RE: [digitalradio] About digital reception and SDR.

[Simon HB9DRV]

Hi,

 

If Windows 7 crashes with BSOD then it's a driver issue - I suggest serial
port or USB soundcard.

 

If it's the program crashing shout at me - I've been *very* busy getting SDR
software written  but in maybe two weeks will be able to get back into the
HRD suite. I'll get a dump file from you...

Hal,

Seems the majority of MT63 activity is on 20 meters - 14108.0 / 14109.0. 
It is sparse though. I do see some using the 500Hz mode around 3586.0. I 
can meet you on 14108.0 if you like -- it's 0210z.

If you're operating SSTV via FM, any 2m amp will do the job. If you're 
operating via USB (like on HF), any LINEAR amp will do.

Re: [digitalradio] What mean "Too Wide"?

[Jaak Hohensee]

24.05.2010 22:45, Rick Westerfield kirjutas:


This would be a general definition that perhaps not everyone could 
fully agree on:


   Too Wide:  takes up too much spectrum bandwidth for the amount of 
information delivered or the speed of the information's delivery.


Rick, academically you are right. But the question/poll is about 
"keyboard" modes mental limit.
For me the limit somewhere around rtty45 bw. Olivia 500 too wide, mfsk16 
somewhere on the limit.


The psk31 is de facto standard. I think good idea to measure/evaluate 
things with this standard.


MFSK modes are undervalued but not in every case. For good or moderate 
propagation  psk31 is the best (not academically). But for 
poor/disturbed propagation and in higher latitudes there are better modes.
We can use many mfsk modes with different bw and tones. From standard 
user viewpoint -  more is less. RSID, Video ID are good things. But we 
need de-facto mfsk-standard like psk31 to fire psk-folk in case of 
poor/disturbed propagation to switch mode. This is 
strategical/promotional BIG step.
IMO Contestia 250/4 (or /8?) is enough good bw/speed compromise to take 
de facto mfsk-standard role. There are better modes/formats from speed 
viewpoint DominoEX11, MFSK16 or from snr viewpoint 250/16:

So what mean "too wide mode" mentally?
http://contestia.blogspot.com/

Poor or disturbed propagation constrains all of us into fewer bands 
for digital operations. With fewer sunspots, we all crowd the same 
bands which makes the "too wide" problem worse.  Some modes are very 
narrow and are spectrum efficient but have little error correction.  
Others are "too wide" but have lots or error correction and are 
fast.   As you very well know, these are the tradeoffs we all face.


   This definition might cause a bit of a "Food Fight" here on this 
reflector but hopefully . . . not.

Hi

Sometimes we hear, that mode or format is "too wide". What this mean?
Context - poor or disturbed propagation.
Please answer. Your answer help to see how different people understand
the term "too wide".
