I produced this weekend's VOA Radiogram yesterday (Thursday), during the administration of Barack Obama. It will be broadcast during the administration of Donald Trump.
The show will include one item about past inaugurations, and the final image will show the National Mall, site of the inauguration, with the VOA headquarters also in the picture.
One science news item this weekend will be in Olivia 64-2000, which may be helpful if reception is poor.
Mid-winter propagation continues to provide challenges and opportunities. Some listeners in northern Europe heard and decoded last weekend's broadcast Saturday 0930-1000 UTC on 5865 kHz. And the Sunday 1930-2000 UTC broadcast on 15670 kHz, lately difficult to hear in Europe (the nominal target), was received last weekend in New Zealand. (See images below.)
A few operating notes:
- For best Olivia 64-2000 performance, turn Fldigi's squelch (SQL) off.
- The RSID at 1500 Hz sometimes mixes with the transmitter hum, most noticeable at 360 Hz, to move your receive audio frequency down to 1140 Hz, resulting in no decode. To prevent this, in Fldigi: Configure > IDs > RsID > unselect Searches passband. Your center audio frequency will wander no more than +/- 200 Hz.
- Fldigi automatically saves your decoded MFSK images as png files in the folder \fldigi.files\images\ (in Windows; folder names might be different with other operating systems). You can attach those png files with your reception report.
- The VOA Radiogram Twitter account @VOARadiogram is especially active before, during, and after the broadcasts. You don't need a Twitter account: just go to https://twitter.com/voaradiogram and refresh it occasionally.
Please send reception reports to firstname.lastname@example.org
