Many thanks, Jordan & Mark.
In response to Jordan:
1. The freq range: 782-806 mhz
2. No, I think i did not any search at all.
3. The only setting in the transmitter resembling squelch is called “RF out”, which settigs are H (30mw, for long distance function) and L (5mw, for multiple channels)
In response to Mark:
I’ll make the test you suggest. The quality of the mic is a possiblity i’m considering, since the wireless system i’m using is low cost.
Thanks again.
