From the KAT500 manual: "Idle Sleep In some installations a 28004.5 MHz signal may be heard from an oscillator in the KAT500. If this is an issue, you can shut it down when it is not needed. Click on Idle Sleep to put a check in the radio button. The oscillator will stop running shortly after the last key press or the last data communication with other equipment and restart automatically when needed.”
From this, one might presume that’s all the ’sleep’ does - turn off the oscillator and the rest of the circuitry remains live. The spec also says: Supply Current 1.0 A max (200mA typical). I’d assume that the KAT500 would continue to draw around 200mA whilst in standby and turning off the oscillator (sleep) would make very little difference. 73, Alan - G4GNX South Coast UK Elecraft K4D / KPA500 / KAT500 / IC-9700 > On 9 Dec 2023, at 22:23, W2HX <w...@w2hx.com> wrote: > > When I use the KAT Utility to power down the KAT500, anyone know how much > current it consumes in this sleeping mode?
