Actually, when an end-user station becomes active on the air, its internal "node" should broadcast only an empty routing table (or, maybe, a saved table from the "last known state" of its internal node). As soon as the "node" receives the routing table from the other station(s), it becomes populated with new routes and, accordingly to the new routes, redirects his end-user's data and (dis)connection requests (SABM's, DM's etc) to the best possible route etc ... > Flexnet was probably the best AX.25 system designed with working auto > router, but still it took some time before the routing tables were > updated after a station connected / disconnected.

The hidden transmitter problem might be an issue too, but at this stage of invention I did not think about, considering that an internal node incorporated within an AX.25 station would just add some more traffic (broadcast routing tables) - that might be usable in areas where are not 'official' nodes in use (rural areas or something like that, so every user can serve as a network node for the others).

[digitalradio] Real time audio frequency multiplication sofware
Has anyone seen such a software as a real time audio frequency multiplier .. Ie pc soundcard based , audio in / audio out .. not frequency shifted but multiplied in frequency by a factor ..ie x 4 :- 200 hz in = 800 Hz out 400 hz in = 1600 Hz out 800 hz in = 3200 Hz out The event time is not changed, so its not like a tape speed changer where the duration is also modified .. amplitude liniartity would be 'nice' but not 100 % important can it be done ? has it ? music production ? Tnx- G ..

Re: [digitalradio] MFTTY error '380'
i don´t know where the error message is coming from i never deinstalled the soft just overwritten the previus version with the new one but you have to "unclick" make shortcuts to programm folder and "uncklick" make shortcut to desktop i worked fine for me but the cleanest way is everytime you install a new soft you should deinstall the older one first hope that helps a bit greetz dg9bfc - Original Message - From: kh6ty To: digitalradio@yahoogroups.com Sent: Friday, January 16, 2009 3:00 PM Subject: Re: [digitalradio] MFTTY error '380' The reason for a version change IS because something has changed.

Re: [digitalradio] MFTTY error '380'
Yes I have been deleteing the program before I install the new one. Maybe Norbert can put some light on this, I need to get the Com-port1 to work, I have to use VOX, in the program it access the com port-1, because if I try to start MMTTY it sayes it cant star com port 1. MFTTY is just not keying the radio. The radio works with MMTTY, HRD, and Commander with MultiPSK on keying the radio all works fine.

Re: [digitalradio] MFTTY Path Simulaitons
dear tony what speed did you use for the path simulation? when you take a slower mode the s7n will be higher cause the filter are narrower that´s why i asked about used speed for the test greetz dg9bfc sigi - Original Message - From: Tony To: digitalradio@yahoogroups.com Sent: Friday, January 16, 2009 1:49 AM Subject: [digitalradio] MFTTY Path Simulaitons All, It's good to see the enthusiasm about MFTTY. It has a nifty GUI and its easy to use. A few have mentioned a lack of lack of sensitivity and that does seem to be the case. But I think it's safe to say that we don't always need to bring an elephant gun to a turkey shoot ; ). For what it's worth, and with all due respect to the author, I've tested MFTTY with an HF path simulator and it is less sensitive and less robust than say PSK31. On air tests seem to show that the mode performs well with low power under quiet conditions. Many thanks to Norbert and those like him who give us the opportunity to experiment and play with new modes. If it wasn't for them, we'd still be lugging those heavy RTTY machines into the shack ; ).

if you want a multimode programm then go for multipsk it has many many modes built in and it is easy to use it is the best multimode software that i could find but surely others will tell you that there are several other soft available try it out it is a freeware soft greetz dg9bfc sigi - Original Message - From: clarkmvimi To: digitalradio@yahoogroups.com Sent: Friday, January 16, 2009 2:28 AM Subject: [digitalradio] New to the Group Good day.
