When I arrived back from Finland, I had a little package waiting for me that contained this:
This is a 60 KHz WWVB time receiver module and the associated loop antenna. I plan to play around with this as an alternative time source to a GPS receiver for syncing beacon signals such as is needed with WSPR. This was obtained from the good folks at PV Electronics in the UK. If anyone has any experience with these modules, I would appreciate any insights as I am going at it totally cold.
