I hate when that happens! Good luck tracking it down!

@swradiogram.bsky.social Great results in northern Florida, USA on the Thursday/Friday broadcast over WRMI! 0030-0100 UTC, 9265 kHz.

Spring is springing all around us! Warm weather is on the way.

Nice!

@swradiogram.bsky.social Some of Wednesday's results from northern Florida, USA; 1330-1400 UTC, 15770 kHz. Ten images decoded out of the eleven transmitted.
Text decoding in MFSK64 was very good, about 95 % accurate.
All RxIDs worked.
Using active loop antenna with Airspy HF+ and SDR# software.

I haven't noticed any of the artifacts in images decoded from Kim's 5850 kHz broadcasts. FLDigi didn't catch the MFSK64 RxID from last night's SwRg at 0800z. I wouldn't say that's the usual case; propagation plays tricks. BTW, I hardly ever miss the RxID to MFSK32.

@popshopradio.bsky.social Good signal level here in n. Florida last night on 5950 kHz! Was able to get this great decode over-the-air.
"Jazzman" such a great Carol King song!!

When WRMI uses new audio processor the RxID to MFSK64 is unreliable. Kim Elliott mentioned it his reminder to Sunday b'cast on 9955 kHz.
It regularly happens on 5950 kHz, also Friday's on 15770 kHz. You can see the effects in MFSK images.
Cindy Wilson from KBC's Sunday on 15770 on SDR in MA/CT.

@swradiogram.bsky.social Final group.

@swradiogram.bsky.social First four images from northern Florida, USA reception of Sunday's broadcast on 9955 kHz.

As predicted RxID to MFSK64 did not work. Backup recording to the rescue...

Here's my over-the-air copy from FL.

As we march into March here are my decoded images from last night's broadcast over WINB here in northern Florida, USA.

Using a wire antenna this time and testing a homebrew common mode choke to cut HF EMI based on: youtu.be/dcXq6u64HXg?...

@swradiogram.bsky.social Images 2 and 1 from the broadcast as received in northern Florida, USA.

@swradiogram.bsky.social The middle of the images section appears to have encountered some signal fades or noise bursts...

@swradiogram.bsky.social Here are the final four images decoded in northern Florida, USA from the Thursday/Friday broadcast, 0030-0100 UTC, 9265 kHz.
We'll work backwards from here...

@popshopradio.bsky.social My decoded image from Sunday night's broadcast over WRMI on 5950 kHz.
I was using a KiwiSDR in Missouri. I forgot to record the show. I can check on the PopShop website to catch up.

@swradiogram.bsky.social Reporting good reception Wednesday on 15770 kHz, 1330-1400 UTC in northern Florida, USA.
Barely any multipath echo in WRMI's signal.
Text decoding was very good. MFSK64 had only this one error.
Using active loop antenna with Airspy HF+ and SDR#

@swradiogram.bsky.social Four representative images from reception in northern Florida, USA of Sunday/Monday overnight broadcast on 5850 kHz.
Missed RxID into MFSK64 during the show; recovered using a backup recording.

@swradiogram.bsky.social Final two images.

@swradiogram.bsky.social Images from last night's WINB broadcast, 0330-0400 UTC on 9265 kHz as received in northern Florida, USA.
Getting good results with this DIY version of a LZ1AQ loop amplifier. Using CM chokes at each end of coax run.
Airspy HF+ and SDR# software.

Could it automate some tasks around the shack, like "every Monday at 07450 UTC start SDR#, tune to 5850 kHz, open FLDigi, open Audacity and record Shortwave Radiogram from 0800-0830 UTC and save the file as an MP3?

@swradiogram.bsky.social I received this week's Birthday Radiogram of Rhiannon Giddens while listening to Eric's "The Giant Jukebox" Friday 11a-12p UTC on 15770 kHz using a KiwiSDR in French Alps.

@swradiogram.bsky.social Images decoded in northern Florida, USA on Wednesday during broadcast on 15770 kHz, 1330-1400 UTC.
I'm hearing multipath in the vocal portions of the program following SwRg.
Tuned in a little late and missed much of the MFSK64 text. Closing text in MFSK32 was 100% accurate.
