One more thing I forgot to mention............I am also adept at aligning
all Drake receivers, up to the '7 line.
Thanks!

Hi folks,
My job at at my present employer is winding down, so it
might be time to market some of my other products and services.
Would there be interest in.............................
1. a DDS based AM signal generator, tuning steps down to 10Hz, coverage
from 10Hz to 30MHz. This could go all the way up to 60MHz.
2. A DDS based VFO that has programmable offset for the displayed
frequency............good for an LO for your receiver experiments.
3. A DDS based replacement for the Drake FS-4 synthesizer, that has a
projected price of about 130 dollars. Some of you Drake list folks may
have seen this inquiry posted by Dan.
4. Receiver mods, such as attenuator removal, etc. I could do audio mods
to receivers, but since Craig, over at Kiwa is already doing this, I
don't want to encroach into his territory. I have spoken to him in the
past, and he is a good guy, as well as being a straight shooter.
5. Receiver characterizations, such as sensitivity, overload point,
distortion measurements. I have all of the equipment necessary to do
these characterizations. Price for this service would be 30 dollars, plus
shipping.

There are quite a few ideas that I have, but if there is some kind of
service you are looking for, please e-mail me directly and let me know. I
can do some receiver repairs, including the Lowe HF-150, and I can align
just about any receiver, including the old tube boatanchors. I have
restored and aligned: all Hammarlund receivers, most of the Hallicrafters
and National receivers, Collins receivers.
I am also set up to do stereo FM tuner alignments. I can verify stereo
separation up to at least 65dB, and distortion measurements down to
0.0015%.
Before I started designing radios, I used to design and build custom
audio equipment for folks.
Thanks for looking at this post................once again, it would be
good to contact me directly so that I don't end up starting a long
thread, but I will check this one from time to time.

Pete


I think there is actually a market for all of the above, Pete.

BTW - I saw your post about the Cedar Rapids Hamfest. We probably walked
right past each other a dozen times or so, but didn't know it. (I lived in
Dubuque
a few years ago)
