SD has had Collins Crystals. And then there
are the gold plated ones at Surplus Sales near Omaha.

I think most US crystal makers can make them custom, primarily need to
be 3.155 MHz above the low end of the band, though are half that
frequency when above 13 or 14 MHz. In my experience, most any crystal in
the 6 to 15 MHz frequency range will work, though without the 3.155 MHz
offset from the lower band edge, the dial calibration isn't as
convenient. I don't know if they need to be 20 or 32 pf load for
parallel resonant operation. The crystal makers should know that
already.
