The rubberduck is a airband antenna. The battery life sounds more or less accurate. Did you compared it side by side whit a different receiver? The fact non of the 50 frequencies received a signal is a bit weird.
Yes, I did use the airband antenna on the airband and did manage to hear some local traffic. But I also tried 4 other antennas, two were telescoping and two were multi band amateur antennas. Side by side comparisons were with an SDS100 for P25, the DV10 failed that test miserably by not copying anything. Compared with an R30 for the analog FM business band freqs and it never broke the squelch.
While there are others who apparently have had some success with the DV10 my experience was otherwise. I hate that because the radio is built like a Motorola, nice to handle, solid, etc. I guess Yaesu did their part but AOR failed miserably.
