I agree that's a great feature. I think Kenwood missed an opportunity with the D72 to do the same. How easy would it have been to allow coordinates to be stored with memory items and then show the 10 nearest based on the internal GPS. Just a matter of code :) 73, Sander W1SOP

I went to Dayton and the one thing on my shopping list was an ID-31A (I have 3 other D-STAR radios). I won an ID-31A as a door prize at the D-STAR Pizza dinner Thursday night!

Great little handheld. I like that it keeps a database of D-STAR repeater locations (I need to refresh from http://www.dstarinfo.com/downloads-for-icom-software.aspx) and using the built-in GPS, I can select repeaters "near me" ... cool. It was fun as I passed through airports along the route.
I have already plugged a USB GPS into the UDR56K (CPU board) and loaded gpsd (a daemon many programs use for GPS data) - it loaded and worked right away. Once the UDR56K is fully up, this will be the basis for sending GPS positions via D-STAR, APRS, AX.25, etc. :) The mass storage is a microSD, so keeping a database of infrastructure (frequency, location, etc.) is a natural.

Re: No 2m but still an APRS igate?

I don't think there is a 'universal' APRS channel for 70cm, like 144.39 is for 2m. Here in the Northwest, we use 440.800 for 9k6 APRS.

That is a great idea, nice........... Im liking it even more . He said: "Here's the good news though. If you have a current igate on 2m, you can replace the computer with a UDR56K, attach a USB-to-Serial cable to the TNC and radio to continue to service the 144.39 net, while offering 9600 baud or better APRS on the UDR56K's 70cm radio. Then you would have a dual band igate with less power requirement (by loosing the computer) and a much smaller package. Attach a diplexer and dual band antenna and you are ready to go."

Activity in Statesboro-Savannah Area?
"qrv@..." <qrv@...>
Is anyone from the Statesboro-Savannah (GA-USA) area
involved yet? Integrated APRS/D-Star systems sound like an excellent redundant-wireless communication network to backstop vulnerable wired, cellphone, and Internet networks. Integrating the currently isolated strings of networks on 2/220/440/9600 plus APRS and D-Star deepens the density of redundancy. Developing 440 makes sense, as does folding-in 9600 and 220, along with 2M. -- Thanks! & 73, KD4E.com David Colburn - Nevils, Georgia USA Android for Hams: groups.yahoo.com/group/hamdroid Restored to design-spec at Heaven's gate 1Cor15:22

Re: No 2m but still an APRS igate?
Sander Pool <sander_pool@...>
I will tune my igate to 445.925 and see what I pick up over the next few days. Near as I can tell all local (CT/NY area) users are on 144.390 but maybe I'm missing out on a lot of traffic. I will also run my mobiles on that frequency to see if any other igates are listening. I don't think igates announce their frequency but if non-144.390 is common in the US it should probably be included so you can see on aprs.fi and other servers. 73, Sander W1SOP

Re: Heard on the street

tizen.org is a fascinating project, joined by some
big players like Samsung, to foster development of Linux across a wide spectrum of applications and devices. A project like that reinforces the growing presence of Linux as a major player in the world of technology at every level. Apple, Linux, and Microsoft all use a "windows" type of gui - there is nothing whatsoever unique about the MS implementation. One neat new development is the kinect-type in-the-air interface where hand-gestures replace a physical mouse. Voice interfaces have finally crossed a threshold of accuracy where they also alter the way that we control devices. Accessibility for handicapped users and mobile ops are obvious apps.

Re: No 2m but still an APRS igate?
"John D. Hays" <john@...>
Hi Sander,
toggle quoted messageShow quoted text
Maybe I can clarify this a little bit. If you look at the wiki information in the link you included, 144.39 nor 1200 baud is universally used for APRS or igates. You will find there are UHF networks and 9600 baud networks, including 9600 baud UHF networks.
Obviously, anyone using a UDR56K for an APRS tracker is only going to be able to report to 70cm igates. The UDR56K was designed to be both a user radio and an infrastructure (igate, D-STAR gateway, AMPRNET, RMS, etc.) radio. If you are using it in infrastructure, say as an igate, it can do that. A frequency, modulation (FSK, GMSK, 4FSK) and baud rate (4800-56000) would be selected and the proper application loaded and run. Any trackers would need to match the same combination.
A lot of thought went into the selection of the band and the modes under which the radio would operate. The concept of "Universal" Digital Radio means it can be used for more than one application. So while one user might want to use it for 9600 baud APRS, another might want to run it at 56Kbps for file transfers in an RMS function, or to pass AMPRNET or D-STAR DATA traffic. Yet another user might want to run D-STAR Voice or Codec-2.
2 meters, suffers from being "too popular" -- in many countries it is only 2 mHz wide, with FM repeaters, weak signal, APRS, satellites, etc. all trying to squeeze into the band. A 56Kbps signal is not permitted in the US FCC regulations on 2 meters and would not be friendly to other spectrum users if it were.
The 219 and 222 band is interesting and may lend itself to a UDR type radio (the band is only available in a limited area such as US/Canada), so the thought is that it is better to use 70cm as a good place to start:
Here's the good news though. If you have a current igate on 2m, you can replace the computer with a UDR56K, attach a USB-to-Serial cable to the TNC and radio to continue to service the 144.39 net, while offering 9600 baud or better APRS on the UDR56K's 70cm radio.

The 440 aprs packet frequency used is 445.925. In some areas, its dead quiet, in some its packed. But there are 440 freqs to use aprs. It just means you have better propagation, no collisions and as long as your igated, it goes to the WEB apr IS. Respectfully Perry Chamberlain

Not just as a development environment; The stability of Linux makes it ideal for consumer grade products as well, which is why so many consumer grade products (like phones and TVs and routers and firewalls and... etc) use it.

Re: No 2m but still an APRS igate?
Sander Pool <sander_pool@...>
Right, if you have a local userbase that runs APRS on 70cm then this would be a great radio. It could even be an advantage that no one 'in the know' will be pinging your igate with 144.390 packets. But as a general purpose APRS igate it would not be very useful. http://info.aprs.net/index.php?title=Frequencies To be clear, I have nothing against UHF or any other frequency, of course. Clearly there are advantages to running 9600 baud packet over UHF. I was questioning the use of APRS in the flyer. I suppose anyone with the knowledge to set up a linux based APRS igate would not be confused and quickly see that it is not usable on the most often used frequencies. 73, Sander W1SOP

Re: No 2m but still an APRS igate?
Bill Vodall <wa7nwp@...>
the radio looks interesting but without a 2m radio how could itThe main reason I'd buy one of these radios today is to use as a home digipeater and iGate for our 96UHF alternate APRS network. UHF and 9600 is plug and play with the Kenwood mobiles but doing 9k6 is a pain with any other setup. All you need to make an APRS alt channel is one (preferably two) IGate on any other frequency. The hard part is getting folks to actually make use of it. (9k6 is a disadvantage here too but that's another discussion...) 73 Bill - WA7NWP

Re: No 2m but still an APRS igate?
"kc5zrq" <kc5zrq@...>
Really? VHF? I operate APRS and RMS Packet using UHF at 9600 baud. It works so much better than 1200 baud packet on VHF. The noise floor on UHF is usually lower. A typical ham dual-band antenna has higher gain on UHF than VHF. The bandwidth of 9600 baud AX.25 is more narrow than 1200 baud. There is lots more unused spectrum on UHF than VHF. I want UHF!
