[SCCC] FW: Yaesu rotor conversion to 220 volts

[marko.L.myllymaki at nokia.com]

Hi,
Thanks Marty and Chip,
I got instructions already from Jerry N6UME at Vertex.  So there is away to do it and it looks simple.
I would also have transformer 110/220 at the location anyway but rotor will most likely be left there so wanted to know this for eventual new owner of it.
Thanks again, 73 Marko

Marko, Yaesu should be contacting you shortly on this. It's easy.
