I've always believed in pie-in-the-sky wishing.
Thus, I have always wondered why someone didn't put together a small 80-20m
or 160-10m transceiver with embedded computer w/sound card that would run
say MFSK16 and MT63 or some other robust/near error free/high throughput
(more than 150 WPM)
We have lots of comparisons of modes, but we don't but them side by side...how
about a comparison list like this...
mode -|- thruhput in WPM -|- %error free -|- robustness (%error free at what
SNR) -|- Bandwidth
You might have to qualify this by using certain power levels and receiver
John,
A little tongue-in-cheek there perhaps?
Needless to say, when you are communicating with someone else, the one
thing you want the most is to be able to receive their transmission
correctly. At least I would expect most folks do. To me it is the most
important characteristic, because if
I agree on three items Rick...as you, I want correctness...I want to know for
sure what the individual says. Second is speed. While I can't type very fast,
I can pre-type information and transmit it as a file or load a buffer so speed
is important. For me I would like at least 200 WPM for
The bandwidth issue to me is significant in that ... if all other things
are equal ... I prefer using the narrower BW mode.
If PSK31 was using 3 to 4 KHZ instead of 100 Hz, you would likely
feel much differently since the bands would be frequently clogged with
signals.
The only time I would

Ok...if I were using a keyboard-to-keyboard mode...and I was REALLY using the
keyboard, a 20-40 WPM mode would be fine if it were 99% error free and worked
down below a 0 dB SNR...and a 500 Hz or even 1 KHz bandwidth mode would be Ok.
However, if I wanted/needed to send a text ot binary file,
One of the great advantages of FSK RTTY is you can amplify it with
anything, linear or not and no harm is done. I believe there may be
other digital modes which may be capable of this but I haven't seen
anyone come right out and say so. Are there?

Hi Bill,
