[Elecraft] K3 Filter Choices

[Jack Brabham]

I have the 1.8 and find it to be a great all round SSB filter, although 
some contesters are opting for the Inrad 1.5 instead.    The 250 is a 
must for CW, RTTY, PSK, etc..    There are also 500 and 700 hz 8 pole 
filters around for more casual CW or the wider data modes.   Haven't 
heard anyone say anything positive about the 1.0 kc filter.   The 6kc is 
needed if you are interested in AM, ESSB, or SWL.   The 2.8 "presumably" 
produces a technically better TX signal than the stock 2.7 but so far I 
haven't been able to justify the expense.
