[CALV-AUXCOMM] Correction Meeting Minutes

[Shawn Donley]

Dave

It would be rare to see NVIS propagation on 20M.   If you do hear someone “nearby” on 20 it’s either ground wave or back scatter.

The site below gives a real time prediction of the maximum usable NVIS frequency based upon location and the current state of the ionosphere.  The maximum frequency for NVIS is typically the “critical frequency” mentioned in any book on ionospheric propagation like the ARRL Handbook.  As I write this email, the current max NVIS frequency for us is about 5.4 MHz.

Maybe a few folks at Ranch Club or somewhere south.  A few folks north either at a public venue or home QTH.    Remember that a 80M dipole at only 30-40 feet is NVIS, so home QTH's are viable too.

But rather than participating as a group from one location, spread across the county and try to make NVIS contacts between ourselves as well as the Ohio stations that sponsor this exercise. A HF rig (100w max) and a good 40M/80M NVIS antenna is needed. A low-to-the-ground full size 40M or 80M dipole will work. Alternatively, a more compact antenna design can be found at http://arrl-ohio.org/SEC/nvis/Modified%20AS-2259%20NVIS%20Antenna.pdf An antenna tuner is still needed with this design.
