TIVAR Hardware Test

Kim Andrew Elliott from VOA Radiogram has recently been unsure as to why some people decoding the VOA Radiogram have issues with Olivia 64-2000 modes even though this mode should
be much more robust than MFSK32.

Christopher, K6FIB believes that the performance of decoding Olivia 64-2000 may be dependant on the processing power of the PC or mobile device. He carried out a test with the TIVAR
Android app and two different android devices. Christopher says:

I have been using a Wiko Sunset2 4GB Android smartphone as part of a lightweight and compact ("hiker biker") portable receiving station for VOA Radiogram and Digi_DX. However, this
device seems unable to demodulate signals in the Olivia 64-2000 mode when using the TIVAR app.

To investigate this problem a comparative "shoot-out" test was conducted with three different Android 4.x.x. devices (one of them being the Wiki Sunset2) all running the same release of
TIVAR, and an MP4 recording of a fragment of VOA Radiogram broadcast nr. 147 (from my archive).

Now we have an article from LatvianHistory.com about Shortwave radio monitoring by the KGB in Latvia written by Maris Goldmanis.

Soon after the end of the World War 2 the tensions between Soviet Union and United States of America engulfed into Cold War. A full-scale war of propaganda was used by both side
including shortwave radio broadcasts. Shortwave radio broadcasts could reach listeners to faraway locations including the Soviet occupied Latvia.  Soviet security services were unable to
control the foreign broadcasters so they tried to jam the broadcasts or to punish the listeners. But in either way it was never-ending carousel as Soviet radio industry made shortwave radio
receivers in masses and neither the technical jamming or KGB monitoring could not fully block the western propaganda.

Shortwave radio broadcasts were popular among Latvians because many of them were critical of the soviet mass media content and therefore they seek alternative news sources. In first
post war years radio was still a rare household item, as may pre-war Latvian and German-made radios were lost and Soviets attempted to register the radio owners. The average shortwave
listener needed to know English, German and Russian although some of their news were transcribed in the national partisan underground newspapers and leaflets. However, the circulation of
these newspapers were quite low. So radio owners tried to listen to Radio London, Voice of America, Radio Luxembourg and Radio in American Sector, that transmitted from Western
Germany. After the Winston Churchill Iron Curtain speech in May 24 1946 in Fulton the BBC World Service started broadcasts in Russian. From September 2 1948 Radio Vaticana started
broadcasts in Latvian.
Soviet authorities listened and discussed these broadcasts themselves. Since the content of these broadcasts were beyond their control they started to build powerful jammers. Their
technical operation is discussed in separate post. War in Korea triggered the full-scale campaign of truth against the communists and decided to boost nationalism within Soviet occupied Baltic
republics. On June 3 1951 the Voice of America begun to broadcast in Latvian. Latvians at first paid large attention to it, radio played the Anthem of Latvia and called for resistance making
many people to believe that US will send its support. However, it took place after the deportation of March 25 1949 and Soviet power had fully established itself in Latvia. Later people got
enough of repetitive information and lack innovation.

Soviet Ministry of Security gathered reports about people listening to Voice of America. Mostly they were discovered when they unknowingly talking about the broadcasts to a KGB agent or
their conversations were overheard. They were added to KGB list as persons as spreaders of the anti-soviet propaganda. Soviet bureaucrats were even suggested to stop the production of
the shortwave receivers, however it was turned down by the producers. At the start of the sixties Latvian industrial companies like VEF and Radiotehnika were one of the first to produce
portable affordable transistor radios in USSR. Radio was no more a large cabinet like standing in room corner it could be battery-powered and taken to picnics.

Despite the relative liberalization after the death of Stalin and limitation of repressions the ideological war with west was far from over. Broadcasts from the west continued and it was
forbidden to publicly spoke about the content heard in them. Doing so might result an arrest in Corner house of KGB main headquarters in Riga. It was also no secret that shortwave radio
broadcasts inspired many dissidents and no wonder why many workers in VEF and Radiotehnika became dissidents. Most known of them were Gunrs Astra. On September 3 1953 in town of
Auce locals streamed the Voice of America within local radio broadcasting net. They were later arrested.

During the crisis in Hungary on 1956 people were tuned to BBC World Service and Voice of America. Some young students told they only first learned about Stalins cult of personality from
the Voice of America. In Preii region people gathered in groups to listen to Voice of America. While USSR was reluctant to speak about negative news within the country the US spent an
enormous recourses for anti-communist propaganda. President of US Richard Nixon told that its much more useful to spent one dollar on radio propaganda rather than spend 10 dollars on
another new rocket. Another massive radio propaganda network also broadcasting in Latvian was Radio Free Europe that in its r0ots was a funded by US CIA. It was kept secret until on late
seventies KGB funded leftist magazine uncovered it. After that Radio Free Europe was funded by US State Congress. Soviet Union also had shortwave propaganda station Radio Moscow that
transmitted in various western languages. Shortwave radio jamming in USSR was halted during diplomatic warm-ups on 1963-1968 and 1973-1979 both times restarted because of the Soviet
invasions in Czechoslovakia and Afghanistan.  Because of relative low numbers of English speakers the broadcasts in English were not jammed. This is also one of the reasons why in schools
the English studies were limited.

