So the spoofed calls seem to have stopped since I did the SIT tone. Didn't think that would work.
@eternalyperplxed I just found an audio clip on youtube of the SIT tone and the recording "this number has been disconnected". I used tasker to roll directly to voicemail.
@sycophantic
Love it, nicely done. At some point I also need details on your Meshtastic and ADS/ACARS stuff. I got a Heltec v3 for MT and a ADS-B antenna for my RTL but want to get something stationary mounted higher up and more powerful for both.
