The relay appears to be grounded to the mic jack.
The added relay clicks when main switch is moved from stand-by to
phone or to CW position.
The function switch contacts on TX does not appear to be burned.
There is also a on/off switch? added to front panel that appears to be
wired to relay , however, tt has no affect in eather position.
It gets proper grid current but will not load.
It gets no sound in tune position, should a signal be heard in RX set
to same freq, as TX ?
When I first blew fuse due to improper loading, is there a possibility
I also blew a tube that affects ability to load the TX ?
Thanks, Ed, for assisting me with my problems.

Hi, Edward

It could be that someone changed the mic jack to a single-
conductor type, in order to use
a favorite non-push to talk mic he had on hand.
He could then use the transmitter's mode switch
to go from standby to transmit on a.m.,
as if the PTT relay mod was never done.
This would be easily reversed, should he want to go
back to push to talk - no need for him to remove the relay.

Look at the wiring near the mic jack.
Is there a wire which originated
at the PTT relay coil terminated near the mic jack?
It should be shorted to ground
so the PTT relay will be pulled in on a.m. mode.

The connection for the external antenna relay coil is the small
2 pin ceramic socket right above the a.c. power cord,
at the back of the rig. It looks like a crystal socket
for type HC-6/U crystals.

I referred you to the Ranger II manual because I know it spells
out the push to talk mod. The Ranger II is very similar
to the Ranger, it merely adds another multiplier tube to reach
the 6 meter band, and deletes the old 11 meter band.
(The Ranger II also uses different modulator tubes).

You should go over the manual's tuning procedure carefully.
It is easy to damage the final if you transmit too
long without having the final dipped. It's also possible
to damage the final with too much grid drive.

Look over the mode switch carefully. Are any parts of the
switch damaged? It could be that the previous owner added
the relay to substitute for burned out contacts on the mode
switch (not very likely, though).
