All I can say is WOW. What a difference. I have owned my MP (plain not Mark V) for 4 years and never messed with the carrier offset. I have the Yaesu 2.0 filters as well as the 2.4. The new settings make the shift and width much more responsive. TNX es 73, George K3GV DX: Long may it live ! If it isn't LOGic it isn't LOGging !
