#POTA Activation of JD Mac Arthur SP in South Florida
This, my second POTA activation, was a much bigger su
ccess (39 qso’s in an hour) than the first (a mere dozen), despite #2 being on a weekday afternoon vs. Sunday for #1. I attribute this to my savvy scheduling to avoid ARRL’s DX Contest and at the same time, ARRL’s respectful consideration for a Big Gun like me in not trying to compete! As the Borg said, “Resistance is Futile.”
The other big factor was getting a few hams to spot me on the clusters. I was quite surprised, and thrilled actually, to be the subject of a pileup for a few minutes. Imagine, lil’ ol’ me, being sought after; I hardly knew how to handle the fame!
Things started kinda slow, my first contact being a ham about two miles away; I’m thinking, oh boy, this’ll be a long afternoon. Will I ever get the requisite ten qso’s to count a POTA activation? I tried to spot myself but on Dxsummit.fi it is so awkward to do on your smartphone. With ten thumbs like me, mistakes are made. I did ask several hams to spot me and soon a few did, and then I was in demand, even at 4pm on a Tuesday afternoon. I never knew there were so many retired or unemployed hams sitting around bored during the day. From South Florida I worked hams in NY, CT, MI, PA, MN, AZ, CA, England and Spain!
I used my link dipole antenna up approx 24′ at the apex, set for 20m. By closing a pair of links, it can be reset for 30 or 40 meters. I built this antenna a while back, and tuned and trimmed it carefully for each of these bands, so no tuner necessary. I’ve tried a PAR EndFedz and a homebrew Buddipole for HF and this is the best for me, thus far.
From left to right: the dipole (made of speaker wire) rolled up on custom deluxe wire winder; middle, the handsomely crafted center SO; and right, the links for 30m, left open so antenna resonates at the shorter 20m cut. Note “stress relief” at the SO and use of safety pins to carry the tension of the dipole when hoisted. Below is pic of my antenna launching tool; it was too heavy at first so I drank half the contents. Also below is a pic of my tie down line, fluorescent builder’s twine. I’ve decided to be stealthier in the future and will change that out for something that’ll blend better.
I want to be stealthier so I don’t draw attention to my station and my suspicious behaviors. Even though I have a right to be there at a picnic table not all Park Rangers got the memo and some may think they should run me off. Last week a Ranger did stop by and I thought “well, here we go,” but actually he just wanted to chat; his Dad had been a ham, so I tried to recruit him. I had another visitor, too; note to self, don’t operate so close to garbage cans!
And finally, a note to the wise for operating out of doors in Florida; bring your bottle!

Weekly Propagation Summary – 2018 Mar 26 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2018 Mar 26 0143 UTC.
Highlights of Solar and Geomagnetic Activity 19 – 25 March 2018
Solar activity was very low. The sun was spotless and absent of significant flare activity. No Earth-directed CMEs were observed during the period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 19-25 March.
Geomagnetic field activity reached G1 (Minor) storm levels on 19 March and active levels on 23-25 March due to the influence of recurrent, negative polarity CH HSS effects. Quiet to unsettled conditions were observed on 20-22 March.
Forecast of Solar and Geomagnetic Activity 26 March – 21 April 2018
Solar activity is expected to be at very low levels throughout the outlook period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at high levels on 26-28, 30-31 March and 01-02, 12-21 April. Normal to moderate levels are expected for the rest of the period.
Geomagnetic field activity is likely to be at G1 (Minor) storm levels on 26 March and 12 April with active periods likely on 26, 29-30 March, and 11-15, 19, 21 April due to effects from multiple, recurrent CH HSSs. Quiet to unsettled levels are expected for the remainder of the outlook period.

The rise and rise of FT8
There is no doubt in my mind that FT8 has been phenomenal.
Every day this new digital mode seems to attract more and more people. It works with the briefest of openings and the software needed is free. It takes up about 60Hz only and works with weak signals. On a recent (rare for me) visit to 20m, DX from all over the world was spotted.
Even on 2m VHF, most days I spot signals from all over western Europe under flat conditions even with my omni antenna.
What will the Es season bring on 6m this year with this mode?

Hams pitch in to help as “Hat Trick” of major storms hit Northeast
WX1BOX volunteers were active for 17 hours straight, and afterward, some continued to monitor high tides and strong winds, which persisted into the weekend. The volunteers handled more than 1,000 reports of wind damage.

Which two-way radio service is right for you?
Choosing the right two-way radio can be confusing. You can’t just buy a couple of radios and start talking on them. Most two-way radio services require licensing of some sort, and radios designed to be used in those radio services must be certified by the FCC.
