MARS is our next door planet or it relates to "Pumping up the Volume", but what does it have to do with Amateur Radio? This week in Foundations of Amateur Radio I look at modifying your radio with a so-called MARS/CAP modification. What are the implications, what should you be aware of and what are the risks? The Amateur community rarely talks about such things and ignores it with: "Here be Dragons!", but really we should be leading the charge and discussing this professionally and comprehensively, rather than hiding it under the rug. This weekly podcast can be downloaded from http://podcasts.itmaze.com.au/ and found on iTunes by searching for my callsign, VK6FLAB.
