Hey @vk5qi , the radio that we have (Spacequest TRX-U) is delivered with a frequency set. There is a command available enabling a force-feed of the transceiver registers (enabling a frequency change), but there are a few issues with changing our frequency now:
- the command is not persistent through a radio power cycle, and we have observed many spacecraft resets on orbit for our other cubesats on orbit. To have this command issued automatically on a spacecraft reboot would require a flight software change (program management is opposed to this)
- the command is not recommended for anything but diagnostics or experiments, which I would argue being on-orbit doesn’t qualify as one of those two use cases
- the issue with the power board and intended flight radio was discovered somewhat late in the game. At this point the spacecraft is being delivered to the launch provider on Friday and no further testing is possible.
This gives me no joy, especially when we are already out of alignment with the amateur community with our AX.25 header issues. We have someone working on contacting the IARU to have a discussion with them, and hopefully we can come to an understanding before we launch.
