Privacy and freedom are constantly traded in for a (often false) sense of security. This has nothing to do with ham radio, you’d probably think, but even our hobby isn’t immune.

Repeaters
Repeaters are only useful if the antennas can be placed high above ground. In the Netherlands we use a number of existing locations, most of which were once used for analog TV and radio. The owners of the towers decided that safety and security will prevail over (safe, terrorist-free) ham radio.

The following systems will be affected:

• ATV repeater PI6ATV, both analog and digital,
• 2 meter repeater PI3UTR,
• D-star repeater PI1UTR,
• DMR repeater PI1UTR,
• RX co-location for the 70cm repeater PI2NOS,
• RX co-location for the 10 meter repeater PI6TEN,
• Four Hamnet access points and links.

There is a chance that the equipment can be relocated to a lower section of the tower while keeping the antennas on the original altitude. Even in the best case scenario the costs of relocating will exceed the minimal financial reserves – good coax cable is expensive, and we would need a lot of it.

I’ll end with this quote: Those who would give up essential liberty to purchase a little temporary safety deserve neither liberty nor safety. (Benjamin Franklin)

As Brick also mentioned in in his last post about Anytone Tech: the reactions on the new models vary wildly. I think Brick said all there is to say, but I’ll add this thought:

– If a radio is cheap but crap, we complain, but buy it anyway.
– If a radio is good but costs more, we complain, but suddenly the price is all that matters.

Let’s see how these radios perform and at what price point before judging them. I know John of Miklor.com gets (or already has) review samples, and I’m on the list too. To give you some more insight in what these radios can and cannot do, here are some preliminary user manuals (PDF).

One of the great things about amateur radio is the number of different ways in which the hobby can be enjoyed.

For over a year now my health has been poor because a brain bleed in September 2013. Before then, I enjoyed QRP QSOs (mainly SSB), construction and field experiments from VLF to optical. Since my stroke I have been clumsy and (until recently) not allowed to drive. Very very slowly, normality is returning but I think it will be way into 2015 before I can call myself well.

In the meantime, I still manage WSPR and other digital modes from home. I can even, albeit briefly, manage our local 2m FM net and the occasional VHF/UHF contest. Some people enjoy satellites, MS or moonbounce. Others just like to ragchew on 80m.

We must rejoice that there are so many different, yet equally valid, ways of enjoying ourselves. We have a great hobby.

Look at this huge sunspot, the largest yet of Sunspot Cycle 24! It is about the same diameter as Jupiter! Notice how tiny Earth is, in comparison. Sunspots are regions on the Sun’s photosphere, formed by the “convection” of solar plasma deep inside the Sun, causing the twisting and shifting of magnetic fields. They look like spots on the photosphere because they are cooler than their surrounding solar material, giving them their dark, blemish-like appearance.

The sunspot is the largest since November 1990, and is larger than a monster sunspot that spawned a series of major solar flares over Halloween in 2003. AR 2192 was one of the biggest observed sunspots of all time, ranking 33rd largest of 32,908 active regions since 1874, according to NASA scientists C. Alex Young and Dean Pesnell.

Interestingly, this sunspot never released any major coronal mass ejection (CME), because the magnetic fields were too strong to let any significant plasma escape! However, this sunspot group unleashed a fair number of moderate to strong x-ray flares (see one of them in this video at < http://g.nw7us.us/1s7L0vF >). All told, AR 2192 popped off 26 M-class flares, and six X-class flares! Of course, during the last sunspot cycle, Cycle 23, there were many active sunspot regions unleashing flare after flare within hours of each other. That’s typical during the active phase of most sunspot cycles. This cycle, however, is one of the weakest on record, so this large sunspot with its many flares is exciting.

Each sunspot region gets a consecutive number assigned to it by the National Oceanic and Atmospheric Administration (NOAA). This sunspot region is NOAA AR (active region) Nr. 12192 (we often drop the first digit when speaking of a sunspot, so in this case, this region was often referred to as AR 2192).

One of the many x-ray flares originating from Active sunspot Region AR 2192 – this one seen in Extreme Ultraviolet at 131 Angstroms.

This sunspot region increased the ionization of the ionosphere, creating excellent conditions on all of the high frequency spectrum (shortwave, or HF). Even ten meters was alive with world-wide propagation. And, the best news is that this provided an exciting playing field for the CQ WW SSB contest in late October, 2014.

This sunspot region has now rotated away, but may return on about 24 days.

I’m late in getting this update published.  I was on vacation (staycation at home) as June ended and July began.  This past week was my first week back and I was swamped at work.  But all is on track and I’ve completed at least one QSO each and every day in 2014 and the challenge is well over 50% complete. 

In addition, to keeping my QSO per day streak alive…I’ve also managed to add at least one new DX entity each month in 2014.  June was no exception with the addition of Saint Lucia.   This makes 10 new DX entities added to my log this year. 

As I started with my May update, my progress in the 2014 ARRL Centennial QSO Party continues to progress.   The numbers below are as of mid July.

Centennial Points Score:  9,049

Total QSO’s:  1,539

Rank (All): 1,230

Rank (Colorado): 14th

The QSO breakdown for June is as follows:

Mode  Number QSO’s

JT65 20

JT9 32

SSB 538

PSK31 0

MFSK16 0

RTTY 0

2m FM 0

Additional notes of interest:

DX Stations Worked in June – 44

New DX Entities in June – 1

New DX Entities for 2014 – 10

Total QSO’s for June – 590

Total QSO’s for 2014 – 2,234

Total consecutive QSO days – 181

Days left in 2014 – 184

Until next time…

73 de KDØBIK

Just before the 4th of July, several sunspot regions rotated into view. Today, they are significant players in elevating the solar output of Extreme Ultraviolet energy — the energy helpful in ionizing the F-region of our Earth’s ionosphere. That, in turn, means better propagation conditions, even on higher shortwave frequencies.

As seen by the Solar Dynamics Observatory, the Sun is sporting quite a few sunspots, today. These are helping elevate the 10.7-cm flux, which is a proxy for solar output that strengthens the ionospheric propagation of higher frequencies in the shortwave spectrum. Expect good conditions on HF, this weekend.

73 and best DX!

Why would an amateur radio operator be interested in space weather?  Is it worth the time and resources to forecast propagation, in the daily operation of a typical ham radio station?

Gary, host of the popular ‘Ham Radio Now’ video podcast, talks with Tomas Hood (NW7US), propagation and space weather columnist for CQ Amateur Radio Magazine (and in the late ‘Popular Communications Magazine’ as well as ‘CQ VHF Quarterly Magazine’) and The Spectrum Monitor Magazine. Gary discusses with Tomas how scientists forecast space weather, and how the average ham radio operator can also make predictions, and what propagation forecasting can bring to the daily operations of an amateur radio enthusiast.
