Re: 80 meter superhet
At risk of wading in over my head here......
Why does the IF frequency matter?
If the IF is 11Mhz, and it has enough gain at that frequency, then why not use it?
I wonder if the mixer circuit is efficient, and has been redesigned for the new IF?
Granted, it is much easier to get good stable gain at lower frequencies, but I can't see a problem with the chosen IF in this design.
Just my thoughts on the matter.....
