Benson, I've done some measurements some time ago with my K3 #1212 and i had the following values: K3 power set to 20W, f=7.040MHz 25W 50 Ohms dummy load MCE/Weinschel LP-100A Wattmeter mode USB 1 kHz sine audio at rear line-input, level adjusted to have the desired ALC bar configuration
ALC bar(s) Mesured [W] (avg) 0 8.16 1 blinking 9.4 1steady+1blk 15.95 2steady+1blk 20.72 3steady+1blk 21.2 These values correspond to the above mentioned set-up (K3 #1212 uP rev 2.78) and displayed on the LP-100A with RF head #1143 73 QRO fr Rudolf, HB9ARI Benson wrote: > I do not have the benefit of an external wattmeter at the moment and > frequently use digital modes, esp.
