[TenTec] 565 Orion I internal keyer problem. experience? advice?

[Katz Ajamas <ajamas.rn@gmail.com>]

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.
