Why Furuno 1945 Marine Radar data and marks not displayed in transmit?
If data and marks are not displayed when transmitting on your Furuno Marine Radar, the SPU board may need to be replaced.
What to do if Furuno 1945 Marine Radar power is on, operated STBY/TX key to transmit, marks and letters appear, but no echo appears?
If the power is on, you've transmitted using the STBY/TX key, marks and letters appear but no echo is present on your Furuno Marine Radar, check that the antenna cable is securely fastened.
What to do if Furuno 1945 set GAIN to maximum with A/C SEA set at minimum, marks and indications appear but no noise or echo?
If the GAIN is at maximum and A/C SEA is at minimum, and marks/indications appear without noise or echo on your Furuno Marine Radar, check the continuity and isolation of the coaxial cable. If the issue persists, the IF amplifier may need replacement. Also, check the coax line for a fastened connection. If the connection is good, replace the SPU board.
What to do if Furuno Marine Radar marks, indications and noise appear but no echo?
If marks, indications, and noise appear but there's no echo (and the transmission leak representing your ship's position is absent) on your Furuno Marine Radar, check the magnetron current. Also, the modulator board or the SPU board may need to be replaced.
