I have an Openspot 1 that I have used on D-Star successfully for many years with my Icom ID-51. This week I created a profile for my Yaesu FT70D, a radio that I have used successfully on a Pi-Star hotspot. I find that using the FT70D on the Openspot I can receive signals without problem, but I cannot successfully transmit. The Openspot does not respond in any way when I hit the push to talk. I have tried all the suggestions I have seen on this forum and on the internet without success. As an experiment I tried using my Yaesu FTM300D and found that it successfully transmits to the Openspot. So, the first question is, do you know what's going on? And the second question is, if I purchased an Openspot 4, does that model have any known issues working successfully with the FT70D? Thank you for your time!
