[Kenwood] Difficulty keying linear in CW with TS-850

[Vince Shirley]

Hi all,

I've just acquired a TS-850 for a very good price and am pleased with it in
all respects with the exception of one item.

When attempting semi break in on CW, the rig keys the linear OK (ground to
transmit) but there is no RF output and the rig emits a fast "chattering
relay" type of sound.

If I manually ground the linear, or use the rec/send switch all is OK on CW
as it is in SSB.

I've experimented with SW1 (external/internal keying) which doesn't make any
difference (neither did I expect it would) and the VOX hang time doesn't
seem to make any difference to the problem either.

Am I right in thinking that the fact that that there is no RF would indicate
that its either seeing an open circuit or the switching time is too slow.

Anyone any ideas ?
