February at Potter Place
Dave K1SWL, Tim W3ATB and I met for lunch and then went to operate at the old rail station in Potter Place. I worked 8 stations including Belgium, Portugal, Spain and France.
I set up the KX3 under the eaves of the station on an old luggage box. I tossed my antenna line over the semaphore signals attached to the station. (See the last photo.) The place was covered with snow, and it was 43F.
I started off working Joe W1FYL at a campsite in Kissimmee, Florida. We had a nice chat then I tuned down the band. The DX was surprising. Here’s my log:
15 Feb-18 1818 14.043 W1FYL CW 599 599 FL
15 Feb-18 1859 14.008 ON4UN CW 579 599 Belgium
15 Feb-18 1902 14.010 CS0RCL CW 599 599 Portugal
15 Feb-18 1903 14.012 EA8URT CW 599 599 Spain
15 Feb-18 1905 14.022 EA5KV CW 599 599 Spain
15 Feb-18 1914 10.112 F5NTV CW 599 599 France
15 Feb-18 1915 10.116 N2CX CW 579 559 NJ
Meanwhile Tim had tangled his line in a maple tree above the picnic table across from the station. His water bottle dangled from a branch just out of our reach. It was a three stooges movie in progress as we struggled to retrieve the bottle. We borrowed a garbage can from the station and turned it upside down. Dave had a shovel in the back of his truck and Tim (standing on the upside-down garbage can) managed to snag the errant bottle with the shovel. But not before previous efforts failed with me sitting on his shoulders. (Fortunately not captured on camera.)
Tim and Dave worked half a dozen stations including Joe N2CX who was at Fort Mott in New Jersey doing a park activation.
Let’s Call CQ – QSO Today Episode 184 with NW7US
I got a Skype call a few weeks ago from Eric, 4Z1UG–the creator and host of the QSO Today Podcast–during which he asked me about how and why I got into amateur radio. Here’s the result.
Eric writes,
We talk a lot about the band conditions due to the Sunspot cycle. Most of it on Facebook and other places is about how “dead” the bands are at this point. We all can’t wait until the cycle starts to rise and we will be making contacts with little effort. I remember in my conversation with Chuck Adams, K7QO in Episode 58, that he really enjoys operating is “Pigrig”, one watt, CW transceiver on 20 meters. When I asked him, (I liberally paraphrase) “but Chuck, the bands are dead. How does that work for you?”. His reply was that while most hams are listening to the bands, he calls CQ until he gets a reply. Works every time.
My QSO this week is with Tomas Hood, NW7US, who has years of expertise in propagation and Solar activity. He is the propagation editor of more than a few radio magazines and websites. In our post-recording conversation we discussed this phenomenon of listening and not calling CQ. I even had this idea that maybe one of the reasons that the digital modes are so successful is because they “beacon”, as part of the whole digital experience, the same as calling CQ. This is why they make contacts. From what I see, looking at PSK Reporter, hams are making lots of contacts worldwide using the digital modes. While SSB may not be working so well, CW and the digital modes seem to work fine.
I like to work on my bench or make the podcast while listening to the bands. Jeff Damm, WA7MLH, in Episode 177, says that he will put his keyer in CQ mode while he is working on a new radio. Invariably, sometimes after many minutes, he gets a reply. Great idea Jeff!
73,
Eric, 4Z1UG

Highlights of Episode 184:
Tomas Hood, NW7US is the propagation editor of a number of shortwave and amateur radio magazines, and has a wide variety of websites, that grew out of his love for all things radio, and for listening on the bands to far off DX and commercial broadcast stations. Tomas shares his understanding of propagation and the lessons we can learn from listening, really listening to the QSOs and exchanges during contest operation.
All of the QSO Today episodes are great. I enjoy hearing about many different hams. Do check out all of the episodes that Eric has published.

NBC Report Features Hawaii Hams Preparing for Nuclear Attack

“In the case of an electromagnetic pulse from a blast, 90% of people may be without communication and ham radio is actually one of the ways that you’ll be able to hear what’s happening.” That’s the report that NBC News correspondent Jacob Soboroff gave just moments after the nuclear all-clear was given during the recent scare in Hawaii.
Check out the great 8-minute video below featuring Hawaiian hams and how they’re preparing for the unthinkable in one of the most beautiful places on earth.
