Awesome, Hi Fidelity into my tinty sounding Kenwood, cheap external speaker, and better yet, that tiny little speaker in that tiny little HT. Why produce something that only so few radios will even notice the difference, if in fact you are able to make it. I heard and RC85 controller sound just as quality as the FM radio station here in out town. Save on the electric and build a solid staterepeater and have fun.

You are working under several misnomers. 1) Old, tube-type radios such as the GGV and GGT series are NOT expensive. In many cases, if you had a some laying around, you'd be lucky to find someone to take them without charging you to do so. 2) While audio purists do tend to prefer tube for hi fidelity uses, that truism in non-sequitur to RF applications, particularly NBFM applications. 3) As the saying goes, you can't change the laws of physics. My suggestion, as someone who has built repeaters from Motorola strips (Sensicon A's anyone?) is it simply isn't worth it these days. Modern radios are FAR FAR superior in just about everyway to those older G strips. Ken Yahoo!

What frequency pair are you planning to put this on? By the model numbers you gave, I seriously doubt the FCC will allow those radios on any commercial 2-way radio frequency.

Re: [Repeater-Builder] Re: trying to build my first repeater
He will probably need a copy of The Red Book or The Yellow Book to get it going. People who were into converting old tube-type Motorola gear back in the 60's - 70's to the ham bands will know what those two books were. However, the G series receiver wasn't a good Repeater receiver even when it was new, and was never intended by Motorola to be used in Repeater service. It was much smaller than the A series receiver, and was intended for Base Station and Mobile only use - not as a Repeater receiver. The Sensicon A receiver is the one he wants if he really wants to have an old Motorola Tube-type repeater. We converted lots of those to 2-Meters in past lives. I think I heard that Motorola still made a few of them as late as about 1964.

A tube repeater gear means you're obviously not paying the utility bill. An old GE EP-38 has got to run about $40 a month... figure a GE Progress Line or Motorola Research Line has got to be min $50 a month.

Re: [Repeater-Builder] Re: trying to build my first repeater
Hi Larry, I have both the Red Book and the Yellow Book here in case he needs either one ... but I most likely have the original manual on the radios he has too. Neil [EMAIL PROTECTED] wrote: He will probably need a copy of The Red Book or The Yellow Book to get it going. People who were into converting old tube-type Motorola gear back in the 60's - 70's to the ham bands will know what those two books were. However, the G series receiver wasn't a good Repeater receiver even when it was new, and was never intended by Motorola to be used in Repeater service. It was much smaller than the A series receiver, and was intended for Base Station and Mobile only use - not as a Repeater receiver. The Sensicon A receiver is the one he wants if he really wants to have an old Motorola Tube-type repeater. We converted lots of those to 2-Meters in past lives. I think I heard that Motorola still made a few of them as late as about 1964.

By the model numbers you gave, I seriously doubt the FCC will allow those radios on any commercial 2-way radio frequency. If going into the amateur radio band, you will need to adjust the transmitter deviation to conform with your local area band plan ... usually meaning +/- 4.5 kHz Deviation ... clearly not a hi-fi sound.

Here is a link to a pll (true FM) vhf Mastr II on Ebay. Throw that old junk away and use one of these and you'll have a great sounding reliable repeater. p http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemitem=5835754755rd=1sspagename=STRK%3AMESE%3AITrd=1 p If you are really into tubes I know a guy that has a few Ge mastr 330w tube amps that would go really well with the ge repeater. --- In Repeater-Builder@yahoogroups.com, us_communications1 [EMAIL PROTECTED] wrote: I attempting to build my first repeater.

I think we've been had.

WHAT I AM LOOKING FOR IS DIRECTION OF HOW OTHERS DID THIS. the radios are 30+ years old so i can't believe that i am the first to think of using the higer quality tube equipment. this equipment is very expensive and i was fortunate to have it donated to the non-profit group i am working with.
