[Elecraft] Contemplating Purchase of K3

[Rick WA6NHC]

You may note on the Sherwood list that the difference between the 400 
and 200 (5 pole) Hz filters is 3 db for close in spacing.

If you DX or contest, that could make a difference.  I have the 400 (8 
pole) in both receivers, but I'm now wondering about changing to the 200 
filters 5 pole or 250 8 pole (I'm adding the new synth, when the 
backorder is fulfilled).  An edge is an edge but I suspect the 3 db is a 
rather bare edge.

There is filter choice commentary on the Elecraft site, updated since I 
made my purchase.  Consider that required reading.

Can someone who has made the change comment?  I can't do a comparison, 
all filters slots are filled, both receivers matched.

If you want to use the K3 on local 6M repeaters, the 13 KHz filter 
should be added (good for AM too).  Adding the KXV3a gives you other 
useful options (required for either preamp).  If you operate digital (JT 
modes in particular), the TCXO option helps.  The KDVR3 saves your voice 
if you contest or DX.

If your computer does not have a serial port, the Elecraft cable (comes 
with, make your choice which flavor you want) is fine.  Along that line, 
getting a multiport USB dongle is simpler in the long run (I have a 4 
port, so one USB controls everything K line).

If you want to operate on the experimental band, the KBPF3 is required.

If you ever want to take the K3 someplace else (field day, portable, 
mobile in the RV) the tuner would be handy to have; else get the KAT500 
(later? also in preparation for an amp; life is too short for QRP and 
you can always turn the power output down).

Rick's rule of radio: Buy ALL the options you THINK you might EVER want 
at the original time of purchase because the budget will never be there 
to add on.  However Elecraft is the one exception, mods and updates are 
generally simple.

I'd strongly suggest looking though the options and consider how YOU 
operate, how you intend to grow and if they'd be useful now (buy) or 
later (budget).  The answer to your question becomes self-evident. Since 
you can add more later if your mode of operation changes, you can adapt 
(building a budget to get you there).

Caveat:  If you're new to HF, contesting or DXing, having the receiver 
dialed in for the WORST operating conditions is your best advantage... 
close in strong signals are common in CW (your best DXing mode) and digital.
