Subject: FT-920 Modification


Greetings,

We have received many calls regarding the frequency expansion modification
for the Yaesu FT-920 which is currently posted on your web site. The zip
archive contains an executable file that is meant to "flash" the EPROM of
the transceiver to allow the transmitter to operate outside of the amateur
bands.

This software will cause irreversible damage the EPROM in US version
transceivers. Replacing this EPROM is quite costly and is not covered under
warranty. Unfortunately, many FT-920 owners have found this out the hard
way.

To help prevent additional damage to the ever-growing fleet of FT-920s, we
request that this modification information be removed from your site. We
appreciate your assistance, and would be happy to answer any questions you
may have in this regard.

    between R2544 and Q2510.
