I am trying to help a friend build the Kenwood computer interface
described in the QST article but am having no luck in locating
the NEC PS2501-1 optoisolators that are shown in the schematic and
don't really want to pay a second source dealers price.  Does
anyone know of a suitable substitute part or have a data sheet
on the 2501 that I could use to find an alternate part?  Maybe
someone knows of a different circuit that uses different parts?
His rig is a TS450S/AT.  Any help would be appreciated.

Thanks,

Anyone know of a Web or FTP site where I can get the rules, operating times,
scoring, etc. for the CQ WW SSB contest?
Thanks!

Thanks to all! Many sent me the ftp://ve7tcp.ampr.org address, and a 
couple even e-mailed the file!
Thanks again, see y'all this weekend! Eric
