CB radio's

[blackolive (Ste)]

a number of "multi standard" modern radios have been approved that can be used over this freqency range.

Whilst its perfectly legal to purchase them and use them on receive over the full frequency range, without an Amateur radio licence it is only legal to use them on transmit on the approved CB channels

 

[Kayos]

Is that band just receive or can it transmit that far out of band too?

If it can transmit too, I can't see how it got approval, unless it's been 'illegally' modified since...

It’s an export radio, being a licensed amateur I can use it on 10 and 12m, alltho only within the conditions of said license

 

[Kayos]

So technically it's not legal for use on cb frequencies, whatever licence you hold...

No, you can reduce power but it’s not type approved.

I had a mobile whip (DV27?) mounted on a metal bread tray with wire radials on a galvanised shed roof, seemed to work OK for me.

Holy thread resurrection scanning some old pics and found one of my "homebase" CB antenna from the late 70's.

still got my superstar 2000 and a few others by all accounts SSB is now legal

going to 40 channel fm mobile phones and internet killed the cb radio

You start with a DV 27, move up to the DX 27 then get the Firestik

That ones a dx 27, they are a helically wound 5/8 wave. This is the dv27 complete with biscuit tin, modulator, and 7ft firestik.

That takes me back to my mid teens.
Biscuit tin and an old car antenna.

DV27 wasn.t it

The original DX27’s as already mentioned were 5/8 wave rather than the DV27 1/4 wave. They are fully wound with a very short timing whip rather than the top loaded dv. With the correct weather conditions and only the legal 4watts it was sometimes possible to make contacts up to 40 miles with a DX27, well that was the best I managed

Happy days back then.
