Tidycat

I'm listening to a nice GMRS presentation on the 462.700 100.0 repeater here in Vegas and one participant's transmissions have the tick-tocks while all the others are free and clear. Not sure what's causing it but before every transmission with the rubber duckies had the tick-tocks.

The standard rubber duckies on these Tidradio GM-5R's have a hex set screw mashed into the threads on the radio. They were very tight and I was actually afraid I might strip out the hole getting them loose to mount the Nagoyas, so I don't think that was the problem. And both antennas were screwed down tight.

Seems odd to me too. At least the issue is resolved now. Thank you for your responses.

Haven't had a chance to venture away from the property yet but my Nagoya 771G whip antennas just came in and the interference is gone now.

Thank you sir for the helpful advice. I'll try turning the pump off which is the main power consumer here.

There's a cell tower about 450 yards from the property here. I get the knock-knock/tick-tock/heartbeat sound on both radios no matter where I go on the property so that seems like a likely source of the interference.

Greetings all. I'm new to GMRS and just got my FCC license a few days ago so this may be a dumb question... when I'm listening to other folks on any of the channels there's a repeating knock-knock sound during transmissions. Is this normal, and is there a setting that turns it off or is it a standard part of GMRS? Radio is a Tidradio GM-5R. Thank you.
