They've allowed others to encroach on it for 30-odd years and with numbers of CB users ever dwindling I can't see there being an en-masse revolt to reclaim it.
When I tuned in I did just that - no transmitting, plus I wasn't sure how well or even if the twig was SWR'd in. It was interesting to listen in to and good to hear it was still well in use.

Re: CB'ing and Ham radio in the 21st Century
You do know a who the primary user is? I'm not sure that any cb'er would argue against the MOD..

Not at all but how often is anyone in court for using the bandwidths unlawfully? I'm sure there some cases where action is taken but just like that law about recording a phone call without the other side's consent I doubt many people are put off by it plus I'm sure that in all but the most serious and disruptive cases (if there are any/many) I doubt many resources are allocated to prosecutions by the authorities.

Re: CB'ing and Ham radio in the 21st Century
Its actually quite common for broadcast and business bands and has happened recently for cb bands but mainly by causing problems to other licenced users. If the MOD decided to use 27mhz then Ofcom would have no choice but to start policing the band. Just because they've been lax for the last 20 years doesn't mean that it'll continue foraanother 20 especially as unused bandwidth is getting mores and more scarce.. They even started grabbing back some ham radio bandwidth this year.

Re: CB'ing and Ham radio in the 21st Century
No it's true we don't know what will happen in the future, I'm just going on what has (or rather, hasn't) happened in the past. Thing is there are so few 27 users these days you have to wonder how much effort would be put in to tracking people down. Clearly the administration and process of issuing CB licences outweighed the cost of producing them.
To be honest I'm surprised the band has lasted so long for public use. When this thread started I was surprised to hear it was still available to us.

Re: CB'ing and Ham radio in the 21st Century
Such is the world of mobile phones, internet... Etc...
PMR 446 also reduced the amount of cb users..

No your right...... If the conditions are right you can talk around the world on 1 watt!!

Re: CB'ing and Ham radio in the 21st Century
How would you go about setting one of these up. I have one back in Newcastle from my passed grandfather. The antenna is still up (12ft looking at it) the Cobra unit which I think I've posted in here before, huge Mic block, then there's loads of separate devices with dials and switches on them as well as some plain ones that look like power bricks. Next time I'm up there I can snap some pictures of it.

Re: CB'ing and Ham radio in the 21st Century
Do any of the devices say SWR on them?

Yeah, has a meter on it, the others have faded writing but one says Power supply, manufacturer, Altai. From the top of my head the main bit is the Cobra 148 GTL?

Re: CB'ing and Ham radio in the 21st Century
Ok the power supply is important obviously! I used to have an old Altai, they were really popular back in the day.
Broadly speaking the SWR meter will make sure the antenna is tuned as correctly as possible, this is a good guide.
If the mic you use has a 'power' knob on it make sure it's not up high - usually around 6 or 7 (if it's numbered) is normally about right.
Do any of the devices have what looks like a heat-sync on top?

Think you mean "Heat sink" for the uninitiated a finned piece of black metal.

Re: CB'ing and Ham radio in the 21st Century
I'm sitting looking at a Kenwood TS-480 that hardly ever turned on. It's connected to a multiband sandpiper short vertical and a sloping half size G5RV. I sold my TM-D700 V/UHF dual bander last year to raise money to buy my (pedal)trike.
I just got a bit fed up of the "rubber stamp" QSO. Name, QTH, Signal, Age, Weather etc.
I've done Voice, PSK, SSTV and a few other modes. The most I do now is a very occasion bit of WSPR.
I've seen mobile phones and the internet kill radio, both CB and HAM. When I was a member of a local repeater group, the members would text each other to say they were on their way.....and then repeater (non)utilisation would be a topic discussed at the meeting.
Hobby radio is given more recognition in the states and probably in other countries as well. When I suggested to an Emergency Planning Officer about HAM radio, his response was that any references to it were pretty much erased from most LA's emergency plans.
