ARRL Audio News - November 15, 2019

Even with little to no solar activity, it is amazing how many long-distance HF contacts are possible, even without using weak signal modes such as FT8.

Recent DXpeditions, such as the ones on Pitcairn Island and Marquesas, had little trouble piling up the contacts, even on ten meters. It helps that we are in the fall season.

No sunspots over the past week, and average daily solar flux was about the same as last week’s report, 70.3 compared to 70.4. Geomagnetic indices were still quiet, with average daily planetary A index at 4 (last week was 4.1) and middle latitude A index at 3 (compared to 2.7).

Predicted solar flux is 71 on November 15 to December 3, 70 on December 4-18, and 71 on December 19-29.

Predicted planetary A index is 5, 12 and 8 on November 15-17, 5 on November 18-19, then 18, 25, 18, 12 and 10 on November 20-24, 8 on November 25-26, 5 on November 27 through December 16, then 15, 25, 18, 12 and 10 on December 17-21, 8 on December 22-23, and 5 on December 24-29.

This forecast is the same as the one appearing on Thursday in the ARRL Letter. Check daily updates at ftp://ftp.swpc.noaa.gov/pub/forecasts/45DF/. These are updated daily after 2100 UTC, most recently between 2110-2151 UTC.

Geomagnetic activity forecast for the period November 15-December 10, 2019 from OK1HH.

Geomagnetic field will be
Quiet on: November 18-19, 29-30, December 1
Quiet to unsettled on: November 15, 27-28, December 4-10
Quiet to active on: November 16 (-17, 25-26), December 2-3
Unsettled to active on: November 20, 24
Active to disturbed: November 21-23

Solar wind will intensify on: November 21-26, (27-29)

Parenthesis means lower probability of activity enhancement.

Bil Paul, KD6JUI, is still operating regularly from his kayak in Northern California. QST published an article about his boat and antenna in the November 2016 issue. “I was again operating from a kayak (November 9, Saturday), this time from Lake Berryessa in northern California. The first contact I had (17-meter CW at noon Pacific time) was with “Moz” VK3CWB in Australia. I was, as before, running 10 W into a 34-foot end-fed half-wave wire vertical set up in a fallen-over tree at the edge of the lake. Although at first, he had trouble copying my call sign, he did give me a 539 report.

“What amazed me was that directly behind me was a hill that I thought would cut my signal in his direction. Perhaps my signal was bouncing off the hills on the other side of the lake.

“One of my reasons for writing in is to show that QRP signals even in this time of low solar activity can get through overseas, especially if one is operating from a watery location.

“I go out in the kayak around once a week and operate. The antenna is loadable on 17, 20 and 30 meters. There was plenty of activity on all those bands yesterday, but I only had contacts on 17 and 30. My buddy caught his first trout on his end of things. A good day all around.

“I get a very good QSL-card return from foreign stations when I send them my kayak QSL card.”

KA3JAW reported an 11-meter sporadic-E opening on the evening of November 13. Local sunset was 4:44 PM and the opening began 2 hours and 31 minutes later and ended 4 hours and 16 minutes after sunset. He is in Easton, Pennsylvania and heard transmissions from Alabama, Georgia, Kentucky, North Carolina, South Carolina, and Virginia.

Emergency Net on 7.110 MHz

“A tsunami alert has been issued after a 7.4 magnitude earthquake struck off the northwest of Indonesia‘s Maluku Islands.

The tremor was measured 83 miles (134km) from the port city of Ternate at a depth of 30 miles (45km), according to the US Geological Survey.

Indonesia’s Meteorology and Geophysics Agency issued a tsunami alert following the quake, which hit roughly equidistant from the islands of Sulawesi and Halmahera.

Stephen Hicks, a seismologist at Imperial College London, said: “Fortunately, it has occurred offshore and at a reasonably deep depth so risk of damage from shaking and tsunami is low.””

The Marquesas TX7T DXpedition, sponsored by the Can-Am DXpedition Group, moved on to Hiva Oa on November 6. Operation is scheduled to continue until November 17, with the team heading home a couple of days later. Typically, three or four stations are on the air on CW, SSB, and FT8 on all of the 160 – 10 meter bands.

Europe is a key target area, and “every attempt will be made to take advantage of propagation,” the DXpedition has indicated. The DXpedition is mostly funded by the operators themselves, but contributions are welcome and will go toward freight and shipping costs.

The Marquesas Islands rank #59 on the Club Log DXCC Most Wanted list. The TX7T logs are available on OQRS.

The post Still Time to Work TX7T in the Marquesas Islands appeared first on QRZ NOW - Ham Radio News.

Description

 A 5 element  Long Boom (2.1m) LFA-Q (Super-rigid Quad-style) Super-Light Quad Style Yagi for 144 – 145MHz

The LFA-Q Packs a bigger punch than a traditional Yagi with MUCH MORE GAIN per metre of boom 

If it is GAIN you want from a small boom, this is the antenna for you!  Wow, Super compact boom!! Massive 12.2dBi from this antenna!

Another impressive design from G0KSC, ‘The Quad has been InnovAted!’ A Quad-style antenna with full wave length loop elements which provide a number of benefits. First, if the elements are of reasonable thickness (as ours are, they are not wire!) then good bandwidth coverage can be achieved. Next, up to around 7 elements (1.5wl) much better gain per metre of boom can be achieved than would otherwise be possible from a traditional Yagi covering the same bandwidth. Finally, with the dual-boom structure and 1/2” diameter elements, the LFA-Q is extremely rigid and can stand up to some serious weather conditions!

IDEAL PORTABLE OR SOTA USE!

Despite it’s rigidity, the LFA-Q is extremely lightweight and this means even in strong winds, snow and ice the LFA-Q will hold its own.

Our antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production to ensure they are within 0.2mm of what they should be, ensuring they work as well as our software model predicts.

• Marine grade Stainless Steel Fittings
• Original Stauff Insulation clamps
• Mill finished boom and elements for highest levels of accuracy

Mount Athos activity

Monk Iakovos, SV2RSG, has been active as SV2RSG/A from the Holy Monastery of Koutloumousiou of Mount Athos. Activity has been on mostly 20 meters at various times between 1100-1830z (some 40m). 
It is interesting that he is now signing with a “/A” (“/A” as meaning of alternative).

Back in July, OPDX was informed that per the DXCC Desk staff, they do not yet have any documentation from Monk Iakovos, SV2RSG, that states he is in fact active from Mount Athos. However, several sources are reporting that Bart Jahnke, W9JJ, ARRL Radiosport and Field Services Manager, has recently stated “operations by SV2RSG/A (if from Mount Athos must identify ‘/A’) are accepted by ARRL DXCC.”

It was verified on Friday, November 8th, (thanks to Goose, W8AV, a Great Lakes DXCC Checker) from the DXCC Desk that SV2RSG/A is good for DXCC.

QSL via SV2RSG/A direct (see QRZ.com).
