I was alerted recently to an unusual APRS report which suggested that there might have been an opening on the 144 MHz band between Brazil and the
Azores, a distance of about 6,728kms.
This is the report from the aprs.fi website for CQ1PBA for the 20th of
April 2022...callsign pkts first heard - IST last heard longest (rx - tx)
PY4CEP-14 7 2022-04-20 20:01:18 2022-04-20 20:59:59 GH60XH - HM77GS 6733.5 km 202°
I know that Automatic Packet Reporting System (APRS) generally uses FM on 144.800 MHz in Europe as a beacon mode but I'm not 100% familiar with the
APRS website and what all the reports mean.
I am putting this report here for others to investigate the data on the
APRS website and they can come up with their own conclusions. Do a search
for CQ1PBA and PY4CEP-14 and see what you think.
I suspect the reports are as a result of some sort of HF Gateway or some
other reason that I don't know about. If it was a real opening on 144 MHz
then Trans-Equatorial Propagation might be a possible reason but again, I
think there is a simpler reason.
