My Tarheel 200hp quit working 11 years ago. I hit the up button and antenna went part way up and quit. I was told there should be a capisitor on motor that fails. I have been searching online for 11 years and couldn't find ANYTHING about repairing this rascal. THANK YOU FOR RECORDING THIS . Now I at least see how it comes apart so I can look for this failing cap.

We used to make these panels, not sure if this is anodized or not. The worst thing you can do is clean them like this, the lettering got tattered and the rough etched surface under the lettering is breaking through, compare 3:47 to 10:52... NEVER use a toothbrush or rag, or anything that can get down into the etch unless you are stripping it completely, the panel has a vertical grain, go with the grain. Use a wet sanding block on a piece of wood with 300 or 400 grit WITH the grain, if it is anodized you can tell, it will be hard and slick, go easy on it either way, if the paint is dirty in the letters you can gently clean them with mild non abrasive soap and a toothbrush first, or strip it and repaint them, then place the panel on a flat piece of wood and wet sand all the paint off in the same manner, use a clear coat if you desire. It will look better than new. My works hang all over the world, on machines, under water to mark reefs, docks, panels for ships, some in famous actors homes, football players...big wigs, small wigs, universities, hospitals, businesses of all sorts,....but I got no credit.

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.

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.
