[Elecraft] K3: KRX3 question

[Tom Whiteside]

Thanks Bill.    I like the 5 poles for the reasons you stated recommending them way back when.    I ordered the ones you spec'd based on the idea of covering the octaves...   I agree that the narrow ones are for more extreme situations but figured for $30 I'd get the narrow ones matched as well.     

To Jim's question - I mainly use diversity to switch listen to the transmit antenna in one ear and to a Beverage receive antenna in the other ear.    Sometimes this is an experience that defies description except you find yourself copying in very tough SNR conditions that you could not otherwise do.

Tom (and others planning to use diversity), this means you have the
following options using the current filter prices:

1.  Dual 5-pole filters (matched by Elecraft).  2 X $100 plus $30 = $230 per
BW.
2.  Dual 8-pole filters (no match needed).  2 X $125 = $250 per BW.

This tilts your decision toward 8-pole filters, however there is still an
issue of bandwidth.  Since the 400 8-pole is actually 435 Hz and the 250
8-pole is actually 370 Hz, I would definitely not order both.  

I'm faced with the same issue but will probably order one matched 500 since
my order was at the original price of $80 for a 5-pole...plus I like the
wider BW for contests.  I was never planning to use the 200 in diversity
mode (you can still use a 500 down to DSP = 250).  

BTW having used my 200 awhile in a few 160 contests, I would absolutely NOT
be without it for huge simplex pileups.  So another option for you might be
two 400s for diversity, and at least one 200 for the extreme situations we
sometimes have on 160.
