[Boatanchors] Atlas RX-110/TX-110

[N4ch at aol.com]

Hello Dick (and others).......
 
I have an original set of docs for both the TX-110 and RX-110;  you are 
correct in your saying the transmitter came in two power  levels.   The high 
power one did about 80-100 watts out, and the lower  power one did typically 
5-8 watts, and since the low power  model didn't draw a whole lot of current 
it could be run off the power  supply in the RX-110 receiver.   If a high 
power transmitter was used  with the RX-110 then you would have to supply 
12-14 volts at around 18-20 amps  additionally, to run the final PA stage.   Let 
me know what docs U  need, and I'll get to work on that.
 
BTW, at the bitter end, Atlas sold a FEW receivers called the  "RX-110 
Special".   I don't know whether or not it was ever  advertised; I have never 
seen an ad for it, and I don't think they ever printed  a manual for this 
receiver either.   They MAY have printed a sheet or  two describing the 
"enhancements" over the "plain" RX-110, and shipped a  standard RX-110 manual and 
this extra sheet or two with the "Special" when  new, but I've never seen a 
thing in print for this model.   The  "Special" offered a couple of 
enhancements over the "standard" model, most  notably a CW filter function (actually 
this was nothing more than a few varicaps  and resistors to "narrow up" the 
existing 6 pole SSB ladder filter that all of  the RX-110s employed) and they 
also added an RF gain control and a simple RIT  circuit..........none of 
these functions were in the "plain" RX-110.    Adding a crystal calibrator and 
an "S" meter would have been nice, but these  enhancements were not added; 
apparently they would have added too much to the  cost.   I'd be interested 
in getting a copy of whatever might be out  there as far as a promo sheet or 
a manual for the RX-110 Special goes, if anyone  out there has anything.

A nice  clean looking, albeit with problems, set went over on the "evil
empire"  yesterday. I was tempted enough to put in a snipe, at what I
thought was a  high level. Turns out someone wanted it more than me.

It was an  interesting piece and perhaps this sale will bring out a few
more from the  closets.

Research tells me the TX-110 came in two flavors, 10 watt out  and
100 watt out. It looks like a drop in amp board went into the  XMTR.

Does anyone have any original schematics for these ? The only  one
I found on the web was a pretty poor copy. Maybe someone has a  set
they would part with ??
