Blue Sky Preparations

The song might say “Nothing but blue skies from now own”, but we can’t depend on that in New England.  Our peak hurricane season still has a few weeks left, and storms like Hurricane Sandy (October 29th) remind us to always be prepared.

Today being the first blue sky day in a bit, I decided to make sure my Honda EU2000i would start.  I purchased it in 2011 (Hurricane Irene took our power down for several days after the generator arrived – whew!) and it still runs perfectly.  However, “running” doesn’t include starting, and it has been difficult to start the past half dozen years or so.  Even a trip to the Honda Service Center didn’t fix things.

I always suspected it was a fuel issue, and was preparing to shoot some starter fluid into the carburetor.  But I found the generator covered in dirt and grime (it sits next to the leaf blower and lawn mower).  So I turned the fuel on and went about cleaning the outside for 20 minutes or so (it really was a sticky mess).  In tilting the generator from side to side to get to the spots on the bottom, I notice a bit of fuel leaked out of the overflow pipe.  I cleaned that up, started to give it a big pull, and about half-way through it, it sprang to life!  This is the first time in years I haven’t pulled my arm out of the socket trying to start it.

My assumption is it simply takes quite a long time to fill the carb via gravity feed.  So from now on, I’m going to turn on the fuel knob and let it sit for 15 minutes before trying to start it up.

My 2nd POTA Activation in Maine

My family planned on being in SE Maine for several days, and I figured I would attempt to activate a park near where we were staying (not many to be found, actually).  I wound up going to Ferry Beach State Park (US-2388) on Sunday.  I had checked out the park online prior to going and saw only 32 activations at the time.  When I got there, I suspect the reason might be the $6 fee to enter the park, which was delightful.

Because my family was with me, it had to be a quick on-and-gone activation.  I was on the air about 2:45PM local time and 14 minutes later had a dozen contacts.

Burned by an Old Plugin

WB4SON.COM (this website) runs under WordPress.  I have been receiving a warning for months that my PHP version was out of date (PHP is a scripting language used for web development).  I figured I would go ahead and update it to the latest version.  Unfortunately, when I did, my website crashed and gave me a critical error message.

I had recent backups so I wasn’t entirely panicked, and had always had good luck with the Customer Service folks at my hosting provider.  Unfortunately I wasn’t able fix things myself, but customer service was able to do it for me.  Essentially they disabled all the plug-ins my website was using – the usual reason for a critical error is a plug-in that hasn’t been updated and won’t support a newer PHP version.

Sure enough, when I checked the error log, one plug-in, called Sunrise_Sunset, was failing and was the source of my problem.  Needless to say, I deleted it.  I also deleted two other plug-ins that I was no longer using.  Thankfully my website is back up and running the latest version of PHP with no errors now.

Moral of the story: Get rid of old plug-ins that might no longer be maintained.

Incidentally, disabling the plug-ins, a critical step in getting my site back up and running, meant that Akismet Anti-Spam was no longer protecting my website.  In the 15 minutes or so that it took me to get rid of the bad plug-in and enable the good ones, my website had been pounded with spam comments, the vast majority coming from Russia.

Beware Puffed LiPo Batteries

Back in 2021, I was working with a young ham looking to learn Morse code.  As he was blind, many of the tools commonly used, were not as useful.  I stumbled upon the Morserino-32, a wonderful device from Willi OE1WKL, I bought a pair of them in kit form, and soon had my young fella sending and receiving Morse.

Recently a somewhat older ham (about 70 years older than my young student) mentioned he was having issues transitioning from CW skills learned on a bug decades ago to modern paddles/keyers.  I immediately though of the “Echo Trainer” mode in the Morserino-32, which had been boxed up for the past 5 years.  Upon examining one of them, I discovered that the 3.7v LiPo battery had “puffed”.  This is a sign of a failed battery.

Since many ham devices use LiPo batteries, I thought I would remind folks to beware puffed batteries.  It is quite dangerous to attempt to charge and use them.  The photo below shows the puffed battery on the left (leads cut off since it can’t be used) and a “normal” battery on the right.  If it looks like a pillow, it is time to dispose of it safely & properly.  Both Best Buy and Staples offer battery recycling for free.

IC-7300 Stuck in USB-D?

Yesterday, I headed out to activate a couple of RI parks.  I hadn’t used my IC-7300 in a few months, and the last time I was running FT8 at a POTA demonstration.

I intended to run SSB, which tends to have more potential hunters, but when I set my rig up at the first park, I could only select LSB or USB-D on 20-meters.  I tried all sorts of combinations of button/screen presses with no luck.  So I changed things over to CW, and completed my two activations. (Yet another story trying to find a 1/8 to 1/4 adapter for the paddle).

Today I fired the rig up again, and discovered the “magic” button combination.

  • On the main screen, pressed the Mode button (which was showing CW) – that opened the screen below
  • Pressed the SSB button (which toggled between LSB and USB-D, leaving it on USB_D
  • Pressed the DATA button, which changed USB-D to USB

Gold Medal for CWops CWT Participation

Ever since I joined CWops in late 2021, I’ve been participating in their weekly CWT (CW Contest).  There are 4 potential ones on Wednesday and Thursday UTC (9AM, 3PM, 11PM, and 3AM local time).  I usually do 3 a week and it is rare for me to miss one unless I’m traveling or dealing with medial stuff.  I just received my third Gold Medal, which recognizes at least 120 CWTs during a year.  My first medal was Silver as I joined so late in the year it wasn’t possible to get to the 120 minimum.

My thanks go out to Rob Brownstein K6RB who has to coordinate obtaining and shipping out all the medals, and of course to everyone who makes CWops such a wonderful organization.

