Well Dale it looks very nice and obviously works well too. I thought I
remembered you saying the Progressive Receiver. I am glad I had a
chance to compliment you.

Since the subject was the Eddiestone dial I expect that was probably a
chore to install. I usually build homebrew dial chord and drum
mechanisms and more recently use the flange type Jackson Brothers and
Oren Elliot drives. I just figured out a way to make custom dial
plates. Probably an old idea but new to me.

I just finished a 40M receiver for a SSB transceiver. I thought about
using a small blank CD for the dial plate. What I ended up doing was
getting a piece of brass sheet from ACE Hardware and using a 2 1/4"
hole saw (my chassis panel is 3") I cut a round disc. I had a small
amount of deburring to do but the brass is way tougher than aluminum
and a simple file removed the burrs. The 3/8" drill bit also provided a
true center for the dial plate. I polished it with super fine auto
rubbing compound. I ended up with a nice dial plate.

I need to mount it to a small shaft section of a vernier capacitor from
Ocean State Electronics. I took a shaft coupler, the type with
removable couplings on both sides, and using very tiny scews mounted
this removable portion of the coupling to the plate.

Its hard to describe. But I am pleased with myself as I a mechanically
weak.

This is a good method for making custom dial plates. I had to use a
good chord type drill as my cordless was getting warm. I also mounted
the plate for drilling using two wood screws and fastening the uncut
plate to a scrap 2 x 4 by drilling holes slightly above and below my
cut.

Now I gotta figure out how to mark the plate. Well maybe I will catch
you on the air sometime Dale.

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?

Don,

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,
