The Flight of the Blue Eagle

 
Commando Solo/via Military.Com

Jeff: The use of U.S. military aircraft for clandestine radio broadcasting was cloaked in secrecy for a period that spanned some 60 years.  Today in Wavescan, Ray Robinson brings us the fascinating story of “The Flight of the Blue Eagle”.

Ray: Thanks, Jeff.  It all began back in 1962 during the Kennedy era and the Cuban Missile Crisis.  During the crisis, a large cargo plane operated by the United States Navy was hurriedly stowed with broadcasting equipment and flown over the waters separating Florida and Cuba.

For these inaugural broadcasts, a radio receiver in the cargo plane took an off-air program feed from the new Voice of America medium wave station at Marathon in Florida.  The ground-based VOA channel was 1180 kHz, and the airplane re-transmitted this programming on 1040 kHz.  Interestingly, the 50 kW transmitter in Marathon, Florida isn’t mentioned in the WRTH until the 1964 edition, although it is known to have been operational since at least 1962.

Since that historic, though unannounced, beginning, airplanes have been used for local broadcasting in the medium wave, FM, TV and shortwave bands, while flying over at least a dozen different countries.

Two years later, in the summer of 1964, a series of mysterious radio broadcasts were heard by DXers living in the central coastal areas along the Atlantic seaboard of the United States.  These broadcasts were first noted on the shortwave channel 19100 kHz, and later on 532 kHz at the extreme low end of the medium wave band with identification announcements as “The Blue Eagle”.  Programming consisted of their own presentation of popular music, and sometimes a relay of local medium wave stations such as WLDB and WMID in Atlantic City, New Jersey.

Subsequent information revealed the fact that these broadcasts from “The Blue Eagle” were actually test broadcasts from a DC-6 airplane ahead of potential transfer to Vietnam for use as an aerial broadcast unit.  It should be noted that the Blue Eagle is a symbol of the United States Navy.

Now here in Wavescan, we did briefly mention this topic some 24 years ago back in 2001, and after that program aired, we received a response from Steve Robbins in the USA who said he was one of the engineers who designed, fabricated, and operated what he referred to as “Project Jenny”.  Here is his summary:

1962: The two original C-118 aircraft were based out of NAS Patuxent River in Maryland and the electronic equipment was temporarily installed in the two aircraft, numbered 611 & 429.  These two planes carried radio relays from Voice of America for listeners in Cuba.

1965: The electronic equipment was re-installed in two Super Constellation aircraft and a second round of test broadcasts were made over the DC Maryland areas with identification announcements as “Blue Eagle”.  Steve Robbins was on this aircraft at the time.

1966: Four Blue Eagle aircraft were flown out to Vietnam, where they relayed programming in English & Vietnamese.  When the 50 kW VOA medium wave station at Hue in central Vietnam was raided and captured by the North Vietnamese, Blue Eagle took over the relay of VOA programming on the same channel, 760 kHz.

After the Vietnam War, the broadcast equipment was removed from the older aircraft and fitted into new aircraft of the same type, Super Constellations, and they were re-designated as “Coronet Solo”.  Several years later again, new and updated aircraft were commissioned and they have been on the air over Serbia, Afghanistan and Libya as “Commando Solo”.

And that’s the end of what Steve Robbins was able to tell us.  But from our own research, it appears that a total of six Lockheed Super Constellation C130 aircraft were fitted out with similar equipment in the 1960’s for the purpose of aerial broadcasting, and from 1968 on they were operated by the 193rd Operations Wing of the Pennsylvania Air National Guard.  In 2003, new EC130-J Constellation aircraft replaced the original 30 year old planes, though the same electronic equipment was transferred from the old planes into the new.

Each of the radio broadcasting airplanes contained a bevy of electronic equipment, including three 10 kW broadcast transmitters for use in the medium wave and FM bands.  Some planes were also equipped with 2 kW TV transmitters and/or shortwave transmitters.  Electric power for all of the onboard electronic equipment was generated by four generators driven by the propeller engines on the aircraft.

Although the original test broadcasts identified on air as "The Blue Eagle", this radio broadcasting network of six Constellations came to be known collectively as “Commando Solo”.  On each occasion of active deployment, the on-air identification used was changed to meet local circumstances.

When flying over Vietnam during the Vietnam War, the Blue Eagles identified as “AFRTS, the American Forces Radio TV Network”.  In Vietnamese, their programming identified as VPMF, “The Voice of Patriotic Militiamen's Front”.
In 1994 during the United Nations-backed invasion of Haiti in an attempt to restore democracy, radio programming from the U.S. aircraft was identified in French as “Radio Democracy”.  While flying over Serbia and Bosnia, the identification was "Radio Allied Voice", and in the Gulf War, it was "Voice of the Gulf".

