Encore – Classical Music on Shortwave on Sunday

Encore – Classical Music this weekend is being broadcast as usual by Channel 292 (Europe) on 6070 kHz at 15:00 UTC Sunday 30th June.
And by WBCQ on 7490 kHz at 00:00 – 01:00 UTC Monday 1st July
There is a repeat on 6070 kHz on Friday 5th JULY at 19:00 UTC.
This week’s show has plenty of xylophone, a horn trio, some Tennyson set to music, and a Vivaldi piece for mandolin. There is a string quartet, some Tchaikovsky, and a Strauss lieder.
All very wonderful.
Please note – Radio Tumbril is on the road being thoroughly analogue for a few weeks so there will be no emails but for a while but Encore will be broadcast every Sunday and Friday as usual – plenty of treats in store.
Thank you for spreading the word about Encore – Classical Music on Shortwave.
Please continue to send in reception reports and requests for pieces of music to play on Encore.
Brice Avery – Encore – Radio Tumbril.
Regular Broadcast times are:
15:00 – 16:00 UTC Sunday, and repeated 19:00 – 20:00 UTC Friday on 6070 kHz (Channel 292 Germany).
00:00 – 01:00 UTC Monday on 7490 kHz 9WBCQ – Maine).
Both Channel 292 and WBCQ live stream if reception is poor. And KiwiSDR’s world-wide network of online receivers do a great job too.
All easily found with search engines.

Can you identify this Hallicrafters model onboard the Columbine III?

Many thanks to SWLing Post contributor, Robert Yowell, who writes:

I was visiting the US Air Force Museum [Friday] and walked through “Columbine III” which was the Lockheed Constellation used as Air Force One by President Eisenhower from 1954 until he left office. In the back of the cabin was a nice cozy area where this Hallicrafters receiver was installed – ostensibly for the passengers to listen to news or other events while in flight.

I am sure one of your readers will be able to identify which model it is.

Can you imagine flying in this gorgeous Lockheed VC-121E four prop aircraft and listening to HF radio from a built-in Hallicrafters set? Wow…

Thank you, Robert, for sharing these photos. The National Museum of the US Air Force is one of my favorite museums in the world. I bet I’ve visited it more than a dozen times over the past decade–always a treat and always something new to discover!

Post readers: Can you identify this Hallicrafters model?  Please comment!

Russia to test DRM over FM

(Source: Radio World via Michael Bird)

Russia will begin testing the Digital Radio Mondiale digital radio standard in the FM Band in July in St. Petersburg.

Russian firms Digiton and Triada TV are working with Fraunhofer IIS, RFmondial, chipmaker NXP and others to carry out the pilot.

The organizers will install a DRM-capable transmitter mid-July and begin regular simulcast broadcasts (DRM for FM) immediately after site acceptance checks are complete. The transmitter will reportedly be on air for six months and have an analog transmitting power of 5 kW and a digital output power of 800 W.[…]

Radio México Internacional to disappear

Many thanks to SWLing Post contributor, Tracy Wood, who writes:

Radio México Internacional will disappear (again)…web stream to sadly go away.

Tracy referenced this article (in Spanish) from El Sol de México. The following excerpt was translated to English via Google Translate:

A grim picture was presented to employees and workers of the Mexican Institute of Radio (IMER), since the budget cut would technically lead to “paralysis” and a labor liability of seven million pesos before the dismissals.

In an audio, which was obtained by El Sol de México, the workers and collaborators were explained that “the IMER does not have the capacity to hire anyone. Neither in fees nor as a freelance, ” he says.

[…]But the recount of the damages that the IMER will have for the lack of resources is that “four stations will disappear in their entirety: Radio Mexico International, World Music, HD Interference and Digital Jazz. There will be no hearing advocate, which is why article 259 of the Federal Telecommunications and Broadcasting Law is not followed. “

Very sad news. While RMI hasn’t been on the shortwaves since 2004, they have maintained a web presence.

Thank you for sharing, Tracy.

FCC: RM-11843 seeks creation of a new 8-meter Amateur Radio allocation

Many thanks to a number of SWLing Post readers who have shared links to this petition for rulemaking–created by Michelle KU3N–to create a new 8-meter Amateur Radio allocation.

I’ve included the author’s notice about this proposal and also a news item from the ARRL below. First, however, just a quick tip on filing comments via the FCC system:

Making a comment

If you’re interested in commenting on this petition, you can do so via the FCC Electronic Comment Filing System until July 26, 2019.

Using the system the first time is a little confusing–here’s a tip:

Open the comment form on the FCC Express Filing site.

