General Radiotelephone license?
« on: August 03, 2009, 07:35:09 PM »
A hundred years ago, I had a 1st class FCC license, then the rules changed and I was issued a General Radiotelephone operator license (General Radiotelephone Certificate).  This started life as a permit to operate and repair any broadcast radio or Television transmitting equipment with the exception of shipboard radar, I really don't know if this is of any use now.  Anyone know about the commercial stuff now?  Larry

yep still has uses trotter. do a search for w5yi. i think you can find some info on commercial  licenseing there. i hope i have not handed you a bum steer trotter but w5yi did have commerical studyguides listed on thier site. it has been a few years since i visited there. the fcc will also have info. i take it you once worked in the broadcast field? i am always on the lokkout for parts, if you have any good rf transmitter parts you can part with ket me know please! if you know anyone working in the field that mite have acess to tube type broadcast gear drop a line also.many stations are going solid state nowadays and disposing of the old tube gear. hope i have helped trotter! 73's

lord awmighty trotter!! is that 5 kw or 10 kw tube?? jeez i was thinking and hoping along the the lines of maybe a 4-1000 modulator tube!! i built a big amp once. don't want no monster amps again. i am working on a amp again. it is just using a couple of 350 watt plate disp. russian pulse tubes. those should give me plenty. hey 4b here is a tube for a california kilowatt!!! thanks for the offer trotter i would just go and  build something i don't need with that tube!!! i could use a transformer tho. about a 2 kva. core. i can rewind transformers so even a toasted one would be nice. thanks again trotter!! did you check out w5yi? they did have commercial study guides and a list of testing sites by state. i hope i have helped you out some!! 73's

I'll take a look and see what they say.  I am retired from Boeing now, spent a lot of years in the broadcast field however.  I may have a 500 watt driver tube around some place, I will look, haven't seen it for years however.  Larry

larry, that would be great! what is the tube you have pictured? that would make a monster amp! i  am in the process of building a small amp now. i have got about 2/3 of the parts i need .i am going to build the plate supply in a seprate enclosure where it can be used for other amps as well. i have filter caps and and 25 amp 1200 volt stud mount diodes. i still have to come up with some bleeders. this getting old and crippeled stuff is for the birds!!! i will just keep slugging away till i get something done!! ihave a 55 volt @36 amp constant duty transformer that i am rewinding. i sure hate to sacrifice that transformer. it would make a darn good solid state amp supply.if you know where i mite find a 1.8 to 2 kva. transfoemer core i sure would be tickeled!!! wishing you all the best! 73's

hey trotter!! when you get old and crippeled up you make do with what you can get!! mercury vapor rectifers are darn dear  now a days! tubes in general are darn dear to come by. gone are the days of eimac, and penta. they are both somewhat still in business selling import stuff. no more 20,000 hour decent american made tubes. this'uns gonna be a sissy kw. amp. that is all i need to contend with!! i am slowly making some progress. it sure ain't going like it did when i was young and healthy!!! glad you are stopping by!! it is good to hear from you. now i got some one to question!!!!!73's

Well, I did a lot of AM directional stations in my youth, then some FM's, a little bit of pager and mobile phone service in the 80's, then point to point microwave, a little stint with a microwave R&D lab, a U TV station with vapour cooled Klystrons and some R&D with BWO's and Magratrons.  Later some antenna design for some black programs in the 90's and now I am retired.  Along the way I worked for HP in the Spectrum Analizer division, It has been an interesting life, but I don't miss hiking to the microwave sights in the snow to get the generator running or climbing towers in the rain.  Now, some times, I feel like I must have sat in front of some open wave guide just a little too long.   ;) Almost forgot about Viet Nam, that fell some place in there.  Larry

 Hey trotterlg:  You're way over my head in your radio and electronics background, but I was in Nam.   Now that was an experience for me.    Through some unusual circumstances I ended up over there with Intelligence in a small elite group of AirForce, Marines, and Army guys composed of Recon, Radio, Operations, Personnel, and Intel fields.   We were actually an experimental group of 13 misfits working with some of the smartest men I've ever known, and crazy fighter and test pilots, but we made history by composing the ground work for the most sophisticated combat coordination system in the world.  What a hype that was.  

BTW we have the same initials lg.  73's Larry
