the only thing I could find on this radio is the owners manual and it shows all the channels you can get. the manual is in a few different languages and it is in english starting on about page 36 if this will help you any. no schematic with the manual. looks like it can get a lot of extra...

the only place I know of that has channel kits now is lesters truck stop in Florida and his sale page is Lescomm I think it is. thought I had a link saved for his site but do not..you can do a google search and it should come up. here is a link to one he has for sale on ebay. you can message him...

I do not know what this mod is either. what does it do?

only one used one for sale right now and this one has the dual clarifier. all the new radios for sale is the factory picture and not the actual radio. when I 1st saw the difference there were several used 980 for sale and some had a single clarifier and some the dual.. I posted the link to the...

sounds like the person that answered you has no idea what you are talking about. they did not give you a straight answer to one having 2 knobs and the other having 1 knob.

I never saw where it said if he found the problem or not.

look on the last page of the owners manual I left you a link to. it has their contact info.

check the voltage in step 1 in the vco section and see if the radio is locked on freq. if this is not right the light will not change. also the age of the unit you may have a bad cap causing this. the radio may need to be recapped before you can proceed on.

here is all the info from cbtricks on the magnum. did not see any thing like this in the tech notes for your radio. I would contact Magnum and see if they can help you. might be your best bet since not many of these radios are around. in my 30 plus years working on radios I have never seen this...

here is one 237 book for sale. https://www.ebay.com/itm/Sams-CB-237-CB-Radio-Series-December-1978-Description-has-Models/253689433578?hash=item3b11118dea:g:BREAAOSwi49bIsRc:rk:1:pf:0

this radio is in the Sams cb237 book if any one has it and would share the alignment portion with you. if you would google the radio it brings up some info to adjust the output as far as power.out

. Modulation 1. Set TX Channel 19. 2. AF GEN. Output 30mV. 1. Adjust VR5 for 90% on the modulation Meter here is what the service manual shows for the 25 radio. not sure what the inside of your radio looks like. if you do not get any more modulation out of it this way it is a chance you have the...

How much modulation are you getting out of the radio now? about the only mod I can think of for this radio would be the cap and resister mod to lower the dead key just a little and it will give you more modulation. you can put this variable in it or just put a cap and resister in the location...

Riverman when I 1st noticed this there was both kinds on ebay. that was when I noticed 2 different versions.

you can even take a picture of the board with these and print it off your computer. they are pretty neat to use.

its just a microscope and you can hook it to a laptop or desktop computer and it will blow up the parts by about 500x. you can even hold it in your hand and move it around to look at the solder joints. I only paid about 6.00 for mine a few years ago and was just looking and China has them marked...

here is one like I bought. this one is from the US as far as shipping. if you are not in a hurry you can get them from China for about 1/2 this price or even cheaper. look at the black one. they have a drop down box for silver and black. the black one is what I bought...

I bought it off ebay a few years ago. I will see if I can find one like it.

I copy that Staybolt. I am 67 now and do not want to even work on one I have bought for myself with SMT. depends on what is wrong with it. I even bought a microscope to see the parts easier and my hands are not steady enough to do smt parts now. using it to blow the image up on my computer makes...

I use a 75 ohm . and a 220uf cap. or I use the variable mod as shown in the link I left for you http://www.cbtricks.com/radios/cobra/mods_&_info/graphics/Cobra_Uniden_Var_Pwr.pdf
