[Hammarlund] SP-600 VLF-31

[Ken]

The two I had were gifted to me from the estate of one of my quite early bosses who did VLF propagation research. He also had several Collins R-389s.I thought the SP600 VLF -31s were excellent VLF receivers.If it hadn't been for our family badly needing money at that point in our lives, I would have kept at least one.I did manage to keep one of the R-389s.Ken W7EKBSent via the Samsung Galaxy S21 5G, an AT&T 5G smartphone
