Any Info at all ?

Is the radio intended for amateur radio? If not, since this group is for amateur
radio, those who have this radio may not be members of this group.

My guess is that you might be converting it for amateur radio use, maybe for the
900 MHz band (?), but again, the right audience may not be here for your
question.

I wish I could help but I'm more familiar with repairing older radio equipment
and tube radios. You definitely won't get much help in the JohnsonRadios group
on groups.io because their description says, "If it has Johnson on it, has
tubes, then you are in the right group."

I searched through all the publicly listed groups on groups.io for one that
might be useful to you but all the others deal with the tube radios, families
named Johnson, radios from Watkins Johnson (I assume it was either after a
merger with EF Johnson and Watkins or they broke up the company and spun off EF
Johnson), a Johnson HS PTA group, but nothing helpful along the lines of what
you're in need of.

If the programming software was protected under copyright, no one might reply if
they did have it because of groups.io policies regarding that type of
information. (They have even closed down groups that share copyrighted
stationery, I assume for use in MS Outlook's email program.)

All I can do is refer you to the company, which you probably already have:



Also, if you plan to shift the covered frequencies up to the 900 MHz Amateur
band, you may have to modify the passband filter (or low pass filter) to get
much of a signal there. They probably have such in there to take care of
spurious emissions from the transmitted signal.

I hope you find what you're looking for. I think you will have to purchase the
programming software from the company. I can tell you that RT Systems, which
makes programming software for many amateur radios, does not have anything
listed under Johnson or EF Johnson.
