Unless I'm mistaken, I AM being forced to pay for an ATU option in

thrilled about this part of

ANT1 - transmit antenna
KXV3 - rx antenna to main rx
ANT2 SO239 (no KAT3) - rx antenna to sub rx
Can someone please confirm this will be doable from the outset of K3 production?
Steve - I believe the answer to your question, "Can the Heil GM-4 work

the GM microphones have a capacitor that isolates the 5V from the GM

If memory serves, that antenna is a variant of the T2FD and should have

I have it working now, thanks for the helpful suggestions. I don't
know why it's suddenly working, I didn't change anything. I'll keep
an eye on it.

Thanks for posting this Roy. Not one mention of the loud relay in 31
eHam reviews and it's something that obviously would bother some of us
(me) more than others.

Is there an acceptable range of headphone impedance for the K3/K3s?
I've got some 300-ohm headphones and wondering if the impedance alone
makes them a poor choice for my K3s?
Thanks & 73,

Thanks for all the public and private responses! My 300-ohm
headphones should not be a problem for the K3s.

I believe this also means that the K3 headphone output circuit will
deliver 10X power (with fixed V, P~1/R) into a 30-ohm headphone as a
300-ohm headphone, so at some point the amp might clip as you raise
the headphone impedance?

give them a thumbs up if you need an isolating type
headphone, although I prefer the higher priced Beyer DT770M. If you
don't need the isolation, I prefer the more comfortable and better
sounding circumaural open-back Sennheisers.

dphone impedance
and efficiency that makes up for the inverse relationship between
output power and load impedance. I just don't observe this efficiency
rule consistently in my collection of headphones with varying
impedance. Headphone efficiency clearly has other dependencies than
impedance.
