The signal strength has not changed since the original post maybe a % or 2 from last week to today the weather is really crappy and over cast today here in Lancaster NY. I let it on the 103 S for a few minutes it's set on transponder 1 same with the 99 s I changed it to transponder 21 and let it sit and it popped up with 97% for both tuners on the one h24 receiver. so what gives? I back out and go back in and it's back to transponder 1 again and signal not acquired why doesn't it stay where I put it last? and does this effect the other channels I'm having issues with or is it a separate issue? the 99 S only lets me change between transponder 1 and 2 that's in and not acquired on both of them. so If on a different transponder for the 103 S I get a strong signal it's not an aim issue? Thank you for you help!
