[Elecraft] [KX3] KXFL3 dual-Passband Roofing Filter

[Rick Tavan N6XI]

The KXFL3 decision is pretty easy. If you plan to use the KX3 only with
simple antennas (random wires, loaded verticals, magnetic loops) and for
casual QSOs, you don't really need it. Unwanted signals will be weak enough
not to overload the DSP. If you plan to use the KX3, even sometimes, with
good antennas (big, high), especially in urban environments or
multi-transmitter sites like Field Day, or on crowded bands as in contests
or DX pileups, then you should have the filter to protect the DSP from very
strong, adjacent signals.

Another way of looking at it is, if the extra cost is not a hardship, get
the filter. Some day you'll be glad you did.

Either way, you're gonna love it!

73,
