replaced the original mosfets and works great!!!!!

Dropped in new 13n10's. Terrible output with high swr. Needs tuning?. No heat generated from transistors - hs cold. Added light to on -off switch so I know voltage present. Tried thermal pads on backs of mosfets but blew 6.3 amp fuse on board. Removed pads and fuse. Works again. But unit needs...

it's all good...just playing with stuff.

Going to install mini 12v fan where mic connector was....also a multicolor led to on /off switch.....Robb gave me the idea to go with different mosfets so I will try them. The old mosfets were a struggle to remove. I will have to fix up some trace on the install. Like to get some watts out that...

Gonna drop in 4 new irf520n's. Really cheap on ebay. Will check output and deal from there. Don' t know much bout tronics but learnin'.

Hey ROBB it's me Unit 511 from our contact on lower 39 on 2-6-2015 at about 5:00pm. I hot glued the switches in so it looks like a regular cb. I could spray paint the hs and hide it a bit I guess.

I have installed a RM ad203 mosfet board in a trc453 radio in the past..... the radio crapped out and I had this board with no home. I could not just leave this thing alone. I had to play. I took the guts out of the trc453 and kept the AD203 in it. I bought a used trc453 off of ebay... but that...

Just playin' with some toys. Trying to get my hands wet. I am learning and having some fun,ya know? I am getting a 959 with mods very soon. A magnum will be one mod. 73's

I replaced a 26v 100mf cap on the board. I cut the leads tight to the underside but I did not notice that the legs had touched the heatsink. I saw the top of the cap had a slight bulge and that annoying relay thing was happening again. Sooooo again I replaced the cap but this time I used my nail...

So I have the same problem ...the relay stays in. I have to shut off linear switch to drop relay to get into receive again. This happens intermittently. What up?

Or u could just get a gainmaster.... Happy Holidays to all...Unit 511 said that

Time to buy a Gainmaster?

TOASTER????? How does audio come out of a toaster? I have heard of this but don't understand how this happens.....

Follow up on AD 203 Install Still works great. My radio however started to go" funny" on me. When I turn it on the audio would be so friggin loud it would hurt your ears and the volume control did nothing to reduce the volume. When I jiggle the band selector switch the volume would be...

Or you could have bought a Gainmaster.....hehehehehe

Really ...Flashlights ?????? I do have several but i would not call it a collection. Different types for different jobs.

And what about remote control boats, planes, and cars? Do u also like these? Can u say profiling?

Love to fish- have all my life. Never owned a boat- too much trouble. But like going out on them. Is there a pattern here?

While listening to my cb as I was watching tv I overheard the local guys talking about going to the range to shoot some guns and then they talked about there ammo ,reloads, favorite guns etc. I was amazed that MANY of the guys on the radio loved to go to the range and shoot....You see I have...

Well I have been using this setup for about a week and is working nicely.... Still no meter. Can talk skip to midwest no problem but could not make it to west coast yet. Talking to my locals the aluminium heatsink does get warm.....but because it's on the outside of the case the heat is not an...
