The old GE mastr ll repeaters were nothing but the same circuits for the most part but the amplifier was available in 2 types.? Intermittent and 100 % duty so to speak.? The only difference was the

...and that makes it a "factory" repeater? No different then adding a fan to a commercial mobile radio, which BTW is what I've been doing for the past 30+ years ;) Bob NO6B

Eric, I've gone both routes with my 900 repeaters - first, I built one out of 2 mobiles tied to a controller and, then I built one from a purpose-built - a Motorola MSF5000.? (FWIW, I sold the

What part of Low Band are you looking for? -- Glenn (Butch) Kanvick KE7FEL/R 1-406-655-1232

I have a little bit of logic troubleshooting to do on one of these amps. I have a operating manual, which has two pages of the desired schematic. However, page 7-17 is a schematic, page 2 of 2. The

If there are no Quantar equipment limitations for operating a Range 2 Quantar on 146.730/146.130 MHz then I'm open for that. But, I was generally referring to the Range 1 Quantars with 125w PA. I

Hello Karl ! Explanation -- It’s balanced – not balance. For example, my trusty old Simpson 260 is an almost balanced meter movement. Even with it, when holding it in different planes (lying down,

Model / modules? Location? Those are important facts. If I saw this at a swapfest, I'd load it off your trailer and into my truck for free ..... 73 Jim N6OTQ

Eric, I've been building, modifying and servicing repeaters since 1977. I started out with the tube equipment running separate sites then a single site with separate antennas but migrated to the?

Showing my ignorance I did not know a "balance" meter existed. -- Regards, Karl Shoemaker To contact me, please visit SRG's web site at http://www.srgclub.org for the current email address. -

Does anyone need anything from this before it goes away? Cleaning out. Will Contact radio5000 (at) aol (dot) com

Very true on the TX phase noise point. I’ve fought with a user at 451MHz using an icom mobile with no bandpass or isolator. They were a few MHz away and desensing us bad. It turns out my desense was

Andrew, You may want to specify which range you require. VHF Range 2 Quantars (150-174) are much more common than VHF Range 1 Quantars (136-150). While the Range 1 Quantar will do the whole 2M range

Also, mobiles are designed for freq agility, therefore a wider bandwidth. The older GE MII and MICOR and MSF5000 , were tuned for fixed freq operation as a repeater. Narrow band operation. Not 138 to

Do not forget the issue of phase npise on a TX or the RX local oscillators. GE MII and MOT are usually a lot cleaner. I have experienced RX desense where Yaesu radios transmitted , vs MOT mobiles

I ran into what I think is the same issue a couple years ago. I had picked up an XPR8300 that CPS absolutely could not see. I bought a replacement network interface thinking it was a hardware problem;

I see no problem with using two mobiles and I do it all the time and the performance is identical to the fancy repeaters. Sensitivity: I don’t see much difference in RX sensitivity between most

There have been a lot of comments on this subject, unless I missed something, no one has said anything about NOT using amateur mobile radios to make a repeater. This would include Fusion. Often times

35 dB notch depth is a bit low with loops set for 0.7 dB IL. That indicates the capacitor is shorting out. Piston trimmer caps are rather fragile beasts. There are several concentric plates in the

For ham repeaters usually the ones that put them together out of parts know how to work on them and will take time to fine tune the repeater.? The ones that just set the commercial box down are not
