While I was driving in
Brisbane the other day, I had the radio on scan,
and picked up some people talking as a group, on ch 7 which is a
repeater ch, one bloke was 40kls south of
Tenterfield which would be approx 290 ks away, I couldnt help my self and called him, the
transmission was very clear.
Cheers

HI Daza,
UHF / VHF can sometimes be heard over very long distances, its caused by a condition caused "ducting" where signals get piped between layers of different tempratures in the upper atmosphere.
As an example I was in contact with a station in Yepoon QLD from
my home in
Melbourne a few weeks ago. And we regularly hear stations fom Tasmania on our 'Ham Radio" repeaters in
Melbourne.
A few months ago a Station in South Australia made a contact with a Station In New Zealand.
So given the right conditions you can have quite long range contacts on VHF and
UHF radio.

It's interesting what can happen sometimes. Maybe it's just a freaky thing.
I've had 120k on UHF but over water up the coast north of
Perth.
Also, in the good old days of analogue mobile phones I was on
the beach at
Two Rocks (north of
Perth) and rang
home (
Perth). When I got the bill it showed that I got thru via
Busselton. Directly over the water that is 240k's from my phone to the antenna at
Busselton.
Now let's talk about the range of Next G. lol.

I have my UHF antenna mounted in the middle of the roof on the Jack. Inconvenient at times especially in underground carparks etc but I get good range with it, in flat country I average around 80km over water I have had unbelievable range,
Weipa to
Karumba...
I enjoy listening to the absolute drivel that not even I can better
"looks like theres a river under the
bridge up ahead George" "better
check it out Ron".....
What I want to hear "there are 3 lots of casual skirt in front Fawlty" " rightoh mate lets dump the handbrakes &
check them out"

The ch7 repeater at Mt Glorious is one of the highest repeaters in aus let alone qld. It gets some pretty amazing range. The bloke who owns the ch7 license (a truck driver) is usually on early in the mornings with his mates before all the riff raff wake up and start their usual bollocks. the ch7 repeater has directional antennas pointed away from
ipswich because there is a lot of dribble from that way.
The most range i've managed was 22klm car to car (verified with gps) with 2x 400pro's & rfi antennas on fraser island's eastern beach. From the
home base with my 16element beam it was about 120klm without a repeater. I've been up Mt glorious and i can tell you that every single simplex channel and every cb in south east qld comes in strong :) It's very high ;)
