FT-817
Modification instructions for wideband HF settings.
Read the bottom of the last page for full TX!
These instructions are to enable you to expand the HF coverage of your transceiver to 500kHz per band.
Also the modification will extend VHF and UHF coverage and modify some settings as per the table on the next page.
Don't forget it is YOUR responsibility to ensure that you do not transmit out of your permitted bands.
This modification will also clear any memories and individual changes to settings so make a note of these
before you carry out this procedure.
Please note that you are taking full responsibility for any damage caused to the transceiver during this
modification exercise. All normal precautions to protect against static electricity should be followed.
Firstly remove the battery and disconnect the radio from any power source.
Next remove the top and bottom covers
Looking at the front of the radio there are 2 clips on the top and 2 on the bottom.
Ease these clips free of the main body of the radio and slide the front panel off
(taking care not to overstretch the attached ribbon cable)
Next unclip the ribbon cable from the main body of the radio.
Now the front panel should come free and you can then see the jumper positions.
To extend the HF range JP4006, JP4007, JP4008 should be shorted and
JP4004, JP4005, JP4009 should be open circuit
Leave all other jumpers as they are.
Reassemble in reverse order to the disassembly procedure.
When fully reassembled apply power and whilst
pressing F and V/M turn on the power switch.
