I was wondering if the MOSFET conversions for Cobra radios where any count or if they where worth messing with.

I have done some on 29's and 25's with great responce. If you are wanting to learn then they are great to work. Yet I would suggest that you take the time to read as much as you can before doing so.

I really think it depends on the year of your cobra as to what you want to do! I have done some of the newer cobras (LX LE) and had great responce..The older ones are a little easier! But don't let anyone fool ya... Go down to radio shack or mouser(depending on where you live) and buy the parts yourself..It's allot cheaper ! Lots of sights out here that spell out all the parts and resistor number for you...Do it yourself and save your cash!!

It's not worth it in my opinion. If you are looking for increased output, buy a small amp (RM or such). The small wattage increase you may see from the MOSFET will not be seen on anyone's S meter.

But it's just so much fun to do!!! And it's a great way to learn to work on your own equipment... Just follow the directions on the web! Super tune is fun too!

I would agree that if you are an experimenter and like to tinker for the fun of it, or for the learning experience, then by all means go for it. That's how you gain valuable hands-on experience. But as a reliable mod, the MOSFET change can be troublesome. MOSFETS (at least the cheap switching types they typically use) have a VERY narrow linear range and the bias setting is critical, and subject to drift, and is very hard to nail down over the long term, without proper temperature compensation. Even factory made rigs that opted for MOSFET finals have had issues. |
