UPMan,
For as long as I can remember, it seems that the standard attenuation option on scanners is 20dB and remains so. This amount of attenuation is mostly useless in helping with interference issues. 10db would be much more useful. What would be extremely useful would be at least 3 levels as options. 6dB, 9dB and 15 dB. It is really helpful that it is possible to option attenuation by site, but at 20dB it is enough to kill reception instead of helping with interference. One can just use a lower gain antenna, but of course that affects everything.
I expect the attenuation just inserts a fixed resistance somewhere in the RF path of the scanners, but if it is lowering gain of an amplifier by some controllable bias, it would be nice to have a firmware update to at least change it to 10dB. 3 levels would be outstanding.
