Interesting update on IK1ZYW Labs on project to achieve remote control of the FT817. Also a pointer to an interesting page on FT817 Accessories, the external keypad project (circuit, manual & firmware available as well as various configurations of components including reprogrammed and tested chip ATtiny2313-20PU, xtal and 4×4 keypad) and the remote display project (pages under construction).
From the external keyboard info:
“…are you tired of hunting needed functions through F+Sel+A/B/C combinations? Do you want to improve your on-the-air proficiency? You can’t help but always press more keys at a time? Or always retouch the frequency when pushing the F button? An external keypad will let you re-discover the joy of QRPing with the FT-817(ND).
The IK1ZYW Keypad for FT-817(ND) is a wired partial remote control for the little Yaesu transceiver. It was conceived during a 6-hour field session at 2700 m.a.s.l. for a VHF contest in August 2008…”
