[RTTY] SO2R Problem

I didn't see any mention of bandpass filters.  A set of them are 
must-have items for so2r on a city lot, even at low power.  They 
are not cheap, but it's just part of the buy-in for so2r.  I 
recommend a pair of Dunestar 600's.

              Rig : FT-1000MP; Icom Pro II, SB-220, Alpha 8410

         Antennas : SteppIR 4 element, Mosley CL-33, HF6V, 40 Vee 
at 60' and 40 rotatable dipole at 80',
                          80 sloper at 65', and Crazy J 80 meter 
antenna at 48'.

          Soapbox : First time achieving a million points but it 
was costly.  Excessive RF took out the front end of the FT-1000MP 
after 2 hours.
                          Lost 10 meters on the PRO II on Sunday. 
As of Monday morning, no receive or transmit with  the PRO II on 
any band.
                           I have an Icom 706 until the big rigs 
get repaired or replaced.



I should have realized that something was wrong, when the 
wattmeter on the MP/220 combination showed a huge backward 
deflection, when I keyed the Pro II/8410 at 1200 watts.  The 80 
meter Crazy J was too close to the 40 Vee and vice versa.  I put 
up the new 80 meter antenna to see if it was better than the 
Butternut.  I had no RF issues in the ARRL RU without the new 
antenna.  It's tough on a small city lot to get any separation.

This was probably my last SO2R effort.

Dupes were the least of my problems!!!
