G'day, I use Spectrogram v6.6 with the 10 minute time limit, not a problem. > > how do I do a screen capture under Windows? In Spectrogram: Stop the recording then: Function>Save Image>Window Image - select jpeg and the rest is routine. Works for me. Regards, Mike VP8NO (IOTA SA-002) GQRP 10148 QRP-Canada #57 K2/100 #1400
