I have had my Orion II now for almost two weeks and the bug showed up last
night three times. Each time the S-meter froze at a high reading and the
sweep went off. Each time I simply turned the rig off and then back on and
it was back to normal. The time internal between the freezes varied from 30
minutes to up to 60 minutes. That was the first time I had observed the
"bug" after normal operation for a week or so.
For those of you into HF DX, the 80M band has been open to Europe the last
two nights and I was able to hear very weak stations on the Orion II that I
could not copy on the Icom 756 Pro II, beside it, and using the same
antenna. The Orion really showed its low noise floor in this comparison.

Shortly after I said that the ram clear fixed the problem, it did it again!
Should have kept quiet. I was in screen color selection #3, had been using
#4 for a week or so. Don't know if the color selection has anything to do
with it or not.

George:
First from my point of view, 4:1 baluns should not be used in this
application. I wouldn't expect it to work. Based on your antenna/feedline
configuration the actual feed Z of the antenna may be more near 25 ohms.
Thus with a 4:1 balun the load the tuner must match is 25/4 or 6.5 ohms.
Very few if any tuners will match efficiently below about 15 ohms.
You should be using a 1:1 current balun in all applications, all
configurations. The 4:1 balun should reside in the trash can.
History: 4:1 baluns became popular due to hams making folded dipoles from
TV type line or open wire line. In this configuration the resonant feed Z
is more like 200 to 300 ohms. Thus with a 4:1 balun the load to the
transmitter is in the order or 50 to 75 ohms which is great for most
transmitters with those being link coupled outputs or with the new pi
networks.
Happy New Year

If this is done then when the antenna feed Z is near 3000 ohms the tuner
will need to match 12000 ohms. Again Na Da on this approach. A 1:1 current
balun works in every case.
Still I vote for putting the 4:1 balun in the trash and putting a 1:1
current balun at the feed point.

A 1:1 current balun works only in limited cases when its impedance
is much higher than the load impedance. Given that most commercial
baluns have difficulty reaching 500 Ohms, the application is limited
to load impedances of ~50 Ohms or less.
In addition to the impedance problem, there is also a voltage handling
problem with high impedance loads.
