Two options for a logging program include:
TPWINLOG - A Windows program designed by W4AXO specifically for the TPQSO event. TPWINLOG collects data for all 3 modes: Digital, CW, Phone. It can be used with a history file to automatically present the likely details for a currently-entered callsign. Its logfile output includes a filled-in summary sheet with the calculated score.
N1MM Logger+ - A popular program that has been configured for many different contest events. The link at the beginning of this paragraph opens a new page telling how to configure N1MM+ for TPQSO. If you use this program for logging, please submit your Cabrillo log file and include a filled-in TPQSO summary sheet.