The mission of the Air Wing was to win the hearts and minds of adversaries and to provide vital information to allies, refugees and victims in times of crisis.

In the early 2000’s, Commando Solo was pressed into service again over Afghanistan.  During that mission, the United States began a series of radio broadcasts to the people of Afghanistan, using a total of seven different airplanes for the purpose.  According to a report from BBC Monitoring, these broadcasts were first heard on October 14, 2001, just one month after “9/11”.

Those airplane broadcasts were heard in Afghanistan on two medium wave channels, 864 and 1107 kHz, which were the channels previously used by Radio Afghanistan in Kandahar and Kabul.  The broadcasts were in alternating languages, Dari and Pashto – the two official languages of Afghanistan.  The program feed to the airplanes could be heard on 8700 kHz shortwave in upper sideband mode, though it was not disclosed where that transmitter was located.

These planes have also flown on active broadcast missions over several other countries, including the Dominican Republic, Panama, Grenada, Somalia, Iraq and Libya.

Here’s an off-air recording of a broadcast made to the people and military forces of Libya, recorded on July 13, 2011.  It alternated between English and Arabic, but we’ve removed most of the Arabic.

Very few QSLs have been issued for these unique broadcasts, though at least three QSLs are known.
QSLs from American "Blue Eagles" and "Command Solo" Planes
C.  M.  Stanbury, USA, 1962, 1040 kHz, flying over Cuba, ID as VOA, VOA QSL card
Terry Krueger, Florida, 1994, 1035 kHz, flying over Haiti, ID as "Democracy," QSL letter
Clive Rooms, England, 1999, 1270 kHz, flying over the Balkans, ID as "Allied Voice," QSL letter

The final broadcast of Commando Solo came on September 17, 2022, just before the EC-130J’s were decommissioned at the Community Days Air Show at Lancaster Airport in Lititz, PA.  A final flight was made, and the final broadcast was transmitted to the ground and played at the Air Show.  In the transmission, the Wing thanked the local community for their support over the years, before broadcasting the Santo and Johnny song, ‘Sleepwalk’.  The transmission ended with the phrase “Commando Solo, music off.”

Back to you, Jeff.

UK Propagation Update

RSGB
GB2RS News Team | March 28, 2025
Last week’s space weather was dominated by a large coronal hole on the Sun. This was probably one of the largest we have seen for many years.
Moderate, G2, geomagnetic storming was observed following the arrival of a solar wind stream from the hole, with the wind speed exceeding 600 km/s on Wednesday 26 March. This pushed the Kp index to 6.33, depressing the MUF slightly.
Luckily, the daytime MUF over a 3,000km path mostly stayed above 28MHz, but it was slow to rise on Thursday the 27 March, when it took until 0900UTC to reach 28MHz. At the time of writing, the solar wind speed was in excess of 800km/s, so we can expect more disruption until at least Saturday 29 March.
Meanwhile, the solar flux index declined to 152 by Thursday 27 March, with only four small sunspot regions visible.
CDXC members have been discussing working New Zealand in the morning at the ZL sunset, often on low power. Listen and look for ZL4OL and ZL2CC, usually on FT8, but if conditions allow CW and SSB. 20m or 40m seem to be the favourite, and the VarAC data mode seems popular in ZL as well.
Next week, NOAA predicts the solar flux index will climb again, perhaps to 180 by the 4 April. However, unsettled geomagnetic conditions are forecast again, beginning on the 3 April. We may expect the Kp index to reach six, which could be the start of at least ten days of disruption.
VHF and up :
The overall picture for the weather patterns in the coming week is that of high pressure, which means that Tropo should be available as a good mode for VHF bands.
There can be quite strong temperature inversions in the region of large well-developed areas of high pressure. The best performance will usually be around the edges of the high where the height of the inversion and ducting layer is typically between 0.5km and 2km above the ground, and can cover large distances for excellent DX prospects.
Occasionally, a shallow ducting layer can form near the ground overnight but often disperses by mid-morning. If you are in a good inversion region, try SSB or CW on the VHF/UHF bands, as paths of up to 1,500km can often be achieved from a good ‘tropo lift’.
The reverse side of the high-pressure systems is that we will have low pressure nearby, mainly to the north and west of the UK. Any potential for rain scatter will mainly be over northwestern Britain, although an active front that was moving south on Friday 28 March was a good candidate for chance rain scatter on the GHz bands.
The prospects for meteor scatter are still largely dependent upon random meteors, which are usually best in the hours before dawn. Current solar activity will continue to trigger auroral alerts in the coming week.
Now onto Sporadic-E, and last week we had a few out-of-season isolated foEs ‘blips’ to between 5-7MHz, which was enough to produce propagation on 10m and 6m, albeit very fleetingly.
There have already been some equinox-related 6m trans-equatorial propagation or TEP workable from the Southern part of the country, so keep an eye open late morning for Africa and late afternoon for South America.
EME path losses have continued to improve until perigee this morning, the 30 March. Moon declination is still falling, and reached a minimum last Friday, the 28 March. Moon windows will increase throughout the coming week. 144MHz sky noise is low, apart from Saturday 29 March when the Sun was close to the Moon in the sky, rising to moderate next Thursday before dropping back to low for the weekend.

