however, it drops to 48 volts and the lights in the shack noticeably

Louis,
FWIW I like my K3 noisy, almost so it sounds like there is no AGC action,
just enough to protect my ears from an unexpected loud signal. I've found
that this makes it easiest to copy extremely weak CW signals that are below
the noise, and prevents static pops from covering up the signal. T
Also be sure you don't have the NR turned on by accident. In my experience
there is not a signifiant difference in audio amplitude of a signal in CW
mode at 500Hz vs SSB mode at 500Hz when you adjust for the CW offset.

I was just tuning around 80m and noticed that my new K3 (SN 6066) seems to

I have a winkeyer USB but still just use N1MM for keying. I have not had

supported by N1MM, the winkeyer is the only approach that allows you to

Hello, I recently had the following issue and was wondering if a firmware
feature could be added to make it impossible to do what I did:
I put up a nonresonant dipole and connected it to the K3. I wanted to test
the antenna on 40m so I tuned up with the built-in antenna tuner which
obtained a 1:1
I'm wondering if anyone could advise on the best way to verify that the
K3's IF output is present and working properly. I have connected an LP-PAN
unit and I have two hypotheses about what might be wrong, one is that there
is no IF output and the other is that something is wrong with the LP-PAN.

I was using a G5RV but noticed that it performed poorly on 10 and 15m. I
switched to a nonresonant dipole of similar overall length, fed with 450
Ohm ladder line, which works noticeably better on 10 and 15m (I think this
is due to loss from the 50' of coax I had been using to feed the G5RV).

Would it be fair to assume that if the KAT3 matches a load sufficiently to

load safely for 500W?

If you want ragchew audio it probably makes sense to:
- turn the preamp off
- use slow AGC
- use as wide a passband as band conditions permit (phone) and about 800Hz
on CW
- in the receive EQ perhaps reduce band 7 and 8 a bit to remove some of the
highest pitched sounds/noise
- listen through a la
