[Dxspider-support] Raspberry Pi DXSpider Node

[Bill Shell]

Keith & Dave,

Thanks for your responses.  I have had the N6WS-2 DXSpider node 
operating on a RPi since the shortly after the release of the Raspberry 
Pi Model A (256M).  It has been rock solid for two years. My concern was 
with a higher resource loading on the W6RFU node with 40 users and 4 
node partners.  It has been operating for about a week, and everything 
has been operating perfectly.  We just converted the W6KK DXSpider node 
over to a RPi today, and it is also doing fine.

TU es 73,
Bill
N6WS
