need opion

Just to keep your thread alive........I have never used one and don't know what they cost so I can't intelligently answer that question. I do know I am not sold on these new radios that use the new mosfet transistors. Would rather have the older radios with the motorola transistors if for no other reason than durability. But I'm old and opinionated!!

 

Afternoon Mike .....

After all the times you have called ME a old look at who is pulling that cop out

I Have to agree with you MOSFET transistor are not too forgiving but if protected right there is no reason to think they should have a high failure rate ... OTHER ..... than the FT-100D VHF/UHF had .... it is the benchmark for how not to build a radio ......

That said run them cool and they will live long .....

 

New MOSFET (how I was taught to write it when I was studying Electrical/Electronics Engineering between 1983 and 1987) transistors?! Funny, when I was studying Electrical/Electronics Engineering - we were studying both vacuum tubes and solid state transistors (BJT and MOSFET are the two I remember but could look up the rest, I still have my college books!)

Metal-oxide-semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is what I was always taught was a MOSFET transistor (actually should drop the "transistor" from that phrase as it is redundant because "transistor" is part of the name). BJT is a bipolar junction transistor - again do not need to append transistor to the end as "transistor" is part of the name.

 

I recently replaced my General Lee with a Stryker 447 and couldn't be happier.

I bought mine from Custom CB Radios, and after they did their tune, it swings on my meter to about 70+ watts...They have a video on Youtube of one doing 80w's after tune, so my findings were close enough to their claims.

The 447 IMO has a better receive than the Gen. Lee, plus more power. A General Lee will only do about 40w's, unless you get the New General Lee HP that does about 100w's.

Cost of the 447 vs the Gen. Lee is a little more, but not that much, and worth the extra $.

As for as the Mosfets go...Just about every radio being sold right now will have Mosfets in them, so like 'em or not, better get use to using them!

 

Or get used to changing the cheap-ssɐ Chinese copy-cat bipolars.

 

Got me! (I am old and opinionated......and I like to argue too, bet you didn't know that!

With all the high SWR problems on these new trucks, and the many truckers that don't bother to have them checked and set, I foresee a lot of blown finals. It will be good for the repair shops though.

 

NEW, as in new in CB radios. FWIW, I am not a tech, but a user of CB, therefore I don't really care that I wasn't "technically" correct, but thank you for pointing that out to me. (I'm sure others were equally impressed.).....................

P.S. please don't take my sarcasm too seriously.......all in fun.

 

what type of radios do you guys run

 

The MOSFET and FET have been around a long time Back when I was in the army ( late 60's ) and between my 4 years of electronic trade school ( 1963 - 1967 ) and college ( starting 1971 ) I was using 40673 dual gate MOSFET's in many VHF preamps in the late 60's they and NUVISTA tubes like the 6DS4 were the rage in low noise amps.

MOSFET and FET's act more like tubes than junction transistors and can be HIGH Z input devices like Tubes while most bipolar transistors are fairly low Z.

EARLY MOSFETS were easily damaged or destroyed by static or even a strong radio signal YEP lost a few myself but building in diode protection helped to make them a bit more reliable.

HEAT is the killer as a rule If you keep them cool they will live long ....
