[Dxbase] sh/dx command

[Tom Lewis]

I have been looking for stations operating in the National Parks On The Air. The original Pavillion Packet Cluster software allowed this command, 
SH/DX 'NPOTA'.  The packet cluster would search the comments field and return spots with that comment. The current internet cluster that I am connected to doesn't support it. Does anyone know of any packet clusters on the internet that supports the comments field search?
ThanksTom, N4TL
