WSJT-X 2.5.0-rc4 on Win 10 x64.
I successfully did a few runs of Frequency Calibration.
Additional runs are giving me garbage like:
18:41:59  20000  1  1500  1499.976    -0.024  -91.0  -99.0  *
ÀQN
18:42:06    315  1  1500  1499.782    -0.218  -91.0  -99.0  *

For some reason am getting Level -91.0 and S/N -99.0 when there is plenty of signal, not exceeding 49dB in the green.
And then there is a line with 4 garbage characters between.
Some frequencies are giving normal reports likea local beacon does:
18:27:59    425  1  1500  1499.650    -0.350  -31.2   68.8  

Any ideas?
