Private Calls on DMRGateway (Stock or Modified)

Private Calls in DMRGateway
Lets start with a look at the accepted method of doing a private
call to a parrot
PCRewrite0=2,9990,2,9990,1
SrcRewrite0=2,9990,2,9,1
Now this requires a TG 9990 private call to be created in the
code plug with tg9 set in a receiver group associated with
tg9990
we can eliminate the TG9 when we use
SrcRewrite0=2,9990,2,9990,1
But what do we do when we want to use multiple private calls to
different users digital ids?
Most DMR radio's were designed to make and receive private
calls. The radio contains the users call sign and digital ID
WE found that the following works just fine, by directing the
the return private call directly to the radio. This has not been
an documented feature but it works just fine.
Assume the radio has my call and Digital ID VE3RD 3023954
The following works in DMRGateway-4 basic mode after the use of
tg9004 to lock in Network 4
PCRewrite0=2,9990,2,9990,1
SrcRewrite0=2,9990,2,VE3RD,1
Alternately SrcRewrite0=2,9990,2,3023954,1 works as well.
Now we need to expand this to work on different networks using
the 7 digit tg method. This works in both the stock Pi-Star
DMRGateway and my DMRGateway-4
Network 1
PCRewrite0=2,1009990,2,9990,1
SrcRewrite0=2,9990,2,VE3RD,1
Network 4
PCRewrite0=2,4009990,2,9990,1
SrcRewrite0=2,9990,2,VE3RD,1
I run my DMRGateway with an 8 digit control method as follows
NOTE: This not a stock pi-star gateway as the stock gateway will
not handle 7 digit talk groups (either PC or GC) required for
use on TGIF
TGRewrite0=2,14000001,2,1,999999 // This line handles all group
call talk groups up to 6 digits and locks in Network 4
TGRewrite1=2,1,2,1,9999999 // After use of the above rule to
lock in Network 4,This line handles the new 7 digit talk groups
used on TGIF
PCRewrite0=2,14000001,2,1,9999999 // This line handles all
private call talk groups up to 6 digit and locks in Network 4
PCRewrite1=2,10000001,2,1,9999999 // After use of the above rule
to lock in Network 4, this handles 7 digit private calls
SrcRewrite0=2,1,2,VE3RD,9999999 // This line handles 7 digit
private calls.
From the TGIF Last heard, Accessing 7 digit talk group 3020733
Phil 3023954 (302395444) 31665 TGIF 12:13:11 S9+20dB -63 dBm //
A call to 14031665 Accesses Net4 and locks it in
Phil 3023954 (302395444) 3020733 12:13:35 S9+20dB -68 dBm // 7
digit talk groups now work on Net4 Only with the above lock.
The New TGIF parrot responds to both GC and PC on either 9990 or
31000. (Motorola Radios currently have a problem on TGIF with
private calls to the parrot - should be fixed shortly)
dialing up 14009990 as a group call triggers the TGIF parrot
dialing up 14009990 as a private call triggers the TGIF parrot
dialing up 14031000 as a group call triggers the TGIF parrot
dialing up 14031000 as a private call triggers the TGIF parrot
The return voice is heard on the radio as all returns on private
calls are directed directly to the radio, using the call sign
VE3RD which resides in the radio. (Use your own Call Sign here -
It MUST be the call sign programmed into your Radio)
I modified my Rewrite rules just for the test as follows and all
tests worked as expected, except that 7 digit talk groups can
not be handled in this method. This is the standard adopted by
the stock pi-star DMRGateway
TGRewrite0=2,4000001,2,1,999999 // This line handles all group
call talk groups up to 6 digits
PCRewrite0=2,4000001,2,1,999999 // This line handles all private
call talk groups up to 6 digit
SrcRewrite0=2,1,2,VE3RD,999999 // This line handles 7 digit
private calls.
dialing up 4009990 as a group call triggers the TGIF parrot
dialing up 4009990 as a private call triggers the TGIF parrot
dialing up 4031000 as a group call triggers the TGIF parrot
dialing up 4031000 as a private call triggers the TGIF parrot
The main point I am trying to make here is the use of your
callsign in the radio to handle private call return data.
Regardless of what tg or id you use, the return on your callsign
will handle all returns.
I can be found most days on 31665 or send me an email at
ve3rd@rac.ca

Hi Phil,
I was doing testing if you use basic mode it does not enter the
callsign it works in the two other modes
--- Code ---
SrcRewrite0=2,9990,2,CallSign,1
--- End Code ---
