Anyone interested in trying out a Mac app I just finished, go to http://nf4l.com/rotor/rot.htm It's for turning antennae whose control boxes understand the DCU command set. It should run on SnowLeopard and up (Intel based Macs). It's my first Mac program. Next up is porting K3 Texter to the Mac. Any questions, please contact me off list. 73, Mike NF4L
