It sounds like you did it right - there's not much to screw up. Maybe the
Ranger has a problem. I get about 12W out from that connection. My Ranger
power supply is not stock, but the voltages are pretty close. However, 15W
is what I hear reported from others who have done this.
It helps to reduce the grid drive a bit in the low power mode - adjust the
drive pot for maximum RF out of the Ranger - but it won't make the
difference between 5W and 12W out.
And you should have absolutely no problem modulating to 100% positive and
beyond if your audio is phased correctly and the modulator is working
correctly; especially using the low power mod where you should have plenty
of audio power to spare.
How much RF carrier do you get out of the Ranger when operating normally,
and are you able to modulate 100% then?
