One's for talking on (Coms - Communication) the VHF radio

 

The other's for radio assisted navigating (Nav Coms)

 

- the NDB - Non Directional Beacon where you dial in the frequency and the needle moves to point to it (yeah, there's a bit more to it ...)

 

- the DME - Distance Measuring Equipment - ditto but digital read out

 

- the VOR -

 

etc.

Com refers to the usual VHF radio

 

Navcom refers to a unit with the same radio plus a VOR navigation decoder included and a VOR display instrument.

 

Fairly obsolete now especially in rec. flying not much VOR coverage at the levels we fly. i tried one in a Bantam once had to get hypoxic before it would start to work. ADF not much good either, too much crab angle in a Bantam with a crosswind!

 

Usually they had a nav side and a com side, the nav part having its own antenna and separate receiver so both functions could be used simultaneously. Some particularly crude types like the Narco Escort shared the reciever and had to be switched manually between functions.

Radio Fail procedures.

 

You can put comm messages over the ident frequency of some navaids in radio fail situations near airports in control areas. This might have been discontinued. Some ATC person may clarify..Nev

As stated above, it is a VHF and VOR in one box. The VOR is not obsolete, it is still used regularly by those navigating by instruments.
