Which Is Best For A Cobra IRF520 Or ERF2030 For The 40 Watt Mod

[Handy Andy]

Wow Andy, have you ever thought about writing a book?

"A Funny Thing Happened On The Way To The Forum" - a play/musical parody done about the Roman Empire...

However...
"Wrote A Book Answering Questions On A Forum" - doesn't seem to have the same "ring" to it...

How about...
"Core Dumps - What You Can Really Obtain By Meddling In Some Else's Medulla" - NAH! Sounds more like a Stephen King Horrific Novel...

I'll try to think of more titles...

Stay Tuned...

Thanks though...may not always be the right ones - but I do try...

Why not just get a linear and use that? It'll be far more stable, you're not over-working the radio past what it was designed to do, you've no worries about putting out crap, you've no worries about heat dissipation which I see everyone has failed to address, and you can get much more gain. Going from 20W to 40W is as pointless as going from 4W to 8W, it gets you half to a single S point.

From what I have been told is that it takes 1000 watts to see 1 s unit.

From what I have been told is that it takes 1000 watts to see 1 s unit.

Actually, 1/2 S unit increase takes a doubling of output power. Double your power twice to get a whole S unit increase.

Agreed. The best jump in signal you will ever make is when you go from a 15-20 watt radio to say a 300-350 watt amplifier. After that each time you want to impress your listeners you will have to double your power to gain 1/2 an S unit.

Here is a great chart on this.

Gosh, I had pretty good luck with the 13n10 and biasing it with a small voltage regulator on a "parts only" Cobra 29 I bought off ebay. 8 watts carrier swing to about 39 watts.


My wife, however, was totally unimpressed so I told her to use the broom she flew in on to sweep up the kitchen floor.
