Cobra 29 LTD chrome

[smoke blower]

I have done serval cobra 29 mosfet mods and always came out with 35 to 40 watts. I just did this mod to a cobra 29 LTD chrome and can only get like 20 watts out of it. Had anyone had this issue if so what was found that caused it.

Cheap counterfeit mosfets.

Cool I have a new bunch of them and never tried to change it out maybe I can try that. They are 13n10

Probably a cheap 520 remarked as a 13N10, it happens all the time.

Yeah I haven't had this ever happen and this is out of a new batch I bought and I never thought of being some bad ones , I get them from the same place as always but they could have changed up is my thought

did you ever try another Mosfet in the radio? as posted some of the mosfets are not as good as others. i got a batch a few years ago that were the same way. put one in a Galaxy 959 and could not get the new batch of the mosfets to swing over 20. even did the dual final conversion and it still would not swing over 20 watts with 2 mosfets. got a couple of the older ones and the radio would then swing to about 40 watts.
might be a good thought about the batch of mosfets you got.

Yes I tried another mosfet and it still only put out 20 watts so I have ordered a few new ones should be here Thursday so I will try one of those

the ones I had would not go over 20 watts even with 2 of them installed. the radio would hit 20 watts very fast . a lot faster than normal so that was why I thought about getting new ones when that happened to me.

Yeah I am going to try the new ones and see what happens this weekend and I will let y'all know what the turn out is
