[HCARC] 40 meter net

Bob-

  Thanks for conducting the morning and afternoon sessions of the HF Net.  I 
believe that you've found the sweet spot of propagation for a local net.

  The band was quiet, no QRM detected and little QSB.

  Here are the signals that were recorded from my QTH:

K5YB - 5/7
KC5RHF - 5/9+
WB2GEU - 5/9+
W1CPP - 5/8
AE0S - 5/9+
KK5IA - 5/7
K5KS - 10/9+
K5GIT - 20/9+

  I support the continuation of a Sunday Morning HF net and will participate 
in an afternoon net should someone pick it up.

  Thanks for your leadership.

Gang,

I was able to copy everybody up, here in Harper except KK5IA.  For the
morning session I used a Ten Tec Omni D while for the afternoon session I
used a Drtake TR-5.  Both had about 70 W output and the antenna was the same
for both sessions, a Butternut HF-2V.

There was no QRM or QRN here either in the morning or the afternoon.

In the morning, a question cme up about whether or not it was NVIS.  I
didn't think so at the time but I did try a few VOACAP runs.  For September
with smoothed international sunspot numbers of 80, 70 and 60 the
morning(1500Z) critical frequencies (vertical incidence) were 8.3, 7.9 and
7.6 MHz respectively while for the afternoon (2000Z) they were 9.5, 9.2 and
8.9 MHz respectively.  These sunspot numbers correspond with 10.7 cm solar
fluxes of 128, 119 and 110 respectively.  My estimate is that 60 is probably
the right number to be using at the moment, so it looks like for both the
morning and afternoon sessions NVIS propagation could have been a player.
Of course those of us with vertical antennas, K5KS and K5YB, wouldn't have
gotten much benefit from NVIS!  I may have to put up a low dipole before the
next 40 m net!

73,

Kerry
