I recently got a Yaesu VX-6 in high hopes it would be able to work on summits
even when commercial radio transmitters are near (common situation).
But I was very disappointed to see it actually performs worse than my previous
HT (Wouxun UV6D).
With Wouxun, it’s squelch would stay open regardless of level (say SQL 9) and I would
constantly hear noise, but when someone called, it was usually able to pick up the FM
and I was able to hear the caller clearly.
The Yaesu becomes as deaf as a brick on 2m and the squelch will not open even
when it’s set to 1. There were at least 5 stations calling me and I wasn’t able to
hear a single one! When I set squelch to 0, I was able to hear the noise but no
stations, it simply would not decode any FM.
Finally, I turned on the front end attenuator (menu) and I was able to pick up some
nearby stations. They were much weaker (as expected), S1 to S5 on the meter
(where they would normally be S9+, but at least I was able to hear them and they
would open my squelch).
Does anyone have similar experience? I got the Yeasu because I had heard all the
praises about it’s resilience, but this is rather sad. I’ve had it for several weeks now and
it works perfectly when transmitter towers are not near.
Could the reason be that the transmitter (commercial VHF) could be messing with my
radio’s intermediate stage?
