Dale W4OP,
Dale,
I believe you posted an e-mail and a link to QRP-L a while back to show
your receiver. Should have said this before but better late than never.
Nice job.
If I remember correctly you used a basic 160M receiver with multiple
front end convertors. Also I believe you used blue backlighting?

Hi Don,
Thanks for the kind words. The receiver is based on W7ZOI's Progressive RX
from the late 80's. To Wes's excellent design I added,
S meter
AM detection
LM386 for loudspeaker w/ tone control
audio notch filter
Homebrew 5/2.5/.5 xtal filters
fast/slow/off AGC
80M RX with xtal controlled converters for 160/49/40/20/15/10ABC
The VFO drifts a little over 150Hz in the 1st 5 minutes then settles down to
+/- 20Hz in a 5 minute period. Wonderful sound and gets more use than the
PRO II
73,
