Raytheon RL-9 Small boat radar problem.
We have a non working Raytheon RL-9 small boat radar; probably 10 to
20 years old? Investigations seem to indicate that the receiver section of the printed circuit board of the mast mounted scanner, transmitter receiver unit is defective. It appears that there is no noise reading at TP5 (test point) on the receiver/modulator PCB CNM179 printed circuit board. The complete mast unit is numbered # M52559. Other functions (e.g. the controls of display unit) seem to be OK. Some of the parts seem to be made by JRC (Japan radio Co.). We were able to download the user/installation manual but not a deailed circuit diagram and test readings. Anybody have any advice about the possibility of having the mast unit repaired, hopefully somewhere in eastern Canada. Any advice appreciated. terry and alfred PS. We also posted elswhere and were recommended to come here. |
