I am going slightly crazy here... I have less than 100m range, with my licensed radios and midland pmrs. But not always. Sometimes it's maybe 200 metres, sometimes there is nothing AT ALL getting through.

They'd not hear me because the CTCSS tone would be missing = but you can bet I would be stronger than the low power radio inside the leathers of the instructor. It would be a very simple process to wreck what you are doing.

What antennas are you using & are they in the clear or against the bodies of the riders?
If you have a small antenna inside a jacket & with a human body between you & that radio. I would say 100 yards is not bad at all for UHF.
There is a good reason why dispatch riders & the old police radios are worn the shoulders with the antennas in the clear.

Incidentally, the manager of the previously mentioned school did mention (as if it was completely normal and ok) that he has heard me on the radio (I've never heard him!!). This person has made it his mission to 'catch out' other schools/instructors - whenever he deigns to talk to any of us direct (VERY rare) he opens his radio so that whoever is back at the base (or wherever) can listen to the exchange...
Anyway, enough with the paranoia... There are some things I can try, thank you for your input. I will try having the students wear the radios in belt-bags to remove the 'body-between' situation, and the bike mounted antenna for my own radio.
