[Elecraft] KPA1500 Using Multiple Antennas With the Tuner

[Dick Dievendorff]

Your K3 stores the power settings. The amp reports when it goes in and out of OPER and the K3 (and K4) store two power settings per band, one for the amp in STBY, another for amp in OPER. You adjust these levels at the exciter, and they’re retained for recall on band switch and power off/on. Mine are typically 100w for amp in STBY and 25-35w for amp in OPER. I’m primarily a CW guy, but in digital modes I often drop down to see who I can reach with good antennas and little power.

There are K3 and K4 menu choices for “Per band power” to enable this.
