They are from the original TAPR Mic-E encoder device -- the decades-distant 
forerunner of the TinyTrak, etc.

Like a TinyTrack, it was a transmit-only device. It was intended to be inserted 
in series between a mic and the radio's mic jack -- hence the name "Mic 
Encoder". .   Unlike the TinyTrack, you could select one of 16 canned messages 
in the field, with a 16-position rotary switch (the same canned messages that 
show up in Kenwood APRS menus, or on the TinyTrak config menu) --AND-- you 
could select several canned paths from a similar rotary switch.   Details on 
this now-discontinued historic device here:

<http://www.tapr.org/kits_mic-e.html>


Note that "Mic-E" actually has at least 3 meanings:

o    The highly-compressed position data format that puts part of the posit 
data in the destination field.

o    The original TAPR hardware device that produced this kind of packet.

o    The technique of   APRS-packet-burst-on-unkey    on a voice channel.  [The 
Mic-E data format was invented to make the shortest possible burst in this 
APRS-after-voice mode.]   Today, the TinyTrack and all the Kenwood APRS radios 
support this mode of burst-on-unkey.
