The following blog was originally posted in 2015 but might still be of interest to anyone with a shortwave radio! Since the migration of HF aero traffic to satellite has been slow, there is still a lot of oceanic traffic to be monitored on the bands, 24/7.

                  **************************************

Unlike the growing scarcity of good HF maritime DX targets, there is still a large amount of HF aero activity to enjoy! Even with the move to satellite comms, there is still, at any given time of the day or night, hundreds of aircraft using HF radio to communicate with controllers, companies and home bases. Both commercial aviation and the military, as well as many privately owned aircraft, use the HF communication networks to keep them flying safely. From trans-oceanic 777s' and military transports to single engine float planes in the Canadian Arctic and Alaska, the sky is alive with DXing opportunities!

A huge percentage of commercial aircraft are delegated to moving freight and many of them can be heard on HF radio. Many of the planes in use are retired passenger planes that have been reconfigured for moving cargo. Back when I did this type of listening, older DC-8s seemed to be particularly popular, especially on the nightly South / Central America to Florida routes. I suspect that nowadays, these have been replaced with older DC-10's and 747's.


'FINE AIR 432' was logged on March 24,1996 at 0435Z while working Miami Radio on 6637kHz. The DC8-51F (Freighter) was over Bogota while enroute from Lima to Miami.




'NIPPON CARGO 083', a 747-200F, was logged
on 8891kHz working Baffin Radio. They were reporting position "LT", a waypoint above Alert, at 82-31N / 62-12W, westbound on Polar Track "Quebec".
The freighter was enroute Amsterdam to Anchorage.



The Antonov 124-100 is a gigantic Russian built freighter - capable of transporting in excess of
120 tons. This is aircraft "RA-82045" which was logged as 'HEAVYLIFT 878' in June, 1996.



Operated by Volga-Dnepr, 'HEAVYLIFT 878' was working Dakar (Senegal) Aeradio on 6535kHz reporting FL240 and position 13-14N / 24-26W enroute Cape Verde Islands to Sao Paulo, Brazil.


'AFM 01' was a DC8-55F logged while working Brazzaville Radio (Congo) on 8903kHz. It was at FL350, enroute Harare, Zimbabwe to Kano, Nigeria at the "MPK" waypoint, 250 miles east of Kinshasha, Zaire. Brazzavile was advising of 'crossing traffic, same level...please say intentions'... Yikes!

On another evening I heard the Dakar (Senegal) controller advise a British Speedbird 747 to 'go to flight level 330 ... please go now ... go very very fast'.


'AFM01' (Affretair) was Z-WMJ, shown here on final approach to Gatwick.



'PACIFIC AIR EXPRESS 3517' was heard on 8867kHz working Brisbane Radio while over the Coral Sea. The Lockheed L-188C four-engine turbo prop was enroute Honiara to Brisbane with a load of fresh tuna destined for the Japanese market. N360Q, shown on the ground at Honiara, was leased from the states and operated by Charrak Air.



The U.S. military is still active on HF radio and some interesting catches can be had. During the testing phase of the 'cruise' missile, the missile navigation systems were tested over the Northern Territories and Alberta. Once dropped from their B-52 launch platforms, the missiles were tracked across Alberta by Advanced Range Instrumentation Aircraft (ARIA). 'AGAR 93' was heard on one such mission on 11176kHz. 'AGAR 93' was # 81-0893, an EC-18 (modified Boeing 707) out of Wright Patterson' 4950th Test Wing. According to the aircraft commander who signed my verification, the aircraft was approximately 1 hour S.E. of Namao, Alberta. One can easily see why # 81-0893, shown here, was affectionately known as "The Beast".


'DOOM 81' was a gigantic B-52H from the 96th Bomb Squadron, stationed at Barksdale AFB, LA. The appropriately named big bomber was heard on 11176kHz while working Ascension Radio and was just about to rendezvous with their mid-air refueler when the mission was aborted. This was the first and only B-52 that I was ever able to confirm.
'ROMA 99' was logged on 17975kHz while working Thule Radio. They were taxiing for takeoff at Dulles International in Washington D.C. and reporting a minor fuel-pump problem. 'ROMA 99' was a KC-135R Stratotanker, # 62-003512, from the 509th Air Refueling Squadron at Griffis AFB, NY.



