I'm considering buying an IC-756. I have a question about IF filtering:
The radio allows one optional filter in each IF, 9 MHz and 455 KHz. I
operate both SSB and CW. Would I be better off putting the 1.8 (or 1.9) KHz
SSB filter in the 9 MHz or 455 KHz IF, and vice-versa for the 500 Hz CW
filter? It seems to me that I want the CW filter in the 9 MHz IF to keep
everything else out of the passband/AGC, but does that mean there will be a
lot of hiss because there's no narrow filter at 455 KHz?
I'll summarize the responses if you reply to me and there are enough.
