✇W2LJ QRP - When you care to send the very least!
QRP - When you care to send the very least!

I've decided to make the 4States QRP Group 4S-Tuner the official tuner of the W2LJ QMX Portable Ops bag. So I ordered another one for the shack for when I use the HW-8.  This way, I don't have to keep transferring the one I have back and forth between car and shack.

I really, really like the function of the two LEDs.  Great design feature by David Wayne Cripe NM0S!

When the red one is bright and the green one is out, the SWR is too high. When the two LEDs are of equal brightness, you have a 2:1 SWR. When the green LED is at max brightness, and the red LED is at minimum brightness or out altogether, your SWR is around 1:1.


This is a T-Match Tuner and I find it a bit easier to use, having the inductor in the circuit. Nothing against the ZM-2 as it is a wonderful little unit and will stay in the KX3 bag, should the autotuner fail for whatever reason. But sometimes, I just have a bit of trouble getting that single red LED to dim. I guess it's range is just a little narrower than the 4S-Tuner.

I already know it works well with my KM4CFT EFRW antenna. This weekend, time and weather permitting, I'd like to see how it handles the AX1 from our patio tabletop - a simulated POTA activation. Have to practice, just like the astronauts did! HI HI !

Onto another subject, with all the CMEs and solar flares that have been occurring the past few weeks, I saw this photo on Facebook, taken just yesterday, from the 1,000 Islands region in Upstate NY.


Marianne and I are heading up there soon for some away time for our Anniversary - I know I've mentioned that before. Will this finally be a good chance for me to see the Northern Lights? I hope so! If I'm lucky enough, I'll try to get some photos.

While I'm on the subject of photos - here's a neat one I came across the other day, for the QRP Image of the Day. This was posted on Facebook by  Chris Farnham W1YTQ.  He was camping with his son's scout troop in Boston Harbor Island up in Massachusetts and one of the licensed Scouts actually accomplished his first POTA activation. Later, after the hustle and bustle of the day was over, Chris decided to stroll on down to the beach to activate - Boston Islands Park - US-2421, himself.


Isn't that a beauty of a shot? The moon and it's reflection on the water, the KH1 with the antenna sticking up, and that cube-ish  lantern. What a great mood shot! And once again, it shows that you don't have to tote around a whole mess of equipment to have a good time!

Updating MagTag WX for OpenWeatherMap API 3.0

✇WB4SON

A couple of years ago, I put an Adafruit MagTag Weather display together.  The MagTag was a fairly inexpensive CircuitPython device with an eInk display and built-in WiFi.  It used a free (at that time) service called OpenWeatherMap API

Within the past month, OpenWeatherMap changed their policy and now requires a credit card to validate the API key, but they still don’t charge for up to 1,000 API calls per day.  Their interface allows you to set restrictions on the maximum API calls per day (it defaults to 2,000).  In my case I set it down to 500, so I never have to worry about a software bug causing me to get billed.

The code.py program that Adafruit supplies currently, is out of date, as it uses the API 2.5, which has been replaced by API 3.0.  The change needed to the source file is trivial – simply change the line that has the 2.5 reference to 3.0 and you are all done.  Like this:

URL = “https://api.openweathermap.org/data/3.0/onecall?exclude=minutely,hourly,alerts”

Note: I had edited the original bitmap background image to add my call on the top line.