'REACH 71839' was heard on 11176kHz while working Albrook AFB, Alaska. Tail # 65-0239, this 'REACH' flight was an aging C-141B Starlifter, at one point, the Air Force's major transporter. 'REACH 71839', out of McChord AFB, was enroute Brazil to Puerto Rico.


There's still plenty to be heard on HF, outside of the amateur bands and a quick internet search on 'Utility DX' will turn up several interesting and informative sites ... each one having an abundance of related links to follow. Here are some that will be helpful:

A few months ago, I challenged the ARRL’s new mission to serve members in a more effective way by bringing “value” to members. I suggested that one quick “win” would be to stop selling through Amazon (at a 55% discount) and use that money-per-book to fund “free shipping” for members who purchase books. Many readers just didn’t read beyond the title of “free shipping” before raining down the it-will-just-be-passed-along-to-members rhetoric. This does not understand that the League would make a greater profit margin by selling at the 100% retail price (even with whatever discount the member may receive by being a Certified Instructor, etc.), charging no shipping, and still recouping a higher profit than the automatic 55% “loss” through the standard wholesale discount.

In one of my interviews with Howard Michel ARRL CEO on the ICQ Podcast, he said he ran the numbers and that it wouldn’t work out. I did not directly challenge him on that issue since it’s clearly his call. My thought was that it was a pure and simple strategy to demonstrate his new vision of “increasing value.” But enough with my recommendations, already!

However, perhaps it’s just me, but has the ARRL increased their free or discounted shipping stance in marketing publications? Like other League members, I’m sure, I received the above coupon code for Cyber Monday (after Thanksgiving). It’s FREE SHIPPING on $50 or more. That’s an incentive, especially with the new Handbook out and discounted temporarily at $40. So, I thought I’d grab another discounted book to reach $50 or more and get a FREE SHIPPING discount. On my daily driver desktop, I run Linux Mint on a Dell T-5500 8-core CPU with 72GB of RAM and a gigbit Internet service via ethernet to my commercial class switch. I rarely ever have buffering of websites from my end. Ever. But, boy, did I on this Cyber Monday order at ARRL.org! It took several HOURS for me to get the order through to checkout. I tried several different machines, in addition, just to ensure it wasn’t on my end. It wasn’t as I did a network speed operation test on getting packets to and from the ARRL.org server. It was on that end…because, no doubt, there was a boatload of customers ordering. So that’s the point of marketing offers, no? And I’m very happy to see evidence of it drawing a crowd at the virtual checkout page at the League’s website.

And, here are several more adverts e-mailed to members, all with $5 discounted shipping. So, has the ARRL been rolling out a version of this “free shipping” strategy? Well, only some offers reflect actually free shipping but a cap at $5 shipping is also a winning offer, too. I’m delighted at this marketing move by ARRL Product Development Manager Bob Inderbitzen, NQ1R. Keep it up, Bob! This increases value to members who receive the code coupons.

ARRL announced today that they have filed comments with the FCC requesting a dismissal of the Petition for Declaratory Ruling filed by New York University (NYU) regarding digital encoding and encryption.  This petition basically claims that proprietary and closed protocols like PACTOR violate current FCC rules, an opinion I’ve had for several years.  I think the AMBI vocoder used in D-STAR and other digital voice modes falls into the same category as well as it’s not openly documented, like the rules require.  Due to the lack of documentation and openness, such encoding is de facto encryption, which is prohibited.

ARRL’s filing has me smacking my head.  Rather than openly addressing the issue of protocols in amateur radio that are closed and proprietary, they attack the language proposed by the Petition.  Furthermore, they pull CW into this, stating,

“The proposed prohibition arguably could include, presumably unintentionally, CW (Morse Code), which is a longstanding means of encoding transmissions. The very fact that messages sent in CW are “encoded” by any definition of the term starkly demonstrates the problem with this proposal.“

I’m not sure if ARRL is intentionally being obtuse or just doesn’t understand the crux of the issue with “un-openly” documented digital protocols.  CW, while technically encoding, is 100% openly documented, and has been for a century or more.  It doesn’t require proprietary hardware, software, or algorithms to decode.  PACTOR until most recently could only be decrypted with proprietary hardware.  AMBI and others continual to be closed protocols.  That’s the problem, not semantics over the proposed language in the petition snagging CW as encoding, and encryption.

