Dean's example is still valid. By placing the CM Choke at the "wrong"
distance of 20 feet from the tuner, the 3,000 ohm Z presented at the balun

Hi,
I am about to enable remote on/off on my K3 and I just noticed in the manual

supposed to pull the line to ground until you wish to power off.

Yes, fuse it. I have repaired several KX1s that were damaged by

I would suggest a fuse in the range if 2 to 5 amps. 3 amps should be

Although I agree comments from Elecraft engineering would be welcome,

The KX3 is direct-conversion from RF to baseband audio. Therefore, I

Technically true, Terry. I perhaps oversimplified my response to the

However, the answer to the question remains correct. - "No, you cannot

No, the KX3 roofing filter module is completely different. It works at
"baseband" frequencies, rather than the 8+ MHz IF that the K3 uses. You will
not be able to use K3 filters in the KX3.
