Thanks for the suggestions. First, I tried the SH/DX approach. I normally use DX Summit for spots, but got a series of "Transfer Aborted" error windows when choosing Show/DX Call in the Packet Window . I assumed it has to do DX Summit not being aTNC or telnet site which accepts an SH/DX command. So I tried connecting to a telnet site. This approach was successful, but only for calls that had been spotted on that cluster.
Next I tried the Master Lookup Window using the standard DXWIN.MAS1 and .MAS2 membership files provided through the AD1C Updater program. I got call sign matches, but could not determine whether they were LoTW, eQSL, or Super Check Partial members. I assume a call sign shows in the Master Lookup Window if it is in any of these lists. To use this approach for determining LoTW membership, do I need to eliminate the eQSL and Super Check Partial members from these files?
