Shortwave Radiogram schedule update



Hello friends,


Last weekend was a success in that our transmission of Japanese text was received and decoded in Japan. Audio of that reception (from an SDR) is available here. You can decode from that audio. It begins with some mostly unsuccessful MFSK32, then on to the much more robust Olivia 64-2000.

There were also many good image decodes, which you can peruse at https://twitter.com/swradiogram

Videos of the Saturday 1600 UTC show are available from radio no koe in Japan (using an SDR in New Zealand), Marco in Italy, and Ralf in Germany; and of the Sunday 2330 transmission from Scott in Ontario. Also available is the audio archive maintained by Mark in the UK, and analysis of the weekend's digital-via-analog broadcasts by Roger in Germany.

This weekend will include some text in Arabic. Be sure to use the UTF-8 character set, which is default in TIVAR and newer versions of Fldigi. Also eight images (two MFSK32 and six MFSK64).

And as it is program 52, that means we have completed one year of Shortwave Radiogram. Shortwave Radiogram is the successor to VOA Radiogram, which began on 2013. Thank you for your support!

Here is the lineup for Shortwave Radiogram, program 52, 15-18 June 2018, in MFSK modes as noted:

 1:35  MFSK32: Program preview
 2:40  Excerpt of Arabic text
 3:52  Restoration of Prague's astronomical clock*
10:40  MFSK64: End of net neutrality in the USA*
16:49  Five images*
26:31  MFSK32: Closing announcements*

* with image(s)

Arnie's look at amateur radio's FT8


Radio Havana Cuba
Dxers Unlimited middle of the week edition for Tuesday 12 June 2018
By Arnie Coro radio amateur CO2KK


Yes amigos as always you are most welcome to another edition of Dxers Unlimited, our station's twice weekly radio hobby program... This is the middle of the week program that goes on the air just after the half hour news bulletin. I am Arnaldo, Arnie, Coro radio amateur CO2KK , and here is item one of the show.... the ever popular section of Dxers Unlimited.... ASK ARNIE

The question came from long time ... listener Edward from Vancouver, Canada sent an email telling me of the nice results he has achieved with his 14 meters long  version of the TTFD antenna... Edward says reception from 5 to 30 megaHertz is excellent, and he has already tested the antenna for transmitting on the 30 and 20 meters band, making comparative tests with half wave dipoles for both bands. Arnie, he writes, your version of the TTFD using the 800 ohms homebrew terminating resistor and a 9 to one balun feeding into 75 ohms coaxial cable works well on both 30 and 20 meters, and is usable for daytime short range contacts on 40 meters too... Edward added that he picks up our 6100 kilohertz transmission to the Pacific Coast of North America just like a local FM station, something that made our RHC's engineer, Argelio Rodriguez a very happy person indeed.

And now a  Dxers Unlimited special report about amateur radio The great FT8 debate: A  new automatic linking digital communications mode that goes by the short name of FT8 has become extremely popular on the amateur bands since last year ... As a matter of fact FT8 contacts have made possible never before seen achievements on the short wave amateur bands...

Opinions about the use of the FT8 communications protocol are been published at many amateur radio world wide web sites....  You will soon here what your friend, Arnie Coro,  CO2KK  thinks about it...but before here is how  British radio amateur Mark, callsign M Zero B LF voiced his points of view that I am now quoting here: Mark says in his lengthy essay: I’ve been pondering for a while about whether or not I should add my own opinions to the polemic about FT8, the now year-old digital mode that has taken the ham radio world by storm. A few things recently have convinced me that I should, which I’ll go into a little later in this short essay.

First off, a step back: What is FT8? It’s the latest in a line of digital modes developed by Joe Taylor K1JT, that permit two-way radio contacts to be made with incredibly weak signals, that are often below the noise floor.

Until last year, most of the modes in this family were used for specialised purposes such as EME (bouncing radio signals off the moon) or meteor scatter. This meant that they were adopted by a small subset of radio amateurs for their specific purpose.

About a year ago, FT8 came onto the scene.AND HERE IS THE MAIN DIFFERENCE --- Mark explains that  Its main difference over the other modes in the lineage is the speed of an ‘over’: reduced from for example 50 seconds in JT65 to just 15 seconds. This made it much more suitable for generalized use, and very quickly FT8 was adopted for general contacts.

A post by Clublog author Michael G7VJR in January this year shows how exponential the popularity of this mode was in the second-half of 2017; a trend which seems to have continued. I was certainly part of this band-wagon of FT8 fans. I logged my first FT8 contact on 16th July 2017, and to date I’ve made 118 QSOs using the mode from home.

