Steel Rod CB/MOSFET finals on cobra 25

Ive only used him for a repair and he did a good job at a good price. I had CB Shop in Cartersville GA, in the TA at exit 296 on I 75, do a mosfet upgrade on a Cobra 29 LX a couple years ago, his Dosy was showing a carrier of 10 watts swinging 40, but despite the fact I didnt believe the numbers the radio was loud and clear, but it was loud and clear stock. Bells CB has several videos showing radios with mosfet upgrade and they show 6watts swinging 28 to 30 not much of and increase or stock 4 watts swinging 15 to 20 watts to justify the expense, IMO. There are some radios that come stock with Mosfet final like the Galaxy 929, 949, 959, and some of the newer Unidens like the 880 and PC 78 LTD.

 

By the way I had the Mosfet upgrade done before I started reading this forum, especially the thread The Peak And Tune Myth, lets say it opened up my eyes. I have yet to pay for a peak and tune since and have been using Cobra 29 Lx and Bearcat 980 stock OTB.

 

Before mosfets the final upgrade was performed with the 1969 swap but if Im not mistaken there is more to it than just replacing a final , I believe modifications have to be done to the driver section. I think the main reason every manufacture is going mosfet is because of price, even though they do yeild more power, but is it enough to really make a difference, dont know Im not a tech. I do know that I have a older General Lee with dual 1969 finals and I will never part ways with it.

 

The difference between Kelly's work and steel rods work is like night and day. If you like Kelly's work you're not going to like Steelrods work.
Kelly does better work than most, although he doesn't have a clue as how to increase or decrease attack time of an amc circuit and only allow specific freqs to pass @ a given voltage.

 

I'm not super impressed with my 880 out of the box. Swr are near 1 and only gets out and receives about 2-3 miles best I can tell. Of course it could be my 3' fire stick but it's mounted atop my car carrier so I should get out decent I would think.

 

I have a 880 that I bought about a year ago with pilot points when it was on sale, and OTB the modulation was rather low but if you open up the radio there is a modulation pot that can be adjusted to increase modulation to 100% , and with the use of a good power mic like the RF limited 2018 extreme echo it will be loud and clear. I just dont use mine because the static level is just to annoying.
