Hi,

This is normal. The early FT-101 did use a slightly different circuit on PB1076 and used -100V, but this was changed on later models to -160V. However, Yaesu never got around to updating the schematics and manuals to reflect this, so it remains shown as a "-100V" level but in reality is more like -160V.

I think my 101E measures about -170V.

73,

Peter
