[chirp_users] Yaesu 857D upload

[Rod Bater]

Hi,
I have a Yaesu 857D and can download from the radio to Chirp with no problems but cannot upload from Chirp to the radio.

I get the the following:-
“Failed to communicate with radio.
Radio did not Ack block 0 “

Any ideas how to overcome this problem?

Thanks
