Sennheiser g2 evolution problem

I've had my g2 wireless lav kit for a couple years now. I dont use it extensively and i've always been satisfied with what its used for...which is mainly sit down interview type things. When i first got it the range was extremely good without getting drop outs or static and the 150 metres (490 ft) seemed about right when i tested it. However now it doesnt take much distance for it to start having static. not a prob for sit down interviews but will be a prob in other circumstances. The sheathing or coating (whatever u call it) on mic wire at the base near where the 1/8 mini jack plugs into had started to become exposed so I wrapped it with electric tape. Would that affect the range though? I'd think its some kind of radio signal problem. I can always get a new ME-2 mic for it but would want to know the source of the problem before wasting $. Any help would be appreciated.
 
A lot has changed in a couple years. The C band has been eaten up recently, but you should still have decent results. You should definitely try changing frequencies if you haven't already. Bad batteries have given me issues in the past. For something that doesn't get used often, I don't think you should have any major issues. Might be worth a call to Sennheiser if you can't troubleshoot it.
 
Worn insulation might indicate mechanical stress. Try jiggling the mic cable at the connector and see if that triggers the "static" you're hearing. You could have wear and tear creating a noisy joint inside the connector plug.
 
Thanks fellas. Yeh Steve a wiggled and jiggled and tugged lol...and it didn't cause static. But when i (or my subject) walked out of "range" it started to fry occasionally. then walking out further it would get progressively worse. As i said though this is weeeell within range of when I tested it new. I will try the other suggestions by you guys though.
 
I assume you have checked for open frequencies new DTV transmitters operating your region.
If one of the antennas is 'kinked, that could be possible break.
Make sure the transmitter's antenna is not touching the wearers skin or in very close proximity to a mixer, electronics, cell phones or metal objects.
Can you post a clip?.. different types of interference or a compromised cable normally make distinctive sounds, which many of us experienced users can ID.
 
thanks Rick...more trouble shooting options is better. ok kool.... I'll post a clip when i get the chance. than
 
If it's distance related then we can discount the mic wiring. what does the RF meter say? Full strength or weak. Ideally you need to try substitution of one component to move forward. Do you or maybe a friend have a UHF scanner? Dialling in the frequency and selecting wide band should let you hear the transmitter - so you can determine if the poor range is a TX or an RX problem. If with a pair of headphones in, you can hear the transmitter loud and clear when the proper receiver can't then it could be faulty. If on the other hand, the scanner can't hear the transmitter either - there lays the problem. Borrowing another transmitter would allow the same test. Without the extra item, you really can't tell which of your two items is faulty. Find a friend - quick!
 
My first guess is Rick's thought. Antenna issue. Though I haven't seen yours, I would hazard a guess its on the transmitter side. That's usually the unit that sees the most abuse from talent. Sitting on them, stressing the connections, tweaking the antenna, etc.....
