10-1, can you 10-9 but in English, por favor?
Tuning an antenna length in order to match a frequency range. This is to improve performance for transmission and receive but more importantly to reduce feedback and heat build up in componentry. Most antennas are sold and bought to connect to specific radio frequencies. Many of these have some simple mechanism to adjust length to more closely match a particular frequency that one may choose and to compensate a little for less than ideal mounting. In the simplest form of antenna length is a fundamental fraction of a wave length. From our school day physics, we know the speed of light, we know the wave length of transmission we calculate the length of Aerial. This gives an approximate starting length. By attaching a SWAR Meter the length can be micro adjusted by cutting off excess or trimmed by adjustment if buying a commercial Arial.
In the past CB radio was not legal, then it became legal with a licence for a set frequency range and power and was regulated or suppossed to be. Power max was 4watts, probably still is. Some people modified transmission power with amplifiers others by using better or bigger aerials, perhaps using a better fundamental wave length fraction. At home, in a base station some might use quite long simple aerials 1/4 wave, 1/2 wave 5/8 wave and 7/8 wave. Also, one can buy or make directional beams which can dramatically increas db gain. Some very elaborate and very large a bit like giant old fashioned FM Aerials. All mostly all too long for vehicle use particularly cars. In compensation aerials sold to car owner had coils added to short steel bendy rods. They came or come in all sorts of fancy arrangements and packages all claiming to have greater gain than is perhaps really obtainable. I had ex military vehicles all designed for radio.. A LR 101FC is about a similar size as a T6. Mine allready had mountings for a longish military thin tubular whip.. All I had to do was match its length for a new frequency. All a long time ago but I think somewhere in the order of 9ft. It seemed to have a much better range than most friends commercial offering. Coils that usually are at the bottom of an aerial but can be some where in the middle also, may approximate length but rarely match the performance of the real thing.
I never used the numerical code for conversation. So I would just ask for someone a proximate place, not their 20 for instance. I did once have a friend however who was formally a ships radio operator. He had all sorts of rigs at home including CB. Mostly all illegal, in terms of power and frequency. He could also use Ametour Radio Etequet or numerical code slang better than one might have seen on American trucking films. He also had amazing timing and could cut into any 2 way conversation, he just always knew when someone would stop keying and before the correspondent could reply he could cut in. A very difficult thing for ordinary mortals to consistently achieve.
I was based at Addenbrooks for a while and he would call me up on occasion when he new I was on the way home. He would often mimic a famous person or pretend to be somewhere unlikely. He was a huge joker. On one occasion he pretended to be in a Hercules Transporter that was having trouble he was in the loading bay and describing what he could see. People from all over Cambridgeshire where braking in trying to guess his situation or giving advice that the could easily change course for marshals airport which was use by the military. He would chop his power output and pull the mike away and add distortion to give realism. On another occasion, he pretended to be the Pope calling from the Vatican City. Sorry I am not in the least religious but do not intend to insult anyone. He spoke in pigeon English/Italian and used Amateur Radio Eticate. He explained that he was using (skip) atmopheric conditions known to enhance long range radio. That Ameteur and CB radio was his hoby and that when he had a few momments would broadcast. When he first anounced himself he did not first state he was the Pope or holy farther, rather using an Italian name El something or other. It was all really meant to wind up a mtual freind who had only recently bought a CB and was very poor or clumbsy with its use. My other friend despearatly tried in vane to call up the pope in a very long winded over eleberate way. He tried and tried callining ot El what ever I forget now. My other friend asked was his CB gear not good enough. this pope fello contacted me again and again using my call sighn but no other. Others too started to call the "pope" by code might have been El Duto or something similar up but without success some obviously using burners/Amlipiers all without succsess. The pope fello eventulally faded away with many callers including my other friend kept trying to reach him. It was really such a hoot. i had started a landrover Club in Cambridge and it was the talk in that. Of course they by then new the truth but not number 2 freind who was in absolut awe. The popes call sighn was El something and friend 2 was asking me during the CB conversation do you realise who you are talking with he was absolutly exstatic. He was a bit religious. He never gained the truth, just a bit puzzled by my apaent blazay attitude about the superior quality of my CB gear and the ordinary way i referere to my suposedly fortuitous conversation with the "Holly Farther" and at such incredable range
All of this was well over 30 odd years ago so Ican not reacall the proper call sighns one freind such a constant joker and the other so serious. Both such a masive personality difference to the other. I did however on one occasion to perform my own radio deception foolary over in Wales but that is another story.
