Weekly Propagation Summary (2016 Feb 29 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2016 Feb 29 0233 UTC.

Highlights of Solar and Geomagnetic Activity 22 – 28 February 2016

Solar activity reached low levels with only C-class flare activity observed this period. Region 2506 (S05, L=224, class/area=110/Dai o 28 Feb) was responsible for nearly all flare activity this period including three low-level C-class flares, the largest of which was a C3/Sf flare at 0500 UTC on 27 Feb. A filament eruption centered near S16E19 (vicinity of Region 2506) was observed in SDO/AIA imagery between 0030-0130 UTC on 18 Feb but no associated coronal mass ejection (CME) was observed in LASCO coronagraph imagery suggesting the bulk of the plasma was reabsorbed. No Earth-directed CMEs were observed this period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 22-24 and 28 Feb with moderate levels observed throughout the remainder of the period.

Geomagnetic field activity briefly reached unsettled levels on 23-24 and 26 Feb with quiet conditions observed throughout the remainder of the period under a nominal solar wind regime.

Forecast of Solar and Geomagnetic Activity 29 February – 26 March 2016

Solar activity is expected to be very low with a chance for C-class flares on 29 Feb and 15-26 Mar. Solar activity is expected to increase to low levels with a chance for M-class flares (R1-R2 (Minor-Moderate) Radio Blackouts) on 01-14 Mar due to the return of old Region 2497 (N12, L=240) which produced four M-class flares last rotation.

No proton events are expected at geosynchronous orbit barring any significant flare activity.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 15-22 Mar, moderate levels on 04-05, 07-08, 13-14, and 23-26 Mar, and at normal levels for the remainder of the period.

Geomagnetic field activity is expected to reach G1 (Minor) geomagnetic storm levels on 14-16 Mar and active levels on 01, 06, and 17 Mar due to the effects of multiple recurrent coronal hole high speed streams (CH HSSs). Quiet or quiet to unsettled geomagnetic field conditions under a nominal solar wind regime are expected for the remainder of the period.

V29RW: Slacker DXpedition to Antigua

Recently, I had another opportunity to take ham radio along on vacation to a Caribbean island, this time to Antigua. This was not a super-gonzo turbo-charged DXpedition. I just worked in some radio action in between snorkeling and beach walking. This is referred to as a “holiday style” DXpedition, or maybe it’s just the slacker approach.

Radio Equipment

The radio gear needed to fit easily into my luggage. After all, we’ve got snorkel gear to take along. I wanted to put out a healthy signal from the island, so I rejected the idea of running QRP, opting instead for a 100W transmitter. Ultimately, I chose to take a Yaesu FT-991 which is full-power and full-featured but still relatively compact. It easily fit into my carry-on bag along with some other items. Having a built-in antenna tuner was a real plus and it was also good to have the 2m and 70 cm bands.

Choosing an antenna was a critical item. My first thought was to take my Buddistick antenna which covers the HF bands I was interested in working: 20m, 17m, 15m and 10m. I used that antenna from the Virgin Islands and it was really handy for taking to the beach. This time I wanted something bigger under the theory that size does matter. On the other hand, I wasn’t going to take full size yagis for each of the bands. I finally settled in on using End-Fed Half Wave (EFHW) antennas for the 4 bands (from LNR Precision). This gave me a simple half-wave antenna on each band with no coils, no traps, nothing funny going on. These antennas radiate well and have decent bandwidth…any SWR degradation can be tweaked up quickly using the FT-991 antenna tuner.

Steve WGØAT suggested I use the SOTABEAMS 30-foot mast to support the EFHW antennas. It is an incredible mast that collapses to 26.5 inches, small enough to fit into my bag. This antenna set up is common with the SOTA activators: EFHW supported by some kind of lightweight pole. I also tossed in a 19-inch magmount antenna for 2m and 70cm. (I did find a good repeater on on 147.0 MHz but did not spend much time on it.)

Rounding out the kit was an Astron switching power supply, a 25-foot length of RG-8X coaxial cable, a Heil Traveler headset and a few patch cords. I found it tempting to keep throwing more stuff in the bag so I adopted the backpacker mentality of taking just what I needed and not much more. For computer logging, I chose N1MM Plus software, set to log type to “DX”.

I have to confess that I did manage to break the 30-foot mast early in the trip. The house was on a hill and we always had a strong breeze coming through. One day it flexed the mast enough to break it. This was quickly repaired with duct tape. After that, I did not use the 2 top sections of the mast which reduced the amount of sway in the wind (and stress on the mast).

My operating time was a bit sporadic and my operating strategy was simple: work the highest band (of 20m, 17m, 15m and 10m) that had some decent propagation to somewhere. Antigua is not extremely rare but it seemed to attract attention. Typically, I called CQ, worked a few stations and then a big pileup would develop. I made lots of QSOs with stations in North America, South America and Europe. I also made a few contacts into Africa but none with Asia. Signal reports were generally good (S9 +), so the antennas were doing the job.

All in all, I was pleased with the contacts I made, given the slacker effort. I especially enjoyed working 17m, a band I have not spent that much time on. The propagation is similar to 20m but noticeably less jammed with signals.

