Re: New RSP2pro - Dissapointing Results

Some of these RSP2pros had internally reversed A & B port connections. That is, the A input connector is internally connected to the B port and vice-versa. I have also noticed that strong signals can bleed over into the unused antenna input.

Re: HF weak signal reception in presence of noise

glovisolL That's an interesting experiment you've done. Very helpful. I have a question. Any ideas why the noise floor is inversely proportional (more or less) to the RF gain setting? More RF gain lowers the noise floor. In my case it was varied from -116dbm at min RF gain to -135dbm at max RF gain....

Re: The Hi-Z connection

That's good to hear. As to HF reception there have been zero sunspots for 30 of the last 31 days.

Re: Audio recording problem

After the update my PC had the default recording device set to microphone. I had set it previously to Stereo Mix. Rolling back your system shouldn't be necessary. Check your audio playback and record settings first. To access the Sound control panel: right click on the Speaker Icon. Select "Ope...
