So where is the amateur operator courtesy on Amateur Satellite ?
Apologize I'm going to vent-off after this morning's (23 Aug, 01:20 UTC) SSTV exercise on IO-86 satellite
First is a background of IO-86, which is the secondary (amateur radio) payload on Indonesia's LAPAN A2/ORARI that was completely designed by AMSAT-ID team with LAPAN's satellite design team. This amateur payload was designed primarily to assist in disaster communication while regular communication lines are off utilizing only handheld radio (HT) with a simple beam antenna, thus the payload has a high-gain receiver antenna and relatively high power (5W) transmitter. IO-86 has performed flawlessly in several emergency communication (such as earthquake in Lombok, 2017, tsunami in Palu 2018 and flashflood in Masamba, 2020, all using HT). To ensure availability of amateur radio operators ready for future emergency communication, AMSAT-ID has been conducting various communication exercises thru IO-86. On top of Voice and APRS communication, IO-86 also supports SSTV mode where one can transmit pictures of the emergency location, thru the voice FM repeater.
So this morning, to mimic an immediate request for SSTV, part of Emergency Readiness component of IO-86, I transmit on IO-86 requesting all stations to standby, several times, to clear the frequency for SSTV transmission. But a high-power station, from a neighboring country, kept overpowering IO-86 with his call for a QSO. Repeated requests to standby are just kept being ignored.
So, where is the courtesy of amateur operators of a standby request? To stop transmitting and monitor the frequency as maybe there is another activity being conducted.
I'll share the lesson learns from the SSTV thru IO-86 exercise in another email