  Band  QSOs DXCC
    14   309   36
    18   162   13
    21    21   10
    28    91    6
 Total   583   65

QSLs for V29RW should be sent to my home callsign: KØNR (direct or via the bureau). Logbook of the World contacts have already been confirmed. Instant gratification, baby!

Licensing info: It was relatively easy to get a ham radio license in Antigua, based on my US license (fees were $30 US). See this web page.

Heathkit Pipetenna

heathkit-pipetennaThe resurrected Heathkit company has launched a dual band antenna.  As much as I want them to succeed is this the best they can do?

They absolutely have to produce decent kits at decent prices or they will not survive. Their offerings so far do not exactly set the world alight. No, the offerings so far have not excited me. Years ago I started out with a Heathkit  Electronics Workshop. Years later I had an HW8 which gave me loads of contacts with small wire antennas.

Please, think of your potential customer base, think about prices, and look at your competitors. I have no doubt a few loyal USA customers will support you, but far far more is needed in the competitive world of the 21st century.

The FCC says you have a new callsign. Now what?

Once I knew that I had a new callsign, I sat down a wrote down a list of what I needed to do…

(1) QRZ.com website. When my callsign changed a few years back from AD7MI to NI0L, I jumped on the air to “test it out”. On 20m, I was having a PSK31 QSO when the distant party thought I was a pirate station because on QRZ.com my new callsign did not reflect the name and QTH I was using. A pirate! I explained that it was a new callsign but I could tell that the other guy was not buying it.

I thought I would need to go on to QRZ.com and register as a new user. I made a posting in the QRZ.com forum category dedicated to callsign problems. The end result: just wait… the change will take place automatically in a few days.

And that is the case. If you are a US ham and change your callsign, just wait. Within two or three days the callsign change will be reflected on QRZ.com. If you get on the air before QRZ.com is updated, be prepared for people to think you are a pirate.

(2) Log of The World. Easy to do. Just submit for a new certificate under the new callsign. ARRL usually responds within one working day.

(3) EchoIRLP node. This ended up being much easier than I thought it would be.

a. To change your callsign in the IRLP database, go to this webpage using a computer connected to the same router as the IRLP node.

b. Go into your node and edit irlp/custom/environment file to change the old callsign to the new callsign. Restart the node and verify the changes have taken effect.

c. For the EchoLink side:
Validate your new callsign.
– Check for validation of the new EchoLink call sign / node number on EchoLink using the EchoLink PC client software. Remember, EchoIRLP only allows link (-L) or repeater (-R) nodes.
– Note: you can only register the new callsign once the EchoLink folks of pulled the latest and greatest database update from the FCC. This may take a day or two. Once that is done, you can validate your new callsign. Your new callsign will be assigned a new EchoLink node number. If you want to use your previous node number, EchoLink allows you to swap node numbers between your old callsign and your new callsign.

– Once you are validated and have swapped node numbers edit the files and settings listed below:

/home/EchoIRLP/ custom/tbd. conf
ConferenceCall =
ConferencePass =

/home/EchoIRLP/ custom/echo_ environment
export ECHO_MYCALL=

/home/EchoIRLP/ custom/userdata. txt

Restart IRLP from root login with script /home/irlp/custom/ rc.irlp, or reboot the node.

IRLP node 4433 and EchoLink node 536398 are up and operational.

(4) APRS – change the callsign in my vehicle, HTs, and UI-View32. Pretty straight forward. The home weather station info can now be found here.

(5) Change the blog website. I have been keeping an amateur radio blog for about 10 years now. Web hosting companies make it pretty easy to get a domain for your website and then setup web hosting. I like using WordPress to setup and maintain the actual blog. Fairly straight forward but flexible to do just about anything you would want for a amateur radio blog. The new website is up and running.

(6) Callsign license plate. Kansas makes the pretty simple. I went down to my county office on Friday after work. The application process was smooth and the wait should be about 4-6 weeks.

(7) New QSL card. I am thinking of going with this:

NI0L…. Happy Trails!

I have a new, bright, and shiny callsign!

When I made the decision back in 2013 to stay in Kansas after retiring from the military, I decided I would try to get a callsign for zero-land (or ten-land, if you like). It was time to leave my 7-land callsign and fully embrace being a citizen of the sunflower state. NI0L was available and I applied for it without much thought. After having the callsign for a while, I noticed many hams were confused with the 2×1 call. The most common mistake was flip flopping the zero and the “i”. Another common mistake was interpreting the “i” as one and then the zero would become an “o” (N1OL). All very confusing.

The hunt for a new callsign was on. I determined that a new callsign would still be from zero-land, thus greatly reducing the pool of available calls. In an effort to avoid callsign confusion, I further resolved that the call would be a 1×2 call. The good news was that the vanity callsign fee was no more. The bad news was that everybody and their brother was applying for vanity calls. For the last few months I kept at it – watching which calls became available and then submitting applications. Waiting. The odds where never in my favor. Often there would be 10 or twelve applying, all in competition.

Perseverance finally paid off. Last week the FCC said that I was now the proud holder of N0ZB. It is a 1×2 call, that should alleviate some confusion. The “zero” and the “zulu” may prove to be a bit of a tongue twister, but I think it will be far less of an issue and having the “zero” and an “i” next to one another.
