So here it comes again, I deleted the original post in the Test Team forum, as there has been no reply so far.Simon G4ELI wrote: ↑Mon Sep 07, 2020 10:42 amPlease post this problem in the Pluto forum if you haven't already done this, add a full logfile. From memory the maximum allowed value may be 49 but it's been a long time...
---------------------------------------
With RX Gain set to 'Manual', I experience an issue on first start of the radio after Pluto has been powered up. While manual gain is set to 50, the gain appears to be set way higher. Changing the gain with the slider immeadiately sets the correct gain. The issue is reproducible and happens only on first start of the radio after powering up the Pluto.
An error "Radio PlutoSDR> Error writing Channel attribute hardwaregain = 50, error 95, Unknown error" is recorded in the logfile. Hardwaregain can then be incremented up to 73dB without generating further errors. May be related to some missing first-time initialization.
The issue only happens when the RX Gain is set to "Manual" and it is independend on the visual gain setting.

PS: I experienced the issue in previous versions as well.
