@swradiogram.bsky.social www.rhci-online.net/radiogram/SW... QAM4: O=3 ok QAM16: O=4 ok QAM64: O=5 at least... I think, 7z corresponds roughly to the internal lz-html compression in EasyDRF.

KBC Digital - today without Peter John's involvement: www.dropbox.com/scl/fi/dwz91...

@swradiogram.bsky.social KBC data from this weekend. The first part from friday, then there was a sudden modulation failure on 15770 kHz. The second part (SSTV) then from this night. www.dropbox.com/scl/fi/vxhqn...

@swradiogram.bsky.social Analysis of today's KBC data: www.dropbox.com/scl/fi/oyezp...

@swradiogram.bsky.social And here is another picture regarding the transferred and decoded "RNEI-RRR16.html": www.dropbox.com/scl/fi/06f4z...

@swradiogram.bsky.social Here is a collage with further broadcast dates of a great music and data show: www.dropbox.com/scl/fi/u86o5...

@swradiogram.bsky.social KBC data from this morning: 2 x PD50 + 1 x BW12 = Σ net 112 seconds =>> gross 120 seconds www.dropbox.com/scl/fi/pu33a...

@swradiogram.bsky.social The QRM in the MFSK pic clearly originates from the SSTV sync-signals at 1200 Hz. Subsequent AF filtering has no effect. However, it can help if you completely mute the AF range of the SSTV tracks below 1100 Hz BEFORE mixup the data tracks. www.dropbox.com/scl/fi/ch30s...

@swradiogram.bsky.social KBC data from today before noon on the 15770 kHz/WRMI. Artificial images of radio friends, without pets. www.dropbox.com/scl/fi/fil75...

@swradiogram.bsky.social Sound processing.... www.dropbox.com/scl/fi/ibgb5...

@swradiogram.bsky.social KBC-data-collage regarding yesterday. The interference lines in the MFSK-32 image @512 Hz most probably originate from a 50 Hz source, since 20 ms spacing. In the *.zip the single data components, separated with a spectrum editor. www.dropbox.com/scl/fi/hy16v...

@swradiogram.bsky.social KBC data from March 21, 2025, via WRMI 15770 kHz, starting at 1130z. For DX headlines, the usual modes: 2x PD50 + MFSK32 txt for the image description. www.dropbox.com/scl/fi/o4bko...

@swradiogram.bsky.social KBC data from Friday noon, 15770 kHz WRMI: www.dropbox.com/scl/fi/utpdc...

@swradiogram.bsky.social GUERO radiogram from last thursday via WRMI. In contrast to the version sent out via ch292 two weeks ago, this time with an additional image in MFSK-64, but at +1590 Hz AF shift. Probably a production error, not intentional. www.dropbox.com/scl/fi/f4otl...

@swradiogram.bsky.social The current Cult of Show with a data track in the background. However,the selected and attenuated digital mode clashes badly with the music and the error devil had an easy time. The robustness of OL32-1K was probably vastly overestimated here. www.dropbox.com/scl/fi/ct8cm...

@swradiogram.bsky.social Decoded data from an unattended recording from RRR-14. I will listen to the obviously interesting musical mix in the next few days, at a more pleasant European local time..... ;-) www.dropbox.com/scl/fi/4hly5... www.dropbox.com/scl/fi/zufid...

@swradiogram.bsky.social KBC data from today. DX headlines once again with multitrack experiments - no problems with Fldigi. Here is a collage to understand the acoustic mix: www.dropbox.com/scl/fi/v9aec...

@swradiogram.bsky.social 2x Radio Carpathia RC23 1'st on Thursday on 5850 kHz together with DK Radio EP12, both with data. Then on Saturday RC23 (without data) on 9670 kHz together with guest show from Guero +data/playlist. See collage, for a better understanding: www.dropbox.com/scl/fi/x27le...

@swradiogram.bsky.social KBC data from today, the 15770 kHz were on air again. The electrical company had obviously done a good job. www.dropbox.com/scl/fi/vhte4...

