I have the G50 wireless system withe the tbp12 transmitter. The transmitter is emitting a very annoying 30 hertz or so buzz or ray gun sound. If I wrap my finger around the transmitter's antenna it goes away completely, This is not acceptable in a live setting. I am using the power supply provided with the system. The sound is there no matter the venue. I've completely troubleshooted all cables,guitars and amp and have verified it all with the wireless system. Batteries in transmitter are new as well. Transmitter firmware 1.04 Please help. Thanks in advance.
Relay G50 Wireless Very Annoying Noise

OK coryk, does this...
...I've completely troubleshooted all cables...
...include whatever adapter cable/s you use from your source TO the TA4 input of your beltpack ?
That question arises because your reporting...
...If I wrap my finger around the transmitter's antenna it goes away completely...
...makes me think it very likely that what you're hearing is largely RF "garbage" that's "leaking" into the signal path via improper shielding of your beltpack's analog input stage.
While that's most likely to be caused by its input cabling, it's also not out of the question for it to have arisen from a hardware "breakage" or other failure inside the TBP12 itself, ...which would then require its surrender for servicing.

Ron, it's been used in a live setting probably a dozen times totaling about six hours use since new. I'm using the cable that was supplied when new...
So, coryk, ...I'm guessing the unit started out OK, but has just developed this problem, ...which would REALLY make me suspect a "dry" soldered joint (or something similar) that's "come unstuck" somewhere, one that's much more likely to be in the cable, although it could be in the beltpack itself.
(This is neither reflection on your care and handling of the gear, nor on the generally high quality of the goods as supplied, but we know that a minuscule percentage of those produced will inevitably only show faults like this after a period of "real world" service.)
Rather than being forced to wait for the warranty procedure, it would be great if you could drop into your local Line 6 outlet to try another adapter cable, or (even better) take your whole kit to the store who supplied it, so an instant "swap" could be done to get you "back on the road" as fast as possible.

So maybe it is inside the beltpack, after all, coryk...
Nonetheless trying another cable and/or a visit to the dealer would still remain the best course of action, as the almost (but not quite) "cellphone-like" noise that you report is pretty much how I'd describe the sound of our beltpack's data stream "leaking" into its own analog input.

I should also add that I regularly experience a huge variety of noises whenever my TBP12 input adapter cables are unterminated, (not connected to their sources, be they XL or the output jacks of instruments) but that the "racket" so generated invariably disappears when proper connection is made.
(My inventory contains eight TBP12 beltpacks.)
