UHF Radio Thread

There was a thread here a few months ago concerning UHF radios and bike to bike comms etc. There was much discussion about what wattage was needed and that high power isn`t alway`s best, that sort of thing.

As I am belatedly thinking about doing something about this subject for the forthcoming trip "oop north" could somebody please post a link to the thread?

More power is always best, just ask Ray.

I was, saw his setup today, and as you have UHF and are coming(?) as well I thought I`d better do something about it. I can just see you two turning left and me turning right in a dream and getting hopelessly lost.

PS. Thanks Greg

We are both running the Uniden UH078SX which has a selectable power output of 0.5W/1W/5W so if we are just communicating between the bikes a lower power setting is available. I chose this model as it is rugged and waterproof and compatable with the Autocom unit I am running.

I just have to decide which bike to bring, the R1200GSA or the R100GSPD.

I have it on good authority that you should take the R100.

Hello there...

I don't know if this could help or you may have already try it, but I think "Olbis" may have the "bits" you are looking for....

Does anyone have a GME tx 4600 http://www.gme.net.au/land/transceivers/tx4600.php I am thinking of going for one of these on the bike, wire it up to an intercom system, it can be switch wired to the bike and connect to a small aerial would give better range than a handheld.

Whaddah ya reckon

It may give better range with the right antenna, however the output is still limited to 5 watts so it may not be any better than a 5 watt hand held with the same antenna.

Mounting of a UH078SX

Hi just finished mounting my UH078sx on the 640A ready to install a autocom unit to it. I has just used a old mirror base and threaded end welded the threaded end to a piece of flat bar and rivited the front part of a belt clip to it. Only time will tell if this works.

Yep I have one. Seems to work ok. I have changed the mounting position to hopefully give the radio more protection from the weather. It might be waterproof but it didn't stop water getting in it once. I had to send it back to the installer to get the water out. With having said that I think it is a good unit. However it still should have protection from direct rain. Here is a couple of picts. I've now got it mounted just above the odometer. I used to have it on the handle bars just behind the key. A disadvantage I have with my setup is, I'm worried that it will get knocked off (stolen).

That's the set-up I was going to get but a bike com' supplier talked me out of it due to earth noise etc. (but Dale reckons he can fix that) I ended up getting a hand held 5w which is now tucked in the bikes body work and set up a servo to turn on/off and volume control via a two way switch, and a coax and a antena on the back of the bike, as I only use one chanel I don't need to touch it. Oh... with recharging it's a sinch dick smith jobie in cig outlet just turn it on overnite and she's charged the next day for another adventure, it only draws under 1 amp still plenty of poke in battery to kick the donkey two years 40k klms later still happy can't see any gear but the antena, so less to worry about.

True, however with a hand held if you bin the bike and have to walk out you can take your coms with you. The Uniden comes with a spare battery and a charger base that takes the radio and spare battery so recharging is not a problem.
