First of all an apology for the title to the vast majority of users which follow the rules on using the QO-100 transponders. Your activity both as operators but also as hamradio experimenters, builders and ambassadors for our hobby is our fuel to continue working on future amateur radio satellites.
The following lines are addressed to the few individuals (YOU) which constantly ignore the rules set up by AMSAT-DL. I am writing 'ignoring' on purpose. Not 'bending' or 'challenging' but 'ignoring'. After more than half a year the rules should be obvious to all users. Working QO-100 is by no means an easy feat and we can certainly rule out 'accidental' transmissions to the satellite. Still not a single week passes without me observing your mindless and selfish behavior on the transponder: transmitting outside its authorized frequency limits, exceeding the defined power levels limits and using excessive bandwidth (to mention only a few). Although I will not play the 'shame and blame' game (others are much better at this and I thank those for doing it for me!) you should note that your behavior is gravely endangering the future of amateur radio satellites and our status as 'hitchhiker-payload' in particular! The rules are in place for very good reasons and while you might not agree with them: here they are. I cannot and will not justify them individually (last but not least due to NDA restrictions) and I do not think AMSAT-DL has to. QO-100 is a very generous gift by the satellite operator and a few very supportive persons and we should treat this gift with decency and care. It is NOT a service and you have NO rights on using it. If you do not agree with the rules, I would recommend you to go somewhere else and let others enjoy the gift offered to us. As a reminder, amateur radio via satellites is a low-power mode and there is absolutely no justification to use more power than required to use the transponder. Your constant misbehavior sheds a very bad light on the amateur radio community. It will eventually lead to temporary or permanent stop of QO-100 operations and subsequently kill any future efforts to get similar payloads flying on future commercial satellites. Not only this is asocial behavior against all well behaving hamradio operators but it is a punch in the face of all volunteers of the Phase-4A project which have dedicated considerable time of their lives in the past years to make this happen.
Thank you for that.
