The 5V is sourced through a 100 ohm resistor and the final PA module hangs a 3.9V zener on the line, so you will see ~3.9V. Still enough though to switch the Transverter<br /><br />Dave<br />G4FREg4frehttps://www.blogger.com/profile/14201949618514029864noreply@blogger.comtag:blogger.com,1999:blog-9071048343455395511.post-72638656407840727462011-01-27T11:13:24.057+00:002011-01-27T11:13:24.057+00:00Yes it would Tony with a TX off delay to cope with...Yes it would Tony with a TX off delay to cope with SSB. I think I will make the mod as it looks very easy to reverse if ever the FT817 was sold (very very unlikely!).Roger G3XBMhttps://www.blogger.com/profile/13673890140751539870noreply@blogger.comtag:blogger.com,1999:blog-9071048343455395511.post-14138043406090159052011-01-27T10:27:08.509+00:002011-01-27T10:27:08.509+00:00Hello Roger
