Machined and turned a little brass piece to mount the Tx to the PCB disc, for the VTS.
It was held in place on the PCB using a titanium bike spoke I had handy. That was clamped to the bench to hold the part down, then soldered.


Here it is mounted. I still need to strap the grounds to the ground plane and add some decoupling caps for EMC mitigation. Being a 500mW Tx I don't want any of the RF worms getting into the other electronics.

Note the Tx has a 50ohm dummy load fitted. If I accidentally key up the Tx while I am mucking around with the assembly without an antenna, but having a dummy load, will not fry the final stage due to reflected power from not having a load.
Also wrote a script to disable the stabilise mode and switch to manual (fins centered) when a breakwire is broken. The breakwire is cut when the NC separates at apogee.
