Completed Activated All RI Parks During Work All RI POTA Event

I started working POTA right before the pandemic, and have continued on.  I had managed to work 51 of the 52 parks in Rhode Island, and had activating Block Island as my goal for 2022.  Things didn’t work out last year, so it went back on the list of goals for 2023.

My club, Newport County Radio Club, decided to sponsor a “Work All RI POTA” event from September 6 through the 10th.  Prolific activators from all over the country descended on little RI, to activate all 52 of our parks.  Thanks to some incredibly wonderful assistance from Willy W1LY, a fellow club member, we planned to activate Block Island on September 7th.

For those not familiar, Block Island sits in the Atlantic Ocean, about 15 miles south of Rhode Island.  Unless one is an Olympic Swimmer, folks usually take a ferry from Point Judith to Old Harbor.  The trip is 19 miles by sea, and takes almost exactly an hour from dock to dock.  As a reference, a round trip for a full size van/truck and two adults is about $140.  Book weeks in advance during the summer to ensure you get a reservation.

Willy picked me up in his camper van (all the comforts of home, except for a water closet) at 6:40 AM, as vehicles are required to arrive at least an hour before departure time.  We were underway about 8:30 AM, and at the dock on The Block by 9:30.  For those RI natives, we know that there are many 100+ year old hotels and homes on the island.  Sadly about two weeks ago, the Harborside Inn burned.  This is what greeted us as. we were waiting in line to leave the ferry:

Prior activators of the Block Island National Wildlife Refuge (K-0513) complained of difficulty finding a place to access the refuge, which isn’t surprising as it was made for animals and not people.  Most would go to the town transfer station, near the northern tip, and activate from that parking lot, but it was never clear that the parking lot was actually within the park boundary.  Some map sleuthing indicated that there was a road that cuts right through the middle of one of the sections of the park (the park is made up of a bunch of isolated sections, not one continuous piece of land).  I’ve included a section from the US Fish and Wildlife map below that shows that Skipper’s Island Road, a left turn off of Corn Neck Road, passes through the refuge (slate blue color). The road is made up of crushed sea shells and is in good shape, probably because it services a few homes.

Sure enough, we caught the attention of some of the wildlife:

We were set up and making contacts by 10:15 AM local time (14:15 UTC).  Willy W1LY was on 40 meter SSB using an end fed wire in an inverted-V configuration held up by a jack-kite pole.  I ran 20 meter CW, feeding a mag-mounted 17 foot whip on top of the van.  We had a dry run the prior weekend at another park and were pleasantly surprised to find that we did not interfere with each other, despite the antennas being within feet of each other.

We took a lunch break in the middle and swapped bands.  When we wrapped things up at 1:45 PM, we had just enough time to get back to the ferry dock by 2 PM.  Willy had 104 Qs on SSB, and I had 52 on CW.  As we were waiting to board the ferry for our 3 PM departure, there was another reminder of the tragic fire – demolition equipment was being offloaded from the ferry.  By this time next week the Harborside Inn will be nothing more than an empty lot and fond memory.

Thanks to Willy W1LY, I’ve now activated all the parks in Rhode Island!

POTA Hunter Award for 1000 Parks

I just received confirmation that I have 1,000 unique parks confirmed as a hunter.  That was also one of my goals for 2023.  At this point I only have one goal left: To build my QDX Digital Transceiver and get it on the air.

In terms of POTA, I have found that the confirmation rate is a bit low.  According to my log I’ve worked about 1,500 unique parks, but only 1,000 of them have confirmed.  That matches up pretty well with my LotW confirmation rate.

CWops CWT Silver Medal Achieved

As of early yesterday morning (3 AM), I completed CWT #90 on the year.  This earns the Silver Medal (which I achieved my first year).  I need 30 more contests to get to 120 and earn the Gold Medal (which I achieved last year).

The past few weeks, propagation has been so good, I have been getting up at 3 AM to participate in the 4th contest of the week (Wednesdays at 1300Z, 1900Z, 0300Z, and 0700Z).  But at this point, I think perhaps I will just do 3 a week and skip the 0’dark hundred one.  By the end of September I should be at 120.

Solar Cycle 25 now out of prediction bounds…

As I type this, my side of the planet has undergone a sudden R2 radio blackout due to a M 6.8 solar flare.  Sadly no 40/20/15 meter contacts for the next few hours.

