Also, this could easily be caused by one of the pins on the cable behind
the front panel not making good contact. I have seen this many times on
different Orion's and you can get almost any symptom from this.
Remove the front panel and remove all the connectors, spray them with a
good contact cleaner, then plug and unplug them several times. That has
fixed several Orion's lately.

Likely cause, filter caps need replacement. I suggest using the same
value of MFD and Voltage but go to 105 degree C rated components.
Your power up and then down and then back up and it works is the key to
the target issue.

Several times in the past few days my O2 (firmware 3.028) has had no
transmit output, and no audio output except faint background hiss, when
I first turn it on. The paddles produce a nice sidetone, but neither the
Orion's nor the antenna tuner's meter moves.
So far, at least, switching the Orion's power off and then back on has
restored operability (e.g., the tuner's meter shows forward power 115w
on 80m CW). I just checked the power supply (it's on the floor under the
desk) and found its meter showing 13v --- lower than I thought but not
likely the source of this problem. Obviously I'd rather not have to rely
on the off-on "fix." Any suggestions?
