Bump

If I turn the radio off, that power begins to drop as if a cap is draining.

Smoked L405 so started poking around. Chassis ground shows 12v positive. ?

Sold 100+ of these radio. Make sure ifmyiumdomget one that you get the one with the MOSFET final. This newest 2015 model year has tons better filtering. The original model had way too much RX noise. The new model also has an rf gain and high low rf power. I normally drop the high dead key down...

I actually did this set up when the 980's first came out. It worked sometimes and then it didn't. It was weird. Sometimes I would get audio and other times I wouldn't. If I remember correctly, it would always key up though. It frustrated be enough to just say STICKIT. Come to think of it, it...

Thanks for the response. I closed for about 10 days and I'm just getting caught up. Every time I try and help a local guy on something different than a radio, always ends up being s pain. Here is a pic of the board. I don't think it's the regulator you're referring to. By the way, I...

Should be in stock any day.

ps36kx going into protection mode when turned on. +/- short. Protection diode is ok but it appears there is a short to ground with a transistor. I cannot find anything in this transistor on the net. Looking to replace this transistor N416 GKDXW U MAR 138

Q54?

Perfect. Thanks. Funny you mention proper heat sinking. This thing is just free floating. Gets a little hot for that.

boomer 600 - adjusting bias lead to a bad transistor on the bias board. Can somebody suggest a replacement? - UA7805c Originally I thought it was a 9022a so that's what I posted in the title.

Google capacitor chart.

That was from it being plugged in backwards.

Gittem' Ted!

"...a real export not the phone Chinese crap..." I'm confused. It's a Galaxy or it's not a Galaxy??? Galaxy radios aren't made in China.

Oh, crud. Good to know Mike. I'll bet that radio (radios...since he went through a few of them) caused him to lose some hair.

wait...that a 2x6, not an 8 pill. Let me rethink that. Yeah, still the TNT.

That's easy, TNT1200. It's not even close...for so many reasons.
