KØBX Joe has some very helpful information, especially for the Kenwood TS-850, and AEA PK-232MBX.  If you operate RTTY, then chances are you know Joe.

WØMA  This is the Boeing Employees Amateur Radio Society - St. Louis website.  Lots of information on the clubs activities, including monthly newsletters, contest participation, etc.

Writelog I've been using this software for about two years now and it is very effective in contests, especially CW and RTTY.

RS-232 Adapters  I bought a very nice one from this company.  It connected very easily.  I will use it for rig control in the next contest CQ/RJ WW RTTY DX.