As I was confirming the flare, I checked up on the Solar Flux Index for Cycle 25, and discovered we are now well outside of the upper predicted limit for the cycle.  This is making our HF work both challenging (like today), and fascinating (a few days from now when the ionosphere calms down).  I’ve been enjoying world-wide DX at night recently, something I haven’t seen since 2012.

POTA Hunter Award for 900 parks

Yesterday I received confirmation for park #900 ().  This puts me closer to one of my goals for 2023, working 1000 parks.

My goals for 2023 are:

  • Teach a class (either Technician or CW Academy)
  • Participate in 120+ CWTs for the CWops Gold Medal
  • Build my QRP-Labs QDX Digital Transceiver
  • Activate 10 new parks in CT or obtain award for hunting 1000 parks
  • Obtain 50 States Parks on the Air award

So two out of five have been completed.  At the half-way point for 2023 I have 80+ CWTs under my belt, so as long as my antenna stays up and I can continue to find my way down to the basement, I should be able to complete that one.  At risk is the QRP-Labs QDX Digital Transceiver kit – I need to get that done!

Gold medal for 2022 CWTs

While I was taking the advanced CWops classes I started participating in their weekly CWTs (short one hour long CW sprint contests).  For the 2021 year, I finished with a silver medal (meaning I had participated in at least 90 contests).

For 2022, I participated in more than 120 contests, which earned the gold medal shown below.  (At the half-way point of 2023, I have completed about 80 contests so far).

Thanks to CWops for their excellent education programs and for sponsoring four CWTs every week!

Meanwhile, quality LiFePO4 batteries last and last and la….

After reporting the failure of my Miady 16 AH battery (lightly used less than 3 years old), I dug out my “backup” battery: a 9.6 AH K2 Energy battery, purchased in mid 2011.  That battery is 12 years old.  It had not been recharged since December of 2021 (2.5 years ago).

I used my battery analyzer to do a simple constant current discharge and found the battery had a capacity of 8.7 AH, even after self-discharging for 2.5 years.

So there is clearly a difference between a quality LiFePO4 and a cheap one.

Spoke too soon re: Miady 16 AH LiFePO4

After “fully” charging the battery, I put it into service during a POTA activation.  Imagine my surprise when 10 minutes into the activation my radio shut down.  I suspected a battery failure, but didn’t have a backup with me.

When I returned home, I discovered the battery was producing 0 volts, exactly as if the BMS had shut the battery down.  My reasoned guess is that the battery cells were not balanced, resulting in a protective shutdown.  So I “fully” charged the battery again, allowing it to stay on charge for about 4 hours.

I set up a test with a 6 Amp draw to check on the battery capacity this afternoon.  Just like during the activation, the battery was fine until about 12 minutes into the test, when it simply shut off after supplying about 1.2 AH to the load.


My suspicion is still that the battery is badly out of balance, and many hours of “trickle” charge are going to be required to restore operation.  But it is entirely possible that one of the cells has failed.

Note, this battery sat unused in my house (so room temperature) for about 5 months after being fully charged.  It was not abused in any way, and had less than 100 cycles on it, never drawing more than 50% capacity.  The battery itself was produced in late 2021 so it is about 2.5 years old.

Self-discharge Miady 16 AH LiFePO4 battery

Back in 2020, I purchased an inexpensive 16 AH LiFePO4 battery from Amazon, made by Miady.  Initial testing indicated that it was optimistically specified, as it tested to be 15.24 AH, but that wasn’t bad given it was about a third the usual price.  I wound up using that battery as my primary power source for many POTA activations over the next two years.

The last time I charged it was on December 20, 2022.  Giving it a full charge this morning, I found that 0.357 AH was required.  So the battery had self-discharged 0.357/15.24 or 2.3% over a period of 158 days.

Just goes to show how low the self-discharge of a LiFePO4 battery is – about 5% per year!

Thanks to Rob KD1CY for another SKYWARN class!

Rob KD1CY gave another SKYWARN class on May 13th.  That happened to be the 5th one I’ve taken (2011, 2012, 2014,  2018, and 2023), so that’s an indication of how good they are.

Many folks don’t  realize that federal disaster relief funds are only released to counties after there has been “ground truthing” of things like snow totals.  In other words, a blizzard that is forecast doesn’t “officially” happen until a trained weather spotter sends in the data.

Thanks to all that took the class as well and are acting as the eyes and ears of the National Weather Service  here in Rhode Island.
