Good afternoon,
I recently installed a complete new Furuno instrumentation package (TZT3, AIS, DFF 3D, VHF, FAX 30, Wind, dual autopilots, etc.). Everything is working perfectly except the FAX 30 is not receiving and the SN is low on all frequencies (about 10). The SS is about 55. I'm using the FAX 5 Pre-amp and I have moved the necessary internal jumper to power the pre-amp.
On the pre-amp antenna installation, I disconnected the ground wire from the body of the pre-amp and routed it back to the main ship bonding ground. I did this to keep from drilling a hole in the 1" stainless riser that the pre-amp is mounted on. Could this be the problem with the signal to noise ration. Does the pre-amp HAVE to be connected to the body or housing?
Thanks in advance for your help and support.
Warm Regards,
Jim
