I left it set to 1 and just waited for transmissions. Audio input: the apps says open the squelch.I used the Mobilinkd TNC config app for iOS to edit the settings. If you’re not receiving data, you’re not going to be able to send data either! Twist the volume button to about half way.Set frequency to 144.390 (SIMPLEX only – no tone or CTCSS). This article is the result of several months of research, numerous emails back and forth with Mobilinkd and other vendors, numerous YouTube videos on the subject, and a lot of banter on social media groups. As the TNC3 sat on the shelf collecting dust, I decided to find a way to use it. I eventually ended up buying a Kenwood TH-D72A, thereby eliminating the need for the Mobilinkd TNC3. I tried upgrading to a Yaesu FT-60R, but could not find the right cable to connect it to the TNC3. Before I figured out this solution, I tried using mobile apps like APRSDroid and APRS.fi for iOS and APRS Pro Ultimate for iOS.Īlong my journey I was told by people who seemed to know more about radios than myself that Baofeng radios just weren’t going to work. Undoubtedly the most frustrating part of this process has been figuring out how to get any device to consistently talk to the Mobilinkd TNC3 and in turn to a radio to send valid data over the air. At the same time, PinPoint supports (RX only) iGate and APRS-IS operation while connected to the Internet.After several months of trying to figure out how to use a Baofeng as a TNC for things like APRS tracking, I finally found a method that works. Once maps are cached, PinPoint can be taken offline, so it's perfect for use in rural areas where Internet access is unavailable. PinPoint caches all map tiles that are requested from a map provider to ensure tile servers are not over burdened and allowing for offline use. PinPoint has built-in mapping and supports quite a few different map providers, including Google maps, Bing maps, Yahoo maps, OpenStreetMaps, including satellite and hybrid imagery. If enough people suggest the feature you have in mind, it will be added to the product roadmap for PinPoint. If you have a great idea for a feature or are running into problems that are specific to PinPoint (after you have exhausted the enclosed Quick Start guide), feel free to send an email to ab0wv at. PinPoint is a labor of love by Frank, AB0WV and is still under active development, so all the bugs may not have been worked out. Depending on your needs, you may need radio equipment and related accessories to make it all work, not to mention the fact that you will need to have a valid FCC license (or the equivalent for your country if you are located outside the USA) for the frequency you intend to use. PinPoint itself is free software for individual non-commercial use. Click the Download button to go to the download page. Many people use PinPoint in their car, out in the field or in their home. PinPoint does not require an Internet connection to operate (after you have cached all the maps and zoom levels you need) and is self contained.

Pinpoint was featured in the September 2018 issue of ARRL QST magazine.įor a comprehensive overview of what APRS is capable of, take a look at the WikiPedia page. It is mostly used as a tool for tracking people and assets on a map, although it is capable of so much more.ĭuring, for instance, a weather spotting event, an incident commander could visually track where spotters are deployed in the field, and direct them away from approaching weather using an area map on a computer screen. During an emergency, it can be used as a location aware tactical communications tool. PinPoint is free software that allows you to visually track and communicate with people using Amateur Radio (”Ham Radio”) equipment.
