Sadly the MARS Network has been almost completely dismantled.
Well - MARS was cool back in the day, but when you can get a good satcom connection for under $3/min - then HF is out.
HF today makes for a better-than-nothing backup comms channel, but technology has really advanced.
Two satcom outfits offer service here, and for very good price points. If I still traveled in the Bush as before, I would carry one as well. Luckly, I’m past that.
Still, working DX is still a hoot.
Getting ready for the big rodeo up in Tucson?
