Good Afternoon Gentlemen, I am looking to build a hi-fi quality audio repeater to feed audio for remote broadcasts of a non-commercial radio station which has been greatly annoying, as I need a specific IF filter for a motorola receiver a tu-540w and I have been unable to find the filter. In addition, the chief engineer for the station has been completely un- helpful. While I am not an amateur radio operator, I am building this repeater for amateur radio use on the 144-148 mc band and the engineer of the station claims he has an amateur radio license, but i am beginning to have my doubts and the engineer has not been supportive of building a hi-fi audio repeater. how can i confirm if the engineer has a amateur radio license? is there a listing of engineers and what licenses they have? i went through a lot of trouble to find the older tube type equipment to build this hi-fi quality audio repeater and want to make it work to serve the non-commercial fm station. what suppliers carry older motorola radio parts?

[Repeater-Builder] trying to build my first repeater
I attempting to build my first repeater. I have always preferred to have the best audio quality for my equipment. My training has always told me that tube equipment delivers the richest/fullest audio. So I have been rounding up all the tube equipment I can find. The equipment is all motorola and the model numbers are u43ggt-1000 and u43ggv-1000. how do I proceed on finding the paperwork on converting these to repeaters? thank you for your time. Yahoo!

[Repeater-Builder] Re: trying to build my first repeater
Perhaps I did not make myself clear. The repeater i am building will be nearly hi-fidelity audio and such is why i intend to use tube equipment. i worked in commercial 2 way radio in the 1960's and worked in broadcasting in the 1970's. tube equipment in highly reliable if properly maintained, which i can do. (i do admit that there are not to many of us left that know how to properly maintain electronic equipment. i am setting this up to volunteer a system for an group. --- In Repeater-Builder@yahoogroups.com, Bob M. [EMAIL PROTECTED] wrote: Your training and preference are great for hi-fi audio equipment, but repeaters are optimized for weak signals with voice only, and as such, fidelity is not one of their strong points. 50 - 3500 Hz is about the limit, and the user radios will make it sound even worse. Today's solid-state communications equipment far surpasses the older tube stuff as far as reliability, durability, and ease of getting replacement parts when needed. A lot of today's radios don't even need to be tuned - they're wide-band but still quite selective and more sensitive than the tube radios ever could hope to be. There's a ton of good repeater-building information over on www.repeater-builder.com and you would spend less time reading it than you would trying to make those old U43GG? radios perform the continuous duty cycle required of repeaters.

[Repeater-Builder] Re: trying to build my first repeater
the fact that they are mobiles and the design of the power supply make little difference an any piece of equipment can be re-engineered to perform a needed task. all that is needed is time and ability. simultaneous transmit and receive will be addressed by seperate antennas. 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. --- In Repeater-Builder@yahoogroups.com, Neil McKie [EMAIL PROTECTED] wrote: Well, it is like this ... us_communications1 wrote: I attempting to build my first repeater.

Based on items 1), 2), 3) 4) above, I would suggest you not attempt to make a repeater out of those radios. That should get you started. Neil - WA6KLA thank you for your time. Yahoo!
