Blogging……has it seen it’s time?

This past weekend up here in Canada has been a long weekend with the Monday as  a holiday. I spent some time just Googling " ham radio blogs" "Amateur radio blogs". I had many hits and  upon visiting the pages that were listed I found most were no longer being updated. I came across blogs were the last post was a few years old. I came across more blogs that have been abandoned than ones that are up to date. I will admit my blog is not updated as often as it should do to the fact there are many things going on and unfortunately the blog sometimes takes second or third seat. With the Google search that I did and the results that came back it begs the question "is blogging becoming something of the past?"  I very much enjoy reading the blogs I have listed on my blog as favourites. I also go to other blogs and check out who they follow and read those as well. I am very much enjoying my blog reading but I was shocked to see how many blogs out there are no longer current. So my question of the day is......"is blogging on it's way out?"

Hunting For NDBs In CLE244



This coming weekend will see another monthly CLE challenge. This time the hunting grounds will be split:    260.0 - 269.9 kHz and 440-1740kHz.

 

For those unfamiliar with this monthly activity, a 'CLE' is a 'Co-ordinated Listening Event', as NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.

If you've been meaning to participate in  CLE, then maybe this weekend is a fine time to try! Lately, we've had a lot of first time submissions so you won't be alone!

As well, if you're trying to learn CW, copying NDBs is perfect practice as the identifier speed is generally slow and the letters are repeated again every few seconds!

A nice challenge in this one is to hear VR - 266 kHz. 'VR' is the outer marker for the '26s' at Vancouver International (CYVR) and is located in Richmond, BC.

'VR' runs 50W into a closed triangular loop but is well-heard throughout North America having been reported as far as North Carolina to the east and Hawaii to the west.. Listen for its upper-sideband CW identifier (with your receiver in the CW mode) on 266.404 kHz.

At this time of the season, summer lightning storms may provide additional listening challenges but maybe we will get lucky. Propagation can often be as good as mid-winter if the lightning cooperates.

When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. Listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are modulated with a 1020 Hz tone approximately.

For example, 'AA' near Fargo, ND, transmits on 365 kHz and its upper sideband CW identifier is tuned at 366.025 kHz while its lower sideband CW ident can be tuned at 363.946 kHz. Its USB tone is actually 1025 Hz while its LSB tone is 1054 Hz.

Often, one sideband will be much stronger than the other so if you don't hear the first one, try listening on the other sideband.

Canadian NDBs normally have an USB tone only, usually very close to 400 Hz. They also have a long dash (keydown) following the CW identifier.

All NDBs heard in North America will be listed in the RNA database (updated daily) while those heard in Europe may be found in the REU database. Beacons heard outside of these regions will be found in the RWW database.

From CLE organizer Brian Keyte, G3SIA, comes the details:


Hello all,

Our end-of-May Coordinated Listening Event will soon be here.
It will be a hunt for normal NDBs in two contrasting frequency ranges.
As always, first-time CLE logs will be extra welcome.

    Days:    Friday 24 May - Monday 27 May
    Times:   Start and end at midday, your local time
    Targets: Normal NDBs  (not NAVTEX or *amateur beacons)
    QRG:     260.0 -   269.9 kHz
     plus:     440.0 -  1740.0 kHz

These are interesting frequencies for most of us, with some quiet
wide-open spaces.  We last used them for CLE228 in January 2018.

Most of us should be able to hear some NDBs in both ranges, though
Europe only has a handful in the '260s'.  From 440 kHz onwards, North
America has a few, mostly around 510-530 kHz, but listeners in Eastern
Europe have a BONANZA – probably over 400 active NDBs in Russia
(RUS + RSE) alone, though for most of us in Western Europe many of
them are hiding among Europe's Medium Wave Broadcast Stations.

*(There used to be amateur beacons using CW on frequencies mainly
around 474 - 478 kHz.  Over the years they have been moving to use
other frequencies and modes. Last time we only heard three and only
in Europe.  So we’ll no longer be listening for Amateur signals in this
CLE's frequency range)

Please send your CLE log to NDB List, if possible as a plain text email
and not in an attachment, with 'CLE244 FINAL' at the start of its title.

Show on EVERY line of your log:
  #   The Date  e.g. '2019-05-25', etc.  (or just '26')
  #   UTC  (the day changes at 00:00 UTC).
  #   kHz  - the beacon's nominal published frequency if you know it.
  #   The Call Ident.

Those main items can be in any order within themselves, but BEFORE any
other optional details (Location, Distance, etc.) later in the same line.

As always, give details in your log of your own location and the receiver,
aerial(s), etc. that you were using.
If you send any interim logs, be sure to send a FINAL (complete) one.

You can find anything else to help you, including CLE seeklists for your
part of the World, from the CLE page, http://www.ndblist.info/cle.htm

Please look out for extra information in the Final Details in a few days
with advice about log-making, etc.

(Reminder:  You could use any one remote receiver for your loggings,
stating its location and owner - with their permission if required.
A remote listener may NOT also use another receiver, whether local
or remote, to obtain further loggings for the same CLE).

