On a ham radio forum (eHam or QRZ) or in the ham radio magazine "QST" I saw a post or letter to the editor that the radio manufacturers should design mobiles/handhelds to include P25 and trunked system scanning capability. The ham stated that the need was hams working an emergency don't need to be saddled with carrying one more radio in order to keep up on the information gained by listening to an agency's radio system. Presumably this is the reason most ham radios now have the capability of scanning everything from the AM broadcast band to about 1300 MHz, excluding only cellular. The post or letter did not receive much interest from other hams.
The features on these "ham scanners" are not as conveniently accessible as a scanner, such as having a lockout button or as simple of a procedure to enter frequencies, but I find they are more sensitive and built more solidly than scanners are. Since we don't have much trunking in the area I live in, I don't carry my handheld scanners around that much. If my ham handhelds included trunking/digital I would carry them even less.
If the manufacturers think there is a demand for ham radios to have these capabilities I would suspect they would start making them. I'm not holding my breath.
