So today I turned on my TRX-1 (using an AC adapter as I usually do) and it seemed unusually quite. I powered it off, unplugged it, and turned it back on using batteries and it was locking on freqs. For ex. I hit the WX button on AC power and it would not lock onto a channel and just kept scanning but doing the same on batteries it locks on with no problem. This was all done with the scanner placed in the same position on my end table were it usually sits. I also tried it in a different room and get the same results. Anyone run into this issue before?