Trump admin offers Voice of America employees buyouts as judge blocks it from being shut down

 

Just as a federal judge issued an order blocking the administration’s efforts to dismantle the broadcaster, U.S. Agency for Global Media staffers received an email offering them a renewed opportunity to sign up for the ‘Fork in the Road’ deferred resignation program

A federal judge in New York City granted a temporary restraining order on Friday to several Voice of America journalists attempting to stop the Trump administration from shutting down the international broadcaster on the grounds that the move is unlawful and unconstitutional.

Radio Free Asia says it will fully shut down by the end of April without court intervention



WASHINGTON, March 28 (Reuters) - Radio Free Asia said on Friday it would shut down by the end of April if the courts did not prevent the Trump administration from cutting its funding.
The agency, which is in a legal battle with the administration in an attempt to remain operational, filed a motion to stop the government's termination of funding and ensure access to funds appropriated by Congress.

Update on status of Voice of America

 


Voice of America wins in court, for now, as judge blocks Trump administration from firing staff

NEW YORK (AP) — The Voice of America can’t be silenced just yet.

A federal judge on Friday halted the Trump administration’s efforts to dismantle the eight-decade-old U.S. government-funded international news service, calling the move a “classic case of arbitrary and capricious decision making.”

Judge James Paul Oetken blocked the U.S. Agency for Global Media, which runs Voice of America, from firing more than 1,200 journalists, engineers and other staff that it sidelined two weeks ago in the wake of President Donald Trump ordering its funding slashed.

Oetken issued a temporary restraining order barring the agency from “any further attempt to terminate, reduce-in-force, place on leave, or furlough” employees or contractors, and from closing any offices or requiring overseas employees to return to the U.S.

Brazil's Rádio Nacional to begin Spanish/English slot

 

Rádio Nacional premieres international track in Spanish and English

Starting March 31, Rádio Nacional da Amazônia will debut an international program on its schedule, aimed at audiences from other countries who follow the program via shortwave. The 10-minute programs in Spanish and English will air daily at 10:50 pm

The creation of the Brazil National - International Service band came from QSL requests received by the broadcaster. QSL cards are postcards used by radio amateurs to confirm contacts made via radio. They function as a kind of communication "receipt" and are exchanged between radio operators in different parts of the world.

Because it operates on shortwave (SW), Rádio Nacional da Amazônia is the only radio station in the country that can have national and even international coverage. It potentially reaches 60 million inhabitants, with a signal that reaches the entire northern region, as well as Maranhão, Piauí, Bahia, Minas Gerais, Mato Grosso, Goiás and other states. The radio station strengthens the link between the communities of the Amazon, integrates the region with other states in Brazil, and values cultural diversity. diversity.

Highlights of Solar and Geomagnetic Activity 17 - 23 March 2025

Solar activity was at moderate levels (R1-Minor) on 17, 19 and 21 March. Region 4033 (N24, L=122, class/area Bxo/010 on 15 Mar) produced an M1.0/1f at 17/1933 UTC. This event produced a northerly vector CME with a possible weak Earth impact. Region 4031 (N16, L=165, class/area Eai/120 on 19 Mar) produced an M1.5/1n at 19/2040 UTC. Region 4028 (S17, L=141, class/area Dai/240 on 15 Mar) produced an M1.2/1n at 21/1558 UTC/ Associated with this event was a Type II sweep with an estimated velocity of 504 km/s. At about the same time as this flare, a fast shock signature CME off the SE appeared to have originated from the vicinity of Region 4034 (S12, L=112,
class/area Cso/020 on 20 Mar). 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 17 and 18 March with a peak flux of 6,680 pfu at 17/1600 UTC. Low to moderate levels were observed on 19-23 March. 

