[Elecraft] experience with CW and settings

[Phil Anderson]

Hi Gerald, KC6CNN,

Like most folks, I live in a suburban area so my noise level is high for 
40 and 30 meters compared to those lucky folks living in rural areas.
Living just two blocks for a shopping center doesn't help! For me 
turning on the AFT filter is helpful in reducing background noise (both 
random and close in signals during contests); tuning is then a bit tight 
but using three digits showing for fractions of a kHz makes it 
manageable. I leave the RF gain fully on. To reduce noise levels in 
general (which helps with CW too) I added a second receiver (SUB RX in 
K3), attached it to a 20-meter Beverage antenna via the AUX antenna 
input option and turned on the DIVERSITY MODE RX feature. With these 
additions, the K3 does a better job with the CW decode as well, although 
I seldom look at that any more. If you like, I'll send you a writeup on 
my 20-meter beverage; I wound my own cores for the 450 to 50 ohm 
matching transformer. To my surprise - with just 70 feet of back fence 
room, I gained over 2 S units for S/N, as noted on my P3 with I hook up 
the beverage to that for testing.

73, Phil, W0XI, Lawrence, KS.
