K3S Sub Receiver stopped working

Hi All,
I need some suggestions on where to start trouble shooting. I looked at
Nabble and I have checked all that is listed there and no luck.

The sub receiver was working perfectly. I took the radio apart to add some
new filters to the sub receiver. It originally had two of them; configured
as 2.8Khz, then a 400Hz right next to it, and then 3 blank slots. I
removed the 400Hz, the the filters are in the following order; 2.8Khz,
blank slot, 1.0Hz, 400Hz, and finally 250Hz in the 5th slot.

I used the K3 utility to configure them, with the appropriate settings for
each filter.

When using the radio, I have both the main and sub receiver on the Main
antenna. If I tune to a strong signal on the band, using just the main
receiver, I hear on both sides of the headphones. When I engage the sub
receiver, I still hear the signal in the left ear, but the right ear goes
to just white noise.

When the sub receiver is engaged, I can hear sounds in the left ear when
pushing any buttons on the radio.

I am somewhat stumped, as I was very diligent in disassembly and then
re-assembling it. Using most current firmware, 5.66.

Please advise.

Re: K3S Sub Receiver stopped working

This is probably a "101" level thing check, but can you confirm that the
sub-RX setting of "MAIN" has stuck? It's happened to me several times in the
past that it's changed to AUX seemingly on its own.

I thought I had killed my Sub-RX just a couple of weeks ago and this was
indeed the case.

Re: K3S Sub Receiver stopped working

Since when can there be no empty slots between filters?

Re: K3S Sub Receiver stopped working

I thought I remembered seeing that in the instructions. If I was wrong,
my apologies.

Re: K3S Sub Receiver stopped working

In reply to this post by KE8G-2

I often find the second receiver switching to ANT 2, which on my K3 is a dummy load. Easy to diagnose and fix using BSET, but a bit annoying.
