For anyone that does have experience with chinesium radios..
On one private range I get a Wouxun 70Mhz radio to use for safety purposes.
But pushing the PTT or tangent usually causes loud buzzing sound at the recipient.
I have tested that the fault happens without my headset and microphone. Just the radio, Peltor PTT and Peltor headset wires & splitter are enough. The fault can happen on PTT alone, but is nearly impossible to recreate / recreates very rarely. Connecting the rest of the wire makes it very likely to reoccur.
Without the wires or headset connected, the radio works fine by itself.
The problem itself manifests by the wire being very sensitive to pressure under hot mic depending on how the cables and radio are laid out.
Yesterday I had the whole unit on the floor and just bringing a torque wrench nearby the radio antenna with hot mic was enough to cause it to buzz.
If I take the antenna out of the wouxun, it works without problems with the rest of the wire and TX goes through.
I figured it is the antenna but I have another wouxun that has longer antenna that should be also better quality and it behaves the same.
I think the wouxuns maybe have a problem with signal / grounding? Too bad I have not been able to yet test any PMRs on this rather new setup yet since I only own 1 radio myself. In few weeks I will be able to test PMR radio with multiple receivers.
Or maybe the fault is in Peltor wires/devices not being protected enough? I have measured all the wires and PTT to be good to go.
And I regret having to bring problems made in china over here but I ain't going to buy them new radios to solve this problem and this also intrigues me since on their own their radios do work well. Maybe there is another lesson to be learned here.
I was given 2 wouxons to test this problem so if you have any suggestions to test, I am open to it.
