Baofeng Tech APRS-K2

John reviews the Baofeng Tech APRS-K2 cable:

“BTECH APRS-K2 TRRS / APRS Cable is a simple way to start using APRS by using devices you already own. The BTECH APRS-K2 Cable will quickly connect your radio to APRS by using virtual TNC (app driven) on your tablet or device. The APRS-K2 cable is built with a custom circuit board that will automatically adjust the audio for clear packet transmissions with minimal adjustment; along with protecting your devices from strong over modulated signals.”

So, take your radio, this cable, and an app on your tablet/phone and you are ready to go!

SharkRF OpensPOT Review

John reviews the SharkRF OpenSPOT:

“Hotspots were not developed to replace repeaters, but rather to supplement them. In areas where there is No repeater, a hotspot allows the user to connect directly to a digital network via the internet. In areas of Heavy repeater use, a hotspot allows the user to access the network without competing for an available time slot.  If your local repeater gives you access to a network such as DMR-MARC, an openSPOT can give access to networks such as Brandmeister. You will now have access to the best of both worlds.”
