Re: [Elecraft] Power hunting

Exactly right, Joe. AND, the crystal filters in the K3 are not ideal. Soon after I started running RTTY with my K3s in 2008, I saw incidental AM resulting from the ripple in the stock 2.7 kHz 5-pole filter. When I replaced it with a 2.8 kHz 8-pole filter, which is flatter, but still not

Unlike many other digital modes, FT8 is a constant carrier, constant envelope mode. The ALC level will quickly settle at a constant value and should not hunt. ALC does not affect FT8 transmissions. My K4 goes to 5 and never changes and peak power on an external analog meter does not change.

Hi, I did mean ALC, and the voltage is not moving at all. Sits at 14.1. 73s and thanks, Dave NK7Z http://www.nk7z.net On 12/23/2016 06:52 PM, Nr4c wrote: AGC just flashing? Do you mean ALC? Look at voltage while transmitting. Sent from my iPhone ...nr4c. bill On Dec 23, 2016, at 5:02

[Elecraft] Power Hunting...

Hi, I am sure I saw a few things a while ago on the K3 power hunting when running JT65... Does anyone know what the dates were for those posts? I can search the archive... My K3 hunts power levels when running WSJT-X, and I have the fifth bar in the AGC just flashing... It still hunts...
