If you are sure that you see the warmup messages you are communicating with the radar
and the news might be bad: your magnetron may have died. They have a limited lifespan -- 1500 to 3000 hours.
To verify that you receive data from the radar, stop OpenCPN
, set VerboseLog=1 (or even more up to 31, 1/2/4/8/16 are "bits" that add up) in the conf/ini file and start OpenCPN. Stop it again and check the log file for records like this:
radar_pi: ProcessReport xxxxxx
radar_pi: 0x02a5: next-state-change <n>
If you do have to buy new we humbly suggest a Navico
radar. We are able to support these much better as all the three active developers for the plugin all happen to have a Navico
