Details on how to remove the RF Unit PCB can be found on page 91 in the Pro Instruction Manual, in the section that describes how to install the high stability oscillator module. This are diodes which you have to remove. Carefully re-install the main board and all of the previously removed interconnects.

    Re: Expanding TX/RX Frequency Coverage for the ICPRO.

    is regarding the modification of expanding the TX/RX frequency coverage of the ICPRO. If you are the owner of either the ICOM ICPRO or the IC you may I have stolen the below comments from where Karel, OK1DNH. The Icom IC is quite a popular HF/VHF multimode transceiver Described below is a simple modification that can be performed on the.
    After returning all the covers on, I went to page 60 of the instruction manual, to select the installed filter for the 9MHz-1 position.

    I assume no responsibility for your care and workmanship!! Look to the lower middle of the circuit board for silk screening that reads??????

    Simply unplug, tuck the original plug out of the way and plug in a new plug attached to a length of miniature coax, which can neatly leave the rig through the hole on the back panel that contains an earth bolt. Time will tell how much this helps.

    These are the only adverse effects i have noticed with Mr. Then, locate and remove the original 82K surface mount resistor at R Please note that one could put in a potentiometer, but if this is attempted, I would suggest that a 56K resistor be added in series, just to insure that the feedback path does not got too LOW.
