Comments:

Casual operation to do MMTTY profile experiments 
for the WPX RTTY in February.  I did as much SWLing as
operating.  For the first time ever I was hoping 
for weak signals and lots of QRM.  When I found a weak 
signal, I'd try to work them and then stick around and 
copy them for a while.  Everyone spread
out sensibly so there wasn't much QRM.

I compared my own home-rolled profile (IIR, BPF
Tap=256 and FW=80, Oversampling and Ignore Framing 
Errors) to the AA6YQ-FIR-512 profile by 
running two MMTTY instances side by side.

My profile was much easier to tune. Otherwise I could 
not tell any significant difference between the two.  
No doubt FIR-512 is better on a test bench, but 
it's hard to prove that out in the real world.  

I'll go on tweaking my profile but it's difficult to do 
tests with no sun spots and so little activity. I think 
the only other RTTY contest between now and the WPX is 
the XE RTTY, so I'll show the flag there.  Sometimes I
think that if it weren't for contests, I'd hardly be 
doing any operating at all.  

I hope to see everyone in the WPX RTTY.  Keep warm.

73,
Kermit, AB1J