Radio Free Europe begun its Latvian broadcasts on 1975. KGB foreign branch was tasked to gather information about the Latvian broadcasting staff and their editors and tried to infiltrate
their agents in them. KGB succeeded to find information but failed to send agents to subvert the Latvian editions of VoA and RFE. As the soviet power weakened on seventies people were
less afraid to speak about the things heard on the radios. KGB still tried to punish some people who were too open, often it was included into official accusation that the crime was influence
d by the western radio broadcasts. Last such case was for Rolands Silaraups on 1986 the member of the nationalist Helsinki-86 movement.

On 1987 in the spirit of perestroika the shortwave jamming was fully halted. People now closely followed the VoA and RFE. Some of them heard about the first pro-independence protests
on 1987 in the foreign radios and took action on following ones. On political level most influential were the Voice of America and Radio Free Europe. On cultural level the foreign pop and rock
music heard by youngsters on their Spdola radio receivers also boosted the Latvian cultural life. The banned Latvian movie Four White Shirts included  old conservative party functionary in the
censorship meeting talking about the bad influence on the young generations caused by Spdola radio receivers.

Today the World Wide Web has replaced shortwave radio as propaganda weapon. Voice of America no longer broadcasts in Russian or Latvia. Radio Free Europe however continues to
broadcast in Russian and Belarussian over shortwave, because their local coverage within medium waves were closed by Russian authorities on 2012.  Russia itself has stripped their Voice of
Russia the oldest international radio station from 1920ies when it was called Radio Comintern. But, now the neo-soviet Vladimir Putin regime has begun a crackdown on Internet calling it a
project of the CIA. In such manner it could be possible that if Russia will isolate itself from rest of the world, the shortwave broadcasting to Russia can again became active. There is present
example of China and even more extreme of North Korea where controlled Internet has caused extensive shortwave broadcast targeting towards these countries. In return China and North
Korea use extensive shortwave jammers to limit these broadcasts from US and Europe. Will Russia will return to an old days of shortwave jamming and arresting their listeners we shall see.

Thank you to Maris Goldmanis from https://latvianhistory.com/ for allowing us to use that article.

Now follows the e-QSL card for reception reports received for episode 11. This image will be in the MFSK32 mode.



Sending Pic:332x190;



Thank you for all the reception reports sent to reports@digidx.uk. Many of you have correctly identified the MIDI file sent last week as O Canada the national anthem of Canada, part of
which was used as the interval signal for Radio Canada International. The MIDI file sent the previous week was the interval signal of Voice of Korea.

Richard Langley from Canada but listening on holiday in Florida sent me the O Canada MIDI file originally and commented  Both versions of the Base64-encoded interval signal were perfectly
decoded and turned out to be the O Canada midi file I had sent you a few weeks ago. ;-) Of course, O Canada is the Canadian national anthem and the first few notes of a piano rendition
were used for the Radio Canada International IS. Thanks for including it. Thanks for sending it to me, please send any MIDI files of interval signals to me at reports@digidx.uk and I will try and
include them in DigiDX.

Mark Hirst from Hampshire in the UK listened on 6070kHz via Channel 292 on Monday at 2000 and sent the following suggestion:

VOA Radiogram transmitted data using QR codes, I wondered about sending the QSL card as a data QR code ? As long as it's not too small, the black and white shapes come through OK

Good idea Mark, I will certainly look to give this a go next week to try and include the some of the details on the e-QSL card encoded as a QR code.

Mark also commented - The QSL card image was detected but text legibility was difficult - I wonder if the subtle watermarking of the image is partly to blame. This weeks E-QSL card will be
transmitted with a solid background to see if that makes any different to the text legibility.

Rafael Martnez from Spain also listened to 6070 and commented Decoding of Olivia mode was very good despite the noise! Much better than MFSK32, I used the YB400 receiver tuned on
AM mode and wide filter.. Thanks for tuning in Rafael.



Now DigiDX finishes with the tune of another famous shortwave interval signal. This text is a Base64 encoded MIDI file (not a .ZIP file this week)  which can be converted to to MP3 by going
to http://midi.digidx.uk (and select the Submit option) or go to http://www.motobit.com/util/base64-decoder-encoder.asp choosing to decode the data and export to file, the file can then
be renamed a .MID file and then the MIDI file can be opened in Winamp or a similar software.
