SSDR GUI - AGC-T level isn't updated

I found tha SSDR GUI doesn't update AGC-T slide when another client switch the AGC level from [HIGH/MID/LOW] to OFF and viceversa.

Can you confirm this?

    I am also observing this behavior. The SmartSDR UI slider to the right of the AGC mode setting does not update when a FlexAPI client changes the mode setting. It should update to correct AGC level setting of AGCOffLevel or AGCThreshold.

    I don't think it even saves that setting at all. If I have the AGC set to fast and the threshold set to 30, and switch bands the AGC-T jumps to 65 or 70.  I believe the AGC-T should:
    1) autoset to the noise floor
    2) in the absence of that to some low number like 30, not 65-70.

    Each band saves its own AGCMode, AGCOffLevel and AGCThreshold so switching bands is not what this thread was referring to.

    An option to auto set AGC threshold upon band a switch sounds appealing

    Thanks Mark. Yep, that is on the list for S(er)SDR. I am working through what it would require to, before any screen draw, compute the noise floor and only display signals that exceed it so rather than a sawtooth pattern it would simply be a series of vertical lines of various thickness reflecting where signals were. Not as sexy as girating saw teeth but way less invasive on the GPU and way more tolerant of bad connections, lost packets. I will make the waterfall optional as well.
