Don't forget the I.C.E #196 product. This has stopped my COR activity, and

My best Diversity setup is on 40m: a Cal-Av 2D-40A (full-size 2-el
horizontal phased array with excellent gain and F/B) at 110' and a full-size
4-square vertical array with 60 ground radials per element.
While effective for receive (highly directional and quiet), the 4-square
can't

Congrats Bill! Think you're too modest, experience counts too ;o)
I had my first golden log 130 QSOs, 66 multipliers all good. K3, no second
Rx for this contest, only one short beverage and only 100 watts. Good enough
for 8th in the US.
I'm sure you noticed the recent IARU 3830 soapbox

Space Diversity can work wonders on 6m and 4m
So if we heard those relays switching then we're dangerously close to
damage occurring? We found that we'd be listening and usually right
in the middle of a guy giving his call you'd hear a click and a short
bit of muting in the RX... Looks like swapping out for the AUX RF
input isn't going to

2009 ARRL DX CW results are just out and I set a new US record for
SOSB/160. Final result was 428 Qs by 79 mults and the closest
multi-multi was K1XM with 430 by 76 (at W1FJ using a 4-square on salt
water).
Thank you Elecraft for diversity...I'll never use any rig without it!

Hi Doug.
I'm not (yet) on topband but reckon that diversity is worth a few dbs (up to
maybe 5 dB?) on the other bands, particularly on 30m where my RX antenna (a
30m fullwave wire loop)
It's funny that you mention this today as I was going to post something
about it as well. I got to try diversity receiving yesterday and what a
world of difference in copying through QSB.
Like last year, I'm operating portable out in a tent gazebo in my front
yard again this summer. I threw up
