genft8 now looks at sign of n3 and i3. If either sign is negative, generate a type 1 (classic) message. Otherwise generate type 2. Type 1 seems to work. Type 2 does not yet work.

Several enhancements to DXpedition mode:
...
1. Insert dummy report when Hound is called by complex-callsign Fox.
2. Allow Fox to transmit anywhere between 300 and 900 Hz.
3. Restrict randomized Hound freq to the range 1000 - 3000 Hz.
4. Suppress Fox signals that would be duplicates.
