This has Ben hashed in the past. I know you can click the MOX with mouse then the space bar will key it because of the memory effect. I also realize box will work but as we near version 2.0 I look forward to using my 6500 in the Mobil via remote. In this case I would like a PTT button . Has anyone got something working? I have a PIPO x8 working remote so this looks like a option.
