- 80dB, 1dB to 10dB steps. Adjustable for each band, but pan and
waterfall share the adjustment. Note: On some bands,
signals are off scale at N8LP.
|Ease of Installation||Requires installation of NaP3 software and usually an additional sound card. This requires a certain level of computer savvy. It's trivial for some --- difficult for others. LP-PAN should only be considered by computer literate users.||Plug
and play, but requires PC for firmware updates and additional features
through P3 Utility program.

|IQ outputs for CW-Skimmer & SDR
provides a full dual channel receiver with state-of-the-art DSP
controls, filtering, EQ, etc. Band and Mode buttons for K3. Provides
audio outputs for both Main and Sub receiver. Provides exceptional high
fidelity audio output for ESSB, AM/SW broadcast, etc. Has built in telnet server and displays
cluster or CW Skimmer spots in pan display.
function keys which will allow future control of K3 functions.
May also provide future ability to display and edit K3 parameters, read
PSK and RTTY, etc. P3 center frequency is tunable over a wide range,
while LP-PAN is xtal controlled.
