Hi all,
Is it possible to override the built-in 200 Hz high pass filter when using narrow FM? Although the majority of voice intelligibility is probably above this, I would very much prefer to adjust this and bring some of the lower frequencies back in if I can.
73,

Low audio frequencies in NFM mode?
Re: Low audio frequencies in NFM mode?
If you click on the Receive tab and then click the down arrow for the Narrow FM option on the ribbon bar, there is an option for Highpass Filter. If this filter is engaged, it will have a check mark in front of it. If it is disengaged, no check mark. And when disengaged, you will get all the bass response being transmitted. For myself, I like the bass response unless there is some low tone or other anomaly being transmitted that is more annoying than tinny audio.
Anyway the answer is yes, you can definitely override the highpass filter.

That's excellent! Thanks RadioSDR1 for the tip. Some of those useful settings can be tricky to hunt down and I looked in all the options that I could find without success. Happy now!
