Hello Harald, and also hello to all the semi-anonymous persons in the IRC!

The op25-dev yahoo group was set up long ago, prior to my involvement with the OP25 project.  As to the question about why it's marked "private" my own opinion is that "Y!" makes that the default (and that's due primarily to "Y!" business model considerations) and makes it non-obvious how to change the default.

I would be very open to moving the primary discussion group to an osmocom-hosted resource.  There is no reason to have it hosted at its current site and the are certainly no reason(s) that I know of to keep it "private".   I have always hesitated to ask you and Holger for anything because of my feeling that you guys already do a lot for us and even so on a 100% volunteer basis.  Nonetheless I would be in favor of moving the primary ML up to lists.osmocom.org going forward.  However I would also like to hear from others on this in case there are reason(s) I'm not aware of that this would be a bad idea.  It is a kind offer and I know we are not the only users currently hosted on "Y!" who are looking to jump to greener pastures.  On that issue the timing could not be better.

As far as the questions about the current architecture of OP25 there is more that I can cover in this brief note.  When the mainline gnu radio project deprecated support for wx-gui that was an almost-fatal blow to the project.  The GRC interface had never been a good fit for our needs and we had evolved a wx-gui implementation of a trunked P25 receiver (which blows the drawers off any current scanner on P25 simulcast trunking).  The removal of wx-gui caused a mental note to be made, not to depend too closely on gnu radio features, since they have a regular habit of disappearing.  Accordingly the direction has been toward running the receiver UI in a web browser, with plotting functions handled using gnuplot to generate PNG files for near real time display in the browser.  This interface (i.e., the HTTP interface) has matured nicely.

As for the other questions, I am in the USA and hate long trips.  If there is a conference in the New York area I'd be most interested.  OP25 also has xMBE voice synthesis and transmit support for d-star, yaesu fusion (both half rate and full rate), two-slot DMR BS as well as P25 FDMA.  I would be most happy to answer any and all questions about OP25 and would be grateful to have access to the forum(s) where these questions can be discussed more fully.
