I just bought some new 455,1969 ,2312 and 2879 all made by HG. All are same as original and sold by a few different sources now. Just an FYI. I'm gonna build the same Lincoln board for my bad final 2510's I have laying around

With the Mosfets, the parts I fuss with is getting the gate voltage right. Normally I make a divider off an 8 volt TX source for 3.8 volts and the rest is just fine tuning the surrounding impedances, which normally is a few hundred picofarads here or there. In the 29's I've done, I never add any...

Take what you need , I've used bits and pieces for my Madison projects, tried to piece together a few schematics on one to try make it easier for myself. Hope this helps. Also the Simpson Bengal MKIII uses the same board

If its a 2 piece , he could just ship the RF deck.

Heart of the SP1a is the NE571 compander.

Repositioning interface for inertia navigation system. A/D converter had some hung bits. Turned out to be the clock input was bad.

Just sent my Chipswitched Lincoln to Roger. He had a few in front of mine

I don't know if the CD version schematics are similar to the DX and oldschool orange display version. I do know that the issue was most likely on the CPU PCB, the tech probably wrote up the wrong PN's

Wrong schematic bro, C14 and R13 on that schematic affects the receive. CPU PCB doesn't reflect the same part numbers.

Was watching one of those silly super duper cobra videos. The solder slinger was mentioning that the light rings were going for $17 on ebay. Educate yourself consumers, $5 from Eric over at Palomar aka EKL Imports. Just doing my weekly good deed and staying away from these recent Return from the...

Talk about resurrecting from the dead.

Technology hasn’t changed much in the basic circuits of the radio. That radio has tons of mods for it. Most shops should be able to help you

The new president/Uniden radios pale in comparison to the 2510. I have a new to me Lincoln II and it is now where near a 2510 or Lincoln I own.

Works good. When tuning and adjusting the lengths, just know what makes sense wont work. I've been building wire Moxons for over 10 years now and what works for that wont work for this tube type. Antenna hears and talks just fine. I have it on a 50ft pushpole at 29ft. Front to back is pretty...

Do yourself a favor and get the 1895 15 meter and shrink down. I got mine tuned for 27.2050.

Wouldn’t the 7808 regulate the input and maintain the 8v no matter what? Maybe I’m missing something , please help me.

Nice work bro, I like the isolation board too. I built a few "Ibox" boxes. Your board is nice and compact. I get the cheap TM018's. Id buy a few of your boards, each on definitely solve lots of problems
