The Kenwood TH-D72A is an APRS equipped dual band HT. It has both a GPS receiver and a TNC inside it. It isn't meant to be a replacement for the manual but these notes on getting started may help someone that is just starting out with the D72. If nothing else, turn it on, make sure the TNC and GPS receiver are enabled. The top (A) frequency should be 144.390 MHz... channel 0 (zero) on our radios. The TNC should be set for APRS12. If it is going to be used for packet, set it instead to PACKET12 with 144.970 Mhz being on channel 990. The lower (B) frequency can be used for voice. The TNC can be used for data applications like Winlink Express as well as for APRS.
