Carlos improves quality of radiofax decodes

Many thanks to SWLing Post contributor, Carlos Latuff, who writes:

I made some adjustments and now I receive better quality radiofaxes. Since I started receiving radiofaxes in 2021, I had forgotten a fundamental detail.

To tune 1.9kHz lower than the advertised frequency. For example, the frequency of Kyodo News is 16971 kHz. I therefore tune in 16970 kHz. Of course, the fact that I tune in at 4:10 am in Brazil also makes a difference, as the propagation is quite good at that time.

Thank you for sharing that tip with up about moving down 1.9 kHz lower than the broadcast frequency. It certainly works–your decodes a very clean.

Many thanks to SWLing Post contributor and noted political cartoonist, Carlos Latuff, who shares his radio log art of a recent NOAA forecast. Carlos writes:

Recently I have been receiving NOAA’s Pacific high seas forecast via 12579 kHz USB. According to the NOAA schedule these SITOR-B transmissions come from the USCG base in Guam (NRV). But I’m not sure about that, since the signal is very strong to come from so far away. Attached is the illustrated report.

Signal received with XHDATA D-808 receiver and long wire antenna.

All the best,

Latuff

Carlos pulls headlines from Kyodo News radiofax

Many thanks to SWLing Post contributor, Carlos Latuff, who writes:

Kyodo News is a Japanese news agency, the only one in the world that still transmits news via radiofax to Japanese vessels, on shortwave frequency of 16971 kHz USB. The international radiofax transmission standard is 120 lines per minute, but the Kyodo News standard is 60 lines per minute.

However, the retransmission of the bulletin in English is done at a cadence of 120 lpm. I’m using an Android application called HF Weather Fax with which I’m decoding the radio signal coming from Japan and received in Porto Alegre, Brazil. The receiver is the Xhdata D-808 and the antenna is a magnetic loop. The image arrived this morning in Porto Alegre, at 4:10 am local time, quite noisy and with a lot of effort I managed to decipher some headlines.

Many thanks to SWLing Post contributor and noted political cartoonist, Carlos Latuff, who shares his radio log art from two recent reports and a radiofax.

Good morning, Thomas.
My radio activity on August 10, 2023.

Attached are two illustrated listening reports about Typhoon Khanun: one from Okinawa Fishery radio station and the other from KBS World Radio.

Also attached a typhoon warning issued yesterday by South Korean meteorology agency via radiofax at 05h00 UTC and received in Porto Alegre. Signal wasn’t good, therefore image arrived with poor quality. Even though, it’s possible to notice the map of Korea and the path of Typhoon Lan, now a tropical storm.
