[Elecraft] [Elecraft_K3] Re: K3 Trade my 1.8k for your 2.1k filter

[N2TK, Tony]

Hi Bill,

The K3 that I take to KP2M has a 2.7, 2.1 and 1.5 filter. During a contest I
use the 2.7 and 2.1, but never the 1.5. In rare situations chasing DX I may
use the 1.5, but that  is mostly to see if it helps. 

 

Hey, anyone want to swap a 2.1 for my 1.5?

 

73,

N2TK, Tony

Swap has been arranged. A few asked why I wanted to switch so here's 
the simple answer. I operate SSB primarily in contests. In the CQWW 
SSB I found the 1.8k was a little too narrow when running stations at 
high rates (>150/hr). In contests stations often call slightly off 
frequency (+/- 100 Hz) and I found myself needing to widen the 
passband to ~2.0k for best copy (which kicked in the stock 2.7k). In 
fact I never used the 1.8k much in the entire contest.

When working stations on a single frequency (such as a DX pileup or a 
net) the 1.8k works fine when you have time to tune carefully. And 
yes I do know how to adjust HI CUT (and Fc) for best readability at 
narrow BWs. Hopefully the 2.1k will be a better solution for me in 
the ARRL SSB DX Contest in March.

73, Bill W4ZV
