I am wondering if anyone has experience in "opening" (modifying) the U.S. version of the rig to operate on 4m band?
I have recently become a happy owner of this transceiver but failed miserably in my attempts to make it transmit and receive on 4m band. As soon as the dial hits 70.000 kHz the output power disappears. When the dial hits 72.000 kHz the it resumes transmitting.
I have seen and done this modification - http://radioaficion.com/cms/ic-7300-wid ... ification/
just to no avail.
Any further ideas will be much appreciated.
