On 160 and 80 meters, the KPA1500 ATU has 10 kHz "step size" between "bins".
Consider tuning at 3505, 3515, 3525, 3535, 3545.... thru 3995. There's a table on page 52 of the KPA1500 owner's manual that lists the suggested tuning frequencies on all bands. 73 de Dick, K6KR -----Original Message----- From: [email protected] <[email protected]> On Behalf Of [email protected] Sent: Tuesday, December 10, 2019 15:04 To: [email protected] Subject: [Elecraft] KPA-1500 ATU operation After saving my KPA-1500 ATU impedance matching parameters on 80M at 20 Kc intervals (3.510, 3.530, 3.550, 3.570, etc, etc), I expected that the KPA-1500 ATU would automatically switch to the next set of L/C values at the midpoint of the 20 Kc segments (like 3.520, 3.540, 3.560, etc, etc), but I find that it switches randomly, sometimes just 2 Kc away from the main tuning frequencies. Does anyone have information on how the ATU is supposed to work when it is polling the xcvr for frequency?
