[Elecraft] Simultaneously listening to 2m and 6m

We seem to experience what appears as a software anomaly when trying to
listen to 2m on the Main VFO and 6 m on the Sub. 

Our club station has a K3 with a sub-rx, a K144XV interal 2 m option and an
extermal XV432. A 6 m antenna is connected to Ant2, and HF-antenna to Ant1.
The 2m option works fine by itself, as well as HF/6m.

When we set it up to listen to a 6 m beacon on the Sub-rx and switch bands
through HF/6m/2m/70 cm on the Main rx, then sometimes all works fine. Other
times the input signal seems to disconnect from the 6 m sub rx when we come
to 2 meters on the main rx, all other combinations are fine (HF/6m/70 cm on
the main). We try to use Bset and switch Ant1/Ant2 on the sub, but it does
not help, neither does holding RX ant for antenna switching.

It is a problem which is kind of hard to reproduce, but it appears often
enough to be annoying. So far we cannot predict what combinations of
settings that cause this. But I wonder if others have experienced anything
similar?
