The 2009 ARRL/TAPR DCC (Digital Communications Conference) will again be in Chicago on September 25 - 27. More information at www.tapr.org/dcc Feel free to...
I see that there at least was an option for P25 in the Mastr III. We have an analog M3, and I am NOT an M3 expert, but pretty knowlegeable. So, in a nutshell,...
All later backplane's can support the module however you need specific revisions of exciter and rx and IF as well as the control modules. TAC can provide the...
Thanks to both of you for the replies. Doug, I figured it was likely that there might be differences in those modules. Now I will have to go look and get the...
I've attached 2 pics I just took in our shop. It's pretty obvious. You need a 'racing stripe' version to even THINK about doing P25. WalterH On Thu, Feb 19,...
I am not sure I would base my determination on a stripe. Look at the REV version on each card and contact Tyco directly. Their service manuals are quite good...
Hi folks, I have the following I'm offering up to anyone interested prior to listing on ebay: 1) Motorola Astro Saber II (either a 438-470 or 403-470 split)....
Hi I'm new to the group, and am in the process of learning about P25. I'm playing around with a unit, a Racal PRC6894. Does anyone have any docs, info,...
I have 60 of these radios at work here, but never received any info on them as far as paperwork but I have experience with their use programming and such if...
Hello all, I'm a recent new owner of a ASTRO Saber II and love it. I'll be taking trip to Toronto (in Ontario, Canada of course) in the summer and I am...
... There's a P25 repeater up towards Collingwood but if you're right down in Toronto, you'll have no luck with it. Hopefully somebody in Toronto eventually...
I actually will be mostly in Whitby...and I don't think 185 km/114 miles will make it that far on 5W. Would be nice if there was a slot vacant on the CN Tower...
I have purchased a Motorola Quantar VHF repeater. The power supply has a bad / intermittent fan in the power supply. The station comes up and the fan is...
Tom, These are a non-encrypted digital mode just like (unencrypted) P25, D-Star, etc... so yes, they would be legal. 73, Nick N7QOR ... From: "retiredbynow"...
Is the protocol published openly? ... From: retiredbynow <retiredbynow@...> Subject: [APCO25hamradio] NXDN repeaters To: APCO25hamradio@yahoogroups.com ...
They are all published ... the catch is that (just like d-star), you must pay a licensing fee to use the protocol (if you were to market your own radios ....),...
Hi, Paul. Steve (N8JVN) here. Is that sensor actually a thermistor? I haven't worked on Moto power supplies, but the CPU fans in most Dell desktop computers...
Hi group, just wondering if anyone out there has any experience linking a Quantar to the outside world? I am just thinking about this and don't have any idea...
To directly link it on analog is easy: You need the wireline card (either 4W or 8W) You can run it in 4w (4 wire) mode and run TX audio on one pair and RX...
Ok Kurt, wow, that is a lot of info, what would you say is easiest or recomend? I think I have a DIU board and a few 4 and 8 wireline boards, does the DIU...
If you have the 2x RJ45's on the front of the Quantar, that would be the V.24 daughter card that sits on the wireline card. The V.24 cables are straight...
I have heard a number of fellow hams indicate that the Fed push for P25 is a mistake and that it does not make sense for hams to move to P25. I would like to...
