sonnenstudio Posted February 19, 2021 Report Share Posted February 19, 2021 Hi guys, I bought a pair of old Audio RMS 2000 Rx-Tx. I'm experiencing noise bursts/dropouts (see sound example) as soon as I move 3-4 meters away from the transmitter. Any ideas what might be causing this? The frequency range is 507.125/507.625 The antennas look pretty battered, do you think it would help to replace them? Thanks in advance for any tips! bests, Koen soundcloud link RMS2000 test_1.WAV Quote Link to comment Share on other sites More sharing options...
callou Posted February 19, 2021 Report Share Posted February 19, 2021 I could be wrong but this antenna looks absolutely wrong for an Audio Ltd...for any HF radio mic in fact.., So replacing might be a good idea.. Quote Link to comment Share on other sites More sharing options...
r.paterson Posted February 19, 2021 Report Share Posted February 19, 2021 Those are helical antennas and not very efficient..i would if you dont have other whip anntenas cut a couple of 7 inch bits of straight thin wire and without damaging tje sma socket poke wire into socets and do a walk.test if you are getting further than before then its prob the anntemas..those audio ltd are from the mid nineties pre diversity so getting on now so could be a off tune issue as well..there are two diff freqs make sure and try both..
