Centrunk (CTRS) Project 25 VDOC System

[carcarjg]

Are you saying a callsign has to be given on the first transmission? Where is that listed in Part 97?

97.119 A "Each amateur station, except a space station or telecommand station, must transmit its assigned call sign on its transmitting channel at the end of each communication, and at least every 10 minutes during a communication, for the purpose of clearly making the source of the transmissions from the station known to those receiving the transmissions. No station may transmit unidentified communications or signals, or transmit as the station call sign, any call sign not authorized to the station."

The part that I see issues coming from is "No station may transmit unidentified communications or signals"

The P25 protocol is identified as much as D-Star and Fusion are. I don't recall hearing analog CWIDs accompanying those protocols, but I haven't really checked for them either.

All the D* and Fusion rpts near me have CWIDs or Voice IDs. The issue with P25 Trunked in a non-VOC setup is you cant TX voice or CWID without causing an OOR on any SUs

I'm trying to find the text from my research on the subject

Yep, GE and their descendants used it on EDACS, and various manufacturers use it on P25 (at least, it's available for P25).

Known as SCAT (Single channel autonomous trunking?)

If anyone has the SCAT firmware for the V1 site pros... I'm all ears XD

I don't know if this is the same group.

Address = Texas
Ord Name = Centrunk
Freqs = 451.8,451.8125,464.5,464.55
App Type = YK / FB8I(I want to know how this station code will work out)


I think its safe to assume it is.

[gatekeep]

but we've never heard of this system, this technology being deployed

It is very possible and likely they are using DVMProject (Digital Voice Modem Project), which is a MMDVM fork.

I don't think YK will work for a Itinerant License. It would have to be YG. Itinerant licenses can only be private, not commercial. The station class of FB8I looks legit according to my automated Form 601 software. But I don't think you can us YK or IK for itinerant channels.

So ArmadaIssue is on the black market now?

Care to enlighten me on this? As I understand it the distinction between PMRS and CMRS hinges on whether a radio service is a) offered to the public b) being resold for profit and c) interconnected to the PSTN

if you answer “no” to any of the 3 prongs it’s PMRS, if you answer “yes” it’s CMRS

I don't see any inconsistency with the technology being itinerant. The fact he filed as a commercial carrier may be a problem requiring more red tape.
That license application has been withdrawn without explanation. The individual has not filed again under his personal FRN. Maybe he refiled filed under a corporation.

I'm just going to say this, its a great community, Its all legal, I'm about to get on there system, and anyone can join, so why don't you sad hams stop talking about stuff you don't know about

I think I speak for everyone. But this thread needs to just die. I request a lock.
