When you record in Console use 16 bit not 32 bit then they work (default it 32 bit)

Very interesting and clever development. I managed to eliminate a strong Polish station on 94.7 to reveal France Blue Nord! OK it's only a local station - but it proves it works. More testing to see if when a strong signal is eliminated the RDS data from a weaker signal will come through. What I did find is the RDS from Azer FM came through nicely, with the FM Canceller set up for RMF from Poland, but I'm not sure if that was because RMF had faded anyway.

The only I problem I have with SDR# 1772 is that with the FilePlayer the Frequency Control option has no effect. On SDR#1655, with the waterfall widened out I can click on a specific spot on a frequency, on the waterfall, and it moves to that frequency/time. On build 1772 it won't change frequency, but will move to the time on the pre-selected frequency. Do you have the same issue Peter?

Unfortunately I deleted my Es IQ files to make space on my external HDD a few months ago. Only one folder on my laptop's internal SSD remained.
Yes, frequency control in file player stopped working from version SDR#1700. I use SDR#1430 usually for playback, although I will also check with 1772 from now on.
