I recently did the modification to my Yaesu FT-840 to allow it to transmit outside the ham bands. I did this with the intention of being able to use it on the 160-190 khz Experimenter's Band but the mod only opened up the transmit capability from 1.800-30.0 Mhz. Is there any way to enable this rig to transmit at 160-190 khz?
