seeing this post was originally about repairing a radio I thought I would ask another question.
this is TOO LONG OF A POST..... don't bother to read it unless you too have and like the TRC 207 handheld CB radio. or you really have no life.
you have been warned.
I had a couple Radio Shack handhelds when I was a kid that I wanted to talk all around the town in the worst way...... I worked all summer mowing lawns, waxing cars, weeding gardens..... whatever I could, to buy a Radio Shack handheld CB.. it was $19.99..... turned out it was a one watt input 1/2 watt output with one channel 14 crystal in it..... I couldn't talk to anyone!!!... so the next summer I worked all year again and bought the two watt radio shack handheld ( one watt output) for $29.99 and again could not talk to anyone!!!
the next year I really busted my ass worked night and day wasted the whole summer just to get a handheld CB.... I got the 3 watt TRC handheld ( 1.5 watts output ) one channel 14 crystal in it..... it was $39.99 a HUGE AMOUNT for a teenager back then. all three of these radio's had 4 feet tall antenna's........ and again I could not get anyone.... I figured being stuck on channel 14 didn't help.
my Mother had her brother the truck driver come over so I could talk to him and make sure it worked. he told me I really needed a 4 watt output radio and 40 channels to find someone to talk with... he drove down our long 900 foot farm driveway to get to the main street..... I was able to talk to him until he got about 100 feet from the main road!!!! so I got about 800 feet!!!!
so I said THAT"S IT!!!! no more stupid radios!!! ( but I still had the radio bug in me)
when I got a real job at minimum wage $3.25 an hour ( a 40 hour, weeks pay after taxes was about $70.00.... I went to Radio Shack and got a 4 watt handheld CB that had 40 channels!!! it was $99.99
I figured I got a real deal radio now!
and I would be able to talk around the town... NOPE! ... I was lucky to get a 1/2 mile out of it... it had a brand new to Radio Shack, fancy Dancy, new innovation the new rubber ducky antenna!!!! Radio Shack made a big deal about this new type antenna back then.
well I learned the Rubber Ducky SUCKED! I missed the telescoping antenna's
so for the next 35 years I tried to get a different longer antenna for it.
it is only a one wire antenna????? most antenna's have two wires... but in the picture you can see it is only solid stud.... I tried to get a bolt that would go into that hole.. it's an 8MM but it's got a weird thread and NOTHING screws into it... ( I've spent a lot of time at hardware stores) I thought I could somehow bolt a telescoping antenna on it.... I have read articles on it for years about other people looking for some kind of adapter to allow a better antenna.... but it seems TRC made this very different...... most antenna's are 50 Ohms ... not this one??? so Radio Shack made sure no one would use anything other than their antenna on it. ........ many people have tried other ways of getting a different antenna on the connection and it usually burns out the radio???
it has become my obsession I have tried everything... TRUST ME they do not make any kind of adapter for it... I have a Maxon CB that has a similar antenna, but they do make an adapter for that one, and I have it, it's a Motorola MX to BNC Antenna adapter for Motorola Maxon ICOM Radios... but it doesn't come close to fitting the TRC 207..... the Maxon has two wires to it, so the adapter connects in two places,
the center hole and the outer ring.... my TRC 207 is all one piece.
so I opened up my TRC 207 today after 35 years and was going to change the weird fitting for a BNC connector.... PLENTY OF ROOM!!!!! but the Auxiliary antenna connector in the side, is 50 ohms and is wired to a different part of the board? ... the one single wire that goes to the weird connector has a lot of electronic pieces in line with it and goes to a completely different part of the board?
I was going to cut that out and solder to the two wires to the Auxiliary antenna connection on the board... but I found using my multimeter that when you plug an Auxiliary antenna jack into it.... it disconnects the weird fitting....... well, if I solder it on the board, it will not be disconnecting all that weird wiring for the weird antenna connection... meaning both would be used at the same time??? probably causing trouble.
so I made a piece that I can attach to the side of the radio, and plug into the Auxiliary port and it allows me to use the GREAT HYS 51 inch telescoping antenna... I find I get over 4 miles range with that great antenna.... looks ugly and not what I wanted... but if it works and I can get 4 miles range I'll play with it..... then another day I may buy a cheap TRC 207 off E-bay to solder a BNC connector on and if it burns it out.... it was only an experiment any way..... I don't want to experiment on the radio that I had to work two weeks scrubbing floors to get... as it works really nice! I always like how well it receives and my voice always sounds clean and clear on it... it also shuts off the display to save battery life after 3 seconds... I always thought it was a nice radio, if it wasn't for that damn duck antenna.
so any thoughts about just cutting out the old antenna wiring ( leaving it connected to the board) and soldering to the board where the Auxiliary antenna connector is????
