[Elecraft] 2.7 vs 2.8

[Bill VanAlstyne W5WVO]

I think David has hit upon the crux of the matter with the tag line in his 
sig: "There is no pillow so soft as a clear conscience." Will you be able to 
tell the difference in actual single-receiver operation between the 2.7 kHz 
5-pole and the 2.8 kHz 8-pole filters? Almost certainly not. But will it 
make you feel more comfortable, knowing you have the better 8-pole filter in 
all slots? Undoubtedly, based on reading between your lines! Is it worth the 
cost differential? For you, sure, probably.

If and when I decide to buy the KRX3, I plan on replacing the 5-pole 2.7 kHz 
filter in my main K3 with the 8-pole 2.8 kHz, along with an 8-pole in the 
added KRX3. In the meantime, I'm finding the 5-pole filter works very 
adequately. (I already have the 8-pole 1.8 kHz filter installed for narrow 
SSB work, however, which works great in crowded bands.)
