Did all the fitting etc ect and came to do the swr.

At this point I was feeling chuffed it had all gone to plan. Silly me, as it
all went pear shaped at this point.

Went to channel 1 UK, swr HUGE
Went to channel 40 UK, SWR HUGE.

So I checked my aerial was earthed and went through connections etc. Tested
again....

and I don't know what happened but nothing showing on the SWR meter, not to
set or anything. CB isn't showing anything on the dial when I transmit
either.

So probably caused by the huge SWR either the meter, or CB or both has gone
bang.

Bloody magic. Of course now I'll need to either get a new swr to work out
its the CB that went bang of get the CB repaired etc and if I do all this
I'll still have the problem that the SWR is HUGE and so by testing the CB
I'll blow something somewhere.

Ah bejesus,

Dave

How about TXing into a dummy load with your SWR meter in line to see if you
still have output? Iv seen CB dummy loads that are just PL259's with a
lightbulb in the end are very cheap and a good tool for the shack.

sounds to me that you have a fault in the patch lead between the cb and swr
metre.

I've checked that. Continuity where there should be and not otherwise.

Any other things I can check before I really lose my rag at destroying a
brand new radio?

Sounds a daft question but you haven't inadvertently pressed any other
buttons like PA or an attenuation when trying to set up rig? Iv seen this
done before. How long did you key the radio up for when you trying to SWR
it? How high was the SWR?

Can you run everything by as again and Im sure someone in this fine and
friendly NG will get you going.

Thanks for the friendly help... and spelling correction!!

I set up the rig today, its a Midland 48 plus multi.

Aerial is a full springer on the rear spare wheel carrier (Jap 4x4).

I put the swr metre in line from rig to swr metre to aerial.

Tested on uk ch1, SWR half way between '3' and the 'set' mark in the red.
Same result on ch40 uk.

Changed aerial to a short rubber duck, same result.

Checked all connections and continuity's on the co-ax. All fine.

Springer back on and adjusted the length. Tried test and SWR metre showed
nothing. The lcd display on the rig shows nothing happening ( I mean the
metre lcd's. Not that I noticed if it did read anything when the SWR worked
as I was concentrating on that.)

Max time I keyed for was a second, just long enough to see where the needle
on the swr metre read.

Rig still works PA fine.

It will I suspect go back to Alan UK for repair (Rig bought from 4x4cb.com).
I'm frustrated as its the first time I've set a cb up and I followed guide
to the letter.

My bet is on a dead short in one of the antenna plugs or the coil in
the antenna. Time to disconnect the lot and get the meter out to check
for continuity between outer and core.

Move the antenna to the roof and recheck. You've got the antenna having
the signal bounced back to itself from the tailgate.

Also if the spare wheel carrier is a typical one, it's not metal and
isn't connected to the car chassis so you're running an antenna with no
ground which will give you a high SWR unless it's one designed to run
like that such as a dipole.

mikeFNB

let go back to very basics here.

connect the CB to the SWR meter
[CB or TX socket, with NOTHING on the AERIAL socket - yes NOTHING]

put the meter in FWD and wind the knob full clockwise
key the radio, its needle + the needle on the meter should bang right over
to the end stop.
if it dont
radio is screwed
or
patch lead is screwed.
or
SWR meter is screwed
simple.

the only way you will screw the radio is transmitting into a short circuit
[shorted patch lead i bet!]

putting your aerial on the spare tyre mount is a bad idea
you might aswell shout out the window! you'll get further

roof in the mddle is best
got a magnount?

The springers are cut for CEPT frequencies.. to get some sort of acceptable
swr, start by cutting an inch off the top of the antenna...

Sounds a daft question but what it the spare wheel and 4x4 made of?

what part of the country are you in?
there maybe someone locally that may help you run the tests, and show you
how its done.

i do not think your radio is at fault.

Steel chassis. Took paint off the wheel carrier where mount goes. Get good
continuity between the carrier and the chassis.

checked patch lead. Continuity between middle and middle and outer and outer

Anotehr test for that?

Agreed but a compromise was needed. Its easy and neat to fit there with no
body drilling.

I'm in Lochgilphead, Argyll. Appreciate any help offered!

I'll contact the website that sold me the set up, they pride themselves on
their customer service so we'll see!

I am near Edinburgh, not much help but I don't know if you ever get near
here.
You would be extremely unlucky to have killed the radio by doing that as
there should be some sot of protection built into it.

Well the units been sent back as requested and I've been recommended an EGP
to go on the bottom of the aerial. I've been back over all the cables etc
and all seems fine but he's sending me another cable to be sure.

By chance I'm in Linlithgow next weekend so if it's still giving me probs
I'd appreciate an experienced eye cast over it.

you say that you have mounted it on the spare wheel holder?
i take it that you have a 4x4? and that the wheel holder is halfe way up the
door?

it could very well be that the ariel is having the signal reflected from the
door and/or roof of the vehicle.
there are alot of antennas that do not like to be to close to items, even
too close to a wall can upset a swr reading.

but thinking about the meter not reading a signal, then i doubt it is only
what i have just said.

This is the point you need to focus on. Whatever the state of the aerial the
signal meter will move when in TX. Even with no aerial it will go up. Now,
either you have simply knocked it onto PA by mistake, put it onto low power
by mistake, you have stretched the mic cable too far and broke the TX wire
or, as previously said, the radio has gone kaput...

well i've not got you as a total fool
so i'll say the rig has gone futt

anyhow, very diff to do that even into a short, it should stand it esp a
midland
so i'm glad the radio is flying back to the shop
prob a duff one.
lets hope you get better luck

now this type mount idea, is, as already said, going to really screw you up.
your range will be very limited on both tx/rx

in the words of him on dad's army
an aerial with half a body up its length...don't like it up 'em, they don't
like it up 'em

Get in touch if you are still having problems.
I should be able to diagnose the fault one way or another.
usually its earthing, but with 27MHz this is usually less critical than with
lower freqencies.

Cheers.

I got the new rig today and plumbed it in. SWR 2.5 across UK and Cept. I've
slotted in an EGP which has brought SWR right down but I guess I'll lose
distance in TX and RX?

Happy I've not destroyed another rig. I used same cables etc as before so
I'm guessing the rig was dodgy.
