Is the K2 ATU like the ATU in the K3 in that it simply selects values
for 50:50 Ohm rather than physically bypassing? If so, something has

1. BATTERY OPERATION: To conserve battery power, use 5.0 watts or less when

source (including internal batteries). At these levels, the KX3

My arithmetic says $1,000 as kits for the amp and tuner. +$100 factory
built. These kits are so simple, and the components are factory tested,
so it's silly not to take advantage of the discount.

Hi Richard,
It's true that there are lower-cost alternatives to the KXPA100, including
backpack-style 30-50 W amps. The latter would be a good choice if you're
looking for minimum size and weight in an amp.
Many competing 100-W amps don't cover 160-6 meters, or don't make it to 100 W

Regarding Wayne's points. Compared to the KXPA100, the RM Italy 150v (lots

and the IMD performance isn't acceptable unless used in the low power
