UHF training

The mob you bought it off and installed it can't help you?
It did come with a manual didn't it?

Are you after training on your specific radio or UHF use in general?

If the latter, it's not too complicated - some do's and don't and some common courtesy rules...

Don't transmit on channel 5 or 35 unless genuine emergency - similar rule for 1 thru 8 and 31 thru 38 if you see signs indicating these as emergency channels - best to avoid the duplex channels altogether unless emergency.

Ditto for Ch 22 & 23 - do not transmit - also Ch 30

Otherwise general courtesy - if a channel is used as a safety channel (say Ch 10 for the Simpson or other 4wd tracks) - limit use a far as possible to need to know and don't clutter up with needless chit chat - by all means use, however overuse could block other users.

Avoid foul language or abuse - goes without saying.

Otherwise - use common sense - my best rule is - assume you are talking to someone face to face - would you interrupt a conversation unless you have something useful to say?

Just dial Channal 40 and start talking to the truck drivers. You will learn about lots ;-)

A location would be good so we can point you in the right direction and to someone local....
