[Lowfer] JASON

Hi,

My intent is to leave the watering hole tonight and move up to 186450 to 
run JASON mode.

That is my intent.

As I'm reading the tech notes that come with the JASON software, though, 
I'm a little unsure of myself (even more unsure than I was BEFORE I did 
the reading).

Not that the notes are poorly written (Alberto) -- I'm just one of the 
most dumb people any of you will likely ever know...several orders of 
magnitude more stupid than the NEXT least intelligent person you know.

But I am going to try (nothing learned sitting on my hands) -- and I'm 
going to try a couple of different things:

The notes made perfect sense to me until I got to the table of values vs 
freq needed for interfacing a DDS board to a TX.  Not sure about this ... 
don't think it applies since I have the ZL1BPU exciter that the JASON 
software supports directly.  But I don't know.

SO I'm going to attach my windows computer (I DO have one ... I like to 
keep one around ... "know thy enemy") and run the software in serial 
output ZL1BPU mode.  I'll set the exciter's frequency to 186450 Hz.  I'll 
listen on my handheld SSB receiver and see what I hear.

Then, I'll attach that windows computer to an ASCII terminal and capture 
the output.  Then I'll program these commands into the exciter (leaving 
out the "A"s, as directed) and see if it sounds the same.  Then the 
exciter can run JASON without the computer.

IF IT DOES sound the same to me, then I'll hook my handheld receiver to 
the windows computer and see if I can receive anything.  My receiver being 
what it is (Grundig YB-400 -- sorry, it's all I have) I am unsure what the 
results will be.

As you can see, lots of room for failure.  But I am going to try hard as I 
can with the equipment I have (and the smarts I don't) to verify I'm 
sending good JASON before any of you waste any of your valuable rx time 
trying.

IF I am UNABLE to decode my own JASON, but I THINK I'm sending good JASON, 
I'll let you know, and go ahead and run it all night.  If you don't see 
anything there, though, please don't waste a lot of time trying.

Don't know what the conditions will be like tonight anyway for my 
vertical.  Temp now is 69F with rain coming.  It is supposed to turn 
colder tomorrow with clear conditions and lows of near 20F.  So if no joy 
tonight I may try again tomorrow night.

Wish me luck,
Eric

My goal in my beaconing operations is to provide many listening 
opportunities.
