[Johnson] Rangers

[John King]

Sometime in the past, I saw a post regarding how many
Ranger l and Ranger ll transmitters were made, but I
don't know where I saw it. Does anyone have that info
as well as when major mods were incorporated such as
the sequential break in keying circuit? I have one
with the keying circuit and one without it. If I read
the numbers right the 61XXX number doesn't have the
keying circuit, but the 69xxx serial number does. I
can hardly read the 69xxx number, so it may be
incorrect.

Thanks for reading. 73, John, K5PGW
