This is a Bluetooth(tm) CAT interface for FT-817, FT-857 and FT-897 (possibly FT-100 too). It plugs directly into the ACC socket on the rear of the radio, it is self powered and it should be the definitive solution to wrong/missing/unrecognized drivers for USB-to-serial adapters, cables running around the shack, ground-loops, ...
|CAT BT adapter on FT817 with internal battery|
I could use the CAT signal two rooms away in near line-of-sight, which is more than 5m.
This homebrew accessory is 2cm wide and 5cm long. The current drain has been measured to be:
- ~40mA when not paired (and no other BT devices around, weird)
- ~10mA when paired and not sending data after few seconds
- ~30mA when paired, sending data and few seconds thereafter
I also had a plan: let my FT817 accessories go wireless. This would require an independent power source for the keypad or (interactive) frequency reader, A.K.A. batteries. But besides being a nice system integration exercise, would that be really useful?
