Check the PD coming out of the PLL, the voltage should go up has you go up through the channels. Check the VCO. Check the Fin. I do not know what PLL is being used as you have not given all the info required. See www.radiomods.co.nz/forum/viewtopic.php?t=312 my apologies rick and admin you can dele...

frogman296

did you try a different mike??

if not...sounds like a cold or cracked solder joint

frogman296

nothing of the sort has been done to the radio...baffles me..

frogman296

what you were hearing is skip....and 1.2 is a right fine and dandy reading

frogman296

what type of vehicle is this going on??

frogman296

i have great power on a uniden pc76, that is until i go past channel 24...then i have NONE...no power whatsoever

any help would be appreciated.

thanks fellas..

frogman296

good ole youtube....good stuff...sometimes the troublemakers need a lil lesson ..

btw i found the vids, he should be ashamed

frogman296

anybody have any info on this radio??? i would like to give it a lil more oomph

thanks fellas..

frogman296

how do you know the channels are all messed up, without a freq counter???

frogman296

if the radio has 1969 on the finals...i would leave it alone and give it a peak and tune

frogman296

well i tried this lil mod....and i got nothing..it did nothing...darn

frogman296

im gonna give it a shot later on today, no harm done...peace

frogman296

i know that vr8 is the am power, and it is a 10K pot....can i just remove this pot and route it to a 10k pot on the front of the radio.

frogman296

frogman296

i always recommend no less than rg8 or rg 213...the most important part of the system...antenna and feedline...

frogman296

i would settle for the low and high power adjustments...i can remove the low power pot and wire it into a separate external pot..

the only adjustments that i find, are for the grant with the band switch, mine doesn't have that.

frogman296

are you wanting to still install the swing kit??

if you are just gonna install the jumper back in..solder it in the same area of the foil(wheres its lifted) then to the other hole...you can do this on the foil side of the board

frogman296

Ok it was D23. I replaced it and it's working great. 2@ $0.99 at radio shack. Thanks for the help. Another thing I'm trying to learn is positive side and neg. side. I have a Cobra 25 that I tinker with trying to learn. I lifted the foil trying to add a swing kit. How do I identify where to hook up ...

frogman296

lower the DK on the amp...let it swing...

frogman296

I think it is better to mount an small CPU fan at the back of the heatsink :roll: . Then the "Magnum" sounds even better :D In normal CB use i regular the power output down to 10 watts. Then it is ok with the temperature. 73's, Ralf ralf is right..lower the power and let the radio swing f...

frogman296

i would go magnum over the connex, with the stryker coming in a close second... i am assuming you are not a ssber, if you are looking into connex radios, am i correct? if you want power go with a radio and external amp combo, a lot more efficient. the RCI 2950 was mentioned above, awesome ssber for ...

frogman296

I got a R.c.i.2950 dx from Copper ,It also came with the C.B. channel chip not installed .Just like I ordered , I figered I had too set the power while I was doing the Claifier mod (unlock) at the same time.. Man it still works great for $262.00 With shipping :D thats a bummer as well i take it you...

frogman296

if you are sure its not conditions...you really should send it in to galaxy...or get in touch with Ray, he is the best when it comes to customer service.

frogman296

i wasn't a big fan of mine...i would put up a 3 element beam and tv rotoro over it any day of the week, and the 3 element will make the super scanner beg for mercy.

frogman296

d17...it is in the rear by the transformer...1n4004 is the diode number

frogman296

are you referring to the "A" channels??

frogman296

hey fellas..i have a president grant that i want to run into a 2x2290 box...but this radio has no variable power.

anybody have the locations where i am to add some parts??

thanks in advance guys, i can't wait to get into the SSB way of life.

frogman296

onboard amp??? man..those are a disaster waiting to happen...did it some with some sort of "rf shield"??

frogman296

fm will make the radio run hotter anyways, as it operates at a higher duty cycle

frogman296

i would go with the first link

also...i buy my parts from rfparts.com

frogman296

are the coils at the back of the radio, spread?? has there been wax scraped off of some adjustment points??

thats super

frogman296

I just got one these radios, the talkback switch on radio's stock 4 pin mic does not disable talkback. The tb is active all the time. Is there a simple fix to disable tb, I never liked or use tb. I would rather use an Astatic power nc mic as well, and tb always feedbacks/squeals with any power mic....

frogman296

i know this might sound silly...but is your mike working correctly??

frogman296

i have no idea..im across the pond...i'm sure someone can chime in though

frogman296

welcome to the forum, i'm sure you will fit right in....and yes, rick is a super technician thats for sure

frogman296

im not sure how many knobs there are on the mavs...but....what i do is adjust the "load" until i get max rms on the bird meter then...i "tune" for max rms...i usually try to tune between the 2 channels that i use the most.. the load will not change as long as you use the same ant...

frogman296

i had the same problem...ended up being the lil plug that the speaker wires plug into...had to remove it, and i just soldered the wires to the the remaining pins

frogman296

middle of the roof

frogman296

i would let a quality tech wave his hand over that radio..tune it right

frogman296

older radios....phillie cobra 29 or uniden pc 76xl

newer..uniden 68/78

frogman296

i totally agree with rick...i would leave it alone, not worth it

frogman296

Unlocking the Clarifier 1) Remove D52 and R44. 2) Remove R174 and place a jumper in its spot. 3) Follow the Red wire from the clarifier control to where it attaches to the PC board and unsolder it from the board. 4) Resolder the Red wire to the PC board ground. 5) Follow the Orange wire from the cla...

it really was a shame..these radios were fine looking, with lots of features...but, they were lemons for the most part

frogman296

do you have an external frequency counter??

i would hope you have a quality power meter..

if you have any doubt, send it out..

frogman296

http://www.galaxyradios.com/regulator.html

are you sure it is the power supply, and not the freq counter??

frogman296

did you clip the modulation limiter??
