New Twitter account made especially for Slow Scan Radio: @SlowScanRadio
I am sorry to say that because of some minor health problems, I had to cancel this week’s and next week’s show.
Nothing serious I will be back in two weeks!
Especially for the (Dutch) Daily Minutes broadcast and the other English broadcasts now there is open sourc and non-commercial social media. Daily Minutes and Slow Scan Radio now have an own social media server within the Mastodon network, which let’s it function on many other servers world wide. And this all works without you being spied on!

At the beginning of Slow Scan Radio, some nine weeks ago, I said I would try to get our show to WRMI every 4 weeks, so that it could also be received in the USA. Most probably a signal from there with 100 kW can also be received in Europa.
After that, I received several requests to make that a weekly event. The only way for me to accomplish that is with the help of some sponsoring by our listeners. So that is what I am going to humbly ask you for here.
If you want to take part in this and support the effort for a time slot for the show at the transmitters of WRMI each week, you can donate to enable us to bring the show on the air at WRMI that way. This can be done by PayPal at our regular mail address email@example.com. A small amount will be ok, especially if you would want to repeat that for some time at a later instance.
I have reserved a starting amount for broadcasting the show 6 times myself to begin with. So if I am able to have enough people supporting this, we can start broadcasting from Florida each week at least for several weeks and hopefully much longer. If I don’t succeed in getting together the amount for a weekly broadcast, then I will stay with the original plan of broadcasting from Florida once every four weeks at least for several months.
Beware, Slow Scan Radio will be at 1730 UTC tonight. Let’s see how that works for propagation. If you have any reports about differences from other weeks, please send them to firstname.lastname@example.org
We are planning to do a broadcast of the show from the location of WRMI near Miami, at least every four weeks.
For that we are considering opening some kind of listener sponsorship to be able to do such a broadcast from Miami every week instead of once every four weeks.
One possibility we are considering at the moment is to open the possibility of a patronship via www.patreon.com to enable us to do this.
In addition to that we are open to company’s sponsoring such shows. If you are interested, please let us know on our mail addres email@example.com
You can also send your phone number so we can call you back.
Receiving data is best using only one of the sidebands of the AM signal. This can be done by using a narrow AM filter (normal is 6 to 9 kHz, use 3 to 4 kHz instead) and tuning to the carrier and one of the side bands. Alternatively you can use USB or LSB.
Receiving both sidebands can be a problem if propagation distorts both sidebands differently, which is often the case. Using only one sideband prevents this, giving a better reception.
Using a synchronised AM detector for digital signals most often isn’t an improvement, because both sidebands are used then too.
Synchronised AM can improve music quality though. With very deep QSB often the carrier dissapears partly or competely. This can cause distortion similar to receiving SSB on an AM receiver, which can be quite catastrophic for your music experience.
A synchronised AM detector introduces it’s own carrier, which always has the appropriate level, keeping it in sync with the original carrier, even if it dissapears for a short while, hence improving audio quality very much during those instances.
Slow Scan Radio brings you several SSTV images and several minutes of data via short wave radio in AM. We are on 6070 kHz via Channel 292 each Wednesday, 1830 UTC, which is 2030 Central European Summertime.
Next show we will start with a digital overview of which SSTV modes and data types we will bring, so you will know those details beforehand in case you want to do those settings manually. We will transmit that list in MFSK64 and most probably also in PSK63R with 32 carriers.
Response to the first broadcast by the way was quite overwhelming. Everyone thanks for mailing your reports and comments on the show! It is very much appreciated!! (Mail Address you can find on the right side of this page, almost at the start of the page.)
