UHF Radios for the trip
« on: March 12, 2014, 10:44:14 AM »
We had a guest speaker at our 4wd club meeting last night by a uhf guru from Electric Bug here in Adelaide.

In his talk he was saying that 80ch and 40ch uhf's don't really talk to eachother that well. 

Since that it will be law that you're not supposed to use 40ch after 2016, there is no time like to present to upgrade should to an 80ch so we will all be on the same frequency.  Also we may use one of the higher general use channels for the trip due to the fact there may be less traffic on it eg: ch65.

Below is a list of what the different channels are used for too just for reference:

Good advice, however a mate has a 40 and we have an 80 and have no problems chatting.  Not sure if that is just good luck though.

Good luck to the lawmakers from stopping people using channel 40 in 2016.

We have no trouble talking to 80channel type units from our 40channel vehicle radio. Obviously if the 80ch unit is on channel 41 or above the 40ch unit wont work to it. We have an 80ch hand held for recoveries etc and there's problems talking to the 4wd's 40ch unit.

Cheers

Some of the more recent GME units can be upgraded to 80 channel from what I have been told. Might be worth a check with them

While this might help for chat between your group it wont help in hearing if someone is coming up the other side of the same dune. Definately worth scanning all channels for other groups to avoid dune top collisions. I think ch10 is the recommended channel.

I only have a 40ch and have had no problems with others on 80ch yet.

cheers,
Steve

Don't think we are going into dune country - except for the Chambers Pillar run -- M

It is a volume issue. Some 80 channel units will compensate so you won't notice.

I'll be keeping my 40 channel for a while. Too expensive to upgrade when I only use a few channels anyway. All of which are found on a 40 channel unit.
Plus I only just bought a new microphone for it :)

Problem is the 40s are transmitting across double the bandwidth to the 80s, so you are cutting off some of the signal
