Ron -
I don't recall just how much LO is available, but I'm pretty sure a
Mini-Circuits SRA-1H or SRA-3H would work just fine in that spot. The
CM1 is long gone....
Maybe one of the TR-7 guys can be more specific. The SRA mixers are
readily available and Mini-Circuits has a provision for single sales for
hams.

All, I am looking for the balanced modulator, CM1-HF, which
is found in the Drake TR7 up-converter board. I have
searched the Internet with no luck. If anyone has one or
knows where this part can be purchased please let me know.
As an alternative, if anyone has an up-converter board for
sale, let me know. E-mail me at [email protected]
Thanks, Ron / WB4HFN