Some people have tried to argue that FT8 isn’t amateur radio. I disagree. For a hobby founded on experimentation, technical challenge and self-training in all forms of communication, FT8 is the very essence of what amateur radio advances should look like. It’s very clever technology with some seriously complex maths behind it, that represents (technically) a significant step forward from what we had before. Si amigos, I will like to read again that part of Mark's posting: listen carefully

Some people have tried to argue that FT8 isn’t amateur radio. I disagree. For a hobby founded on experimentation, technical challenge and self-training in all forms of communication, FT8 is the very essence of what amateur radio advances should look like. It’s very clever technology with some seriously complex maths behind it, that represents (technically) a significant step forward from what we had before.

Mark adds:
I also believe that FT8 has its place in our shacks. One of the biggest threats we have to the hobby is that, particularly in sub-urban environments, noise floors can be very high from consumer electronics. Furthermore, in a globalized world, national regulators appear generally impotent to enforce the regulations that are supposed to avoid pollution of the radio spectrum from poorly-designed equipment. This was one of the reasons for my speedy adoption of FT8. Frankly, from my location on the outskirts of Cambridge, I wouldn’t be able to work as far without the support of the weak-signal error correction that’s inherent in the mode.

This is all the more important during solar minimum, which I suspect plays a large part in the quick spread of FT8. For the next few years, the stage of the sunspot cycle means that radio wave propagation will be hard, especially on higher HF  bands. Having a mode available which allows low signal-to-noise ratio contacts is certainly a help to communication on those bands, which would otherwise be ‘dead’. And then, here is what I consider to be a very well thought analysis about one essential advantage of using the FT8 digital mode. Mark says: The other fantastic thing about FT8 is that it brings, for the first time, objective signal reports to the hobby. We all know that ’59’ is a nonsense, but in the more ‘manual’ modes, we don’t have anything better.

Using actual, genuine, signal-to-noise measurements for signal reports allows more meaningful comparisons of equipment, antenna performance and propagation research.

Si amigos, yes my friends , oui mes amis... Here is more to add fuel to the controversy about the now extensive and intensive use of the FT8 digital mode as expressed by Mark M0 Bravo Lima Fox....
Mark continues by writing: However, in recent months a few things have happened, which started to quell my enthusiasm for the mode.

First was one day when I was working from home, doing my day-job. Since the computer was on anyway, I left FT8 running, periodically clicking the ‘Log QSO’ button when I saw it on the screen. Operating like this, I managed to make about 25 QSOs during the day without even realising it. None of those contacts were memorable. The computer made them for me, while I worked on other things. Moreover, the nature of the FT8 exchange (the facts that you have only 13 characters per over, and that changing the text of an over from the defaults can confuse the other operator) means that I felt no connection with those people at all.

FINALLY, THERE IS NOW A VERY IMPORTANT POINT OF VIEW ABOUT THE EXTENSIVE WORLDWIDE USE OF THE FT8 MODE...Similarly, the focus in the community on monitoring the main FT8 spot frequency on each band, means that other contacts seem to be being missed. I know lots of people are pouring over the stats to see whether FT8 activity is ‘new’ activity, or to the detriment of other modes.

In an upcoming edition of Dxers Unlimited, I will continue dealing with the controversial FT8 digital communications mode... Now  please listen carefully  to my preliminary point of view.... As a soon to be 59 years on the air amateur radio operator.... I have learned to give a very high value to the human aspects of our wonderful hobby.... and sincerely , I believe that using FT8 does nothing to promote new friendships among the world's amateur radio operators...machines do not make friends with people !!!!

Amigos , I wrote the first part of the script of this show Sunday morning... while monitoring the 6 meters amateur band searching for possible sporadic E skip signals that could make possible skywave contacts during the ARRL June VHFcontest.... At just twelve noon local time ,  16 00 UTC , nothing heard in the form of CW or SSB stations, and , as expected, on 50313 the FT8 parking spot, several signals where picked up by Jose CO2XN who happens to have the best 6 meters station in Havana,
with his 7 elements YAGI antenna...

Your opinions about the use of the FT8 digital mode are most welcome.... send them to inforhc at enet dot cu and also to arnie@rhc.cu amigos

DXers Unlimited - June 10 edition



Radio Havana Cuba
Dxers Unlimited weekend edition for Sunday 10 June 2018 By  Arnie Coro radio amateur CO2KK

Hola amigos radioaficionados all around the world and orbiting planet Earth aboard the International Space Station where the crew members continue to enjoy sending back to Earth slow scan television signals on the 145.800 frequency with excellent results...

