Hello Chris, RR for all.
>from city apartment to a nearby rural radio site - every hams dream I think.... >zero latency Yes it would be nice. But for this, you would need a TCP/IP (or AX25) transmission through air, with a VHF or UHF link to control your HF rig. All with radio, the ideal... For information, the protocol followed for the TCP/IP control is in my WEB site (http://f6cte.free.fr) under "Specifications" - "Multidem_TCP_IP_Version_1.doc". 73 Patrick ----- Original Message ----- From: zl1boe2002 To: digitalradio@yahoogroups.com Sent: Saturday, December 08, 2007 8:16 PM Subject: [digitalradio] Re: Remote Access Desktop, and remote digital operation Hi Patrick, It is interesting that no completely integrated HF rig remote cntrol solution seems to exist as yet. Maybe the just-announceed LogMein Pro remote PC control software (with intergated audio) is one possibility. If one thinks about remote control from another point of view the only connections between the Ham PC and the radio is two-way audio (half duplex) and the serial path for CAT/CIV. The latter can be as slow as 1200 bp/s if need be. If these two could be multiplexed together then the path from PC to remote radio is one serial stream - potentially well under 9600 bp/s. And the link and could be as simple as dial-up modems, packet or via IP with something like the Lantronix XPORT - an Ethernet-serial converter so small it is built into an RJ45 socket. The Xport component can even provide simple web server access (skilled programmer needed)! A solution of this kind requires no PC at all at the radio end. And although we might laugh today at the idea of dial-up modems it provides zero latency and excellent security (probably the hackers today are too young to know or care about dial-up). Of course with modems we would not want to try and remote control from France to Canada but the typical application is from city apartment to a nearby rural radio site - every hams dream I think. It is said that soon every household gadget will have built in network access so why not the next generation of ham rigs? 73, Chris ZL1BOE --- In digitalradio@yahoogroups.com, "Patrick Lindecker" <[EMAIL PROTECTED]> wrote: > > Hello John, > > The remote control through TCP/IP exists in Multipsk.

Afterwards, F6CTE will be able to QSO with another Ham.
