DVRS and it's use for talk-permit on a Quantar

So if you turn on DVRS and talk-permit, it seems to know whether or not you are hitting the repeater and gives the triple-bonk to transmit. My question is this:

Since this isn't actually a DVRS, is it just hearing the repeater output and assuming that means it is working?
If it doesn't hear the repeater, does it NOT transmit at all or what does it do?

I use this on a daily basis. It's pretty neat. When it doesn't hit it, it gives a failsoft tone, and reverts TX to simplex (or the current RX frequency for that personality). I find it useful, because it tells me if I'm hitting the Quantar or not. It seems like it checks real quick when you first key-up to make sure you're hitting it.

Also, it will "ping" the repeater every now and then. I don't know why.....probably just to see if it's still there or whatever.

Ok, so if that is on the ham bands and your radio is transmitting by itself.


Ah, yeah, ok.............

Yep, it sure does transmitt by itself, on the ham bands. About 5 10ms transmissions, to be exact.

Yeah, it's best with amateur radio we don't attempt to advance with technology.

Don't start that argument, but show me where you can have a radio transmitting at random unidentified on amateur frequencies?

Let me guess, soft ID is good enough of an ID for you? Ah, yeah, ok.............

Seeing as it's no worse than D-Star, AX.25 call/SSID or any other form of digital ID, why not?

Why not use advanced technology in amateur radio? If nobody advanced, we'd still be using morse code. No? The whole idea behind ham/amateur radio is to experiment and play with new/old stuff.

Rayjay's radio's soft ID is definently a form of ID. Anytime a radio pings the Quantar, the soft ID is logged, and the Quantar ID's. If this form of ID is OK'ed by the regional frequency cordinator (which it is), I'd have to agree too.

This is a cool feature for ham radio. If everyone's radio was set for DVRS talk permit tone, nobody would get keyed on.

Automated repeater kerchunking? Cool?

NOT!

Do that around here - once we figure out who you are - look for an OO card in your mailbox.

BTW, has anybody verified on a service monitor that those "pings" are actually long enough to contain the soft ID?

XMO, that's talking my "cool feature" comment OUT OF CONTEXT. If you read my previous post, your "ping" ID question has already been answered. Here is is again..... "Anytime a radio pings the Quantar, the soft ID is "logged". If the soft ID can be logged, then it's transmitting the soft ID. Your assumming the radio is pinging every 5 minutes - not the case. Program your XTS4000 with this option and monitor the duration between the pings. Not being concerned about the soft ID, you'd be able to just listen to the input on a scanner and see how often it pings.

How many times have you been stepped/keyed on? You get done talking, unkey, only to find out that someone else has stepped all over you. This happens all the time on public safety/ham/business frequencies. Programming your radio for DVRS eliminates the possability of this happening. When the radio's ping envoked the quantar's identification, make it ID with a differnet NAC, then you don't even have to listen to the repeater ID (if it annoys you that bad).

XMO, you ever come to Chicago, let us know. We'll give you a dig ID so you can try this out and you can see it working first hand. Offer is open to anyone else as well.

Cheers

Logged by what? Quantars don't decode or log anything.

Not that the ID matters anyway. I'll wager that the majority of OO's will tell you that even with an ID, only certain classes of amateur stations such as repeaters and beacons can transmit automatically - so you still get the card in the mail.

I give up Quantar infrastructure expert.

Carry on........

Wait, hold on, how is it possible to log IDs? I'd be interested in doing this for fun and/or possible future need. I would imagine it needs some RNC backend equipment.

"...how is it possible to log IDs?"
--------------------------------------

That is a good question - which is one reason I originally asked: "Logged by what?"

Digital service monitors can understand P25 ID's. Properly optioned mobiles & portables can display ID's so the possibility exists to somehow tap into that display data.

Infrastructure wise, the Centracom Gold Elite consoles can display ID's. To do this requires an ACIM [Astro Communications Interface Module] connected between the CEB and a DIU which is connected to the Quantar [or an ACIM can connect to an properly optioned XTL Astro Desktop] Somewhere in that configuration the data circuits could be analyzed and perhaps a logging / display device could be created that would emulate the ACIM and connect to the DIU to receive the Astro signalling.

With that capability, you could create a 'smart' repeater system that would use P25 ID's in a manner similar to the way the STROKE system used MDC ID's.

My friend who implemented and designed the MDC Scrutinization software that Stroke and Fishfar systems is actually thinking of possibly releasing a ham version. Not sure how much it will cost, but it's a pretty handy program.
