[MRCG] Clatternet Times Freqs and problems

[boatanchor at martasystems.com]

Mark -

I think moving at least an hour earlier would be better given the conditions 
at this time of year.

Scott (his callsign is now WB6AS) and I ran some pre-net tests and finally 
we were able to copy each other. When the net started, it seemed things were 
not as we expected... freqs were off. Seems we need to do more testing - 
using our calculated L.O. freq (1/4 carrier) doesn't put us in the same 
place as NF6X.  Note that both of us are using modern synthesizers for L.O., 
not the T-195 PTO.

Interestingly, tuning NF6X into the Dovetron, then adjusting my transmitter 
L.O. synthesizer to match on loopback puts my L.O. at 1772.396, which 
doesn't fall on either the Mark or Space carrier frequency, but it's closer 
to the Space. Tried this multiple times to verify. I was originally thinking 
that the T-195 resting freq would be Mark, but then convinced myself that 
maybe it's supposed to be Space since we're running Mark-Low and I modified 
the switchbox to use the other side of the loop keying relay contacts (the 
T-195 doesn't have provision for selecting polarity). The mystery is why the 
L.O. isn't on either one of them.

Gotta love this - lots of knobs and complications.

Clatternet was challenging this weekend! The RTTY gods were grumpy this 
time. Folks who at least partially checked in included:

NF6X (yours truly, acting as net control)
W6JVE (from Arkansas! Good copy)
K6FWT (Tx only, and 120 Hz high)
N6CC (solid copy until the path died out)
WB6AZP (solid copy in pre-net tune-up; band died by net time; 120 Hz low + 
drifty)

I gather than Scott KG6EMD tried, too, but I didn't copy him. There were 
some wide-shift signals just barely audible above the noise floor, so maybe 
one of them was Scott?

Anyway, what do you folks think about the current net start time of 19:30 on 
40m band? Do you think we should move the time and/or band? I think I should 
be able to hit anything 80m or higher with my current setup. I can't Tx on 
160m yet, because my antenna is a bit too short to tune up there.
