Scanners can be fun.

"What does a scanner see? Into the head? Down into the heart? Does it see into me, into us? Clearly or darkly? I hope it sees clearly, because I can’t any longer see into myself. I see only murk. I hope for everyone’s sake the scanners do better. Because if the scanner sees only darkly, the way I do, then I’m cursed and cursed again. I’ll only wind up dead this way, knowing very little, and getting that little fragment wrong too. "

Yaesu FT-980 Demo

Playing around with the Yaesu FT-980 I have been working to restore. These are great rigs from the days when every function had its own knob or button, and there were real meters instead of LCD screens. This radio has a very low noise floor and sensitive receiver, which rivals any other rig I have owned. Hopefully it holds up as parts are getting near impossible to locate anymore.

Horus 9 Balloon… on the way down

This video was taken on Saturday 23rd October 2010. I was set up on a hilltop monitoring the amateur radio experiments on board the Horus9 balloon. Carried aloft was the tracking computer, a cross band 2m/70cm repeater, a simplex parrot repeater on 2m and an APRS tracker on 2m. The launch coincided with the WIA National Field Day and the cross band repeater was very busy with field day stations making contacts. In this video you can see the Dl-Fldigi software decoding the telemetry from the balloon, the decoded telemetry was then uploaded to the tracking server via a WiFi internet connection.

Ikelite Autoflash AF35 Kit, Left Hand Flash Kit with Single Tray Guide # (ISO 100) feet: 28 Surface, 16 Underwater Reviews

Ikelite Autoflash AF35 Kit, Left Hand Flash Kit with Single Tray Guide # (ISO 100) feet: 28 Surface, 16 Underwater

  • AF35 AutoFlash’s advantages over using camera’s built-in flash:
  • Auto & Manual Flash Settings
  • Enhanced Color
  • Brighter Flash Output
  • Reduced Backscatter

Power The camera’s built-in flash is only about one-third the power of the AF35; its effective range is about 18 inches (0.5m).
