GAS 304
We have recently put an AM set into our 4by but there seems to be no chatter anywhere on it, we used to have one years ago everybody would be on just waiting for the skip. I just cant remember what channel we used to use can anybody let me know. I don't know if it is even swared in properly.
Cheers

hey Gas
Think you will find most people use UHF not, you might find a rare person running one, but not many. We swapped over to UHF about 4 years ago, still have the AM unit sitting at
home.

Hi Gas,
I started out with an AM about 6 years ago. Only heard chat on it a few times (other than me and mates using it while 4x4ing).
They are still handy if your mates have them for the normal convoy chat, but have mostly been superceded by the clarity of UHF.
UHF has the added bonus of chatting to trucks etc etc.
AM seems to have gone the way of cassette tapes, LP's and soon to be CD's. They still work..people just dont use them.

Truckies used to use ch8. As said above not many use it anymore but if they did I would suspect it would still be on ch8.
Cheers, Trevor.

HF radio propagation conditions are terrible at the moment and I doubt if you would receive much skip on 27MHz - it's will be some months before they improve much. This is a normal event caused by the 11 year sunspot cycle.

We might be in a high spot in the low spot currently Mike - conditions have been a treat for the last few days - did a couple of skeds for VKS on the weekend plus using my mobile rig yesterday - may 3000k contacts, plus plenty in between..... such conditions have a limit of course - it can't be long now...............

Can't imagine you'd be looking for any skip on 27 MHz, 4 W and a vehicle mounted antenna.. Ground wave would be the only thing you'd be looking to achieve.

Ivan - the only reason I've still got my Uniden PC122XL in the car is that it often has a great reach from
places like central Australia. While mobile, I've had effective comms with CB'ers in
places like
Hobart and
Cairns, around noon - 1 decent HF hop to the coast, as it were - I've been camping with a bloke using the same CB that skipped to NZ, from Eyre Peninsula SA (the Tasman probably playing a part there). If I need the dash space, that radio would go - as for now, it can stay as an HF backup.

Likewise. When I had my
Ranger set in the vehicle I was chatting with a chap in
Adelaide whilst I was mobile on the Gulf Road. Also had a regular sked. with a friend in
Melbourne as I was heading south from FNQ until I got too close for him to pick up the skip. Also heard USA stations coming in but couldn't talk to them, I probably didn't have sufficient power but they would be running RF amps.
A SSB 27MHz CB could be a useful back-up in emergency but because of the sunspot stuff not much good at the moment.

Fair cop with SSB, but you're not going to be doing that sort of stuff on AM...

Been discussed a fair bit here over the years- IMO, seems that plain 27meg worth little - certainly not worth buying one - they run at 4-5 watts - the side band capable models (SSB) are worth something, in that they run on 12watts when in that mode and can have a very long reach. There are plenty of users inthe various states, jabbering away on and off during the day (CH 35- LSB etc). Again, not worth buying but maybe worth hanging onto - I have - mine is in good nick and stays in the car as a backup to the long range HF. UHF is of course great - everyone uses them. More to the point, what are your comms needs ?
