I appreciate all the suggestions to run my Z3801 under Linux, I found a website for Lady Heather here: http://www.ke5fx.com/heather/readme.htm is this the right location to watch for version 5.0 to appear? it doesn't mention the Z3801 in the earlier versions, so I guess more info will be revealed once the 5.0 flavor appears. I am kind of surprised there's nothing lurking out there already, linux and gps seem kind of destined to work together in some mysterious IoT things. many thanks, walter -- Walter Shawlee 2, President Sphere Research Corporation 3394 Sunnyside Rd., West Kelowna, BC V1Z 2V4 CANADA Phone: (250) 769-1834 walter2@sphere.bc.ca WS2: We're all in one boat, no matter how it looks to you.
