Re: [aprsisce] DPRS working with APRS? (was: APRS at 2013 National Scout Jamboree (in work!))
- OK Larry,
Can you explain why you would want to have both DPRS & APRS on the same IC-2820 then if you don't want DPRS talking to APRS and vice versa? and what would be the advantage of just one 'Terminal Operator' being able to see all the site activity?
Sorry if these are stupid questions but I have little knowledge of DSTAR and DPRS.
I have considered getting an IC-2820 but if you have to choose between APRS & DPRS and can't use both together then I don't see the point, APRS will win hands down (at least around here).

For me it would be a great opportunity to meet Bob since I am on the west coast. I have emailed with Bob a few times when I was looking for more information for a rather large even that I setup a separate network for because of our shear number of units in the event.
I've found this: https://sites.google.com/a/nienhiser.com/david/d/W9GF.TinyTrak4-IC2820010Aug2009.pdf?attredirects=0 which details the addition of a TT4 to an IC-2820.
From that & looking at the manual it would appear that DPRS and APRS will work OK side by side on the IC-2820, however I'm not sure the two systems can talk to each other with just the TT4 & IC-2820.
I'm sure something could be set up to work though perhaps through APRSISCE32/64.

Now I wish I could go there and help set things up. Ray is a great resource on the DSTAR equipment and has told me with proper configuration you can actually run the DPRS and APRS off of an IC-2820 at the same time.
Great news for Jamboree.
We are now in touch with the right people. I forgot, but 9 months ago, ICOM had contacted me to work with them to cover APRS at the site. After an email crash, I had sorta lost the thread. But we are back on track now.
It looks like Icom will have the actual site covered, but we in the surrounding APRS community want to confirm the surrounding digis within 50 miles or so are configured properly. I’ll let everyone know if we need anything else. Of course if you are going to Jamboree be sure to bring your radio!
Another thing we can consider is dusting off those APRStt concepts to see if we can allow scouts with conventional walkie-talkies to enter their location using DTMF key pad. With a properly gridded map, only 2 digits of LAT and 2 of long can place anyone anywhere on the map. See how we planned to use DTMF at the 2010 jamboree. http://aprs.org/aprs-jamboree-2010.html
The nearest digi to the new National (and International) Scout Jamboree area at the Summi, WV is 40 miles away… We need to get a digipeater in the camp to give HT coverage of the entire camp before summer.
Take a look: http://aprs.fi/KC8SDN-5 The summit is about 40 miles WSW.
ICOM is outfitting the entire Jamboree station including 3 Voice repeaters and DSTAR.
Don Robinson WA4YYM has provided a link to the Ham Radio Plan for Jamboree and the section on APRS is yet to be filled in.
… Including an Igate would NAIL it for worldwide APRS texting from an HT anywhere in camp.