A few weeks ago I started writing comments to file with the FCC, but I quite honestly lost interest.  I don’t have a horse in this race, other than wanting to see amateur radio continue on well into the future.  I’m just disappointed ARRL doesn’t get what the real problem is, doesn’t make an effort to correct it, and fails to even acknowledge that closed digital protocols are antithetical to the openness and historical foundation of amateur radio.

The line-up of speakers for the Wes Schum W9DYV Radio Symposium at the St. Louis area Winterfest 2020 has now been finalized. Nick Tusa K5EF, coordinator for the Symposium, was pleased to announce that long-time boat anchor operator and aficionado Lynn Fisk, K5LYN is the final speaker.

Lynn Fisk grew up in the Texas Panhandle in the 1950s/early 1960s and enjoyed playing with radios since an early age. Amateur radio has been his life-long passion after earning his General Class ticket at age 15. Lynn was drawn to the early Central Electronics exciters developed and sold by Wes Schum W9DYV that were on the air everywhere in those days. However, he had to grow up, go to college and become a professional in Latin America History first! He eventually moved into the healthcare industry, later retired from the State of Texas in 1997 and resides in Austin, Texas.

Since retirement, Lynn has been a full-time restorer of vintage radio equipment and avid homebrewer. His more recent projects have included the design of transceiver adapters for 9MHz phasing exciters and the construction of medium-power linear amplifiers.

Lynn is extremely active in the vintage radio community while serving as one of the net control stations for both the Boatanchors Unlimited and Vintage Sideband HF nets. His nets are quite lively and often start off with a short description of how the early days of single sideband progressed in the 1950s-70s.

Nick Tusa said, “The Symposium is enhanced significantly by Lynn’s agreement to speak in the final slot on the program. His long background and standing in the ‘boat anchor’ community will supplement what our other fine speakers contribute to this year’s program at Winterfest 2020.”

K5EF also has a lengthy history with Wes Schum’s SSB and Central Electronics equipment. Nick started his adventure into Amateur Radio in 1963 as a novice class attendee at the Jefferson Amateur Radio Club. First licensed as WN5NID and later WA5RMC, Nick’s interest in Ham Radio led to an Electrical Engineering degree from Tulane University and a 40-year career in Radio/Microwave system engineering.

A life-long resident of the New Orleans area, Tusa Consulting Services – the firm he founded – has developed and implemented numerous public safety conventional and trunked analog and digital voice/paging radio systems throughout the US. Nick’s hobby interests – aside from Triumph sports cars – include antenna system design, homebrewing of HF equipment of all types, and the restoration of vintage radio gear (Collins, Central Electronics and TMC) and mechanical Teletype equipment.

All in all, this year’s W9DYV Symposium could be the best one yet! See videos from last year’s speakers for a flavor of the event held then in Slidell, LA. Make you plans now as this is a growing hamfest sponsored by the St. Louis and Suburban Radio Club.

Twitter is such a wonderful source of knowledge and a great place to pick up amateur radio operating tips. I saw this post from Johnny/W5KV, talking about getting a 146.52 sticker for his truck. (146.52 MHz is the 2m National Simplex Calling Frequency.) I’ve written about these stickers here: Get Your Mobile Frequency Sticker On

These oval stickers originated in Europe, to indicate the country where a vehicle is registered. In general, these oval stickers have become popular for indicating all kinds of things, including country, state, airport code, national park, etc. One of the most common stickers you’ll see has “26.2” on it to indicate the distance in miles of a marathon run. In other words, it means “I ran a freaking marathon” or maybe “I want you to think I ran a freaking marathon.” You’ll also see “13.1” to indicate the completion of a half marathon.  Hence, W5KV’s comment about 6 full marathons. You will see other numbers used on these stickers, such as “5.56” for you firearms enthusiasts.

So I posted this photo of the back of my truck. My 146.52 is actually a magnetic sign, not a stick-on label but the intent is the same.

But of course, radio amateurs are always innovating to find new ways of doing things. Michael/K2MTS posted this photo of his vehicle with a dust-enabled 146.520 indicator on it.

Like many brilliant innovations, I immediately realized the advantages of using vehicle dust to indicate operating frequency:

• No cost to implement
• Flexibility: the frequency can be easily modified
• Text messages can be appended, such as “CQ CQ” or “Call Me”

One disadvantage is that it requires your vehicle to be dirty but that seems like a minor obstacle, easily overcome by a short drive down a dirt road.
