No mention of Vox but I can't see how there would be any if the relay is picked via a 12volt mod via the Mic PTT. If the rig is generally working OK (SSB) then I guess it's up to Dale as to the next move. If it was my issue then I would source an appropriate relay and restore the rig to its "as built" functionality. Best regards JB

Dale didn't mention whether the VOX worked or not. It wouldn't be that difficult to put a fet (2N7000?) in place of the last 6EV7 section to retain VOX. If the VOX (Semi-Breakin) doesn't work then the 'dit chop' doesn't matter! Of course the transmitter is much less pleasant to operate, at least to me. :-) -- 73, Garey - K4OAH St Charles, IL Drake 2-B, 2-C/2-NT, 4-A, 4-B, C-Line and TR-4/C Service Supplement CDs <www.k4oah.com> John Brown wrote: > > I guess there will not be any VOX capability if it is hard wired to the PTT. > > JB > > *From:*[email protected] [mailto:[email protected]] *On Behalf Of > *[email protected] > *Sent:* Wednesday, 28 December 2011 12:15 PM > *To:* [email protected] > *Subject:* [Drakelist] strange relay setup for T4X > > Put the T4X on the bench today, noticed the relay had been changed out.
