Okay, first off thanks for akl the good input. Having an automotive background i get a lot of the data, and as I figured.....the radio should definitely be setup with this amp. As always in my past as well as yours theres always the crowd that just plugs stuff in with no thought, and we all know...

Sorry, not good at typing on phone, old school fingers. Leap, youre right, and now i get the "pill" routine, im used to calling them power transistors, but they do look like pills, huh? Dont guess but what my guy did was just plug and play. So to use this for a stock cobra 25 means ill have to...

Ok, so let me back up one.....I assumed 2 pill due to the 2sets of jumpered whats(?). But now leapfrog and tallman appear to be right, single pill as a preamp. What exactly are the units with the jumpers? My bad about 2pill, im used to seeing transistors marked with #s. Please bear in mind, im...

Yeah, couldnt wait. 4 screws, move the front, cover slides off. Looks like 2"pills" jumpered. SD1446, 59V, 0130; no signs of corrosion or burning. Couldnt find #s or marks on the pills. Hope the pics come through ok.

Yeah, Ill try and get to it toute sweet, just got home from work, and Im beat. Looks to mee like the board slides out from the end...one piece case/heatsink? The timeframe that P&B was talking would be about right according to the info i got from my buddy. Never seen a linear this small before...

A buddy of mine just gave me this linear(?) and an rk56. Havent opened it up yet to check......look familiar to anyone? Any ideas as to what the preamp switch is for? Looks like a cobra power plug. Illl open it and send more pics later.

Hey mudduckmobile, including your wife in my prayers, real glad she's home and better. When my wife went thru breast cancer a few years ago it hit me hard how big a loss and empty a hole life could deal you.makes you "peak and tune" your outlook and attitude. Hope all is and goes well. Hang in...

Wow, a kubota tractor engine...who wudda thunk it. No wonder its hard for me to turn over when its cold! Cant rightly remember what year i got mine...guessing 78 or 9, mzybe 80- i had an antron 99 setup on my chimney with standoffs and my 148gtl. No clue what ever happened to the paper, lotsa...

That's pretty much what i figured from the little research ive done, thanks for all the input guys....figured it couldnt hurt to check up on it. Since uncle charlie wasnt pestering me for $ ya gotta figure its either long dead or obsolete!!!

Would it be fair to say that I should be using this call when talking ssb, not really looking to get involved in ham at this point

Hey W9CLL, how many years ago, and am i right about the amateur radii thing.....that wasnt for ham as well back then, was it?

Yup, have tried to do a little checking with uncle charlie....can find nothing. Guesd its like you say, keep using it. Undertaker- do you still use yours? I want to say it was for amateur radio use back when, but...."with age comes wisdom, closely followed by alzheimers"!#

For any of the .......old.....guys out there......back in the day I got a license and call letters from the (FCC????). My call letters were KBOD3800__never heard another word from them, am fairly certain this was for "cb", not for ham. Suprised i even remember em after all these years, can't...

MOGVZ..... nuthin for nuthin, has there been any tests or research done on different types of conductors in coax? Thinking in terms of spark plug wire technology, carbon with stranding, double shielding, etc. Not real knowledgeable, but seems a lot of concerns could be solved in this area...

Yup, copy all that. Since my background is automotive, esp driveability, electrical, and electronic controls im drawing on that base and using that to try and "keep up". No doubt theres a lot i need to learn about rf , ac trans, and so on.....but trying to geta step above your normal...

Its related to the wavelength of the frequency. When you read articles about making it the size of the antenna that is usually when talking about a compromise installation where you don't have sufficient room to run longer radials. www.k0bg.com has a wealth of information on. Its an amateur...

MOGVZ-Could you go farther on mobile base loaded antennas? Its my understanding that thebase load is to make up for lack of length and thereby match for frequency. Seems the size, style, mounting of antennas on different vehicles will affect output. Am i correct in assuming that mag mounts are...

Hey guys, have been watching and reading a lot of threads on here.....question on antenna setup. Referring to the thread on antenna analyzers, and x=0, swr......im wondering if itsgonna be necessary for me to invest in an analyzer. Im going to be installing a sirio 5000 as ive talked to some of...

Hey thanks 222bdfl, yeah, it was a used one, i emailed the seller and she said it was a telex and talked good. Funny tho, the plastic was stamped telex, but when i took the cover off the wire colors were right but not the same terminals as mine on the switch, looked like someone was in there by...
