[Elecraft] [K3] CW Skimmer and LP-PAN Bandwidth Limitation

Just a word of caution for anyone planning to use CW Skimmer with the
K3/LP-PAN. If using the Softrock-IF mode, which is intended for
radios like the K3 with a fixed IF output, Skimmer has a bandwidth
limitation of 24 kHz (i.e. +/- 12 kHz around whatever frequency the K3
VFO is set to)...and the spectrum display will only be 20 kHz(i.e. +/-
10 kHz). The way you would see calls on the full 24 kHz will be to
look at the decoded callsign list...not the spectrum display.

This is an internal limitation of Skimmer and not due to either the K3
or LP-PAN, both of which can provide 192 kHz. After many emails with
Alex VE3NEA, I don't believe this limitation will be changed in the
near future, but I hope I'm proven wrong.

If you want the full 96 or 192 kHz waterfall, use PowerSDR or WinRad.

73, Bill
