Hi...
I would like to kindly request that someone whom knows the Cobra 2000GTL main circuit board inside and out, lend me a helping hand if you can afford the time to do so?
Lots of pics at (some pics are huge) : Index of /tools/pics
I use Picasa to load large pics and the zoom in and...
fnkycoldmedina... how can you tell 100 ohms? Is it not burnt too much to tell for sure?
Dead keys over 400. Swings near 500.
If pill is out... must be the 455 I mentioned above, the 2290's all seem to be working.
Thanks,
John
Help identifying amp please!
So I can hopefully fine a schematic.
I need to find the schematic so I can figure out what the value for the burnt register is. (in the pics) And of course I need it anyway.

Pre-Amp is out on amp. I'm hoping the resistor is the issue...
Thank you Spider...
That is the kind of info I am lookin for.
However.. before I do that, let me give you a bit more info
based on your idea.
I use a hand held next to my work bench to help test radios.
It has an LED signal meter.
When the Connex is keyed and the mic spoken into...
Having some TX issues...
Would you guys please have a look?
I put up a page to explain the problem and put up a pic as well.
Connex 3300
Thanks in advance for your help,
John
Would someone be kind end enough to tell me which coil/s to tune down to about two watts out?
Ive heard there were 3 different slugs. I hope there is just one. That would be much easier.
All I wish is the basic tune down and nothing else.
The 29 is to drive a Palomar 300.
Thanks,
Pede
Thanks Robb...
Just getting back into radio after 20 years. Back then I used to "Peak & Tweak" (that's what we called it then) all my fam & friends radios. Never made any freak mods but could have. I went to ITT tech for awhile before I quit and went into the navy.
I can certainly buy some...
Thanks Robb...
Yeah, I did alright. I go to a lot of flea markets and yard sales and negotiate like a demon. hehe...
BTW... do you know where I can get a simple power mic amp circuit and a speech processor circuit. You know, the ones that go INSIDE the radio.
Thanks,
J
May I have some thoughts and opinions on this radio?
I just purchased one for 10 bucks.
Talks and receives just find. Just need to get the lights going. Meter and channel selector are all that lights up.
Also... I can hear myself talk through the speaker when I key it up. Sounds a bit...
Hi Guys...
Quick question please...
Good 50 ohm coax is expensive. But I just happen to have 3 500 foot rolls of high grade 75 ohm coax.
What can I do for using it for cb's. Auto and/or base.
Just getting back into 11 meter after years of having no clue what is going on in the CB...