Yes amigos radio amateurs are in space and having a good time during the short periods when they can take a break from the demanding duties aboard the very complex space ship... I am Arnaldo, Arnie, Coro radio amateur CO2KK , your host here at the weekend edition of Dxers Unlimited, the one and only radio hobby show that receives and answers all your questions related to the wonderful way you and enjoy our free time...playing with our radio and their many accessories

Item two:
The summer sporadic E layer season, of the northern hemisphere is now in progress... I am now insisting on the short term forecast for the 2018 sporadic E season. I did sent a quick reply to a listener that wanted to know what was the forecast for this year's E skip season... Here is what I wrote to amigo Richard , in Florida, USA

Here is my forecast... expect above average 6 meters Sporadic E summer season for 2018...
There  seems to be an ever growing criteria among 6 meters band Dxers that sees a clear inverse correlation between periods of very low solar activity and the occurrence of sporadic E events.
Will be looking for you with my six meters QRP Five Watts and my simple sloping dipole antenna...
Yes I have worked many 6 meters stations using a 55 inches whip antenna with one ground radial 57 inches horizontal ground radial !!!

Now I will compile all the observations about the spring and summer 2018 sporadic E season and we will find out if my forecast was accurate or not...with results available by September of this year of minimum solar activity. During the year 2016  several good transatlantic band openings on six meters band were enjoyed by operators all along the East Coast of Canada and the USA and they were able to make many nice contacts using typical stations running not more than one hundred watts on single side band and a three four or five elements YAGI... Caribbean stations also enjoyed the openings to Europe and to North America too.

For TV Dxers in the USA this season brought the possibility of picking up many Mexican , Central American and Cuban analog TV stations that are still on the air using the NTSC-M 525 lines resolution transmission standard now in the process of being phased out in favor of digital TV over the air broadcasts.

Item three
Your attention please homebrewers that can read circuit diagrams, identify electronic parts and know how to solder... for those of you … It is perfectly possible to build a very simple amateur radio CW radiotelegraphy transmitter with a minimum of parts, and yet achieve reliable results... It does need very careful construction to make the home brew self oscillating Hartley rig stable enough to be able to use it on the amateur bands. Results so far show that on the 160, 80 and 40 meters bands, using just ten, yes, just ten parts, the rig built around a single vacuum tube may be used on the air with excellent results.

Now let me tell you that when I sent the original schematic of the Hartley single vacuum tube power oscillator to a friend of mine that is a senior telecommunications engineer at Havana's famous CUJAE technical university,  he came back immediately to tell me not to dare put that transmitter on the air.... because he said it will drift badly and produce an awful keying CW note... Then, my reply went back with an mp3 file of the sound of the Hartley power oscillator on the air.... a nice clean, stable signal free of frequency drift or keying chirp...


Courtesy of my long time  Italian friend Cristiano Greggio who has spend a lot of time experimenting with simple vacuum tubes receiving and transmitting equipment that are producing really amazing results.

Yes amigos you are listening to Radio Havana Cuba and here is more about low cost , simple equipment for enjoying the radio hobby without having to apply for bankruptcy....

There is no doubt that professional radio receivers designed and built by the German firm Rohde and Schwartz are among the best in the world. Then you may want to know that a very simple REGENERODYNE  home built vacuum tubes receiver is matching and even exceeding the sensitivity of one of the classic Rhode and SchwartZ HF radios...

Amazing as it may sound, it is fully documented with many actual comparative tests using the same antenna switched between the two radios... This information also comes from amigo Christiano Greggio of Italy... he tells us that using an ECH81 or ECH83 triode heptode tube frequency conversion stage, feeding another identical tube uses as regenerative detector and first audio amplifier stage, when operating on the 40 meters amateur band, reception is very good, making possible to detect very weak signals that are buried into the front end noise of the professional receiver.

My version of that radio built using Russian vaccum tubes is now in the works with the added feature of  a front end dual tuned bandpass input filter and a single pentode radio frequency amplifier stage just to compensate for the signal lost in the filter.

And my audio module will also contemplate the use of two audio filters... I have now almost all the parts needed for the project,  and ready to start testing each component one by one before the parts entry into the assembly line, something that I always do before starting to place the parts into circuit boards or chassis point to point wiring, in order to avoid the problems associated with using a defective part on a new radio.

