Hi all,
Can someone try to explain this to me ? Why is Tim hearing more signals on
the Pro than th Omni V ? Is the Pro that much more sensitive ? -or does the
added filtering improve the signal to noise ratio ? -or maybe the DSP is
clearing up local pulse noise that was covering over weak signals on the
Omni V ? Do any of my guesses make sense ? -other explanations ?
tnx & 73
