[SEDXC] FT8

[Lin Holcomb]

Mike,
Thanks for this info, I was wondering why I was seeing people calling JAs,
but not seeing any stations on my waterfall.  I was thinking that my RX
antenna was not working as well as I predicted.  I will give this a shot
next time I am at the lake house.  The only place I can work 160 at the
moment.

I have an extra long beverage on ground (1700') there that is going to be
used for WSPR RX on 2200m and 640m, but it still works fairly well on
160m.  The plan was to install a beverage on ground to Asia for 160m and
80m, but the temperatures were to high this year and I am paranoid of
snakes in the heavily wooded area at our lake house in which the beverages
are being installed.

73,
Lin
