[JRC] JRC NVT-56 Base Mic

[Dave N9EWO]

Perhaps a strange question here..but any help would be most useful to =
me....

Does anyone know if the JRC NVT-56 Base mic (accessory mic for JST =
135-145 and 245 transceivers) has a internal mic pre-amp of some kind =
(like Kenwwod and Icom does), or is it just a electret condenser element =
in a case with no other electronics? Any trimmer control on the bottom =
to adjust gain ?? If an amp does exist what voltage input exists (8 =
volts ??)

If one has this mic and would have a look if and see if a schematic =
exists and check these points (whatever manual might come with it), that =
would be great. Thank You.

Regards,
Dave N9EWO
