Hello Matt and all,
In fact, I performed my first tests using only a 144 MHz SMA whip
antenna directy on my KX3 and it was not a good idea at all (high SWR,
too close from KX3?)! Today, I put my KX3 +2m on a dummy load and it
was far better this way but I still have birdies especially near
144.300 and 385 (not checked else where yet) and as my main interest
is weak signal this is not good for me. I found that power was only 2
Watts using my Bird 43 and 5W / 100 to 250 MHz slug; it is a bit low.
I managed to make a QSO with a guy about 40km away using a 3 el. Beam
on my balcony (good location here close to the Atlantic ocean) ,
starting with my IC-910H and then switching to KX2+2m. I got good
audio quality report in SSB. S-meter indication was low (about S9
compared to 9+&( on my IC-910H without amplifier. I put Preamp in
service but may be I could put some extra gain in the RX chain. KX3 is
"leaking a bit" as I could hear it on my IC-910H; useful in order to
put both transceiver on the same frequency ;-)
Tomorrow I will leave my vacation house in SW of France and move to
Paris for a few months there so I need to stop my tests on KX3 + 2m
for the moment. May be I will use it in Paris with a more decent
antenna that whip I used first (in fact I would need a ground plane
attached to KX3). I am affraid I will not manage to use KX3+2m the way
I did long time ago with my IC-202 and internal whip antenna!?
Any commentary or experience?

The description below is a little vague, so hard to really comment.
- birdies: do you observe these with no antenna connected to the 2m
SMA socket? On which frequencies? Is it consistent?
- instabilities: what exactly do you observe when you encounter one
of these "instabilities"?
- microphone effects: I guess you probably don't mean microphonics.
Maybe you mean some sort of RF pick by the microphone? Do you observe
"microphone effects" when transmitting into a dummy load?

Hello Elecrafters!
I am not too happy with a 2m module I have just installed on my KX3:
lot of birdies, instabilities, microphone effects.
Any idea? Thanks in anticipation, 73's.