These listening events serve several purposes. They:
  • determine, worldwide, which beacons are actually in service and on-the-air so the online database can be kept up-to-date
  • determine, worldwide, which beacons are out-of-service or have gone silent since the last CLE covering this range
  • will indicate the state of propagation conditions at the various participant locations
  • will give you an indication of how well your LF/MF receiving system is working
  • give participants a fun yet challenging activity to keep their listening skills honed

The NDB List Group is a great place to learn more about the 'Art of NDB DXing' or to meet other listeners in your region. There is a lot of good information available there and new members are always very welcome. As well, you can follow the results of other CLE participants from night to night as propagation is always an active topic of discussion.

You need not be an NDB List member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers. 

Remember - 'First-time' logs are always VERY welcome!

Reports may be sent to the NDB List Group or e-mailed to CLE co-ordinator, Brian Keyte (G3SIA), whose address appears above. If you are a member of the group, all final results will also be e-mailed and posted there.

Please ... give the CLE a try ... then let us know what NDB's can be heard from your location! Your report can then be added to the worldwide database to help keep it up-to-date.

Have fun and good hunting!

Weekly Propagation Summary – 2019 May 20 16:10 UTC

Weekly Propagation Summary (2019 May 20 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2019 May 20 0537 UTC.

Highlights of Solar and Geomagnetic Activity 13 – 19 May 2019

Solar activity was at very low to low levels, with low-level activity observed on 15 May due to a C2.0/SN flare from Region 2741 (N05 L=272, class/area Hsx/160 on 15 May). Very low-level activity was observed for the remainder of the period. Two eruptions were observed in coronagraph imagery, but were directed east and determined to not be geoeffective.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 13, 15, and 16 May. Normal to moderate levels were observed for the remaining days in the period.

Geomagnetic field activity reached G3 (Major) storm levels on 14 May due to effects from a CME that erupted on 11 May. G3 storm conditions were observed during the 14/0600-0900 UTC synoptic period, with G2 stom conditions occurring in the 14/0300-0600 UTC period. Active conditions occurred in the 14/0900-1200 and 14/1800-2100 UTC periods. Solar wind parameters at the DSCOVR spacecraft were enhanced with Bt reaching as high as 15 nT accompanied by prolonged periods of southward Bz. Solar wind speed reached a maximum of 568 km/s. Unsettled conditions were observed on 16-17 May. Quiet conditions were observed for the remainder of the summary period.

Forecast of Solar and Geomagnetic Activity 20 May – 15 June 2019

Solar activity is expected to be very low levels throughout the period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at high levels on 21-24 May and 29 May – 02 June due to coronal hole high speed stream effects. Normal to moderate levels are expected for the remainder of the period.

Geomagnetic field activity is expected to be at active levels on 29 May due to recurrent coronal hole activity. Quiet to unsettled levels are expected for the remainder of the period.

Go Ahead and Use Phonetics on 2m FM

Sometimes radio amateurs suggest that phonetics are not needed on VHF FM.  (See examples here and here.) Sometimes it even sounds like it’s a bad thing to use phonetics on FM.  It is inefficient and slows things down. I can see the logic behind this because with decent signal strength, demodulated FM audio is usually quite clear and easy to understand.

Here’s what I wrote in my VHF FM Operating Guide, also downplaying the need for phonetics:

The use of phonetics is not usually required due to the clear audio normally associated with frequency modulation. Still, sometimes it is difficult to tell the difference between similar sounding letters such as “P” and “B”. Under such conditions, use the standard ITU phonetics to maintain clarity. Many nets specifically request the use of standard phonetics to make it easier on the net control station.

The FCC Technician exam gives the topic of phonetics a light touch with just these two questions:

T1A03 (D)
What are the FCC rules regarding the use of a phonetic alphabet for station identification in the Amateur Radio Service?

A. It is required when transmitting emergency messages
B. It is prohibited
C. It is required when in contact with foreign stations
D. It is encouraged

And this one:

T2C03 (C)
What should be done when using voice modes to ensure that voice messages containing unusual words are received correctly?

A. Send the words by voice and Morse code
B. Speak very loudly into the microphone
C. Spell the words using a standard phonetic alphabet
D. All of these choices are correct

Use Phonetics

In practical radio operating, there are a number of things that can degrade communication, usually by creating noise sources that compete with the voice modulation. Most of these are a factor even if the RF signal is strong:

  • A noisy environment at the receiving end (e.g., background noise such as road noise in an automobile)
  • A noisy environment at the transmitter (e.g., background noise such as wind noise outdoors)
  • Poor frequency response of the overall system (e.g., high frequencies may be lost in the transmitter, receiver or repeater, making it more difficult to understand the voice communication).
  • Hearing impairment of the person receiving the audio (I’ve heard that we are all getting older)
  • Difficulty understanding the person speaking (poor enunciation, unfamiliar dialect or accent, etc.)

So I say go ahead and use phonetics on VHF FM, especially for critical information such as your call sign. FM communication is not always clear and easy to understand. It suffers from the same signal-to-noise problems as other voice modes. (Perhaps not as bad as SSB on HF, but it’s still a factor.) In most cases, you’ll want to stick with the standard ITU phonetic alphabet (also known as the NATO alphabet).

Many nets request that you use ITU phonetics when you check in. Imagine being the Net Control Station for a net and having everyone making up their own phonetics. You would have call signs coming at you with all kinds of random words associated with them.  It is much better to have consistency. However, there are times when you might want to use alternative phonetics. See the HamRadioSchool.com article: Phonetic Alphabets for more insight on that.
