I changed our GNS430 to 833 a while ago. Everything seemed fine, then recently trying to talk to Duxford (122.080) I found I could transmit to them but couldn't receive. Since then I've had to switch to box2.
I thought this was a problem with Duxford as every other station I spoke to was fine, then the same thing happened with Lydd.
Reverting to the old Duxford frequency 122.075 works fine on tx and rx. I understand (there's some very good threads on this forum) that the transmit frequency doesn't change between 25 and 833, but the receiver bandwidth is reduced on receive. So it seems my GNS430 has a problem with centre frequency on receive in some cases.
For now I'm reverting to the old frequency.
Has anyone else has this problem?
