Re: CB radio - SWR problems
 

Sorry to butt in guys, I just want to say that this is a fantastic thread!

I've barely understood more than about 3 words but it's great fun to read nonetheless :D

That's a big 10-4 good buddy!

So it's 10-10 'til we do it again!

:D

Would now be an appropriate time for me to post this?

No

In 10 years, I don't think I ever said 10-4. :dozey:

Roger...

Its woirth testing the SWR meter against another one, as you would hate yourself if it was just a faulty metre its hapened to me a few times..

Cor I didnt even realise CB's were still going am tempted to get mine out of the loft now.

Jeez guys, this takes me back a bit. :D
Will have to see if my stuff still works, used to be a dab hand at tracking down wave-hogs with my trusty old DV27 on my car.
Does anybody still use AM by the way?

we will have to have a roll call of handles

mine were Sid Snot and Big Sid and used to help run the BTB CB club 20 years ago.

Re: CB radio - SWR problems
 

Being a huge "Convoy fan", I have always fancied getting into CB radios. Seems a bit more to it than I first thought :erm:

Re: CB radio - SWR problems
 

Eee, this brings back memories.... old ones but good ones.

I still got some of my gear packed in the loft, are people still using the hi/mid/lo bands, I thought they had all changed to UHF now?

What's the chatter like thse days? I left it when it got to just stupid kids playing music all day, swearing etc. Couldn't get a decent conversation in at all. Oh & I got another license...lol

Ther's nowt wrong with a Thunderpole, damn good aerial.

Yes but ugly....

Re: CB radio - SWR problems
 

dont forget that the SWR will only be great at the middle of the freq range that the ant is designed for.

just my tuppenny's worth, but it might be worth checking at a different freq?

Re: CB radio - SWR problems
 

Yeah we tried it on super-lo and super-hi (2:8 on both) and the 2:3 is channel 20 on the mid-band.

Re: CB radio - SWR problems
 

First thing is where have you measeured the SWR?
Swcond thing is NEVER tune the rings until you know what the SWR is.

The best way to check the SWR is to connect (f Possible) the swr to the antenna directly or as short s patch lead as possible.

The reading at the radio ens will be different...its what is at the antenna that counts.
Is it possible to ground the radio in the house?

If there is and SWR on the cable then it will read differently on a different lenght...its a wave after all.
If all else fails...stich a tuner / matcher in line to flatline the swr to the radio / finals see a good match :)

Re: CB radio - SWR problems
 

We measured the SWR at the antenna end of the coax. We only touched the rings after we couldn't think of anything else.

We've thought of using a matcher but as he's hoping to use the set-up for DXing, he doesn't really want to lose power.

Dare I suggest removing the twig from the roof & trying it elsewhere temporarily.
