Hi Bill, another great SS.
ReplyDeleteIf ever you want to upgrade the receiver in the kickpanel rig (and move towards more discrete parts), I highly recommend another Farhan receiver at http://www.phonestack.com/farhan/dc40.html It has a better front end than the NE602, and I think nicer audio. I describe and demo my version at http://www.youtube.com/watch?v=Tc2ofe7T7Rw
I can't resist ending by questioning the 2006 Handbook quote about LSB/USB use being due to 9 MHz crystal filters and 5 MHz VFOs.
You'll only get sideband inversion if you're subtracting the crystal filter frequency. Subtracting the VFO won't invert the sideband. Eg if you have a 9 MHz USB signal and mix it with a 12.5 MHz VFO, you'll get 21.5 MHz USB and 3.5 MHz LSB.

Congratulations, I just started listening to SolderSmoke Podcasts but definitely love them. Time to time, I have to admit, I got confused with words (I'm Italian).
ReplyDeleteLook forward to follow you and your blog.
Cheers from Italy
