Try the ferrites. I include below a note from the RTTY reflector about a
cheap source of them. I just ordered a bag.

Subject: [RTTY] Help with keeping RF out of PC
Peter,
I sent you an e-mail the other day with a link to a web page that would
help
with your RFI. I was having problems myself at the time that I sent the
e-mail to you and was looking for a fix myself. I was doing everything
that
Jim says to do all of his web page at:
www.radioworks.com I put two Line Isolators, one between the radio and
amp,
and one between the amp and tuner. I really don't know if they helped me
or
not. Because, my problem was with my computer locking up or going crazy
on
me on 80, 40 in 160 meters. It still did it after I put them on. I had
ferrite beads on some of my equipment for a longtime and they seemed to
help
but, they were expensive at RadioShack at $4.95 apiece. Then I bought
some
from radioworks.com at $2 apiece and they seem to help even more. THEN, I
found this on eBay:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=5743889061&ssPageNam
e=STRK:MEWA:IT
I got them in the mail a couple of days ago. They were shipped superfast
by
this guy. I started clamping them on every cord on the back of my
computer,
monitor, mouse and keyboard. Two or three of them on every cord there
was.
I had 100 of them and I was on a mission. I had about 25 ferrite beads on
my radio's and knew they were working. I was just tired of paying so much
for them. I used about 20 on my computer and still have about 80 left. I
was on 80 and 160 this evening playing with the contest.
I didn't pay much attention to any thing because I was running low-power.
But, then Easter Island came on and I kicked the amp on.
About 1200 watts and my computer didn't do a thing. I was shocked! No
lockups! No windows popping up! So, I played more.
As far as I can tell the ferrite beads took care of the problem but, I am
still in the experimental stage. I'm going to clip the rest of them one
everything in the shack. The wife and kids better run!
Well, it's 4 a.m. in the morning and I'm shot. I just had to pass this on
to you. I thought it was a great deal. 100 ferrite beads for $27. And
hopefully no more RFI problems. But I'm sure that Murphy is still running
around here somewhere. I'm going to put a ferrite core around his neck.
.
I am in no way affiliated with radioworks.com or the guy that sells these
beads. I'm just excited!
Good luck and may we have a RFI free 2005. hi hi

Subject: [TenTec] Orion reset
I have had the Orion for 7 months. Its receiver is
very immune to overload and adjacent channel
inteference.
My unit seems to mute on receive or transmit, more on
receive, every 2-5 hours during contest operation,
requiring master reset, which takes aroun 2.5 minutes
with user memory restore. There were 7 resets for
CQWW SSB and CW each. This muting always occurs at the
maximum contest rate, and is disruptive. I think this
is the "Achilles heel" for this rig. It has been
suggested to do all keying from the front panel by Ten
Tec(disabling th on-board keyer), which does not help.
The 1.372 firmware does not help.
Any comments? Do I have a defective unit?
73,
John K3MD
