How to change the IF output from 10.7MHz to 45.05MHz

Level of difficulty: Easy (no soldering required)
Only apply the following hardware modification if you have some experience in opening
a receiver and manipulating a coaxial cable. Proceed at your own risk! AOR should not
be held responsible for any receiver damage. If you don't feel confident, it is strongly
advised to get help from a qualified technician.
By factory default, IF output is set at 10.7MHz but functions in WFM mode only.
Nevertheless there is the possibility to change the IF out frequency from 10.7MHz to
45.05MHz where ALL MODE is supported. To do this, a coaxial cable needs simply to
be unplugged and plugged into another socket, as pictured below.
Drawback of this method: Receiver overall sensitivity is reduced by 9dBm, which can
be an issue for reception of weak signals.
To gain access to the PCB, remove the top cover.
Remove the top chassis cover (three screws down each edge of the cover).
With the back panel facing you, just unplug and relocate the coaxial cable as pictured
below.
