[Elecraft] LP PAN

[Leigh L. Klotz, Jr WA5ZNU]

Brett,
Thanks for pointing it out.  It was an old screen shot.  I updated it to 
a more recent one as the package does provide frequency control.

As for the bandwidth of the display, it's purely a function of the sound 
card.  On Linux, the EMU-0202 sound device supports 44.1 KHz unless it's 
sent a USB command to change sample rate.  I've worked with some other 
Linux folks around the world to help fix this, and the results should be 
coming out in new versions of the Linux "ALSA" sound system soon.  
Unfortunately, it doesn't seem to get past 96 KHz.  (The Mac driver for 
the EMU-020 has this same limitation.)

You can use quisk and the LP-PAN with a less expensive sound card such 
as the Griffin iMic or a 48KHz Creative USB product, all in the $40 
range, and get a 48KHz bandwidth view coverage.  If you're a CW or 
digital mode operator, that's pretty much all you need, and it's about 
half the cost of the EMU-0202.

I don't know what Elecraft's plans are, but I believe there's room for 
both standalone display devices and shack computer integrated devices.
Quisk is an option for those of us who have the LP-PAN and use Linux in 
the shack.
