Odd radio issue
My HK factory radio sound great when the main power switch is set to Aux, but when I turn it to run, the radio looses signal . I checked the wireing and it looks fine. Dealership had no idea. I checked the power antenna and it got its power from the cigar lighter, which is normal. Not sure where to go now. I am that thinking a power drain when turned to run position is the problem, but no ideas how to proceed. I plan on hooking my charger to the bike and see if the problem persists. Could it be my battery getting weak?
I had posted about this before and thought I had it fixed. Now it is doing it again.

2013 rg. Everything stock except for a hidden antenna under the fairing. It gets its power from the cigar lighter just like it should. When switched to run, it sounds like the antenna has been pulled. Radio is still on, volume works, just cannot get any reception.

Sounds to me you have a gremlin giving your cig lighter VD (voltage drop) in the run position.To start with I would check your power lead and ground to the antenna.If you have to for testing purposes run the power and ground from the antenna to the battery and see if you get the Same results and work backwards from there

Why didn't I think of that? Thanks I'll see about digging into it this weekend as it is supposed to be raining anyhow. I did take the fairing off and check all the connections After moving things around following wires it seemed to work, but then went back to it's old habits the next day. I may just splice in the power to the wires, and avoid the blade connectors at the cig lighter plug.

Sounds like you're getting close.

Test 3 sources (Radio, Ipod/phone on aux, CD in player). If only the radio doesn't put out sound to the speakers it's either the tuner of the radio or the antenna. If the antenna cable is coax, sometimes the copper core gets brittle and snaps within the insulation, leaving you with two ends butted together. If you have a multimeter test the antenna cable for resistance.

If you have your stock antenna cable, set your multimeter at the lowest resistance setting, probably 200ohms. Meter the original, and remember or better yet write down the reading. Then disconnect your in-fairing antenna and meter at both ends. The readings on both should be similar. If the in fairing antenna has a higher reading it's probably shorted. Then it would be time to get one from Biketronics with a lifetime warranty.
