[Boatanchors] question about EF Johnson Navigator and CW note transmitted

[Bill Cromwell]

Hi Jim,

There is a keyer tube circuit that sequences the grid block keying to 
the VFO and the buffer and driver stages. That was add-on option during 
part of production (maybe always). All of the Rangers I have seen have 
that option installed. It hangs on the left side of the VFO cage, 
looking at it from the front. We nay be able to see it through the 
ventilation holes in the top of the cabinet so the cabinet might not 
have to be removed.

73,

Bill  KU8H

This guy is an ex-Collins tech and does good repair work on his stuff. But he is not a CW guy so would have no real ear I think for what the Ranger would, could or should  be like on CW.

I put a xtal in it and the xtal transmitted sound is a little more bell-like than the note xtmitted using  the VFO. Not a voltage-sag kind of whoop IMHO, but a noticeable quality difference for Yer Standard CW note.

I also have a EFJ Adventurer that came along quite some time back, from another capable fellow but its been too long to believe the caps should not be looked at before applying juice to it.)

> Part of this query is VFO, perhaps, and other is I expect how  the xmtter works, clamp tube etc, that contribute to the 'sound', I believe, so I guess I am not expecting it to sound modern... I just want it to be acceptable to those out there who have to copy the signal if I answer them and be willing to answer a CQ  from me as well.
