API to change Direction Finding target frequency in realtime

1

I have an idea that may be very interesting (and hopefully not abused)

I monitor local public safety radio (700/800MHz P25) and since it’s a trunked simulcast, radios transmit on a mobile frequency and the towers listen and rebroadcast across all towers on a base frequency.

The Mobile frequency is much lower power and is the only signal from the radio, otherwise listening normally would be a signal from multiple towers simultaneously.

The control channel has info regarding who’s talking (Radio ID), Talkgroup, base frequency, band plan, etc).

What if I pipelined the mobile frequency from my scanning software Into KrakenSDR so it only tunes to the mobile frequency of a desired radio and finds its location?

It should be possible, if the radio is in range, but is there a way to change the frequency of the Kraken Direction Finding Software without using the web GUI?

Some info here on changing the frequency programatically: 13. Appendix · krakenrf/krakensdr_docs Wiki · GitHub

Be aware that changing center frequency takes about 2-3 seconds due to the need to recalibrate on each center frequency tune, so short signals can be missed.

I’ve already investigated this. You can do it with boatbod and some heavy python scripts.

Best thing to do is your your favourite AI tool (mine is Gemini) in Pro mode, and have it write the python for you.

Transmissions are so short usually with trunked networks it would be hard but not impossible to do
