I've said before that most of the error reporting is missing. It needs to flow into the telemetry. There needs to be a review of robustness to make sure it will be reliable in failure scenarios.

Maybe this is already done (Chris should know), but there should be a way to tweak the Rx frequencies to be right 'on the money". The tweaking commands are there as I recall, and it is easy to do the Tx frequency (just watch it on a waterfall). But on Golf, at least, it was much easier just to switch the Rx 5043s to transmit and adjust their frequency using a waterfall too. Then when they are in receive mode, they receive on the same frequency. That code may be there for one of the 5043s, but unless Chris added it, probably not for all. (I say this because we will care more that it be right on if the frequencies are coordinated etc etc.

I have been looking at the tasks that I think we would need to complete if we were to fly with UND in 2025.

For our meeting this Thursday I would like to answer 2 questions:

1. Are there any other tasks that should be on this list?
2. Do we have the manpower/interest is completing these tasks for UND?

Remaining Pacsat tasks as of 4/22/2024

Current Software Tasks: Software for monitor and control of 70cm power amplifier Host IHU telemetry interface Testing

Current Hardware Tasks: 7 components that do not fit layout Redesign power system and add to layout ( Vsys = 5.6v Buss voltages = 5.0v, 3.3v, and 1.2v) Correct I2C connection to temperature sensor Select crystal and add to layout Correct layout for T601 Power plane issues for Power Amp and 5V regulator Test 70cm Power Amp circuit Correct preamp bias issues Test receivers and determine differential vs single ended RX inputs Layout was done for Rev C schematic. Add Rev D changes

Other tasks for a Flight Ready design: Measure power requirements Identify configuration changes for flight Create Interface Control Document
