|Using Anan-10e to drive KPA-500|
Although the KPA-500 is targeted towards those wanting to achieve 500-600 watts out from their Big Rigs, it makes for an excellent way to provide "boots" (a W1FB-ism) for QRP radios that have a 'Key Out' jack.
Here is the chart I made for myself as I continue to consider ordering a KPA-100 - Elecraft's amplifier made specifically for QRP rigs. While the KPA-500 produces a higher output, it is far less portable, especially given that mine is wired for 240 VAC.
The indecision continues...
