The Corsair II has the RF performance to survive your plans, and has
fewer front panel controls to get messed up by the casual user.
I think you'll find this year that you will need 40m and 80m antennas in
preference to the 20m beams because its likely 20m will be dead all
night. Last FD it was dead from 2 or 3AM CDT to sunup. 15 wasn't open
all that much and 10m never opened in Iowa.
The big problem on 75 were all the home stations running kilowatts in
noisy situations so the 100 watt FD stations couldn't be copied in their
pile ups. Once the strong signals were ignored, the contact rate went
back up.
