I overheard some tips from Tom, KA3TKW, on the 21 repeater: Check out the AMSAT manuals for contacting satellite repeaters, and operate full duplex, so you can hear while transmitting.

My Week in Radio

Contesting

I finished the FT Challenge. There was no special exchange this year. We could use other defined subbands in addition to the regular frequencies to alleviate crowding. We could work anyone, even if they’re not participating explicitly.

I operated QRP, so it was nice to find the quieter subbands and more FT4 activity. You earned multipliers for each 3000km, so I don’t really know on my score yet.

I found wsjtx-improved on the Debian Linux repository, so used that. I saw the color improvements, the better location labels with states, and it had filters.

AllStar

I learning some obvious things about AllStar: it can’t hear my DTMF if it’s currently transmitting, since it’s simplex, so it’s hard to control on a busy net.

Yagi in the Wind

Finally, I watched my home-built yagi flapping around on that windy day. I guess I can stop worrying about it, since it held up fine.

My Week in Radio

• I used N3KZ 440 repeater in York from Lancaster
  • always surprised on their range.
  • thought UHF didn’t go far.
• I built an Allstar node from a PI 4 and a USB-C radio dongle to reach a fringe repeater.
• I’m looking forward to FT challenge
• I stumbled into and recognized some Olivia-8/250 on 20M, and some SSTV
• I’ve been hearing lots of ISS repeater traffic at convenient times on my good ol’ 1/4 wave antenna in the tree.
• I got the radio blog up-to-date with all my adventures.
