Magnitude X8 X-ray Flare of Sept 9 2017 (2nd Biggest in Cycle 24)
The sun erupted with an X8 solar flare, one of the largest of the current solar cycle (Sept. 10, 2017). Its source was the same sunspot region that produced an X9 flare last week. We show this in two wavelengths of extreme ultraviolet light at the same time, and each reveals different features. Both are colorized to identify in which wavelength they were observed. The coils of loops after the flare are the magnetic field lines reorganizing themselves after the eruption. The video clip covers about six hours.

Early Fall QRP on the Pemigewasset
There is a certain fragrance. The colors are shifting. The air is still except for the sound of crickets. It’s early fall on the Pemi. I stop at a bend in the dirt road and check out the giant pine tree for antenna possibilities.
I toss a line over an arching branch and pull up my 33 foot wire. I set up the KX3 on 20 meters. Now the sound of Morse mingles with the sound of crickets. Stations from Washington operating in the Salmon Run event are calling CQ.
I work six stations in a row and then switch to 30 meters. I call Jerry WA4FQN in TN. He gives me a 559 signal report and we chat for a while. Here’s my log:

You cannot imagine how precious these days are. They are the fleeting days of warm weather in New Hampshire. The hills and valleys soon turn to gold and orange and red. We are in a twilight zone before the cold of winter. The world is ours…. for a while.

FCC Opens 630/2200 Meters Amateur Band; Pre-Registration Required!

Yes, the headlines read, “FCC OPENS 630/2200 METERS TO AMATEUR USE AS OF OCTOBER 16, 2017; PRE-REGISTRATION REQUIRED.”
The FCC has authorized amateur radio use of the 630 and 2200-meter bands, effective October 16, 2017, providing registration procedures have been followed and no objections are received within 30 days.
The PLC (Power Line Communications) database is live and hams may begin registering immediately. They may begin operating on 472 kHz (630 meters) and 137 kHz (2200 meters) as early as October 16 if they register today and receive no objection in the next 30 days. Hams may not operate on the bands without going through this process.
Please fill out the UPC Form, today, to register your station, even if you don’t have any plans on transmitting on these new bands.
It is imperative that all amateurs register, even if they don’t plan to use these bands in the near future, as the FCC rules prohibit UTC (the Utilities Technology Council) from deploying PLC in these bands closer than one (1) kilometer from registered stations. Registration now will protect your ability to use our new MF/LF bands in the future.

Mount White: Easy SOTA With A Jeep

Mount White (W0C/SR-021) is 13,667 feet in elevation, just south of its big brother Mount Antero (W0C/SR-003) at 14,269 feet. Joyce/K0JJW and I activated this summit on SOTA using VHF/UHF. There had only been 4 activations of Mount White, which is a bit surprising. It is not that difficult to get to…if you have a decent 4WD vehicle. We have a stock Jeep Wrangler that handled the road just fine, but I would suspect that a AWD crossover (e.g., Subaru) or similar would not be adequate. We saw a number of hikers on the road (probably headed to Antero), so that is always another option.
The Mount White / Mount Antero area is covered with mining claims and old mining roads. This may degrade the hiking experience but does provide some decent 4WD roads to access the area. The Summitpost.org posting on Mount White has some interesting geological information about Mount White and Mount Antero. There are two summits on Mount White and Summitpost says the actual summit of Mount White is the eastern one. However, the SOTA database indicates the western one. Some other maps also indicate Mount White as the summit to the east but I believe the SOTA information is correct. I guess for SOTA purposes, it is correct, by definition.

A San Isabel National Forest map is very helpful for figuring out access to this summit. Basically, you head west on County Road 162 towards Mount Princeton Hot Springs. Eventually, you’ll get to FS 277 which is a moderate 4WD road marked as the road to Mount Antero. Take a left turn onto FS 278 and follow that uphill to eventually take a left turn onto FS 278A. Stay on 278A for a very short time, then take a right onto FS 278B which takes you to the saddle below Mount White. (See map below.) This route does require good vehicle ground clearance. There are two stream crossings and many tight switchbacks. All in all, it was an easy-peasy fun trip with our stock Jeep Wrangler.

The hiking route is not difficult: 0.35 Miles one way and 450 feet vertical. But you are above 13k feet, so expect the oxygen to be thin. We started out by following a road along the north side of the peak, then scrambled up the talus to the summit. There are bits of pieces of “trail” but we did not find an established hiking route. The day we were there in September it was extremely windy so we did not stay long.
Mount Antero is close by so you could do both summits on the same trip, assuming the weather cooperates.

Scouting Jamboree on the Air
This past Thursday(well it was released last Thursday anyway), I had the privaledge of talking with Bill Stearns, NE4RD, about the Jamboree On The Air/Jamboree On The Internet (JOTA/JOTI) that is coming up next month.
If you don’t know what JOTA/JOTI is, it is an annual event put on by the Boy Scouts of America in the month of October. It allows scouts from around the world to get on the radio and talk to other scouts from all over the globe, propagation permitting of course.
