Fw: K3 sub receiver no signals

Also check the external cable to the radio. When I replaced my FT1000 with a
K3 (best move in the ham shack ever ... but I gotta say the FT1000 served me
well for 20 years), the the short section of cable from the external rx
antenna switch box to the K3 went bad. I took the K3 apart first thinking I
did not plug something in or an internal cable was not correctly seated.

I saw that someone else suggested checking all the cabling. Good idea.
Also, press the "A>B" switch twice quickly (should see "A>B ALL" in VFO
B window) to make sure both main and sub are on same freq, filters etc.

Oh, yeah, lyou DID turn ON the Sub-rec'ver. Didn't you?

Let's see, check internal cabling, Antenna, settings. Oh, how is your
RF/AF gain controls set up. I have separate RF gains, but the AF gains
are set up so that the little knob is volume, and the larger one is a
fader. How are your set up?

K3 sub receiver no signals solved!

There was a config error in the Sub filter setup. I have a 2.7 filter
in slot 2 and 400 in slot 4. Those were setup correctly. The Sub also
thought I had a 2.7 in FL1. Changed that and the receiver came to life.

Obviously the other issue was that I had decided, for reasons still
unknown to me today, to install the input using the AUX BNC.

Thanks for the suggestions and hints!

We are fortunate to have some very smart helpful folks on the reflector!
