Works Great for APRS!
This product does it's job!If you're a Baofeng owner getting into aprs and want to use your smartphone and aprsDROID -- this is your ticket!I'm using an old android phone with no service as a dedicated aprsDROID unit. The cable plugs into the headphone jack (I have to use the supplied cord extension for connection reversal on older phones), and it plugs right into the K-jack on my UV5R.I launch aprsDROID on the phone, put the BF on 144.390, set VOX to 1, squelch to 1, volume on both phone and BF to about 3/4, and viola!Easy to send messages, check WinLink email, get weather and everything else APRS offers. The cable seems high enough quality to warrant the price.
