[Orion] Re: Orion raspy on CW? (Charlie, W0YG)

["D.W. Fearn" <dwfearn@dwfearn.com>]

A few months ago I was getting reports of awful keying with my Orion.  Some 
described it as "fractured" and un-readable.  On 80M one guy about 200 
miles away said I had key clicks over the entire band.  The sidetone 
sounded fine.  No reports that it was raspy, however.

This went on for a while as I experimented into a dummy load and listening 
on another receiver.  The keying was definitely bad.  This persisted 
through a couple of firmware updates.  I talked to Ten Tec service about it 
and they were convinced it was a bad coax.  But it wasn't.  The rig seemed 
to be generating huge spurious outputs because into an antenna the 
reflected power on a separate SWR bridge would kick violently only on key 
release.  (It was fine into a dummy load.)

I was about to ship it back for repair when the problem suddenly went away 
and has never returned.  I had changed nothing that I am aware of.

There are still some CW issues for me: about once every 15 minutes, the 
keying locks-up momentarily.  Makes me sound like a fool.

A more subtle problem is evident when I am using a bug.  I think there are 
times when the microprocessor gets too busy to follow the dots and the 
spacing is affected.  It's not too obvious, but I notice it.  My old 
Corsair II doesn't do that, nor does my ancient Viking Valiant.  The old 
rigs do not shorten the first element, either.

The keying seemed to be much better when I first got the Orion.  Perhaps 
some firmware updates have had unanticipated effects.

I have faith that Ten Tec will solve these problems.
