[GreenKeys] New RTTY Handbook TU's

[Tom Hunter]

I already have those pages scanned. I save as BMP's so the schematics are clear. That makes them pretty big.

If Someone would like to put my scans on their website including the pages on adjusting polar relays, I could try to get them to him.

Another TU circuit in that book used a balanced circuit to operate a polar relay as its loop keyer. In my opinion, a much better use for the relay than destroying it. I have also scanned that article.

Years back, the "New RTTY Handbook" had a few pages dedicated to making
a Terminal Unit and fitting the entire thing into a Polar Relay enclosure!  I 
don't recall much else but it was an interesting idea.

The design was on a PC board and wires went from the board to the pins inside
the relay device.  If there is any interest, I will dig up my copy of the Handbook
and scan the few pages involved with this project.  If nothing else, it will be a
perfectly good use of a Polar Relay (enclosure).  Doing this will also require a
Polar Relay socket.
