Join Eric, 4Z1UG in his QSO Today with Dean Mertz, K0MKT.  Dean and Eric have been friends for almost 40 years after meeting at the local ham radio club, in Southern California.  While their lives have taken them around the World, there is always an opportunity, a few times a year, to catch up on ham radio projects and personal lives. As a software engineer and hardware tinkerer, Dean always has an inspiring project to discuss.  This time its a web based audio adjustment meter, using the Beaglebone Black, for the local DMR mobile radio system.