Technicians on 10-meter FT-8

Last month I gave a presentation to my club about getting Technicians onto HF using FT8 – My reason for going that approach is that their only HF allocation is on the 10-meter band, and investing in a modern radio can be expensive.  Fairly inexpensive QRP gear, like the QMX+, is fully capable of working FT8 when the band is open.  Also, antennas, like a home-built dipole, are inexpensive, and easy to deploy.

Oddly enough, club members were most interested in the QMX+ QRP rig, and several ordered the kits from QRP-LABS.COM

Here is a copy of the presentati0n

I spent much of the rest of July running my QMX+ on 10-meter FT8

Updating my QMX+ Firmware

I gave a presentation recently at my radio club (Newport County Radio Club) that was partially based on my QRM+ Transceiver; a nice kit, inexpensive, and easy to use with FT8.

My version was 1_00_27, pretty old.  The current version was 1_02_03, which has the newly supported SSB mode and took care of some other issues (See “Firmware” partially down the page here: https://qrp-labs.com/qmx.html ).

I had never updated the firmware before, and I will admit that the process is rather simple, but the manual “Section 7 Firmware Update procedures”, leaves some rather important details out.

To begin with, using the Menu button to find the “Update firmware” menu is simple enough, but it doesn’t mention anything about how to select it, or using the TUNE button to confirm it.  Once you do that, the screen goes dead and the Flash Drive appears on your computer (probably need to warn folks to have it plugged in before starting the firmware update process).

Once the drive showed up, it was as described in the manual, with an EEPROM file and in my case firmware 01_00_27.QMX.  Per the manual, I drug the new firmware 01_02_03.QMX onto the drive.  The manual said that dragging a new file would erase the old one.  That didn’t appear to happen, as I now saw three files.  But patience was rewarded – several minutes (3 or 4)  AFTER I drug the new firmware onto the drive, the computer beeped at me and said the USB Drive was no longer available, which was cryptic to say the least.

Losing the drive seemed reasonable, and I suppose it was the result of the new firmware loading.  However, there is no status indication to let you know what is going on.  I waited about ten minutes and the screen was still blank.  I unplugged and re-plugged the USB cable, and nothing was there.  I waited another ten minutes, and finally removed power from the QMX+, waited a minute, then plugged it back in.  At that point I could power the unit on as normal using the VOL knob, and it reported that it had the latest software installed.

The manual does says there are TWO ways to exit the firmware update mode.  The first is simply doing the update, and it claims that the QMX will automatically reboot in normal operating mode.  That did NOT happen in my case.  The second way is to remove power and apply it again.  That worked for me.

I have NO idea how long one has to wait after dragging new firmware onto the drive folder; Seconds, a minute, ten minutes?  But patience did pay off, as did the silent prayer when I cycled power after waiting about 20 minutes.

Pre-Field Day IC-9700 Calibration

Its that time of year again, when I do pass predictions for all active satellites prior to Field Day for my club in Portsmouth RI.  In addition, it is important to confirm that my rig is properly calibrated (uplink offset is adjusted) and it is working on CW and SSB.  Every year is different, of course – 2025 has 7 operational FM birds  (AO-91, AO-123, IO-86, ISS, SO-50, SO-124, SO-125), and 5 operational Linear birds (AO-7B, AO-73, JO-97, RS-44, MO-122)

Satellite AO-73, always problematic, was calibrated on June 23.  My thanks to KB2WNY for a SSB contact (nobody returned a CW CQ despite outstanding downlink strength).

My thanks to K2DH, K4YYL, on CW, and N2FYA on SSB for contacts on June  28 confirming RS44 was calibrated.

John, N2FYA was also on for a pass of MO-122 to help me verify another satellite on SSB.

I haven’t been able to contact AO-7 at all.  My only passes will be for SO-50 and AO-73 on Saturday afternoon.

Resilient Communication

For the last 4+years, I’ve been running a WinLink VHF Gateway on 145.050MHz.  WB4SON-10 is on 24/7 and has excellent coverage to the entire East-Bay of RI as well as the south coast.

WinLink is essentially an email system with global coverage.  The idea is to use RF to connect to a WinLink gateway station that has the ability to connect beyond your local area of coverage.  The gateway will forward your message via whatever path it has available.  My gateway is normally attached to a commercial internet service.  When things go sideways, the gateway remains on the air thanks to solar power and batteries.  At that point it can connect via a satellite link to span beyond a local impacted area.  If that isn’t working, it can use a HF link.

I purchased a StarLink Mini system that I can deploy in my back yard, or wherever I happen to be, as it allows “roaming” service connections.  At the time, the service could be enabled or disabled whenever necessary, for $50 a month.  I usually kept it disabled to avoid the monthly fee.  Recently StarLink started offering a different “backup” plan for $10 a month with a 10GB per month data limit (you can purchase more data for $2 a GB if needed).  Since WinLink is extremely efficient, it is almost ideal for that purpose.

My backyard is surrounded by large oak trees (perfect for deploying wire antennas on HF), but it is not ideal for a satellite based system.  Nevertheless, the StarLink Mini provided me with very respectable internet speeds, even when more than half the sky was obstructed.

The StarLink Mini Satellite dish deployed on my backyard deck – it is about 1 foot square, and runs off a plug in supply or battery power.

The blue area above is clear sky. The red areas are obstructed by trees, or my house. (the display spins around so you can see a 360 degree view).

Despite the obstructions, the StarLink Mini delivered 189 Mbps down and 8 Mbps up speed. Those speeds would be much higher if I had a clear sky view.
