 ARRL President Rick Roderick, K5UR, is using the occasion of National Volunteer Week, April 7 – 13, to highlight Amateur Radio’s role in helping the public as volunteers.
“It is the reason many new hams enter the hobby today — to support their communities and our served agencies during emergencies, disasters, and community events,” he said. “I want to thank the thousands of Amateur Radio operators who continue to provide this valuable service. It shows the great value Amateur Radio plays in providing an army of communicators in times of need. I’m proud to be associated with such a fine group of volunteers who commit their time and effort to help others.”
National Volunteer Week is sponsored by Points of Light, an ARRL partner through National Voluntary Organizations Active in Disaster (VOAD). Points of Light called the week-long observance “an opportunity to celebrate the impact of volunteer service and the power of volunteers to tackle society’s greatest challenges, to build stronger communities, and be a force that transforms the world.”

HERCULES 1500 – HF RF POWER AMPLIFIER (1.8 – 30 MHz )
Extremely robust HF RF POWER amplifier, the RF section is equipped with 2 DUAL 1250 Watt (2500W) freescale MOSFETs reduced to 1500 Watt, this in addition to ensuring a high reliability and continuity in the output power, ensures a low IMD. It’s possible to equip it with 1800 W Mosfet while maintaining the rated power of 1500 Watt, this certainly improves the protection on the “standing waves” and of course the already excellent “IMD”
The power section consists of two switcing professional power supplies of 1800 Watt each (3600 W) EATON APR48G, this solution allows to “work” in conditions of absolute “rest” to the apparatus.
A filter guarantees possible disturbances to the power supply network.
The RF section is completely enclosed in a 2 mm thick “BOX”, this BOX is made with “numerical control” machines, therefore extremely precise and robust.
The filter bench required a year of experimentation and testing to guarantee a low harmonic product and a low superheat, thus allowing the HERCULES 1500 to operate “H24” without any problem of “power drift”.
GENERAL DATA
OPERATING RANGES: 160 – 80 – 40 – 30 – 20 – 17 – 15 – 12 – 10 mt.
OUTPUT POWER: 1500 WATT CONTINUES CW KEY DOWN
SWR ACCEPTED: 1-2.5
POWER SUPPLY: 190 – 260 Vac

Solar experts predict the Sun’s activity in Solar Cycle 25 to be below average, similar to Solar Cycle 24
Scientists charged with predicting the Sun’s activity for the next 11-year solar cycle say that it’s likely to be weak, much like the current one. The current solar cycle, Cycle 24, is declining and predicted to reach solar minimum – the period when the Sun is least active – late in 2019 or 2020.
Solar Cycle 25 Prediction Panel experts said Solar Cycle 25 may have a slow start, but is anticipated to peak with solar maximum occurring between 2023 and 2026, and a sunspot range of 95 to 130. This is well below the average number of sunspots, which typically ranges from 140 to 220 sunspots per solar cycle. The panel has high confidence that the coming cycle should break the trend of weakening solar activity seen over the past four cycles.
“We expect Solar Cycle 25 will be very similar to Cycle 24: another fairly weak cycle, preceded by a long, deep minimum,” said panel co-chair Lisa Upton, Ph.D., solar physicist with Space Systems Research Corp. “The expectation that Cycle 25 will be comparable in size to Cycle 24 means that the steady decline in solar cycle amplitude, seen from cycles 21-24, has come to an end and that there is no indication that we are currently approaching a Maunder-type minimum in solar activity.”
The solar cycle prediction gives a rough idea of the frequency of space weather storms of all types, from radio blackouts to geomagnetic storms and solar radiation storms. It is used by many industries to gauge the potential impact of space weather in the coming years. Space weather can affect power grids, critical military, airline, and shipping communications, satellites and Global Positioning System (GPS) signals, and can even threaten astronauts by exposure to harmful radiation doses……READ MORE

Many thanks to the Southgate ARC who notes this recently published 1947 silent film from the Radio Society of Great Britain:
The RSGB has released a vintage silent black and white video of an Amateur Radio Direction Finding (ARDF) field day held in 1947 at Chipping Barnet which was then in Hertfordshire
The Incorporated Radio Society of Great Britain titled the video – D/F Field Day (North of the Thames) May 18th 1947. It has been added to the many amateur radio videos that can be viewed on the Society’s YouTube channel.
One thing that’s apparent from the video is the difference in the age range of those who participated in amateur radio in the late 1940’s compared to today.
Watch RSGB Archive film – D/F Field Day 1947
Click here to view on YouTube.
Pages 69-70 of the RSGB Bulletin (forerunner of RadCom) for October 1947 contained a fully illustrated report on the North of the Thames ARDF event as well as the South of the Thames event held on July 6, 1947.
The two leading affiliated societies on May 18 were from Essex:
1st Romford and District Radio Society
2nd Southend and District Radio Society
The two clubs swapped positions for the July 6 event.
Fascinating! I love how everyone wore proper attire and much of the equipment was home brew. I imagine operators were happy to go back to field and enjoy all sorts of radio activity so close on the heels of WWII.