Believe me, testing each and every part before assembly is a really sound practice...  Also follow my advice and never start the building process before you have at hand all the parts required for the project...I have two projects left at a standstill years ago when a missing part was never found...

And now talking about simple receivers and transmitters let me add that my favorite band for them to operate is 40 meters, because during the daytime it provides very nice local and semi-local coverage and at night it changes into a wonderful band for making DX contacts...40 meters will continue to be a very reliable band for night time Dxing for the next two years amigos.... that is why installing a nice seven megahertz antenna is also a worthwhile project, especially if you can add to it wire elements for the 30 and 20 meters bands too....

Now  a short form prediction of the solar flux levels for the near term, it will stand at near rock bottom values not to exceed 75 units for the next week or so.

The sun continues to show no sunspots for the past several days and solar cycle 24 continues its slow downward trend amigos !

Send your signal reports and comments to inforohc@enet.cu and via air mail to: Arnie Coro Radio Havana Cuba, Havana Cuba...

See you all at the middle of the week edition of Dxers Unlimited just after our half hour news bulletin ...

Highlights of Solar and Geomagnetic Activity 04 - 10 June 2018

Solar activity was mostly at very low levels with an isolated  C-class flare observed at 06/1100 UTC from Region 2712 (N15, L=176, class/area Csi/080 on 28 May) from just beyond the West limb. The
solar disk was spotless from 06-10 Jun. No Earth-directed coronal mass ejections (CMEs) were observed during the reporting period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels throughout the period with a maximum flux of 19,491 pfu  observed at 06/1705 UTC.

Geomagnetic field activity ranged from quiet to active levels over the period. Solar wind speed was in decline from a negative polarity coronal hole high speed stream (CH HSS) on 04-05 Jun with solar wind speeds declining from approximately 630 km/s to near 450 km/s while total field ranged from 2 nT to 9 nT. The geomagnetic field was at quiet levels on 04-05 Jun. By midday on 06 Jun, an enhancement in total field was observed reaching a maximum of 11 nT at 07/0635 UTC.

The Bz component reached a maximum of -8 nT at 06/1820 UTC. The geomagnetic field responded with quiet to active levels on 06 Jun and quiet to unsettled levels on 07 Jun. By 08 Jun and through the rest of the period, solar wind speeds were at nominal levels with solar wind speeds at 400 km/s or less and total field at 5 nT or less. Quiet conditions were observed on 08-10 Jun.

Forecast of Solar and Geomagnetic Activity 11 June - 07 July 2018

Solar activity is expected to be at very low levels with a slight chance for isolated C-class flares from 11 Jun-01 Jul with the return of old Regions 2711 (N06, L=288) and 2712 (N15, L=176) to the
visible disk.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 11 Jun and again from 28 Jun-07 Jul due to CH HSS influence.

Geomagnetic field activity is expected to be at unsettled levels on 12-14 Jun and 19 Jun due to weak CH HSS effects. Unsettled to active levels are expected on 27-30 Jun with G1 (Minor) geomagnetic storm levels likely on 28-29 Jun due to recurrent CH HSS effects.

Shortwave Radiogram schedules

Hello friends,


Last week's broadcast Monday at 0800-0830 UTC was not transmitted on 7730 kHz. WRMI informs me that the issue has been resolved. This frequency is good to Australia and New Zealand, among other places. At 0800 UTC, WRMI's other frequency, 5850 kHz, was well heard in much of North America, and I even received it using an SDR in Japan. The signal, not surprisingly, was weak. So, hoping that 5850 reaches Japan again this weekend, the show will start with some Japanese text in the Olivia 64-2000 mode.

Among videos of last weekend's broadcast are this one by COMMS partisan, Sunday 2330 UTC, with narration explaining the concept. And an excerpt by radio no koe, using a receiver in Qatar (Saturday 1625 UTC). For the entire half hour, see the videos by Ralf in Gemany (Saturday 1600 UTC) and Scott in Ontario (Sunday 2330 UTC). For audio, visit Mark Hirst's archive.

Here is the lineup for Shortwave Radiogram, program 51, 8-11 June 2018, in modes as noted:

 1:31  MFSK32: Program preview  
 2:43  Olivia 64-2000: Japanese text
 9:00  MFSK32: More passenger trains in Slovakia*
13:20  MFSK64: Juno mission to Jupiter gets extension*
18:00  Five images - tornado, birds and flowers*
28:28  MFSK32: Closing announcements
