I think the Pro-2004 is a heck of a good scanner. However,  one problem
that it has is front-end desense. On two that I have tested, they
lost 38dB (!!!) of sensitivity when connected to a good antenna
that was letting in -15dBm of FM signals (sensitivity loss was on VHF-Hi
Band). Turning on the attenuator on the back actually improved sensitivity
by 28 dB. I have found that using the radio shack FM reject filter in
front of the scanner seems to help, but it is 75 ohm with wierd (F)
connectors, which is a bit of a kludge.

]Tape On/Off relay (for use with the "remote" jack on a tape player to
