I have an original Motorola low band handie-talkie FHTR1DH, I acquired back around 1968 when I was still in college.? At the time I had new xtals made for 52.525MHz from International Crystal (SK).? I operated it for a time until the batteries discharged.? It has been sitting in a box or on a shelf for the last 55 years and I all of a sudden got a bug to get it running again after reading W0RW's article in CQ Magazine recently and Paul graciously let me borrow the manual for it. After a number of moves around various states since college and the Air Force, I have lost the antenna for the HT.? I checked all my junk piles and it is nowhere to be found.? According to the manual, the part no. is P-8563 and the loading coil is "pre-tuned and sealed at the factory to the exact operation frequency".? Does anyone out there happen to have one of these antennas or the loading coils, or know where I could get one before I start on an adventure of home brewing a new one?? Never mind the fact that I'm going to need to build new battery packs with with 20+ 9volt batteries. I would greatly appreciate any help.

It was not the same as the one for the Dispatcher style later pack sets, those had a more versatile antenna that was tunable. Those are also unobtainium. I suggest that a 1/4 wave at 52.525 is pretty short and you could just make a full-length whip and solder it into a PL-259. I have been wondering about using those little eBay Chinese buck converters that take voltages of around 6-12 Volts and step them up to 67.5, 134 or whatever. They are really cheap and efficient. However, they are RF noisy on the lower frequencies. I wonder how noisy they are at 52 MHz.

I knew that antenna was long gone but I thought I'd give a try to find one.? A 1/4 wave at that freq is around 54" which is not very practical to carry it around.? I think the original was around 43", and that extra 11' makes a difference.? I've got a few old CB whips around so I'll try a shorter one with a loading coil.? I actually used one of those cheap boost converters to go from 12v to 30v to fix an old Icom IC-228 which needed an internal 30v source.? ?There isn't any discernible noise on 2M so I may look into some of those.
