Man-Portable HF Antenna strategy

For the off-grid field radio operator with limited weight & carrying capacity, what antenna options do we have? Actually, quite a few! Let’s talk about smaller, lighter, and more efficient antenna options. Hello Operators.For the past few years, I have been guilty of choosing the most rugged antenna options available. At some point, reducing sizeContinue reading “Man-Portable HF Antenna strategy”

OTA Micro-Blogging concept update

When we use JS8Call, we usually synchronize the time to within a few hundred of milliseconds, using either NTP (Network Time Protocol) or with a GPS. This works great untilContinue reading “Off Grid JS8Call Time Sync No GPS or NTP needed”