@swradiogram.bsky.social KBC data from the 15770 kHz WRMI friday noon, zulu time. Topic of the current DX headlines: Nederlands Openlucht Museum Arnhem (dutch open air museum. www.dropbox.com/scl/fi/jghm3...

@swradiogram.bsky.social An additional orbital echo (around the earth) on 15770 kHz with a delay of 138 ms could be heard on an SDR in Vermont. The cyclic synchronization pulse of the PD50 mode proved to be optimal for visual evaluation. www.dropbox.com/scl/fi/t8j3h...

@swradiogram.bsky.social KBC data from today on 7780 kHz - received in New Zealand. Image structure diffuse by multihop-multipath. Despite this, MFSK64 SNR still at 6 db. www.dropbox.com/scl/fi/g461s...

@swradiogram.bsky.social KBC data from today at noon, Zulu time. Hopefully Peter John and his PC equipment will feel better soon. www.dropbox.com/scl/fi/oibkz...

@swradiogram.bsky.social KBC data from this morning on 7780 kHz. I now wonder if there is a connection between the sunspot minima and the years in which the icy “Elfstedentocht” (Eleven Cities Tour) could take place? I asked chatGPT for the years in question. www.dropbox.com/scl/fi/btoza...

@swradiogram.bsky.social KBC data from this morning. 2xPD50 and 1 MFSK32 track on 512Hz. In foccus of Peter John's SSTV images: Oliebollen - literally “oil balls”. This is flour/yeast pastry - baked in hot oil. From a German point of view probably a kind of doughnut. www.dropbox.com/scl/fi/a5m8e...

@swradiogram.bsky.social KBC data from yesterday noon. If you put a 300 Hz wide notch at -2 kHz on the Russian T-600 modem, then you can also use most of the LSB data from the 15770 kHz - and don't have to limit yourself to the USB side. www.dropbox.com/scl/fi/k8wsl...

@swradiogram.bsky.social Decoding from last Wednesday of Pop Shop Radio from British Columbia, Canada. It was a broadcast as part of RNEI's 4 hour Yule Marathon via Woofferton on December 25, 2024. The collage also contains information about the station. www.dropbox.com/scl/fi/u1hhh...

@swradiogram.bsky.social Decoding from last Monday from Radio Catface Int'l. It was just a repeat of an older show #30 (“#35” would be current) - but possibly worth mentioning given two additional data tracks. The collage also contains information about the station. www.dropbox.com/scl/fi/awbgl...

@swradiogram.bsky.social KBC data from Saturday morning on 7780 kHz. The audio data of the MFSK32 pic was cut off at the end in favor of the WF texture and the THOR track was forgotten. But despite the lack of a description, it is possible to recognize the animals. 😺 www.dropbox.com/scl/fi/b5q2r...

@swradiogram.bsky.social Apparently the Giant Jukebox (KBC) has been running since 0100z on 891 kHz medium wave via Huissen / NL. Digital data slots can therefore be expected around 0130z & 0148z.

@swradiogram.bsky.social KBC data from today. Peter John's audio editor for waterfall texts doesn't seem to be much good, or his settings are just not up to scratch. www.dropbox.com/scl/fi/vf2kx...

@swradiogram.bsky.social KBC data from today: including 3 pictures from Amersfoort, Peter John's home town. www.dropbox.com/scl/fi/xzxqw...

@swradiogram.bsky.social @mrdoublek.bsky.social A look back to last Thursday on 5850 kHz. 30 minutes DK Radio episode 10 with the closing playlist in MFSK-64: dropbox.com/scl/fi/ww3xp...

@swradiogram.bsky.social Compact collage of RRR-11, a very good music program with a mixture of rather unknown, underrated artists and a few classics. The synchronized online playlist and the data embedded in the audio are unique. rhci-online.net/html/RNEI-RR... (<5 kb lz/html data !!!)
