squelch threshold in Kiwirecorder
Would someone kindly explain to me how the squelch threshold parameter works in Kiwirecorder? I tried setting it by using the standard S unit to dB relationship (6 dB/ S unit), but it doesn't seem to be working. Here's an example:
I am monitoring a rather weak station on a certain frequency, say 4.5 Mhz. After careful observation beforehand, I notice that the best signal, clarity and least noise happen when the station signal reaches S7 on the KiwiSDR online S meter. So, I set squelch threshold for 42 dB (7 S units x 6 db/ S unit). My logic tells me that anything under that signal level (S7) shouldn't be recorded, but that's not it appears to be working. So, how does it work and how would I set it up in this example?
Thanks in advance,
Jon

the squelch threshold is relative to the moving average of the field strength and not absolute. When I use the squelch I usually set the threshold to either 10 or 15 dB.
