[Premium-Rx] RACAL RA6790/GM Collins mechanical filter coupling caps

[Craig Anderson]

I have a 6790/GM which like many others out there is missing the USB and
LSB filters. I have a set of full Collins mechanical filters from a donor
RA6790 radio and I would like to use the USB/LSB mechanical filters from
that radio in my 6790/GM. I have been looking for information regarding the
value of the coupling caps needed for installing Collins mechanical filters
in a receiver that has factory crystal filters.

Thanks,

Craig W9CLA
