Don, is your software able to pass USB frequency changes "remotely" to the Flex radio server for relay on to the Steppir? Sorry for my neophyte question but when I finally get my antenna/tower plans implemented I will only operate from a remote location (on the roof of my condo building). My Steppir there will have a USB cable connected to the Flex server in a nearby roof maintenance room but I'll be "elsewhere". I'm not sure if my MacLoggerDX (running on my local Mac) can effectively command the Steppir on my roof over the Ethernet connection that I will have to it. My alternative is to have a Mac/PC in the rooftop shack and connect it directly to the Steppir -- but that complicates the overall remote model that I'm trying to implement. Thanks.
