[digitalradio] UK DV Nets ??

[dave_m1ctk]

Are there any at all ? There seems to be little interest in the UK for 
DV. Someone please prove me wrong !

I have seen the excellent DVD from KN4AQ if this does'nt get any UK ham 
excited for DV then nothing will !

There must be some European DV nets on anyway - DL land ?

RE: [digitalradio] how to install TNC with SL/USB at same time?

[Cortland Richmond]

Chas,

I've used a TNC on a rig's accessory connector and soundcard on its
mike-plug before. Since they use different interfaces, they can be keyed
separately. 

I suspect you could use a resisitive audio mixer for audio I/O, and diode
steering to key the rig, putting all the rig interface on the acessory
connector.

[digitalradio] how to install TNC with SL/USB at same time?

[schuetzen]

Did not really find much on the subject.

am presently running a TS-480 with a SL/USB into a WinXP Pro laptop
for MARS.  I want to plug in my PK232 USB as part of this
semipermanent install which is really working very well.

I am using the setup for Army MARS data transfer during training and
actual incidents .. last being Edouard and Dolly.  It works great! 
But I want to plug my TNC which is a completely upgraded PK232 with
all the bells and whistles for low power, internal sound card, USB,
etc to give me the additional Pactor I capability.

Is there a way to share the PTT connection between the
laptop>Signalink>TS480  so that it becomes a matter of switching from
the MixW to the Pactor SW and back again? with no changes on cables,
physical switches, etc???

Hope this is more clear than I am afraid that I have made it.

thanks

plug into the mike socket on the signalink or the pc ?

RE: [digitalradio] AX.25 vs Something New

[Rud Merriam]

Chuck,
 
No problem. It may just as easily been something I missed. 
 
On the SEDSAT Wiki page they describe the "sliding window" technique used to
stream packets. As I recall this was used in the Kermit protocol for PC to
PC file transfers. Something similar, modified for half-duplex channels,
would be an improvement to our RF digital communications. I liked the point
about not needing a timer to monitor timeouts with the sliding window. AX.25
has a plethora of timers that make it a hassle to implement.

Rud,
I said 

It was in the Design
 Notes
par. 2.2.1.

However, I now see that I got off the track and that page applies to Design
Notes for the 
SEDSAT-2.  Maybe the par. on fx.25 and the list of possible tnc's are not
connected together.

If that is the case, then Sorry for the confusion.

Chuck
