Hey,
Isn't that the same mech assembly used in the elusive Fowler R390A??

Fascinating. Makes the 390 gear trains look downright elemental by comparison :)

How about the Babbage Differential Engine?

If you are ever in the San Francisco area, this alone is worth a trip to
the Computer History Museum in Mountain View.

That's kind of creepy.

I've been intending to try this...? How wide of a frequency range around 455 KHz
will the Softrock cover??

This year at Dayton I spent the stately amount of $21 for a Softrock Lite II
kit.? I finally got around to building the thing this weekend, I can say
that I am totally impressed with the performance.? I am using it with a Dell
OptiPlex 755 I bought at Micro Center at as a refurb with Windows 7 for $260
and version 2 of Simon Browns SDR-Radio.? So even assuming the eBay price
for a CV-591 ranges from $250 - $500, I think the softrock is a great
solution.? I know this is heresy but this just adds a whole new dimension to
my 390 experience .? 73 .? tom, N3LLL

It is limited by the IF filter, I have been running it in the 16KHz position.
There were times when I could individually select any one of 3 SSB signals in
the bandpass as well as numerous CW signals. So I have been tuning close and
using the software for the band spread.
I think the non "A" may even be a better candidate since the hard filters are in
the software, if you have a decent PC in the shack $21.00 isn't a big investment

If you pick the signal off of the last if tube prior to the filters, you can
significantly improve the bandwidth. Just use a piece of copper sheet
wrapped around the exterior of the tube. Bernie W8RPW----- Original
