[Elecraft] ARRL CW K3 mini split...

2010-02-26 Thread cx7tt
John and Rick et. al,

 Rick sez, When I finally had the epiphany that the run station was 
listening on the last worked stations freq even if off a few hundred Hz 
my rate went way up. 

Probably the run stations that were most affected by this were K3 
operators since if they had it cranked down to minimum they never heard 
me when I was on their freq.   Darn K3!

I operated as CW7T in ARRL CW contest and frequently did the 
'mini-split'VFO B became xmit and VFO A was my rit. It was easy to 
pick off the 'big guns' and guys with kw/beams. The rub is when the 
pileup gets down to the 100w/dipole/vertical of which the majority of 
contesters depend on these guys to have a good score. One problem is the 
packet spoteveryone that clicks on the spot goes to the same 
frequency and it becomes almost impossible to get the call signs when 
the pitch are nearly identical. I found that by varying my 'rit' from 
-130 to +200hz around my xmit freq, it was easy to pick off the call 
signs.amazing how many guys got it vs didnt...the clue is how long 
is it taking the run station to answer a call...is he snapping off one 
callers or getting partial calls/calling QRZ more than once? The key is 
'be different' in the pileup...As Rick and John say, open up the BW and 
see where the guy is that I just worked, then zero beat himAs for 
me, I ran the BW down to 200 or 250hz while doing my mini splitI 
worked many guys who were S3 abv and below the run freq while the zero 
beat guys to my xmit freq were S9 plus.
And yes, a number of the K3 guys got in my log using this technique (I 
recognize a number of the calls from this forum, HI)

Look for all u guys in CW WPX in May...
