Is there any way for you to add more lengths of wire from the ground rods around the base? Believe me, you can’t get enough ground radials for that antenna. The more I added, (around 75′ in length) the better results I got with the tuning.
I also had an issue with the audio cables. Unhook them from the xmtr and check your test point voltage again. If it is closer to the desired 15 volts, you DO need more ground radial area around the base.
