The left x-tal is not a FT-243, but similar and it can be used in a BC-620 with 79 channels, 100 kHz separated, in the range 20,0-27,9 MHz. These FT-243 x-tals are numbered after their channel,  so channel no.65 means the fundamental frequency of 7873,3 kHz multiplied by 3 + the IF frequency of 2880 kHz, giving  a working frequency of 26500 kHz.

The middle and right x-tals were used in the BC-659 and BC-1335 with 120 channels, 100 kHz  separated, in the range 27,0-38,9 MHz. These x-tals are numbered after their working frequency, devided by 100, so channel 292 means the fundamental frequency of 6225 kHz multiplied by 4 + the IF frequency of 4300 kHz, giving a working frequency of 29200 kHz.

 Hello Jan,

with all respect, but I disagree. The FT-243 is the designation of the crystal holder, not of the crystal itself. FT-243 specifies the size of the holder, pin diameter and distance, size of crystal that can be accomodated and also electrical characteristics of the holder. All other data refer to the specific radio sets the crystal (in its FT-243 holder) is meant for. The same applies to FT-171(-B) crystal holders.

Dear Goetz,

Thanks for your explanation, and sorry for my mistake.

The Crystal Case CS-137 was used to store those FT-234 mount crystals used in U.S. military transmitters / transceivers (e.g. the BC-659 transceiver).
