A/D Overhead Level
I'm experimenting with different configurations of distribution and filtering on the receivers out the VK5ARG remote site (http://kiwisdr.areg.org.au:8073 and 8074). Right now one of the receivers is just ending up just slightly in the overload region at night-time.
Is there a way to get some idea of the A/D overhead? e.g. the maximum observed A/D reading in the last 1 second (or some other convenient period), in dBFS? This would give me a good indication of how close the receiver is getting to overload and adjust the front-end accordingly (it'd also open the door to implementing a basic external AGC...).
Being able to query it via the /status interface would mean I could plot it over time, see how often I'm getting near (or hitting) overload, and decide on the best course of action to make the station perform the best it can!
I work with direct-sampling HF receivers at my day-job, and the A/D overhead level is one of the key metrics we look at in seeing how a receiver is doing when exposed to the HF large-signal environment. Overload count is the other (which I can probably get if I tie up a channel).
Maybe this exists somewhere already?
