[Lowfer] JASON VS. WOLF

[Les Rayburn]

Recent successful tests with the new Jason mode at the 600+ mile
range have come rather quickly in it's development. While it seems clear
that Jason in it's current form is no match for WOLF in terms of weak
signal work, it does point out the value of a coding scheme that will
allow for more rapid communication on the LF band(s).

I would submit that this early success is due to one major factor. Jason
is based on a GUI interface, while WOLF remains rooted in a semi-DOS
world. One is fairly easy for listeners to master, while the other requires 
a lot
more trail and error for success.

The "early-adopters" of WOLF mostly came from those within our ranks with
experience using Bill de Carle's BPSK programs., while Jason is being used by
a major broader range of listeners.

So what is needed to move forward? Here's a list that I think others can add
and subtract to:

1. We must recruit more folks with computer programming experience to our
ranks. It's fairly clear that this generation of "lowfers" will make the most
strides on the signal processing front, not the RF front.

2. Serious thought should be given towards moving Jason in the weak signal
direction or perhaps offering a "weak signal" mode that would take advantage
of it's GUI based interface...while using some of the repetitive signal 
processing
techniques used by WOLF.

3. Those developing the coding schemes should also look at a higher powered 
version
that would depend on the new generation of 24 bit soundcards and faster 
processors.
While this would eliminate many hams, who are often slow to upgrade their 
computers,
it will likely be required to push the weak signal envelope.

4. Those of us lacking the computer skills to help advance the state of the 
art need
to be willing to do our part too.Testing new modes is very important...Dex 
should
be commended for his early acceptance of this new mode.

We must also be willing to support these software developments financially if
necessary.

I'd love to hear the thoughts of others on this, especially from Alberto, 
Stewart,
and Bill de Carle who are the real trail blazers here.
