|Grabulator I - Live Lowfers|
Periodically refreshing spectrum-vs.-time display, usually once a minute, as captured by 'Argo' . Most typically it is activated when a significant LF operating event (e.g. Transatlantic tests, 'Lowfer' 185.3kHz 'watering-hole' activities etc.) are underway. 'Argo' is the premier tool for rendering visible very-low-speed Morse code (QRSS) with dot-lengths of between 3 and 120 seconds (QRSS3 - QRSS120) and sundry boutique modes such as HELL. Depending on the expected signal format, the above 'Argo' screen can represent between a couple of minutes and a few hours of captured time; refresh time will likely change accordingly also. The entire 'Argo' display is shown, since much valuable information for aiding interpretation is on there.
