Blown Up Anytone AT-6666

[Martian]

As an aside to the above.. I typed this in and then removed it but upon reconsideration, why the hell not. It will make the the CB guys cringe a little.

I am working on a Christmas tree project and I needed some MOSFETs to switch some moderate loads. Normally I would buy a tube of IRF520s from Digi-Key and use those.
They have been my go-to N-Channel MOSFET long before they were used in CB radios.

But the ERF2030s on Amazon were cheaper
Guess what's switching my Christmas light displays this year?

Hey, they work.

Wondered why my CB radio lights were different...

ok thanks, I'm beginning to think I should have bought something else.
by the way I like your avatar, is that yours or just a wish and what cal.

its my own rifle its a stevens 300 in 22-250 .had lots done to it.
Thank you its a tight group coyote getter

Looks nice

Looks nice

thank you.installed that boyds stock.milled barrel to reciever blueprinted it.worked trigger over.its a go to rifle

Ok now I've figured out how to work the page on my phone, that merage 88 I saw posted in the chat channel looks nice

Whatever you do, do NOT overmodulate that tree!

Well they are cheap quality radios.

Bone head remarks. They are better made than your galaxy or ranger radios. I’ve not had a problem with mine but it’s a later version. The first versions had transistor issues. If you look inside they are surface mount parts & it’s put together nice . Looks more like a commercial type rig than a DX radio. I set the power for 2 1/2 watt carrier with variable knob fully counter clockwise & modulates to 35. SSB peaks to 80 watts pep. I could go more but why? Use a amplifier for more. Reason most of these radios take a shit is because most try to get every damn watt possible when it’s not needed. One S unit you need to double what it’s doing now , maybe a little more. Just because a transistor is rated for 20 watts does not mean try to get that or more. This isn’t just to you it’s to everyone. Read up on the transistors you are gonna be using. You can learn a lot from reading info on them. Every radio made is cheaply made in one area or another to cut cost. It’s the overseas way.

Ok, here is a fun one!

I've had an AT-6666 since March and have used it at home and in my mobile. It has worked flawlessly with stock mic, power mic, 5/8-wave Sirio in the mobile and my dipole at home at all power rates.

Last Friday when driving home from work, when I keyed up it showed SWR at 17:1 (it was 1:1 in the mobile) and then it died.

I was wondering what caused it? It wasn't hot out, the Mic was turned up half way. I'm having it replaced for free but don't want to make the same mistake again -- unless this is just how they work... the just randomly blow up at some point.

Suggestions?

Buy you a adapter on Amazon that your pl259 screws on & you push it on the so-239 on your radio so you aren’t stewing on & off the antenna all the time. Just push on pull off. It’s a W5SWL push on pl-259 adapter. I love using them on my connectors on my amplifier. Some tight spots are hell to unscrew pl-259s.

 

[Recon]

Or use a bulkhead or drill a hole, though still not the most optimal choice for an antenna. But I’ve had that very thing happen with my own antenna and a lesson was learned.

Maybe is has one of those "funky" two-piece PL-259 connectors that can be disassembled to make it easier to pass the coax through the firewall. Could be a disconnection there. Ask me how I know. Lol...lol.

Wow... Okay.. stand by what I said cheap quality radios

yep most of this chicom crap is substandard disposable junk. from the land of ALMOST RIGHT
