Awseome! I'm glad you got it up and running. Another prodigal child returns to the flock. I feel your pain, my local noise floor has increased dramatically in recent years. On 80m particularly, S-9+

Jim, I added a 68 R in series with the existing R2303 (which was 47 R). That brought the driver standing current down to about 220 mA, which seems reasonable to me and is more in line with your note.

The 11volts comes from a big wirewound dropping resistor from the 150V.? See the schematic and look for the resistor. Hopefully they didn't remove it for the previous mods. 73, Gary WB6OGD

It’s cool what we found on the various 2-B’s we worked on last year. I had two other ones besides that horrorshow. One of the others sounded obviously like the PBT needed adjustment, so I finally

Hmmm. On two different transmitters, with a diverse collection of mics… Did you do alignments on both? I’m trying to find a common thread. How is the carrier balance? I set carrier balance with an

It’s a TR-4. Yeah, I do this, too. Don’t feel bad, Mark :-) Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a banana. Sent from [Proton Mail](https://proton.me/mail/home) for iOS

Dean - You have done an awesome restoration on your 2B; super congratulations on what you have done.? The front panel looks just like Drake made it.....minus the original knobs....however, yours

Yes Steve, the one with the glue inside for lubrication, hi hi... It had to come apart for that anyway. 73, Gary WB6OGD

Look back at my post #72582 I just checked, they still are selling the last 2 knobs!?? I thought I bought the last two!! Not cheap but available.? Keep the guitar guys from buying them up. 73, Gary

I will put up some pictures of my setup and what it looks like on my other radios later tonight when i get home or tomorrow morning. Thanks for the help. Mark [email protected]> wrote:

Joel, I would look again for the pot. All R4B's have it. Even the earlier R4A and R4's. The procedure you want to follow is paragraph 6.4.9 then look at Figure 13 and you will see at the bottom the

Both. I have listened on a couple different radios I have and have seen the signal on the waterfall on those radios. I have also gotten a report back from another Ham who said there was to much

I bought a restorable 2B with 2AC off Craigslist last year from a fellow ham in Florida for $50 plus shipping.? It did not require any unusual work to get it going.? I replaced a couple of weak

Hi I would suggest to purchase the CDs from K0OAH. These are invaluable if you work on these machines. These, plus the circuit diagram will provide you the answer. k4oah@... I could open my

Thanks for your response, where is that 11vdc point? I can't find it. thanks, again

Hi Coincidentally I replaced the PTO of my R-4C yesterday. The red-white wire from the PTO is for the +11 Volt supply of the PTO. 73 Rob Verstuurd vanaf mijn iPhone

Hello, I am restoring a tr4cw, with some problems, at some point they made a modification to install a dds, I have noticed that there is a loose white/red cable that comes from the pto, I can't see

Check Optical Interrupter Bias, section 5-5.4, and Optical Interrupter Mechanical Adjustment 5-5.d. Note that a mechanical VTVM or VOM is specified for alignments. If all that is good check the

The RV-75 I am working on, only decrements it will not increment. Either way I turn it, it only goes down in freq. Any clues are most helpful.
