Since pagers are available for peanuts as the cell phone industry steamrolls over them, it is frustrating to me that we hams have not jumped on these truck loads of text-messaging devices that can be converted over to a frequency in our bands and used for this kind of amateur radio text messaging capability.

Yes, and the Kantronics 9612 TNC's for the last many years can generate the POCSAG Pager formats, so it is easy to do.  I'm sure it could also just be done in soundcard software too if we just found someone motivated to do it.

Yes group codes can be very versatile.

Using paging devices on Amateur Radio is perfectly legal like any other radio.  It all boils down to use.  If you use it for setting up a one-way systemm for a pizza delivery service, it is clearly illegal.  If you use it as part of your overall local communications network of amateur radio volunters it is just one more tool in the tool box.

You just have to ignore the curmudgeons who have nothing better to do than nit-picking ways to prevent other hams from developing useful applications of technology.  A pager is simply the text-to-user device integrated into the normal local 2-way amateur radio communications system.

My Universal Text Messaging Web page
(www.aprs.org/aprs-messaging.html) has a link to a web page that highlights the conversion of these pagers to amateur use.  UNFORTUNATELY, the pager site activity appears to have dried up since nothing new has been posted in a year or so.  Just too many people buying blackberry's I guess.
But I'd sure like to see a revival.  These devices are out there by the millions.

An amateur satellite would make a great downlink to these pagers.  Again, the goal should simply be, any message, any time, anywhere using any device to any user by callsign alone.

We have been trying to get an article into QST on this subject since last November, and it will finally appear in the Septermber EMCOM issue of QST.  (initiall they rejected it because it was not "broad enough to appeal to a majority of readers" or something like that.

>>Amateur Radio needs to recognize its trememdous legacy of over a century of wireless text messaging and our ability to bring that connectivity to the field any time anywhere.  We simply need to link them together to meet our overall "Universal Amateur Radio Text Messaging Initiative", that is, any ham, any where, any time, able to text message any other ham anywhere using any hardware device, commercial or amateur by callsign alone.
>>Please see www.aprs.org/aprs-messaging.html
>>I count over 2 dozen existing amateur radio text messaging systems few of which are currently crossconnected.  Most talk only within their own constituents.  APRS and some others are already cross connected at the email level which then connects to cellphones and other wireless devices.  So crossconnecting at the APRS internetwork or at the email level is easy to do.  We just need all authors to consider transparent cross connection as a goal as per the above web page.
>>This has already been done for all APRS satellites and even the ARISS system when it came over the the Satellite APRS channel 145.825.  When ARISS is in packet mode, it enables text messaging and Email to and from the front panel of any APRS radio in the world via our existing network of APRS ground stations. See the downlinks on www.ariss.net
>>We have tried to get other packet satellites on that channel, SUNSAT, PCSAT1, PCSAT2, ANDE, RAFT and ISS all of which supported this universal text messaging.  We need more, and longer lived satelites.  And most any AX.25 cubesat could do it as a secondary mission.  We need to look for opportunities there.
>>We had GO32 also for a year or so until its recent demise, though it's frequency was different.
