My fax 30 is not receiving any message. After contacting Furuno Italy i was told that they do not inspect the internal components. The solution is changing the main board since no diagnosis or repair is anymore done by Furuno. The cost of a new main board is almost the same as a new fax30 and therefore this strategy is clearly discarded. Do you know of other places were technicians still do the diagnosis and repair work? The test procedure was carried out by a friend ham (see attachments) and was successfull, the antenna properly tested (I use a long wire 15 meters) but the signal is not properly elaborated in the main board (???) . I use it with an old windows 7 PC.
