Re: [digitalradio] Re: DEX vs. MT-63 -- Linux Version?

[kd5nwa]

Thanks, that site has all sorts of ham software a lot of it for 
Linux/Windows. Digital modes is something I have not tried before and 
I want to get involve so this will help a lot, I mostly run Linux myself.

I use Puppy Linux on a old laptop for it's speed and also to rescue 
data from PC's that will not boot.

I downloaded the live flPuppy Live-CD today with fldigi 3.0 built-in  
and have been playing around a bit with it and I am impressed. With  
everyting in RAM it is sure fast. I saved everything and will see if  
all is restored when I boot the computer again.

I am in the midst of a major reorganization of my radio
room and may dedicate a Kenwood TS-180 to digital modes,
including DominoEX and also sstv, dsstv, PSK31, etc ...
seems there are new digital modes or updates to existing
ones every week!

I need to find an affordable older laptop and run the
tiny Puppy Linux OS with digital modes on it. Possibly
an older IBM 600-series as they are very reliable and
lots of parts are available. Whatever I can be sure
will be natively compatible with Linux and will run
directly (if not charge the internal battery) on 12vdc.

WDYT?

Re: [digitalradio] Re: DEX vs. MT-63 -- Linux Version?

[Paul L Schmidt, K9PS]

The W1HKJ version of gMFSK supports the Domino modes, as well
as MT-63 (which fldigi omits - at least the version I've got),

Hi,

I *have* to use HP-UX at work so I avoid it and anything that reminds 
me of it at home; but think your only real choice would be Fldigi

See http://www.w1hkj.com/Fldigi.html

Others that use Unix/Linux might offer other options...

73,

Bill N9DSJ

What Linux app would you recommend that offers DominoEX,
especially DEX11 = -12 and DEX22 =  -9 with and without FEC?

I am in the midst of a major reorganization of my radio
room and may dedicate a Kenwood TS-180 to digital modes,
including DominoEX and also sstv, dsstv, PSK31, etc ...
seems there are new digital modes or updates to existing
ones every week!

I need to find an affordable older laptop and run the
tiny Puppy Linux OS with digital modes on it. Possibly
an older IBM 600-series as they are very reliable and
lots of parts are available.  Whatever I can be sure
will be natively compatible with Linux and will run
directly (if not charge the internal battery) on 12vdc.