Next, type in the filing number in the first field:

The filing number should auto-complete as you type. Once it has been selected (as in the screenshot above) continue filling out the rest of the form with comments and then submitting it. It’s pretty simple, but if you’re not used to the comment system, selecting the proper petition can be a little confusing.

Of course, the FCC also has the following help page: “How to Comment on FCC Proceedings

For more information about this proposal check out the articles below from the petition author at REC Networks and also a notice from the ARRL:

(Source: REC Networks)

Today, the FCC has assigned a rulemaking (RM) number to a Petition for Rulemaking filed by REC Networks, through its founder, Michelle Bradley, KU3N as RM-11843.

This petition calls on the Commission to work with the National Telecommunications and Information Aministration (NTIA) to allow for amateur radio operations in the 8-meter band. This petition was in response to activities taking place in ITU Region 1 where more administrations are starting to authorize very limited operation on 8 meters.  Ireland, Slovenia and South Africa have already granted amateurs regular access to all or portions of the band being asked for in the petition.   In fact, ComReg, the Irish regulator has even gone far enough to allocate virtually the entire VHF low band (30~49 MHz) for amateur radio use.

In the petition, REC/KU3N notes that this spectrum could be used for weak signal experimentation and general amateur use primarily along transatlantic paths using CW, SSB and digital modes such as FT8 and digital voice.  As no radios are currently manufactured for this band, it could encourage “makers” to design new equipment and antenna design.  REC/KU3N predicts low usage of this band except during scheduled activities such as Field Day and contests as well as periods of sporadic-E, high sunspot numbers and other periods with a higher maximum usable frequency.

In the petition, REC/KU3N is asking to use 40.51 to 40.70 MHz, allowing beacons, prohibiting repeaters and discouraging FM operation.

This spectrum is currently used by the Federal Government as part of an older channelized land mobile radio system, mainly by the Department of Agriculture for national forests and parks.  It is also used for federal and non-federal telemetry and wildlife tracking. The spectrum is also sporadically used by the military for short-range communication.  Industrial, scientific and medical (ISM) devices also operate in the 40.66 to 40.70 MHz area.  REC/KU3N notes that this spectrum would be of most interest to those who wish to conduct transatlantic experimentation and thus will have more amateur activity in the eastern USA where it is likely that federal use of this spectrum is more likely in the western USA.

Comments on this petition will be accepted by the FCC through their Electronic Comment Filing System until July 26, 2019.  Select proceeding RM-11843.

The FCC has put on public notice for comment a Petition for Rulemaking (RM-11843) that seeks the creation of a new 8-meter Amateur Radio allocation on a secondary basis. The Petition suggests the new band could be centered on an industrial-scientific-medical (ISM) segment somewhere between 40.51 and 40.70 MHz. The spectrum between 40 and 41 MHz is currently allocated to the Federal Government and, as such, within the purview of the National Telecommunications and Information Administration (NTIA). ARRL member Michelle Bradley, KU3N, of Maryland, filed the petition in May on behalf of REC Networks, which she founded and described in the Petition as “a leading advocate for a citizen’s access to spectrum,” including Amateur Radio spectrum.

“REC feels that the time is right for the Commission to open a Notice of Inquiry and eventually a Notice of Proposed Rulemaking, and in cooperation with the NTIA, this new band opportunity can be realized to spark the next generation of ‘makers’ in the fields of science, technology, education, and math (STEM), especially women and girls,” Bradley told the FCC in the Petition. “The more opportunities we give to make things, the more opportunities we have to build a pool of experts in STEM, right here at home.”

The Petition said the objective of a new band would be “an effort to foster experimentation into the propagation characteristics of this band midway between the 10- and 6-meter bands.” An allocation in the 8-meter band is available to radio amateurs in Ireland, where the Irish Radio Transmitters Society has developed a band plan for 40 – 41 MHz.

“REC perceives this spectrum can be used for weak signal experimentation and eventually general amateur use, especially along transatlantic paths using CW, SSB, digital modes such as FT8 and digital voice,” the Petition said. “As no radios are mass-produced for this band at this time, this opens up new opportunities for ‘makers’ to construct transmitters, receivers, and antenna systems that can be used in this spectrum.”

REC anticipates “very low” usage of the new band, “with peak usage around sporadic-E episodes, operating events such as ARRL Field Day, and VHF contests, as well as during the peak of sunspot cycles,” Bradley told the Commission. “[W]e feel that the sharing of 40 MHz can be accomplished in a manner that serves the needs of the Amateur Radio Service while meeting the organizational missions of Federal Government agencies that utilize this spectrum.”

Interested parties may file short comments on RM-11843 via the FCC’s Electronic Comment Filing Service (Express). Visit the FCC “How to Comment on FCC Proceedings” page for information on filing extended comments.
