I had posted this elsewhere, and it has created some interesting feedback.
Based on Wes W7ZOI's Progressive RX from the late 1980's. A wonderfully
balanced design to which I added some bells and whistles I like in a
receiver.
These are some shots of my almost finished 1980's theme HF receiver.
All stainless hardware, teflon wiring. Rock stable VFO, homebrew xtal
filters ( 5/2/5/0.5), selectable and defeatable AGC, notch filter, tone
control, QSK input,built in front end BP filters for each band,
preselector,
AM/USB/LSB/CW.
Enjoy:

Dale -

Very nice. Looks like you built the RX .. that I am still designing since
1980 and reading Wes' articles. :-)

I see you used a 9 MHz IF.
Any particular reason that you used separate (LO) oscillators for each band
(rather than a single oscillator with switchable crystals) ?

The cabinet look a bit like some LMB enclosures.
