For those integrating Motorola SpectraTac or DigiTac with non Motorola receivers or Motorola receivers lacking the C269 option. Those voters require 15 ms of silence after the status tone drops and

DCFluX Is this a new RTCM? Details please?? -- The Real RFI-EMI-GUY

Stephen, You could build your own in case you find an older one. That's what I do (farmer thinking process). If they don't make it, I will. A simple set of flop flops (IC) lead by a DTMF signal should

I would rather use a fan dipole, no balun.? I use a antenna analyzer and have a light tuner anyway. I am suspicious of all the QRP baluns for end fed.? Anyone is likely to bump the power which leads

If someone is looking at buying some of the RTCM, my want to look at doing some simulcast. Mick - W7CAT

Yes. Motorola UHF community repeaters were done this way for years configured the following way: * 500 MHz or more spacing between transmit frequencies * 4 cavity Bandpass duplexers on each repeater *

Bob,? Option 3 might work, only if all the repeaters (stations) are under the same “roof” by that meaning, the same Club/Org/Owner. If they are not, will all the Clubs work together?? In my

I don't like the voltage drop when using a Powergate. If you simply use a design from the commercial/public safety and microwave folks use... Float the power supply directly across the batteries. With

Allstar/RTCM deals with audio delays by applying a GPS derived timestamp to every frame of audio samples so the voter can align them. All the RTCMs in the system have GPS receivers with 1PPS outputs

At most of our sites we have multiple repeaters and other equipment running from a single (or typically dual) 13.8v supply. One site has over ten repeaters (all 25 watt or less) running this way. But

Got a link/datasheet @Matt Krick <dcflux@...>? Looks interesting...

Radio Thick Client Module just dropped. >

I once had two Quantars on UHF sharing one antenna...one on 451.5 xmit and the other on 444.5 xmit.. took a 6 can notch only duplexer and some careful tuning..the 449.5 side had about 7 db loss which

The problem that I see with a lot of these new voting systems is they don't interface well with external controllers. That is to say, you can't enable or disable receivers using logic lines on your

Mike, I'm interested, what's your email address or number? Thanks Mike / K5JR Nov 15 #195648 ( /g/repeater-builder/message/195648 ) Steven, I have a Doug Hall that I no longer need

I would think, the biggest issue with digital over internet would be getting your audio delays to line up. Although, I could be wrong. If its continuous voting S/N, it will cause issues. Someone

"Put all the eggs in one basket and carefully watch the basket." If the funding is there, I'd go with option 3, and also add some alarming/remote monitoring to the generator and DC power system. Eric

I would think the first step is to measure your typical power outage length. We have a site in Crossville, TN (very rural). They don't have a smart power grid, so when they have to do work, there have

You will spend much more for a combiner system to do what you want than replacing the bad antenna. It can be done but not cheaply. Sent by me

The most important item is never assume the generator will always start. The second thing is between the commercial power fail and generator start you will be without power even if just a few seconds.
