Hi all,hope someone can help with this one.recently installed cb setup,cb powers up,tx rx lights work when mike keyed channel change works,but cannot get any swr readings at all.double checked all connections, nothing but skip on all 40, ant. is centre load 24" mini mag have also tried 48"modulator ant with mag mount both direct to roof so should be good ground plane.cannot understand why no swr readings whatsoever.hopefully someone will!

is the meter not broken? If you wobble it, can you see the needle move?
Are you sure you are transmitting? Never mind the lights, someone confirmed they can hear you? Might have popped the tx

thanks for quick reply lads.meter is K-PO new from truck king and needle does move when meter wobbled so not stuck.wired as per instructions for ant. and cb.swapped around just in case wrong but still no swr reading.meter could be faulty i suppose but who knows. have emailed truck king, awaiting reply but one of those chicken and egg things i dont know if faulty and normally suppliers wont admit fault,we shall see! just thought it might be something down to me but keep those suggestions coming.thanks

I had the same issue - make sure, if the radio is a 'European model' that you've got it switched to the UK frequencies - I hadn't Embarassed

And it's on AM or FM or whatever it's supposed to be Embarassed

have you got the top slide switch on FWD and the bottom one on PWR? Have you got your CB on a UK FM or Euro channel as e.g. a French AM channel probably wouldn't register anything either?

the rig is a danita 240,. fm only.presume uk, has quality tested stamp in english on back. meter has calibration knob and fwd / ref switch.cannot seem to recieve anything,just loads of skip and no reply to anything out going.all this has got me going!!

just found out there are two approved uk frequencies. C.E.P.T. 26.965-27.405 and U.K. 27-81,the former is E.U.band,but both for uk use. looks like the rig i have is not in popular use here and the reason i can get no swr is antenna is not compatable with this rigs frequency,what do you guys think? i am lost!!

Return the unit for a refund if you can and get one that you can work with? Sorry, not much of an answer, I know ...

thanks for comments guys,tried with set up again today and on channel 26 picked up faint foreign chat! could be foreign truckers on nearby dual carraigeway?anyway still not much use.might as well forget trying for refund as would have to pay return shipping and if they say not faulty have to pay to get back.will get on to truck king again as no reply to my answer of what cb i have.i will have to find someone local with swr meter to try process of elimination,then i will know for sure.

I would stop trying until you have a known good swr meter. If you have a short / open circuit in your coax, you'll be putting your transmitter through a world of pain.

Not sure if 27MHz will do it (I do not think so) but if you key a VHF radio next to a fluorescent bulb, it'll ignite. Was a "party trick" way to see if your radio is working.

Tried reconnecting setup today and i have swr.....got nice low readings after playing with antenna.dont know what happened,did nothing different than before!! still no tx/rx,though.i think its because of these two different wavebands in uk i spoke about before and i have got set with the waveband no one uses.dont know what else to think...perhaps wave the white flag on this one!
