The unofficial English language Mizuho website is back up at a new location: http://www.mizuhoradio.com
Some of the manuals and schematics haven't been uploaded yet, but everything else is there, including more new pictures and specs for various Mizuho gear.
The Mizuho reflector (mailing list) is now on Yahoo! Groups. The old reflector on qth.net is effectively dead. If you have any Mizuho gear or are just interested or curious, please do join us. The Yahoo! URL is: http://groups.yahoo.com/group/mizuhoradio/
If you don't want to register with Yahoo! you can still join the group. Follow the directions at http://www.mizuhoradio.com
on how to send an e-mail to be added to the reflector.
For those of you who don't know Mizuho, they are a family run business started by a former Trio (Kenwood engineer over 30 years ago. In all that time they have made strictly QRP rigs and shack accessories. They are best known for their HF and VHF SSB/CW monoband handhelds, which were made from 1981 until 2002.
