Do you have any idea why the range and clarity suffers from being
digital? I don't know anything about digital, but I know that one of
the things touted about the 900 mhz digital cordless phones is that
they have a digital signal, and because of this it has greater range
and a more clear audio signal. I tend to disbelieve this myself,
since I accidently bought an anolog 900 mhz cordless phone around
Christmas time. I went looking for a digital, on the box it said
digital security, and I took that to mean it was a digital phone. In
the end digital security meant the security codes, it uses to insure
someone else doesn't tap into your phone with another cordless
phone. Anyway, recently my Brother bought a true digital 900 mhz
cordless phone, we can hear mine on the scanner, and we can't hear
his, this part is fine, but out testing shows the distance and
clarity are the same almost to the very foot.
take care,
Martin
