Mmm, have to watch that greeting "Hi Jack" around an airport... Might get you in trouble.
Using the KPA utility (or the remote server, haven't used it) works well for this, if you're running something like TeamViewer to control the home station computer (and then the radio). That's what I do on the K line, everything is accessible on a laptop, iPad, iPhone, Nook (well you get the idea). SUPER slick and I can even 'see' the P3 because I leave the web cam pointing at it before I leave (via Skype, same as the audio). Pure nerd food. ;o) 73 Mike, nice to see you on this group too, Rick, WA6NHC iPad = small keypad = typos = sorry ;-) > On May 22, 2014, at 12:00 PM, Michael Walker <va...@portcredit.net> wrote: > > Hi Jack > > Thanks for the detailed reply.
