I'd be interested to see the design /code for SC rig with the AX5043
chip. I have similar goals of implementing various radios (balloons,
satellite, etc.) using this device (the PSK and HDLC features make it
enticing). Are there plans for posting any of the code or schematics
for this? I know Jonathan Brandenburg has done a lot in this area
already (https://github.com/BrandenburgTech/DigitalTxRxRPi), but more
public code sounds good to me!
My biggest concern at the moment with these chips is that individuals
are not available on Mouser or Digikey, Mouser has reels of 3000
available and the product is marked EOL. Other documentation suggest
this is just a 'hiccup' as they transition from one manufacturing house
to another, but its hard to get started playing with these if 1) i can't
get my hands on small quantities and 2) not confident yet that they will
be readily available in small quantities long term...............I
hunted around and couldn't find a similar device with all the same
features.......so I'm hoping the new stuff shows up on Mouser/Digikey
soon.....
