K3 Sub RX stopped working on 20/17 meters

Hi
This is my first help idea. Perhaps your sub receiver is not connected
to an active antenna on 17 and 20 meters.
I have done stuff like that and pulled my hair out until I realized the
above.
luck

Re: K3 Sub RX stopped working on 20/17 meters

Well, I have a 20-meter vertical connected directly to the AUX RF input,
and a receiving loop connected to RX IN. So unless there is a setting
somewhere that somehow disconnects the antennas on 20 and 17, it's simply
not working.

Noone else has replied. I have placed a call to Elecraft support on this
one.

Thanks,

Re: K3 Sub RX stopped working on 20/17 meters

Hmmm.
Just made a new discovery.
I can get the Sub RX to work on FL2 and FL3, but not FL1 nor FL4.

Here is my filter configuration:

FILTER Main RX SUB RX
FL1 13KHz 2.7KHz
FL2 2.7 1.8
FL3 1.8 500Hz
FL4 500Hz 250
FL5 250Hz

First of, shouldn't these match for proper diversity receive? ie same
filter bw in corresponding slots?

Second, the SubRX *WORKS* again on 20m with FL2 or FL3 selected, but not
FL1 nor FL4.

Doesn't seem to matter which filter the Main RX is connected to. I tried
all the combinations for Main on CW: FL2,3,4,5 - SubRX only works on
FL2/3. Selecting FL1 or FL4 silences the Sub receiver.

Re: K3 Sub RX stopped working on 20/17 meters

Chris,

Which filters are enabled for what modes? You can check with K3 Utility.
It would simplify things a bit if you moved the SUB RX filter by one
slot (leaving FL1 empty).
Then change the filter configuration to match using either K3 Utility or
by hand in the menu.

The thing that is really important is that you enable the filters for
the intended modes.

The display of FL1-FL5 normally refers to the main RX. Use BSET to
display the filter for the subRX.

Re: K3 Sub RX stopped working on 20/17 meters

Thanks Don,

According to the K3 Utility, all four filters are enabled for Sub RX for
CW, USB and LSB modes.
However, I still can only receive on FL2/3. When FL1 or 4 are selected,
the Sub RX S-Meter goes to zero and there is no receive on any mode.
By now I am quite familiar with the BSET button ;)
