Mark, Just so you know, when the Vatican representative shows up, I have nominated you for sainthood.? :) Regards, Kirk, NT0Z My book, "Stealth Amateur Radio," is now available from

Jim, Thanks for catching the errors in the parent board pinout doc. No matter how many times a person rechecks something, a different pair of eyes can spot unseen errors. As I get time, I'll update

Yeah, I was doing the same thing. Fully-working is the best situation. Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a banana. Sent from [Proton Mail](https://proton.me/mail/home) for

Here we go. I think this was what I found. I was not actually searching for errors at the time and I neglected to make any notes. Tom's drawing is an amazing work. Buy the guy a beer (or two)! I can

Thank you Steve. It is a great satisfaction to have the L75 Amp working in all respects. To see how the readings matches the manual and now it is easier to take care of it by reading the Plate and

Nice work Mark! It sounds like you are bringing a poor abused child back to useful existence. Well worth the time and trouble. The band switch detent is pretty light on these. Is is the ball and leaf

What a job!!! Thanks for sharing your journey and good luck with the TX! I also brought back life to two ?junk TR7s“. (Yours sounds really terrible…) You learn a lot about the radio that way.

Hi to all in the group. Below some findings from my repair journey with a TR-7 that you may find interesting. A couple of years ago, I acquired a Drake 'job lot' on eBay. Until this week, the TR-7

I have an L-4B Amp. Love it!! The bulbs on my meters are starting to get dim. Want to replace them with LED's. Just inquiring if anyone has done this and is there any tricks that I need to know to add

Hi Rick, The TP114 test point should be a good place to get the frequency. This is to prevent loading on the oscillator. All I have got to go on is the schematic which isn’t a very good copy. It’s

Peter, I have downloaded the data sheets for the digital integrated circuits on the digital board and studied the ToO section of the manual until I can almost recite it verbatim. As I look at the

Not to worry! My memory is even shorter! Rick K8EZB

Rick: Duhhhh and you told me that! Memory is great....just really short. I'll crawl back under my rock now. Will peak out once in a while to find out how this ends though. 73 Peter VE7PS

Hi Mike. Looking quickly at the Offset Bd schematic, lines T, L, M, N should not be changing state in 140, 220 modes as these control the 5 Mhz offset for 440 Mhz. The 140, 220 and 10.7 Mhz (receiver

Peter, I have changed out all electrolytics in accordeance with a capacitor parts list provided by Jim. No Capar, mixed brands. Well ... yes, hopefully. All new caps tested before installing? for

Here is a photo of my RV-75 which is set for a TR7. So yours seems to be ok. Some where I have some notes on the position so will have to look. 73? Bob
