[Skimmertalk] skimmer server crash

[N4ZR]

I don't know whether this is related to your issue or not, Dave.  But 
here's my situation:

I have one RP-16 running perfectly with one CW Skimsrv.  I take the SD 
card out of that unit and put it in a second RP-16, identical to the 
first in every respect except for the MAC address.  I connect to the 
second RP-16s Console and can see that Linux is running, but the 
sdr_receiver_hpsdr has not started.  Why would it autostart on one RP-16 
but not on the other?  Is there something on the SD card that makes it 
specific to the RP-16 it works on now?
