Nice repair and overview Buddy handy if you can't have an antenna farm in the yard. Always a pleasure to see my Grail rig in use also (Kenwood TS-2000) one of these days , but my TS-520s will have to suffice for now.
More fun stuff.. I bought another unit as a spare on sale for $46 which I noticed had a complete redesign of the PCB relative to the unit shown in this video. Looks to be substantially improved and with some opaque FMD (who?) SOIC microcontroller directly on the board. This particular unit has an AC mains SPST switch which definitely seemed like an improvement though obviously an afterthought as the rear was drilled out to accept a round 20mm switch. Well until you realize the switch opens the neutral not the mains hot line. This is just a copy of the original DIN connector (wrong choice of gender) design where when hot air or iron is disconnected you have 24VAC or 120/240VAC sitting on those pins to accidentally meet the user. So rather than move the SPST on the neutral to hot I picked up the same switch in a DPST version and rewired to switch both AC mains. Another thing is those "couldn't possibly be made cheaper" screws threading into the ABS case were starting to stress discolor it which IME eventually fractures the ABS. I drilled out the holes and epoxied in brass insert nut to mate with M3 screws. I suppose that should be done for the front PCB and transformer mounting as well but I stopped with the case alone.
Nice video. I fixed one a while ago where the bottom half of the antenna was full of water. The motor was rusted past repairing it so I bought a similar replacement motor on eBay and swapped it out. I then soaked all the rusted parts in vinegar overnight and turned out great. The rest of the antenna just got a good cleaning since it was still in pretty good shape half way up. It works like a champ now.
"Fix it up, wear it out, make it do, or do without" I sure appreciate your skill set, Buddy! The "Dyno Cams" sticker on your toolbox reminded me of my Karting days 😊 We're kinda cut from the same stock...
Excellent, Buddy. Nice repair job. I had a Webster Band Spanner on the truck for a while. I thought the Tarheel was basically a copy of the old Band Spanner until I watched your video. Thanks for sharing it with us. 73 de K7RMJ Frank
Nice video Buddy, I always wanted one of those but the cost wow Great mobile antenna if you have room to mount it. Local ham here has one on his car roof with a magnetic mount that has 3 magnets. Just hope he doesn't drive with it on.
You remind me of Mr. Pete! Or Keith Rucker! Before you got there, I was thinking to myself he needs to bore that out and put in a bronze bushing and thread it. That's exactly what you did. And I learned that just from watching RU-vid videos. I am not a machinist but I love watching machinist videos.
I watch both of those guys, along with Abom, Blondihacks, This Old Tony and a few more. I could have made a new piece but thought it be simpler to repair that one.
Uggg, those antennas. It's always corrosion that kills them. May you and your family have a happy and safe 4th of July. p.s. A very high Q on that antenna. 😳
Thank God all my antennae are all fixed length. I know of several guys who run those Tarheel antennae. Now that's a great fix for that known problem with the Tarheel. That should be a permanent fix. Only mobile I talk is 2 meter with a small dual band, mag mount on the SUV with a Yaesu hand held & 20 watt amp. Cheers & 73 from K9POW in eastern TN
Thanks my friend. If I ever find me a small HF rig I may go back to some mobile work. But it may be useless to do since my longest trips mobile is only 15 minutes at a time these days.
As always your videos are great. I could really use the pro scope. My old Tektronix 2213a has almost completely died. The trace function went out and I'm down to guessing at the calibration. Take care everyone and have a safe 4th of July.
I literally took mine apart as you did and followed your guidance step by step. This sort of video is very handy to use as a guide. I’d love to watch you recap the capacitors and see how you do it.
Hi Radio Shop guy. I hope you had the chance to fix this monster. Just some tips to you. This thing is from the 60's. Means all switching is mechanical, using relays etc. I would recommend to clean up carefully every single relay is on there. In the power supply there are some, in the RF lines and in the display unit are like 10 of them. Several years of inactivity and inadequate storage are causing corrosion in contacts. It's just the first thing I always do to vintage electronics.
I have 3 or 4. A early serial 101 no letter that is the best working one ive seen. Ive got a 101b but letters are flaking off. A 101e missing 10m xtals. A 101e with some weird demodulator mixer board. I have a original silver trim 101fv no B letter vfo. Probably pretty rare as ive never seen one ever before. Have the yo100 but cant figure out why theres voltage on the chasis. The yc601 in your video looks odd like a inbetween version...love these but i prefer the ft901dm or 101zd or ft102 for tube hybrids. This station looks super clean
Thanks for this informative video about the Sencore CB42 CB Analyzer. The concept at the time was to provide the servicing technician of a CB radio to hook up the essential cables to the product, and then conduct troubleshooting tests from the RF input to the power transmitter output to the antenna, with some twists of the appropriate dials. Such was called a "systems approach" for troubleshooting for finding the problem fast, rather than the parameter measurement techniques of Tektronix and Hewlett-Packard instruments of the time. I wrote the operations and some of the maintenance portions of the CB42 manual.
Beautiful, Very envious, I collected a 101ZD Mark 3 in Mint Condition, Sadly no Scope which is on my Wish List. I do not normally post as you are obviously busy, but I do love your posts, Great Work Man. 73
Love the 101EE that was my first radio I bought one that needs a lot of work eventually get it done but will be referring to your 101 videos to make sure I don't miss anything :)
Big and chunky, easy to use unlike todays sets which are wonderful but too small to be useable with their tiny little switches and multi function buttons. My favourite receiver is the old Sanyo RP8880 from 1978, so easy to use , read and understand.
Yes I have the same set up here and worked on the FT-101E. Took me a while to get all the accessories but was worth it. Love the radio and should use it more than i do. To many transceivers and a little radio shack makes for not easy access to them. Thanks for sharing and will be following the next FT-101 videos.
