Aaren,
Regarding RF ingress, I have had a few intermittent problems with my Flex
5K, most notably on 20 meters. Over the years, I've had similar problems
with other rigs (it's not just Flex). Aside from having an earth ground
right in my basement shack and grounding all computers, radio boxes
I know this has been shared before, but it is worth re-posting.

After reading about common mode currents, I order about 100 of each (mix 31
and mix 43) chokes. I have them on just about everything as it relates to
RF.
Every n
RFI can occur when there is an impedance mismatch betweeen the
transceiver and the antenna. Coax acts like it's actually three
conductorsthe center, inter shield and outer shield. Ofter, RF
voltage feedback travels into the transceiver on the outer shield.
Straight out of the ARRL handbook.
I have the same issue. Works on 80 and audio is distorted on 20 meters. I'll
bet it is RF ingress issues like mine. Now to determine where the RF is coming
into the radio.

A simple line isolator saved my flex-3k from the trash heap. I thought I
was going crazy and that I wasted my money. Turns out it was just a little
RF getting back where it doesnt belong. Going through this helped me
realize that some things in my shack needs to be reworked. I'm sure alot of

With respect to your mic situation, did you check the proper box on the
input to make sure that you have the front panel mic turned on? You can
select either the front or rear mic input from the menu.

The "it works on 80, dies on 20" very much sounds like RF getting into the
computer. Others can give you a list of things to check, but to start with
- you need a short solid ground connection between the 5000 and the PC. RF
in the shack may result from high swr, keeping RF off of the o

Sounds strange as their quality control is pretty great. I am also
confident that Flex will get on the phone with you and sort it out.
Just to make sure that RF isn't an issue, do you have a dummy load that you
can test 20M on? Usually if a computer up and freezes, it is due to RF
getting

1. Front mic port is DOA right out of the box.
Check to make sure that the notch on the mic connector is lined up
correctly with the port when you plug it in. I've noticed that some
connectors go in without the notch being aligned.
