The 101ZD is back, but with another problem this time. Support us on Patreon; / theradioshop Contact Information; gokarters.com/smf/index.php?to... Discuss this on my website;
I have this radio that was my father's. He got it brand new and used it for many years before his passing. He asked me to take it just before his passing. I just got my ticket, finally, and will get it out of storage and check it over. Thanks for the really nice videos. I'll keep watching.
Buddy thanks for the great work you do for all us youtube watchers. Hope all is well for you and your family during this hurricane and flood season. We have had a lot of rain in toronto on canada up here, but not as much as you guys have had down there. I say again thanks for your videos you are a genius.
Appreciate the kind comment Henry. Hope the storms are over for now. We still getting a lot of rain. Even today so did not mow the grass lol. Thanks for stopping in.
Great job Buddy. I love watching over your shoulder as you sneak up on the problems. Thank you for sharing them with us. I know what you mean about the wife wanting the kitchen remodeled. My wife has been after me for the same thing. I've been using the "lack of money" excuse but that will come to a halt right after the end of the year LOL. Our kitchen has been painted hot pink (by the previous owner). Wishing you good luck with your remodel job. Remember to stay safe. 73 DE K7RMJ Frank
Thanks for riding along Frank. Kitchen is about half done and came down with a bad cold. Got the new appliances today. Still have to put the floor covering down, cabinet doors, and paint. Take care my friend.
Another good tip to keep in mind for future reference. I've been using that Hockok 800 for years Buddy. Great tester and has never given me a problem. I should probably look into doing a refurb on it. I'll wait for your video to inspire me. Glad all those hurricanes didn't cause you any flooding. I was thinking about that the other day. 73 Doug.
Another excellent video. Thank-you. You are very patient and thorough. I am looking forward to the 2213a oscilloscope since that is the scope I have on my desk.
Nicely done Buddy, excellent video. I learn something every time I tune in. Looking forward to the up coming repairs. Good luck on the kitchen remodeling. Oh, BTW, I have a 800 that is a parts unit, just let me know if I can help with parts. Joel
Learned a lot from watching through all your videos Buddy. Thanks for taking the time to do them. Just bought myself an IFR 1200S to help repair a couple of Yaseu FT-480R's. Fun times ahead.
The Radio Shop I've watched all your videos and seen them both. I bet the Super S is pretty expensive, I bought my S for what I think was a very good price and it's in very good condition. The idea was to start doing some repairs for other people in time. I'll get my FT-480's going first though. I've had fun with the PLL in the first one so far!
Thanks again Buddy, love looking over the master's shoulder. A local antique dealer has that model Hickock, and I can get one for a good deal, but needs some work. Would love to get it and play along at home :)
Nothing like paying for a repair twice because someone else didn't know what they were doing or did and took a short cut and charged the poor guy for full repair. Good job doing a proper repair.
Good on ya for doing the job the right way! I wonder how many techs would just hit that terminal with a bit of flux and solder and call it done? I knew you wouldn't, and I bet Mike and Peter certainly wouldn't either. A fair bit more work to do it properly, but well worth it.
Got everything ripped out last week end. Replaced the sub flooring over 80% of the kitchen. Got the new cabinets built and installed. Bought a new stove and microwave. Have to make the doors for the lower new cabinets and also the uppers. Start the painting this week then install the new floor covering. So about half done.
I see this on this radio when hams try and adjust the display/Vfo to try and shift up to work the MARS freqs. They often just screw up the output or dial reading.
Its surprising how many times a repair is needed due to someone else work! I haven't been able to upload as many videos lately due to my workload either, I have a stack of radios that are either half done, or waiting for me to do them... will be glad once I can get back to them! at the moment I am trying to fix a Fluke 5200A AC Calibrator, which is turning into a big job. I still need to finish my channel conversion board for the Cobra 148, it is so close to being finished, I just need to re-write some of the code for the handling of the bands, but time is against me at the moment.
Another great video. I just picked up a 101zd mk2 that has issues with the tuner/display as I am not seeing any change in my frequency as I rotate the tuner control.
Hi, looking for a pointer if you have time? Ft101zd was connected to 230v when it was set to 100v. It blew fuse and now doesnt light up!! Any pointers? Thank you
A shame someone tried to shortcut installing the trimmer cap. Just shows why doing it right the first time is so important. Hmm, is that black case tube tester a Triplett 3444? Case looks about the correct size. If it is that's one of the best "portable" laboratory mutual conductance testers ever made.
B&K 707 Dyno-Jet. Belongs to one of the viewers. Yep if it was done right the first time wee would not had any issues when I worked on it the first time. Never know what lies beneath the covers on these lol.
Nice job on the repair. I have a Mark III Yaesu FT-101ZD that on occasion when I switch to CW or AM modes then return to SSB. The display shows 4 KHz lower than the actual frequency that the VFO is producing. A back and forth on the Mode Switch generally will cause the VFO Display to return to a correct reading. Is this a common issue with these units ?
Sorry Buddy in thumbs up section I am an odd number. We know your very busy try to take your time ( Hurry up ) LOL... Maybe you could start a school of Electronics. Just a thought. Great video my Friend.... Angelo.
Thanks Buddy for the video, looks like your a victim of your own success! Try and spend some time for your self as well Buddy, hope your health problems are better. Best regards Carl.
Great video, well presented. I enjoy watching and following your very methodical troubleshooting technique. It's exactly the way I was taught in Tech School. Too many RU-vid videos of guys "repairing" are just hack-jobs shot-gunning till they stumble across the fix. Thank you.
Thanks for the very nice comment. I agree so many are just grasping at ideas till they get it right. I am self taught and never been to any school myself.
Fantastic tutorial thank you. I have the ZD mk 2 which has a different counter/display board to the one depicted here. (no DIP switches). My rig has a completely blank display. Does anybody know if the 7 segment LED devices are common anode or common cathode? (and which is the common pin) please? The only service manual I have if for the Mark 1 version. I intend to check the 7segment devices (with a 9V pp3 battery and current limiting resistor) I thought I would work back from the display onto the board and check the FET, 5V lines etc.
@@TheRadioShop For the record it turned out to be the LSI chip fitted to the Mark 2 versions. I was lucky - I founda replacement on ebay which works fine. But there is another solution - A Japanese amateur has devised a drop in replacent chip based on a a PIC which replicates all the funnctions of the LSI chip. I have one of these but didn't need to fit it as the Ebay one worked perfectly. If anyone wants details of the Japanese replacement chip leave a message here...
Hello buddy !!! good to see you again !!! I thought you would have to dremel those capacitor leads ! Once again a good show !! --------- KC2UVN ----------- John A Bellas

First which version do you have? there are several. Does the radio work and just the display bad? Also there are many things that can cause this issue. This uses TTL and lots of things from bad connections to failed IC's. Can even be communications faults causing the issue.
