2025-11-29 US-8878

I activated US-8878, State Game Land 181. It’s my 39th unique park activated on my way to the next award at 40. I made 11 FT8 contacts at 2-4W with my speaker-wire doublet pulled up into a tree. I had extended the length to 44ft length per some online recommendations.

The battery was low on my little Evolve 3 laptop, and I wanted to charge it from LiFePO, but it wouldn’t charge. It turns out that I had inserted the barrel adapter into the headphone jack instead of the tiny power port. The laptop had died at 9 contacts with 3 people calling me, so I switched to my other laptop to finish up.

10M tuned OK, 40M tuned OK, and 20M tuned easily, but with both laptops, the radio would drop the USB connection immediately upon transmitting. I may need to add a current balun between the radio and matching transformer.

CQ WW CW 2025

For this year’s CQ Worldwide CW contest I heard KH6J from Hawaii on 40M, but I couldn’t contact them. Locals weren’t worth anything except for unique CQ zones as multipliers. I kept it to 5W and made 20 contacts on CW. I turned up to send 25wpm, since everyone was going so fast.

I still rely on the excellent decoder in the R1CBU radio UI, but I’ve been practicing reading CW too.

US-1418: 2025-10-30

I ran out to Sam Lewis, US-1418, to activate when the rain stopped.

I took a few minutes to setup my normal EFHW running North-South to operate more to the East and West, though I did get a contact to Colombia.

I operated mostly low-power FT8, 1-4W, but mostly 2W. I chased and got 1 CW contact before it started getting cold and dark.

US-8834

I played a little FT8 at US-8834, State Game Land 136, with only 2W on my 40M EFHW in an inverted-V. I made 26 contacts, and looked for some CW, but barely heard anything.

US-4356

I headed to US-4356, Boyd Big Tree Preserve for an activation. I took my time and med 51 contacts: FT8, FT4, 2 SSB, 2 CW. I stretched my 40M EFHW from pavilion to tree to the East. A bystander hung out for 40 minutes to see what I was doing, so I showed him around the bands.

US-4567

I activated the Conoy Wetland along US-4567. I used the 40M EFHW running to the South East. I stayed on 40m, using FT8 and 4W. I got my 30+ contacts calling CQ POTA, and didn’t chase anyone.

I experimented with the counterpoise:

  • I saw 1.5:1 SWR with the counterpoise coiled up.
  • I saw a lower SWR with the counterpoise unwound.

ARRL Field Day 2025

I operated the last 3 hours of ARRL Field Day. My station was at home on emergency power and QRP, so 1E class. I made 50 contacts so that earned me 650pts.

US-1139 Chino Hills

I activated Chino Hills State Park, US-1139, twice while in Los Angeles. I hiked in 1.5 miles for one activation, and biked half way up one of the hills 5 miles for the second.

Broken EFHW

The home antenna wire comes down every once in a while. I soldered and re-hung it, and it looks good. It seems to need a little power put through it, and then the SWR looks good. I wonder if some static accumulated, and that is causing higher SWR for a moment.

US-4361 King's Gap

The activation at King’s Gap Environmental Education Center, US-4361 was tough-going, even though I was at the top of the mountain. I used the GRA vertical whip with tapped coil. Internet access flaked early, so successfully spotted myself on APRS with APSPOT.
