So I'm still not sold on buying an add-on radio for a smartphone that I'm going to replace every couple of years, but I have to admit the Linc solution is pretty cool. It does FRS/GMRS, but what makes it interesting is the amateur radio options:
Linc Smart Walkie Talkie is also great for Amateur radio operators! Unlock the dual band (2m & 70cm) feature with your verified callsign and gain access to APRS tracking and Packet Radio capabilities. Linc can join your existing gear and help make some fun projects!
Linc Smart Walkie Talkie operates on 2m & 70 cm band!

An interesting tidbit from a NANOG/DNS post:
"But needing “multiple” DNS Root Zone Servers and coming up with the number 13 appears to be somewhat curious. It seems such an odd limitation in the number of root servers given that a common rule of thumb in computer software design is Willem van der Poel’s Zero, One or Infinity Rule, which states a principle that either an action or resource should not be permitted (zero), should happen uniquely (one) or have no arbitrary limit at all (infinity). For root servers, it appears that we would like more than one root server. But why set that number to 13?"Leading to:
"The desire in the design of the DNS priming query and response was to provide the longest possible list of root name servers and addresses in the priming response, but at the same time ensure that the response was capable of being passed in the DNS using UDP. The largest possible set of names that could be packed in a 512 octet DNS response in this manner was 13 such names and their IPv4 addresses - so there are at most 13 distinct root name servers to comply with this limit."
Looks like Radioddity has a custom branded WLN KD-C1.
