[Elecraft] KXPA100 Hi PA current ?

[WA7SPY]

Hi Don,
Thank you for the information and input about OCF antennas. I did a measurement of the supply voltage to the KXPA100. here is what I Measure with my Fluke 77 meter:

The voltage measurement was taken at the supply power plug from the amp that plugs into the KX3 to power it. I have the internal batteries installed in the KX3 so doing the test was easy. I am using an Alinco DM-330 MVP power supply with a very short cable run the the KXPA100. The supply voltage reads 15.1 volts without the amp or KX3 transmitting. With the power setting on the KX3 set to max 110 watts. When the KX3 is keyed and the amp is active I measure 14.6 volts. The voltage drop is not that big in my opinion.

I have a 10 foot ground round sunk all the way down with a heavy braided cable less than a 6 foot run to a 1/4 inch thick brass 8x8 inch plate. I then have braided jumpers going to the KX3 and KXPA100 less than 8 inches from the brass plate to my equipment.

What else should I do or look for? I have to say my Carolina Windom performs extremely well!

Thank you,
Glenn WA7SPY
