Homebrew RX
I had posted this elsewhere, and it has created some interesting feedback.
Based on Wes W7ZOI's Preogressive 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.

That's fantastic Dale. How much time you got in it. -- 73 and good DXing. Brian Hi Brian, I did not keep track- but would guess over 200. Laying out the front panel and milling it had to be 6 hrs at least. Even cutting the recatngular slot in the Eddystone backplate for the S meter was hours, as I could not simply clamp it to my mill table what with the pulleys etc being riveted on. Layout of the SCAF/ AM demod board would have been a lot easier in surface mount, but would have deviated from the 1980's theme- that is one packed board Not a cost effective way to get a receiver- but then again, I got EXACTLY what I wanted.

That's a thing of beauty. Must be a lot of fun to operate.

Wow Dale real nice work. Imagine if some company licensed your design.. Lucky |

All that great work and NO DIGITAL READOUT?????? :) I have pretty much zero fascination with a digital readout- that would have been the easiest part of this receiver- and would have absolutely ruined the front panel. I can resolve pretty close to 1KHz as is, allowing me to find whatever I need. Just my opinion. Dale W4OP |
