Yeah...I may use a relay. The TX PL EN wasn't the thing I needed. However,
the "green wire" was it. (Thanks Juan) I figure it's not a big deal to
short it out because it's the wiper of a 47K pot, not the direct output of
an amp. I tried it this evening and it works. The signal level was about
170 mV nominal. Now, I have to switch it with COR which is available in
that module too. So, I'm thinking I'll use a reed relay to do the job. It
should be quick enough. What's good about it is the regular PL works as
advertised while DPL can be switched on with COR. So the plan is to link
with DPL and let the repeater do it's regular thing with PL.
Thanks Skipp.

I vote for the relay spdt or dpdt method... even using a 4.7k
resistor as a termination. Maybe not in this case... but
it's not always wise to ground an (audio) amplifier output. A
220pf disc cap over the 4.7k load resistor keep stray rf under
control.
