Frequently Asked Questions
Q: Do you make a cable for my USB GPS that connects to my APRS Radio/Device?

A: No. The USB protocol is known as a master/slave protocol. The typical setup would be the USB device and a computer. One half is dumb and the other is smart. Unfourtunately, the smart end is usally the computer running a specific device driver for that GPS. Common devices like the Kenwood D7/700 radios, OpenTracker, TinyTrak and HamHUD depend on serial communications since there is no real dependancy on the device to control the GPS.
Q: What is the cost of a tracker/radio interface cable?

A: $20-25

We offer two kinds of Tracker/TNC cables:

Tracker Cables: These include connections for the radio and power option to power the tracker. Power options include Lighter Plug, Pigtail with installed PowerPole connector and Bare End Pigtail. A cable with a lighter plug or PowerPole costs $25 per cable. A bare end pigtail power cable costs $20 per cable.

TNC Cables: We also have a TNC to radio only cable that do not need a power option. These cables cost $25 each.
