Re: Question about replacing the battery Pack
I'm thinking about making a simple rectangular battery tray out of either sheet metal or polycarbonate to go under the radio and attached with the lower cover screws. I know such a design would hold

Re: Question about replacing the battery Pack
From the graphs I've studied it seems like 9.0 volts is more realistic for a 100% discharge, both for the battery and for the radio. On that basis I would consider it to be ideal.? ?Ymmv, fwiw,

Re: Question about replacing the battery Pack
I had a question regarding this 3 cell Li-ION pack with the 3d printed chassis and cover.
With a 12.4V peak, 11V nominal, and 8.25-7.5V cutoff voltage how well does this work with the 817?
Does it

Re: FT-817 almost powers up
I did this with a wire and the power-up sequence remains the same -- LCD black, relay click on the filter board, powers off.
I'll add something semi-permanent and see what the voltages look like.

Re: FT-817 almost powers up
This is used on transmit - the limit current would probably be quite high >2A.
I would not expect it to trigger at 0.5A even if it was active during RX as this is within the normal operating current

Re: FT-817 almost powers up
The finals are straight across the 13.8US (power unswitched), so they might well drag the supply down.
If the controller decides the voltage is too low, it will immediately power down.
