With the keyer enabled, there is a continuous stream of dashes.
I do not see 5V on the ring of the paddle connection.
I do see 5V on the tip.
If I ground the tip, alternate dot-dash results.
If I provide 5V, through a 10k R, to the dash line, there is no difference.
This suggests that the line is being pulled low somewhere.
There is a keyer interface shown on the A7 diagram "81917_4 Drivers some
spares".
Alas, Tentec does not provide photos of the boards showing parts location.
I would rather be working on other projects and am willing to make someone
a good deal on this 565.
TX works.SSB and CW.
Main RX works.
It has 4 filters. AM SSB 1.8KHz 1kHz
New battery for memory.
Sharp display.
