Yes - effective with MCU 4.57 for AM transmit
MCU 4.57 / DSP 2.79, 10-24-2012 * AM TRANSMIT CAN USE THE FM FILTER: The wide (FM) crystal filter can now be assigned to AM transmit as well as FM. This can potentially free up a crystal filter slot for customers who were using the 6-kHz filter only for AM.
and MCU 4.60 for ESSB transmit:
MCU 4.60 / DSP 2.80, 11-17-2012 * ESSB TRANSMIT CAN USE THE FM FILTER: The wide (FM) crystal filter can now be assigned to ESSB transmit as well as FM and AM. This can potentially free up a crystal filter slot for customers who were using the 6-kHz filter only for AM/ESSB. NOTE: The 6-kHz filter is still recommended for high-performance ESSB and AM receive, as it will provide significantly better close-in dynamic range than the FM filter.

Folks, Can a single Elecraft FM filter support AM and FM transmit and receive for occasional use with a K3?
