I think some of the posting of the wattage is far out line in the fact either the voltage has been ramped up or the like bob_smith said overmodulation. I did nothing to turn up the modulation on this brand new cobra chrome special edition to achieve the numbers I gave out. I ran it honestly at...

I replaced the capacitor at c42 with the suggested one by cbtricks,but did not do the j36 removal and the results are as follows. dk = 12-14w, pep = 75-80w, and just for kicks I took a RMS reading even though it doesn't mean much it was doing around 38-42 RMS. Now that is quite a bit of RMS and...

I did this mod and am somewhat impressed. I installed just a few minutes ago and got a dk= 5 1/2 and swings to 55-58w. With modulation set at 18-20% and swings 100%. I have not installed the 1000uf at j36 and 33ohm resistor on the other side. I am running at 13.8v and it pulling around 5-7 amps...

Well I adjusted r212 and no extra modulation. I am wondering if the amc circuit is faulty. I put my ohm meter across the vr14 pot and when adjusting it I noticed the value didn't vary much at all. The potentiometer has a 102 stamped in it. What is it suppose to be a 10,20k. If so should I notice...

I checked out R237 and it is 100ohms; but the interesting thing I noticed is where R212 should be there are two prongs from a potentiometer on the solder side of the board. Do you think if I adjust it will it make the modulation go up?

To answer purenrg it is a AM/FM radio and is a single final radio with a 2sc2166 for a driver and a 2sc1969 for the final transistor. Unit_399 I will check the resistor at this location and report back in just a little while. The factory specs for the VR16 which is the low power setting says to...

I tried lowering the dk and found the best result around 6 1/2w; but the modulation set point was only 70-75% and swings to 100%. It is an improvement but not what this radio should do. This radio should be set around at least 60% and swings to 100% and a dk between 8 and 10w and should hit a...

I will try and lower the dk to around 4-5w and see if will let the dog swing its tail; but I really doubt it. I think there is something going on from the factory, it has been a dog all its life. It should easily go to dk of 8-11w and show at least at 40% swing in modulation. So I should be able...

SRA-158 is a ceramic element and will give you the most modulation you can possibly get from a radio, it is a stock mic for the RCI products but is probably the most sensitive one on the market and will make any radio swing full modulation with little effort because of the mic element. As far a...

I tested it with my astatic 636l and my ranger sra-158 so it is not a stock mic being used. Like I said no mistakes as far as testing it; VR14 is turned all the way up and it only swings from a set point of 95% and swings to 100%. A 5% swing explains why my friend never was impressed with this...

It is going through my dosy 4002 psw and into my 1.5kw palstar dummy load. So no mistakes there; it just wont swing and the guy that owns it has owned it since it was new and never seemed to have the big audio it should. He had me put it on my meters and it will dk 10.5w and only swing to 20-21w...

I have tuned the radio up and can not get the modulation up on this radio. I have cranked VR 14 all the way up and it is a dog. Is the limiter that I can cut that will raise the modulation and will it effect the radio at all. Thanks for any help.

If you choos a switch on the front of the radio then do yourself a favor and lable the wires as you remove them from the switch. Then if you want to remove 5 yrs later and put it into another radio you can return the radio to stock. I have done this mod several times and if your just an...

I also work for a freight company and several of my friends use a 5 1/2 ft Francis 5/8 wave red or black fiberglass antenna, you can cut the fiberglass antenna down in 1/8 cuts until you get the lowest swr. The coax I would recommend is a heavy duty gray type with amphenol ends on it; don't be...

I wanted to add some more opinions on the Skythumper. I still recieve compliments on its sound and clarity, I use it with my General Lee(Peaked by Sparky) and once in awhile I will switch it out with my rk56 and 636l. They all said switch it back to the Skythumper and it was not just on that...

Hotrod that is exactly right. Coming back to the original reason Uniden got out of the business of making the sideband radio is the fact they were making a high quality product with some expensive quality control costs in the Philippines and was making a radio really only for a more serious cb...

9c1driver you may be correct that RCI has used Uniden as a template or platform for their radio, but like anything else they have made some very good improvements on the product and from what I can tell they are the best platform for ssb if you are a serious ssb user. As far as the cost and 10m...

I was thinking to myself if you're only the second person with a galaxy for him to repair than I would say this guy is doing it as a hobby rather than a profession. There are at least 7 simliar radio to your 949 chasis that are out there that I know of. The galaxy being one, ranger,texas ranger-...

Well when I looked at the price I thought that is a little more than I want to spend on my hobby. That thing looks quite complicated and would take awhile to learn how to use. And a $900 who says its even calibrated. I p/u my o'scope,freq counter, watt meter and all else for less than $500 and...

I don't know if I agree with you on the issue of Uniden being one of the best producers of ssb radios. I think under all the name plates that RCI produces one of the best ssb radios in the 2950-2970 models. Uniden made an exceptional one in the HR series. But I think for the serious ssb user the...
