At the recent October Chew & Chat meeting Tim Kreth, AD4CJ, gave an interesting talk introducing members to WSPR and the WSPRlite. The presentation included discussion on using WSPR to learn about HF propagation, the WSPRlite and related resources. Tim also discussed the calculations necessary and presented a spreadsheet tool useful for converting WSPR signal levels to a relative approximation of what might be needed for other modes such as CW or SSB. The presentation and the spreadsheet are available via the links below:
