For example, I started with a 4 digit counter using nixie tubes and ended up with 7 digit 7 segment LED counter summing the BFO, VFO and HFO. I also later added the keyer and CW audio filter and so on\u2026..<\/b><\/div>\n<div class=\"MsoNormal\"><\/div>\n<div class=\"MsoNormal\"> <b>Other than the outer cabinet from LMB, I did all the metal work complements of the metal shop at our lab at CDC\u2019s advanced design lab.<\/b><\/div>\n<div class=\"MsoNormal\"> <b><br \/><\/b><\/div>\n<div class=\"MsoNormal\"> <b>Pictures show bottom with RF bottom plate installed and bottom view of RF section with plate removed.
