Using the MAIN antenna for the subreceiver switches in a -3 dB pad,
which is required to split the path to the two receivers. This results in
about a 3 dB signal attenuation in both. This may be part of what you're
hearing.

hi Jo,
you are right I can compensate for the volume loss with the filter gain on
the SUB RX. But it takes 8 dB to hear the signal in the middle...

This is about an 8 dB drop. The first 3 dB can be attributed to the
fact that main and sub are now sharing the main antenna path (the
splitter gets turned on). The other 5 dB must be due to some
combination of the other factors I listed:
1. band-pass filter alignment and losses
2. 1st mixer
Maybe this has been discussed before, if so please forgive me...
When I switch on the Sub receiver listening on the headphones, the right
channel disappears for a short instance, then comes back but with a slightly
lower volume than the left (main RX) channel. Is this intended?
I use the Sub
Hi Werner,
Use BSET to see what the sub receiver's PRE and ATTN settings are. They
are independent of the main receiver's settings. They are also saved
per-band.

hi Wayne,
thank you for your answer and suggestion but - the difference in volume is
much less than 10db. When I switch from Main to Sub the sound in my
head shifts about 10 or 20 deg to the left. With the balance potentiometer I
can correct it of course. First I thought my ears are

Hi Mike,
The synthesizer in the second RX is locked to the same TCXO reference as
the primary K3 rx.

Is there one or two local oscillators in a two receiver K3?
I have been puzzling over the stated ability of the K3 to achieve diversity
reception (single signal two independent antennas). For this to work I
believe that the subreceiver 8+ MHz local oscillator and the DDS VFO must be
in phase lock
Hi Mike,
This was asked and answered three days ago on-list, and is now on the K3 FAQ:
Q: Is it possible to phase lock the two K3 receivers?
A: They run off the same reference oscillator and are phase locked.
There is also at least one other FAQ item addressing diversity recpetion.
