I too have had no luck getting info from KVH. I have one of their
DIGITAL GYROCOMPASS units, gyro stabilized fluxgate. KVH product
support in general is bad. I understand that they might not want to
support hobbyist users who hack their products, but its worse than
that. A group of commercial fishermen videotaped the sledgehammer
destruction of a KVH GYRO TRAC mag compass unit and sent it to the CEO.
All had had failures of their GYRO TRACs just barely out of warranty.
Thats OK, but KVH's quotes to repair were about 80% of the new price.
One thing good, is that they were EXCELLENT heading references before
they failed.
