[R-390] Another 390A Carrier meter question

[Flowertime01 at wmconnect.com]

Tim,

We used the R390A with the R390 IF deck for DF.

Also seen R392 used with loop antennas for field DF.
And other radios used for field DF.

They were not calibrated to any extra level.

You use antenna position and relative dip of meter.
An exact value was not required.
