I have a new FT-70DR that connects to my Openspot, but will not transmit on the Openspot. It works fine on FM working my repeaters. I can only listen to rooms. Openspot works fine with my DMR and D-star radios. Somebody told me to upgrade my FT-70DR firmware. I did but I am not sure I used the correct version, maybe it was not for the USA version? The result is now it shows a firmware error and I can not use the radio at all. Please somebody tell me what I can do.