Geomagnetic field activity was at quiet to unsettled levels on 17-18 March and quiet to minor storm (G1-Minor) levels on 19 March. This activity was attributed to negative polarity CH HSS combined with CME effects. Quiet levels were observed on 20 March. Activity levels
increased to unsettled to minor and moderate (G1-G2/Minor-Moderate) storm levels on 21-22 March. This activity was attributed to the 17 March CME and negative polarity CH HSS effects. Quiet to active levels were observed on 21 March due to waning CME effects. 

During the highlight period, Bt peaked at 40 nT and Bz dipped south to -17 nT late on 21 March. Solar wind speeds generally peaked to 525 km/s mid to late on 19 March and again late on 22 March to early on 23 March. 

Forecast of Solar and Geomagnetic Activity 24 March - 19 April 2025


Solar activity is expected to be at a chance for R1-R2 (Minor-Moderate) levels through the outlook 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 27-31 March and 06-14 April. Low to moderate levels are expected on 24-26 March, 01-05 April and 15-19 April. 

Geomagnetic field activity is expected to be at active to G1-Minor levels on 24 March due to CME effects. G1-G2 (Minor-Moderate) levels on 25-26 March and unsettled to active levels on 27-29 March are forecasted due to positive polarity CH HSS influence. A combination
of unsettled to G1-Minor levels are forecasted for 04-19 April due to negative polarity CH HSS influence.

Log Country Radio - before it's too late !

 

In the Czech Republic, Country Radio has to stop broadcasting on the medium wave frequency 639 kHz after about a year and a half.

This will happen on March 31.

In 2023, the radio station received two of the old AM frequencies from the public broadcaster ?Ro, which switched off its AM transmitters on January 1, 2022.

The transmitter in Liblice (near ?eské Brod) uses the impressive twin antenna masts of 355 meters, the tallest construction in the Czech Republic (photo: Wikipedia ).

Although the power of Country Radio was about 30 times smaller than the public broadcaster's previous one, it still provided a decent AM coverage in Prague and Central Bohemia.

According to the German radiomuseum.org, the city of ?eské Brod has already issued a demolition permit for the masts.

Country Radio will continue to broadcast on the other medium wave transmitter in ?eské Bud?jovice (954 kHz), for parts of South Bohemia.

U.K. Propagation Update

 


RSGB
GB2RS News Team | March 21, 2025

Last week was pretty unremarkable from an HF perspective. After the disturbed geomagnetic conditions on the 12 to the 14 when the Kp index rose to five, conditions were a little more settled.

The solar flux index hit 204 on the 17 March but then declined back to the 180s.

Having said that things were settled, the Kp index did exceed four for three periods on the 19 March, peaking at 4.67. This had the effect of reducing the MUF over a 3,000km path to 21-24MHz.

We also had two M-class solar flares on the 17 and the 19 March, with the latter causing a coronal mass ejection that may give Earth a glancing blow around the 22 March.

As spring progresses, we may find the F2-layer MUF dropping as we move to summer ionospheric conditions, perhaps to be replaced by enhanced sporadic-E conditions on 10 metres instead.

Next week, NOAA predicts that the solar flux index may drop further, perhaps hitting 150 on the 28 March. Unsettled geomagnetic conditions are forecast for the 25 to the 28 March, with a maximum Kp index of five.

As we said last week, this is now a peak period for auroral activity, given the angle that the Earth makes with the Sun. The ‘Russell-McPherron’ effect is down to the alignment of the Sun and Earth around the spring and autumn equinox and means that you are twice as likely to experience the aurora in spring and autumn than in winter and summer.

VHF and up :

The recent fine weather has provided some useful Tropo. This has been mainly towards the east and into the near continent, which seemed like nice timing for the 1.3GHz UK Activity Contest last Tuesday evening.

Despite this, many participants reported conditions as poor. The high is now moving away and by the time you hear this, it will be a predominantly low-pressure weather sequence from now on. This means limited Tropo in the coming week, and rain scatter comes to the fore as a mode of choice if you have a GHz band set up.

The solar conditions continue to provide a trickle charge of auroral alerts, but not enough for any significant operating advantage. As usual the message is to keep on top of things by monitoring the Kp index for values in excess of 5.

Meteor scatter remains largely in the gift of random meteors, so it’s an early start to catch the pre-dawn peak of random meteors if you are so persuaded.

Lastly, a mention of Sporadic-E which is still in its close season. We have a while to wait until later next month when we could expect the occasional stirrings on 10m.

EME path losses continue to improve until the Moon’s perigee (its closest point to Earth) on the morning of the 30 March. Moon declination has been falling, reaching a minimum yesterday, the 22 March.

So again, we have short Moon windows and reducing peak Moon elevation. 144MHz sky noise started high on Friday the 21 March but will drop back to low by the middle of next week.
