Well... shoot, Rick.  Maybe next year, Stu, and Gary, and JB, and Bob, 
and the rest of the guys and I should skip over the pond to your villa 
in DE-land, and make a week of it.  We can line up some good German 
beer, cater in some good German chow, hang some wire, and enjoy the view 
from your bodacious backyard picnic shelter.  (Guys... I have seen 
pictures of it, and it is big... with a kitchen and all, so it would be 
a swell FD site.)    We will invite the Mayor, the local constabulary, 
and some local chicks to join the festivities.  It will be a fabulous PR 
event.  We can all take turns chatting up the US stations, who will feel 
compelled to tolerate us because we will be  DX to them.

I am SURE your wife won't mind if you put us all up for the WEEK ahead 
of time... so we have plenty of time to set up and get ready...  nah... 
no problem at all... I  keep a low profile except for my chronic 
snoring...  but that's no big deal...  at least not to me...and... 
and...      ;-)

Yeah...  ask her how that sounds?

	But seriously folks...

	This all brings up an important question that arose
	during a contest last Spring, namely, what CAN be
	done to minimize intermod between radios during a
	FD and when contesting - especially when having
	both CW and  SSB stations on the same band, with
	antennas less than a 1/4 mile apart?    The SSB guys
	were all located in pole barn type building, while
	the CW ops were working out of a medium sized motor
	home about 1/4 mile out in a big field.  Each
	crew had separate antennas separated by the same
	distance as the rigs were spaced.

	The CW ops were using Elecraft K3s (and one Kenwood
	TS-580)  while the phone ops were using two OMNI VIIs,
	and Orion II, an OMNI VI Plus, and another Kenwood
	TS-570.   We used TWO band pass filters on each of the
	SSB rigs, and I believe they were also using TWO
	band pass filters on each of the CW rigs.  Phone
	rigs were each running either an Alpha 76 or one of
	two Ten-Tec Titan linear amps.  I think the SSB rigs
	were all using 1 kW or more.

	The CW ops complained we were imposing on them, but
	I don't believe any of the SSB ops had problems
	from the CW side.

	I find it hard to believe the TT radios were all to
	blame...  we have done this before without so much
	headache, but I suppose the argument works both ways:
	namely, that either the Elecraft rigs are easily
	susceptible to problems, and that is their weakness;
	- OR - (perish the thought)  the TT rigs or the
	linear amps used with them were splattering widely
	over the rest of the band.
	

	Possible cures might include ?


	I WONDERED WHY WE DID NOT JUST LOWER POWER ON ALL
	THE SSB RIGS... but I was out voted on that, even
	though we were being told we were LOUD from stations
	contacted.

	***  ANY OTHER IDEAS ???  ***

	A list of things to consider would be greatly
	appreciated !   We can research the list from
	now until then and be ready to implement the
	various suggestions if the problem returns.


Thanks.

	PS - I am the newest member of the group ... so I
	would like to be helpful and contribute something
	to the group beyond a hot body at the operating
	position. . . . THANKS !
