Did you get it up and running? I have two TK880s and a Ham Gadgets ID-O-Matic III. I've run all the cable and wired it up but it's not transmitting. Something is wrong with my wiring.
not yet. its stilling on my desk now... waiting to be put together. I have been playing with my GR1225 repeater in the meantime... I will def update here once i do. Check the low and high key settings.
do you have any plans for making it battery powered? I was thinking of building this as a grab-and-go box w separate battery pack / solar charger for camping and trips to the lake.