The rules have been posted for QRP To The Field for 2019. I seriously doubt that i will be able to participate this year as the scheduled date is Saturday, April 20th - which is also Holy Saturday of Easter Weekend.
At any rate - here are the rules (as per NA5N) for those who are not otherwise occupied:
Gang,
It’s now spring (though hard to believe in some parts of the country) and April is almost here. Time for QRP TO THE FIELD.
The 2019 QRPTTF Rules are here: http://www.zianet.com/qrp/qrpttf/2019/ttf.htm
I’ve received several emails regarding this years QRPTTF, like:
1) My favorite forest and campground burned down and now closed
2) Go for a water theme as my town is still under water
3) The bridge leaving town to my favorite spot is still closed
4) Can’t travel too far these days - pick something close
So on the side of caution, this year’s QRPTTF is laying low and pretty easy … “Any Ole Park” from the empty lot down the street to a recognized park. Can be close to home for safety for those in flood areas and closed highways. And of course, SOTA operations are invited as always.
Last year’s QRPTTF the solar flux was rock bottom at 64. The USAF is predicting a solar flux of 74-78 and Kp=2 for April 20, so at least some improvement to daytime HF. Maybe we’ll get a little solar flare to kick it up even higher (actually been a few solar flares past couple of weeks).
So get your field gear out of winter hibernation and give it a checkout for April 20.
73, Paul NA5N
So there you have it, for your edification.

As it slowly turns to Spring and warmer weather in NJ, it has become relatively comfortable once again, in the W2LJ basement shack. I can go down there for extended periods of time without freezing, as the ambient temps have returned to the 60s.
Last night, 40 Meters was positively jumping! And it turned out to he a rich Fox hunting environment. I was able to work both Jim N0UR and Wayne N4FP within the first 15 minutes of the hunt. The Propagation Princess smiled on me last night, and THAT hasn’t happened in a very long time. It felt good. There were so many missed pelts this past Winter season that I was beginning to doubt my equipment, my antennas and my skills - each at one time or another.
Rather than run upstairs, I put some more time into my DSO138 Oscilloscope kit. I started it on Sunday and I’ve been doing a little bit every day. So far, I’ve gotten all the resistors, diodes, switches and RF chokes in. If I get home early enough from tonight’s South Plainfield Amateur Radio Club meeting, I’ll get the capacitors in.
After that, there’s not much more to it. I should be able to complete it by the end of the weekend, if all goes well. After that, I think either my 4 States Ozark Patrol receiver, or my 40 Meter QCX kit will be next.
Oh, and by the way, that Mustel G600 microscope came in mighty handy last night. One of the components soldered into the DSO138 circuit board last night was a mini USB connector jack. The pins on that thing are entirely way too tiny and close together. I thought that there was no way I was going to be able to get that thing soldered in without creating one or more solder bridges. After I finished making the last solder joint, I brought out the Mustel and gave the solder pads a good look at ultra high magnification. No bridges!
You may be thinking that the kit building season is traditionally Winter. Not for me. I try to limit my time down in the basement when it’s uber cold. Not only is it uncomfortable; but it’s bad for the arthritis I have in my hands and my ankles. When I want to operate in the Winter, I either turn on a space heater down there; or I resort to operating from the living room using my magloop. And that’s not a bad alternative, actually. It’s definitely not as nice as using my outdoor antennas. However, if someday Marianne and I decide to sell the house when we retire, and we end up in some place that doesn’t allow outside antennas - the magloop will provide a suitable, stealthy solution. It would not be the death knell of Amateur Radio for me.

 ” The next big event will be the ARISS SSTV event that starts Thursday, April 11 about 18:00 UTC and will be operational until about 18:00 UTC on Sunday, April 14. Since this event will run continuously for 72 hours, folks in the higher latitudes should have a pretty good chance to receive all 12 of the images.

Many thanks to the Southgate ARC who notes this recently published 1947 silent film from the Radio Society of Great Britain:
The RSGB has released a vintage silent black and white video of an Amateur Radio Direction Finding (ARDF) field day held in 1947 at Chipping Barnet which was then in Hertfordshire
The Incorporated Radio Society of Great Britain titled the video – D/F Field Day (North of the Thames) May 18th 1947. It has been added to the many amateur radio videos that can be viewed on the Society’s YouTube channel.
One thing that’s apparent from the video is the difference in the age range of those who participated in amateur radio in the late 1940’s compared to today.
Watch RSGB Archive film – D/F Field Day 1947
Click here to view on YouTube.
Pages 69-70 of the RSGB Bulletin (forerunner of RadCom) for October 1947 contained a fully illustrated report on the North of the Thames ARDF event as well as the South of the Thames event held on July 6, 1947.
The two leading affiliated societies on May 18 were from Essex:
1st Romford and District Radio Society
2nd Southend and District Radio Society
The two clubs swapped positions for the July 6 event.
Fascinating! I love how everyone wore proper attire and much of the equipment was home brew. I imagine operators were happy to go back to field and enjoy all sorts of radio activity so close on the heels of WWII.
