Those dual 1/2 w resistors you are talking about are shunt resistors between the base emitter junction.

Here is a better pic of his amp for you

The resistor IS the biasing resistor. It connects to the base of the transistor and pulls the base of that transistor downwards and sets the operating DC bias point below the cut-off point in the DC load line so the collector flows less than a 180 degrees (half cycle) of the AC signal. CLASS C...

Most of those stainless steel whips taper from 3mm on the bottom to 1.5mm on the top

Aluminum is lighter than fiberglass.

Crambone. You cannot wire a 4 wire Turner plus 3 to a 5 pin Cobra 2000 unless you add another set of contacts in the microphone to switch the receive line.

They always get you with that last line on the can. Can't sell it to ya unless you have a license :(

A very Merry Christmas to my family here at WORLD WIDE DX. Much love

They are talking about the IMD here. I wouldn't use the spec sheet as "the bible" so to speak. Use it more as a general reference only. If you do some research you will find that the test jig Toshiba used for the 2879s had no feedback circuit. Secondly, our radio specifications are measured in...

Good eye, Dan,

Yes, That is all copper. It's new. It has the strips on the transistors base so the resistors can go from there to the ground to keep the conduction angle correct, seeing class C generally needs negative bias of some kind.

I guess you could buy it and run it until it blows up then return it saying the item wasn't as advertised....lol being a class C and not AB. All sellers are responsible for their listings right??

Hey, Shade. Your correct. That 16 pill is biased class C. He has the base of the transistors tied to ground thru resistors. That photo you have isn't angled correctly to see but this one is. P.S. Most of us know better about seeing the "AB1" stuff on transistor amps Ha Ha Ha. .

Good advice, Sonar. With the drive figures you posted, your amp will last you a long time.

Hey 357, I'm with ya on that one, brother!

wow. Thanks for sharing, Woody

"DELTA" is in reference to the average rate of change of "f" which in this case is 1kHz

Your correct. Pin 7 The 20LF6 used the 12GW pin out and the 26LX6 used the 12JA pin out.

The cubical quad would be nice. It's a little larger and catches more wind load in comparison to just a yagi on the horizontal. I ran the Signal Engineering 8 element quad and the Lightning 4 element quad. Worked well, but I decided to try something new to me. I'm using just a 5 element on the...

I didn't hear you in there this morning, U812. Spoke to a couple of guys in Austin. Then I had a guy call me from Mexico. 110 Scorpion I believe. I haven't heard my buddy SOB#1 in there for awhile either. We are supposed to get some tornado weather moving in soon. I think Monday during the...
