Looking for just a voice identifier for a P25 repeater. Any suggestions?

The design bug in the RTCM is easily and effectively remedied, as documented in the videos I mentioned above. Excellent results. BTW as I recall WB6NIL (the inventor of the original "voter board"

2.5 inchs, is that bare foot or with shoe's? and pointing south east, that's for north hemisphere, what about in the southern hemisphere? Our aussie friend could be led to point to the wrong

Thank you for all the input. I know a diplexer would be needed at the bottom side at a minimum in addition to the Bp/Br duplexers for each repeater. The topside is what I was wondering about. The

Dude, no! Set up a private node not affiliated with Allstarlink registry and deploy a few RTCMs and go look what joe KC2IRV did with disciplining the 9.6MHz clock of the RTCM's PIC to GPS, along with

Does injecting instead of CTCSS, using DCS or digital squelch. What about instead using P25 or a DMR variant? I agree with others, those Quantar's should stay in service. Decent machines. We run a

One of the old simulcast solutions would be to have a master CTCSS oscillator at the control point and send the tone to all the transmit sites.? If you used RF links and they had flat audio response,

Looking at the license and contacting them a few years back produced that answer to me. - - David E Thurman Australian Shepherd Rescue Midwest www.aussierescueil.com President (309) 863-5211 Ext

We use the RTCM/Voter boards in a simulcast environment here. I have a UHF repeater with two sites currently (three sites are voted). They work well and there is no discernible CTCSS tone buzz or

Multicast might be easier... we have a couple of four site multicast sites operating in our area... poor man’s way is w/ same repeater input, different squelch codes, and different transmitter

Gee, Monty, I sure hope that's an urban legend! 73, Gary Could be worse... I've heard certain manufactures require burning Nag Champa Incense in the room, an NPR broadcast station playing at medium

Could be worse... I've heard certain manufactures require burning Nag Champa Incense in the room, an NPR broadcast station playing at medium volume and you've got to hold your foot 2.5 inches off

Are you saying you can't use the rtcm because of legality? I don't believe that to be the case at all. Maybe it's different in Australia vs the US but I don't believe so. Ross kc7rjk

Another thing to think about is to do what a few fire departments around here have done... add another site, use the same input frequency at all sites with a voter, but have different outputs. Yes,

Where exactly is the one repeater, and where exactly are you having coverage issues (and are they in one or more places, and is it indoors or out that's having the trouble)? A Quantar is actually a

That's the only way you're going to get any meaningful answers or usable results. Lacking the tools and skills to do it the right way, a broadband diplexer is the easy way out. --- Jeff

Gary, When operating 420-450, the Rx Synthesizer produces the opposite injection as compared to 450-470. So, when you program a frequency below 450 MHz, you have to flip the injection back the

Thanks. Figured it out for 7180. I don’t have prog cable but they used a different GPIO pin then the standard for ptt after I tested by grounding all inputs pins. The 880 seems dead if there’s no

I would like to recommend the the T. For many reasons mainly the cost and ridiculousness of having a cross band coupler mounted up a tower. Troubleshooting down the road (up the tower) could be really

Since you are doing this for a FD it needs to be done correctly. Done poorly you will have distortion and paging tones will be distorted and fail, the audio poor and CTCSS may even suffer. You need to
