A Tale of Two Radios: CommRadio CTX-10 vs. Elecraft KX2
By Thomas Witherspoon K4SWL

A longtime ham and shortwave listener who enjoys taking his hobby into the field, Thomas was intrigued by two seemingly different transceivers that also appeared to have a lot in common. Which would be better for his purposes and why? Both offer low-power and battery-operated portability, but with a totally different design approach. Thomas examines the pros and cons of the CommRadio CTX-10 and the Elecraft KX2, not the least of which in the monetary component.

TSM Reviews: SDRplay RSPdx Software Defined Radio
By Larry Van Horn N5FPW

SDRplay Limited is a UK-based company that has been developing cutting-edge software defined radios since 2014 with its RSP1 model. In the ensuing years, newer models have offered advanced reception features on receivers capable of tuning from 1 kHz to 2 GHz at moderate price levels. In this review Larry takes a look at the company’s latest product, the SDRplay RSPdx and compares it with lower level SDRplay editions.

Radio in the Pre-Broadcast Era Series:
The Trailblazers of Commercial Radio Manufacturing in the 1920s
By Richard Fisher KI6SN

Beneath the dust accumulated over 100 years of consumer-entertainment radio broadcasting are the names of literally hundreds of manufacturers who have largely disappeared since the AM band gold rush of 1920. Richard takes a look at the radios available 100 years ago and finds a long list of names that urgently filled a huge void in practical receivers that could capture the signals of the handful of commercial broadcast stations that burst onto the airwaves early in the second decade of the 20th Century.

A nice surprise on 60m FT8

I was on 60m operating FT8 just after finishing dinner and to my surprise a fellow blogger John AE5X was calling me on the waterfall. A very nice surprise for sure I have read his blog for some time and it was great to make contact with him on the rig.

If you don’t like the weather in NJ

just wait five minutes, as the "borrowed" old saying goes! I guess that holds for long range forecasts, too.

I've been keeping an eye on the long range weather forecast via WeatherUnderground for this coming Saturday - FYBO day.

A couple of days ago, they were calling for a wet weekend. This morning, they were calling for an ice storm in the morning with some showers in the afternoon after a warm up.

NOW it's supposed to be "just" a cloudy day with just a chance of showers. Meanwhile, last night on the news, the local weather prognosticator was calling for a possible Nor'Easter this weekend. It's enough to make your head spin!



I was hoping to go up to Washington Rock State Park for a couple of hours. That's my favorite place to operate portable from - plenty pf picnic benches and a plethora of tall trees. But with this ambiguous and ever changing forecast, I got the bright idea to go to Putnam Park in town, instead. That's where SPARC has done JOTA the past few years, and there's a covered pavilion there. Should it begin to precipitate, at least I'll be dry. The trees are not as tall; but they're tall enough for me to launch the PAR ENDFEDZ into.

At 62, I'm no young buck and no spring chicken. I don't need a case of pneumonia or bronchitis. No QRP contest is worth that! But I can dress for the cold, as long as I can stay dry.

Stay tuned!

Bumfuzzled

bumfuzzle[ buhm-fuhz-uh l ]
verb (used with object), bum·fuz·zled, bum·fuz·zling. Chiefly South Midland and Southern U.S.
– to confuse or fluster.

Origin of Bumfuzzle

1900–05; bum- (expressive prefix, perhaps to be identified with the initial syllable of bamboozle) + fuzzle to confuse (perhaps expressive alteration of fuddle)

This is how I would characterize my reaction to this item appearing on the ARRL website on January 19, 2020. Just confused and flustered:



My own belief was that CEO Howard Michel WB2ITX was doing a necessary and deliberate job in changing the operational focus of the League’s office and services. The main goal as he stated publicly was to increase the value of League membership. He was a very successful CEO of the much, much larger and more complex association, IEEE.

As a Presenter on the ICQ Podcast, I’ve had the opportunity to regularly interview Howard after each Board meeting of the ARRL so as to get our listeners updated on Board actions that had occurred and were being rolled out. I put him on the spot each time, asking what he had done to increase the value of membership. He always responded with an articulate set of accomplishments and plans. As a Life Member of the League, I thought he was doing a great job, especially walking into an opening where his predecessor was ousted after only a couple of years, amidst much rancor and consternation by members and non-members alike. So I’m bumfuzzled.

