Re: The Hum-Less 2B
They are good fun! I still need to pair mine up with an available transmitter. For those of you who don¡¯t want to spend big bucks on the can cap, there are also PCB¡¯s available that attach to the

Re: T4XB/R4B Transceive problem
Okay, final report. Tonight I got on with the Friday night 75 meter group and tried her out. I spent quite a bit of time switching between lower and upper and even switching mic¡¯s. The verdict:

Re: TR-4C Problems with 28.0 and 28.5 bands
All tubes tested good except for V2 and V17. I replaced both of them with 'new' ones I got from vacuumtubes.com. 73, Dave KD5FX

Re: TR-4C Problems with 28.0 and 28.5 bands
Yes, I tweaked the L2. and the other 2 also according to that section of the manual. I test the 6EA8 and it's OK too. 73, Dave KD5FX

Re: TR-4C Problems with 28.0 and 28.5 bands
I borrowed a friend's Xtal tester today and all 3 10 meter xtals test OK on it. Just to compare, I also tested the 15 meter Xtal and they all showed about the same amount on the test meter. So I think

The Hum-Less 2B
I roasted my Drake 2B filter cap 20+ years ago by putting a manual on top of the radio and the resulting heat dried out the electrolytic. HUMMMM.... I've been "meaning to" fix this dude for a long

Re: Not all problems are Single-point Failures...
I had heard about some strange keying issues due to leaky diodes. I seem to remember either D7 or D9 causing trouble. With the two bad diodes, when you plug in a key and select CW, the relay pulls in

Not all problems are Single-point Failures...
I figured that I'd pass this one along today, as I wind up fixing a T-4XB that had a number of problems. It got sent to me because the owner has having trouble aligning it and got down a rabbit-hole.

Re: Drake repair service
Can you please share what you learn and what's quoted as their hourly rate, please? I have a TR-3 that's been giving a buddy fits (he can usually fix almost anything). It's been on and off his bench

Re: TR-4C Problems with 28.0 and 28.5 bands
Good point, Marcus, and very easy to check. Try swapping the two 6EA8¡¯s if you don¡¯t have a spare. Steve Wedge, W1ES Time flies like an arrow. Fruit flies like a banana.

Re: TR-4C Problems with 28.0 and 28.5 bands
Did you tried to tweak L2? If not yet, give a try. Despite the instructions to set it up at 29.1MHz position, after that manual recommends that the level produced at the test point
