trcostan #18255 Does the sonde have a MCU that writes to the Si4063? Changing the frequency is just a matter of changing the data in a register of the SI4063 and of course verifying nothing in the RF chain will cause a problem. Do you have a link to a pic or partial schematic of the sonde? I could spend sometime on this sound’s interesting.

I didn't have luck with it, though it didn't really make sense to me. I just know MrArm was doing fine with a genuine stlink and I couldn't manage with my clone or my nucelo stlink. I actually punted and switched to using a j-link interface I have, but that's not ideal either as DFM doesn't expose all the pins I need for j-link. Anyway, I figured the shortest path to victory would be to just go ahead and order a real stlink with the NRST pin. In fact, this reminds me that I need to go do that. lol.