League officials, including the just re-elected President, have stated that it’s a personnel matter so there is no public comment. Others engage in conjecture, based upon the nefarious “I heard…” source of information that always occurs in the absence of factual source-based statements. I’ve heard a lot, too. And from a wide range of sources. But not much that is public.

The recent emergence of a “backlash group,” coming on the heels of the previous CEO hiring, censure of a Board member, and the attempted change of officers getting a vote on matters in addition to the long-standing votes of Board members, has pressed for greater openness in League business. This group stated that transparency in League actions is paramount. The myARRLvoice group states the following on it’s web-page:

This group had a couple of supporters get elected to the Board in a recent election. We will see how these two Directors, especially, act to publicly announce how they voted regarding election of the CEO Howard Michel WB2ITX. It’s on the “I heard…” rumor mill that the vote was 9-6 to not re-elect Michel. How did each Board member vote? I asked my Director, David Norris K5UZ, how he voted. Note: I serve as one of his appointed Assistant Directors. He told me that he voted to retain Howard and thought he was doing a fine job. So that is one vote now made public.

How did your Division Director vote? If you don’t know, ask them! And why? Did they take your views into account in the run-up to this Board meeting? They are your voice on the ARRL Board, if you’re a member of the League.

Hunting For NDBs In CLE252

AP-378 Mayne Island, BC



How time flies. Once again it's a CLE weekend. It seems like the last one was just a week ago!




'CLE's are 'Co-ordinated Listening Events, and NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.

This time the hunting ground is the 15 kHz slice from 370.0 - 384.9 kHz.

This is a somewhat dreaded range for me since my local blowtorch NDB, 'AP' (378 kHz), sits right in the middle of the range. 'AP' is located at the entrance to Active Pass, the main ferry route to Vancouver Island, and the antenna is about 3/4 of a mile down the beach from me. Needless to say, the beacon is about 40db over S9! With careful loop nulling, I can reduce this by about 25db but it's still an enormous signal to deal with.

Hopefully you can put 'AP' in your own log this weekend but its 25-watt signal will be much weaker for you. It's been logged as far east as Illinois and with your receiver in the CW mode, can be found on 378.399 kHz.

Things seem geomagnetically quiet at the moment but we are due for another blast on January 21st ... hopefully things settle-down for the weekend event.

From CLE coordinator Brian Keyte (G3SIA), comes the following CLE info:


Hello all

Here is your Early Advice of our next Co-ordinated Listening Event.
We are back to a normal event looking for the NDBs in a narrow and
fairly relaxing frequency range.  Beginners, occasionals and regulars
are all very welcome to join in.

    Days:    Friday 24 January - Monday 27 January
    Times:   Start and end at midday, LOCAL TIME at the receiver
    Frequencies:   370 - 384.9 kHz

Just log all NDBs you can identify that are listed in the range (it includes
370 kHz but not 385 kHz)  plus any UNIDs that you come across there.
We last had a close look at this frequency range in CLE236 at the end of
September 2018.

Please look out for the full Final Details in a few days, including how to
present your log, etc.


Please send your CLE log to the List in a plain text email if possible(not in an attachment) with CLE252 and FINAL at the start of its title.
Show on each log line:
    # The date (e.g. 2020-01-25, etc., or just 25) and UTC
          (the date changes at 00:00 UTC)
    # kHz  (the nominal published frequency, if known)
    # The Call Ident.

Show those main items FIRST - other optional details such as Location
and Distance go LATER in the same line. 
If you send interim logs, please also send a 'FINAL' (complete) log.

As always, tell us your own location and brief details of the equipment
that you were using during the weekend.

To help you to plan your listening, seeklists and maps for your part of the
World are available via the CLE page  http://www.ndblist.info/cle.htm

Good listening - enjoy the CLE.

Location:  Surrey, SE England       (CLE coordinator)
------------------------------------------------------------------

If you are interested in some remote listening - maybe due to local difficulties - you could use any one remote receiver for your loggings, stating its location and with the owner’s permission if required. A remote listener may NOT also use another receiver, local or remote, to make 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
Final details can be found at the NDB List website, and worldwide results, for every participant, will be posted there a few days after the event.


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!
