Radio navigation set to make global return as GPS backup

GPS killed the radio nav in 2010, but a high-def version is set to return.


Enlarge / This is the way we used to find our way around.

Way back in the 1980s, when I was a young naval officer, the Global Positioning System was still in its experimental stage. If you were in the middle of the ocean on a cloudy night, there was pretty much only one reliable way to know where you were: Loran-C, the hyperbolic low-frequency radio navigation system. Using a global network of terrestrial radio beacons, Loran-C gave navigators aboard ships and aircraft the ability to get a fix on their location within a few hundred feet by using the difference in the timing of two or more beacon signals.

TYT MD-9600 Shipping Soon

TYT MD-9600 Shipping Next Week

Below is an email from

Believe it or not, the TYT MD-9600 is close to becoming a reality. If you haven’t been following this closely, the MD-9600 is a dual band (UHF/VHF) mobile radio from TYT that supports tier II DMR (as well as analog). Reasonably priced DMR mobiles have been scarce, which is why this radio got a lot of buzz when it was first announced (over a year ago). Since the original announcement, TYT has surprised us by making it dual-band, meaning this is now a radio that is fully capable of replacing most everyday mobiles!

TYT is telling us that our initial order will ship from their warehouse on Tuesday (8/8). We’re having it shipped express, so we expect to have them in our warehouse within a week of their shipping from China. We plan to work overtime to get all pre-orders shipped on the day they arrive!This radio is $359.00 and we expect demand to be high for a while after release. If you’re interested in getting one soon, we suggest that you pre-order ASAP.
