20190525 - Operating Portable from a Beetle

posted May 24, 2019, 6:35 PM by Onno Benschop   [ updated May 24, 2019, 6:35 PM ]

As Charles puts it: "This is not your old man's Beetle"

My "mobile" shack:

KX2, Hardrock 50 amp, Bioenno 12 Ah LiFePO4 battery with Powerpole distribution board held on top by Velcro. Antenna this day was a 20m 1/4 wave vertical ground plane, and inverted V for 40m up about 3m at the apex. Macbook Air using the contest logging to handle the CAT control, repetitive CQ, and replies for rapid “contest mode” exchanges.

10m long whip on top of the VW.

My favorite configuration at a picnic table. Antenna is lofted with the 150g lead weight seen just in front of the amplifier. I use “mason’s line” to put up my antenna wires. The bright pink makes good contrast with greenery. It is very strong.

20190525 - F-troop Noise

posted May 24, 2019, 6:22 PM by Onno Benschop   [ updated May 24, 2019, 6:23 PM ]

Before F-troop started today there was lots of noise on the 2m band. Attached are two audio recordings and a video of the band-scope of my radio.

Comments and suggestions welcome: cq@vk6flab.com
  • #3, audio while VK6RLM was disconnecting from the various links.
  • #4, audio with various modes.
  • Video of the band scope
I also tuned around with SSB, but that didn't give me any more information, the signal was the same across the whole range from 137 - 164 MHz.
