I've suddenly got the itch to do some portable QRP work with my tiny Yaesu FT-817 HAM Radio, which I picked up in the UK a few years ago ... it has been gathering dust for quite some time. So I charged the internal battery and checked it over. It's then I realized that since I purchased it in the UK, the 2m band was restricted to just 144 - 146Mhz which is pretty much useless in Chile as ALL of the local repeaters are located in the upper 146-148Mhz. Also, the 40m band is restricted to 7 - 7.100Mhz; again in Chile I can use up to 7.200Mhz, so this has motivated me to extend its TX/RX capabilities or 'wideband' modification. The original FT-817 was very easy to extend with free software on the Internet, but I guess the FCC didn't like that so my newer ND model, requires a fiddly hardware modification.
Basically you have to strip off the top and bottom covers in order to expose and release the front control panel from the main chassis. Then using a fine tip soldering iron and a steady hand, modify the jumper settings as shown in the picture above. Fairly simple, in my case I needed to close the far left jumper and remove solder from the middle jumper to complete the mod. After the the radio is reassembled, it requires a hard reset holding the F and V/M buttons whilst hitting the power on button.
I checked the 2m band, it's now fully open :-)
