CHAPTER1
GENERAL DESCRIPTION
1.1 INTRODUCTION
The R.V.R. model URP are very compact externally powered FM exciters
which may be used as an economic alternative to alow power exciter or
as a portable unit.
1.2 ELECTRICAL DESCRIPTION
The URP is capable of either 10 watts or 2watts with the power output
being controlled by a switch on the front panel.
The URP/2 model is capable of 2 watts only.
Both units operate from an external power supply which must be regulated
to ensure stability of the operating frequency.
The supply voltage may be in the range of 12 VDC to 13.8 VDC.
Power output will very somewhat with the applied supply voltage.
1.3 SPECIFIACATIONS
Please refer to Table A for the elctrical specifications and
Table B for the mechanical specifications.
