No it’s not, it kinda looks like it in the picture, that’s a little bit of the lead of the talk back resistor that I clipped out. I corrected the wires that were passing under the antenna wire. I’m thinking about pulling c168 a ceramic disc cap and testing it. I’m looking at the schematic. It...

That is exactly what’s happening here, if I unplug the mic with an antenna connected I still get receive even with the volume turned down fairly low. As an experiment I tried that with my other two 148 gtls and I have to turn the volume all the way up. To hear even a little bit of static coming...

Well I will continue to update this thread until I have fixed this radio, I have been going over multiple schematics with a fine tooth comb. And have basically come to the conclusion that this radio is basically the same thing as an 148 gtl, just like everyone says. Although the traces on the...

I don’t believe I’m dealing with a microphone problem. The microphones I’ve been using to test with, work perfectly with my old school McKinley two other 148 gtls etc. and I believe are wired correctly. I have done some more testing this evening, I seemingly don’t have any talkback without an...

Six years later I’m bringing this thread back, I basically put this radio away six years ago and have not messed with it since.I removed the echo board six years ago. I remember that talk back had been added using a resistor on the ext speaker jack, I removed that resistor back then. I was able...

Nice, the 148gtl is worth keeping. Or at least attempting to repair if it doesn’t work.

I really like 40 meters. It is a lot of fun, you can pretty much reliably talk to someone a state or two away, night after night. 40 meters is good for when there is no conditions, you can still play radio. To me its fun to make a contact on 40 meters that is only 100 or 250 miles away. Also I...

I have been learning cw for the last six months, and i love it.I have been learning all by myself just using w1aw code practice files, free desktop software, aps on my phone etc. . Im not saying im really good at it, but i think making cw qso's at 13-15 wpm is alot of fun. I feel like i have...

It seems like conditions have been really bad for the last month or so on 11 meters. I like 10 meters. I always listen to 38 lsb first when ever i turn on the radio, to see if its worth calling cq on 10 meters. It seems like even 20meters has been bad also. I have been learning cw for the last...

Yes thank you, yes I got the tube shield, from a guy in Arizona that has a lot of Kenwood hybrid parts. And I bought a nos ge 12by7 on eBay for like 12 dollars. And the radio works now.

Yes the 12by7a driver tube is completely missing. And from what research I have done there is supposed to be a slip on heat shield on it. I have never owned or operated a kenwood hybrid before. I have already ordered a tube from eBay. But from what research I have done the shield is important...

I bought an old kenwood ts-520 at a local ham fest, was told it was working. Got it home started messing with discovered it had no rf out put. And that the driver tube was completely missing. If anyone has any junk kenwood hybrids or parts laying around, I will gladly buy the tube heat shield...

I have the one you linked, I bought it from Amazon a few months ago. I use it with a magnet mount Wilson 1000 on the roof of my truck. It’s able to tune the phone part of 12 meters to 2:1 swr. And then pretty much the whole phone part of the 10meters to 1.5-1. It’s small and seems to work well...

I have one that I use mobile, with my qt40 in my truck on 10 and 12 meters. I have it wired to 12v cigarette lighter plug. It seems to work good. I have only owned it for a little over two months.

I don’t have a schematic, maybe somebody here has one. This radio is a single conversion uniden chassis. Pc-385 board. The board in these radios is extremely similar to a cobra 140 gtl, now obviously the controls on the front of the radio are different than a 140 gtl. But if you can find a...
