Looks like you have received good information and I think you will enjoy the TO keyer. It will key any radio. ?Boat Anchor or other. One difference is that it doesn¡¯t have self completing dits and dahs so you need to keep the paddle making contact throughout the dit and especially the dah or it will be cut short and sound like a dit. ?I wish someone would talk about the history behind the HA-1 ?T0 keyer. Was his call K9TO or something like that. I talked to the inventor¡¯s son once and he told me about his father who got credit for the invention that Hallicrafters manufactured and sold thousands of units.

?There is a good manual on BAMA.
Paddles can be connected via a 1/4 inch TRS "Stereo" plug on the
panel or via wires to the octal accessory plug on the back. Sleeve is
common, dash is the ring, dot is the tip.
Out put is via the octal plug on the back, pin 2 is the relay contact.
There is a 1/4 inch jack on the back for headphones or external
speaker.
Keying is via a mercury wetted relay, will key almost any
transmitter. Relay must be vertical.
Octal plug also can be used to connect external speaker, a diagram
is given in the handbook. I am attaching a copy, if its not too large.
These are good, simple, keyers.

I was given a TO keyed that is in great shape except for a broken knob.
It appears to work too with? paddles plugged in and headphones it keys
OK and sounds good.? But even though I found and downloaded the manual
I'm confused on how to wire it to a rig - for example a Kenwood
TS-530S.? There is an Amphenol jack in the back but no matching plug.
From the manual it appears that I use pin 2 and ground for output?? But
I'm not sure and I don't want to mess anything up!? Help please.
