Damage to SMT version bitx40 from nearby transmitter 17 messages
How likely is this to happen? Bitx40 connected to 40M resonant antenna perpendicular to another antenna with a 100W transceiver running a Winlink gateway.
I fully expect front-end overload and nasty n

Is there anyone in Maine, USA that would be interested in a couple unassembled BITX40s? I have two kits. I was about to assemble but have decided not to. I'll make a local person a really good deal. D

bitx v3 rx linearity? 5 messages
hi! I'm poking at my ubitx 3.0. It hasn't behaved well at all on either transmit or receive. It turns out it was very not calibrated and balanced for transmit, so I've fixed that. However, receive is
