Did you check that there is an insulting strip loin top of the PTO mechanism? There is a very close fit between the bottom of the DR7 solder and the grounded metal below the DR7 just below the display

Billy: Indeed, the MN-2700 might be a better choice for 160m than trying to convert an MN-2000.? 160M coverage is already built into the 2700. It won't quite match your 4-line for sure.....but

Hi Billy I would think it near impossible to add 160 to the MN 2000. It looks like a high Q circuit and I read somewhere that it performs best when using antennas of near resonance and is tetchy on

It looks like you have an aftermarket LED board from DF4NW. Nice! However that suggests that someone botched the install and gave up on it. The display is strobed. One set of segment drivers drives

I seem to remember seeing a 160 mod a long time ago. Unfortunately, it involved drilling holes. At a minimum, it would involve adding inductance and fixed capacitors whilst using the bandswitch in the

Thanks Steve. Both digit one and two are missing the two segments I think.. You may be right about the soldering, it was a mess so I re did it . Will check again? and also look at the drivers. I am

Put up a 160 antenna and use tuner on 80-10 ! 73s Byron AC9PA

The second digit is missing two segments. It looks like a display or driver issue to me (assuming the etches and soldering are okay). I can’t remember if the display drivers are open collector or

Hi Everyone, hope you are safe and well. I have fitted the rebuilt DR7 and the up/down and jumper works just fine. The first two digits seen to be missing the same part of the display which is a

Hello All Looking for a final cage for my T-4Xb I have reworked the Chassis and need the Final Cage Thanks Bob. kQ2Q. Danielsville GA

My apologies, T-4XB not TX4B

Good day! Wondering if anyone has a lead on TX4B and PS to pair with my recently acquired R4B.? I have some AM plate modulated experience, but this would be my first tube final SSB venture. Also, any

Cowan, The next step would be, with no power to radio, use an ohmmeter across the primary of the audio output transformer. If it's good, you should hear a "pop" in the speaker when you touch the

I bought a used Drake R-4B out of a garage and a previous owner etched his callsign and social security number in the back of the radio. I was able to track him down and found out he had been a

The decals will be useful for anyone building up one of the DDS FS4 replacements. They help you find the correct peak for the preselector. A few years ago I had a guy lined up to do some nice

Another comment, there was a common mod for the Heathkit VTVMs propagated by those who didn't know any better that moved the probe resistor to the inside of the unit on the function switch. I guess

Here's a couple of good articles I found from RCA on VTVM use in the ham shack: http://n4trb.com/AmateurRadio/RCA_Ham_Tips/issues/rcahamtips1704.pdf

It was called “Operation Identification” and was promoted by local police departments back in the 1970’s. Lots of people — including my dad — engraved their SSN’s on many possessions. 73,
