[HamWAN PSDR] Remote SDR receiver available

[Bart Kus]

Oh, it was hacked, I think via one of the hacked modems.  Modems are 
patched now, and I re-flashed it.  However in the meantime, it grabbed a 
new DHCP lease @ 44.24.241.55.  We should really give it a static 
IP/lease + DNS entry so it stops moving around...
