I just set the audio to be sure I'm  hitting 4 bars of ALC,and the cycle of adjust K-3 power to full expected drive to the KPA-1500 is now more like CW, but the question remains -  after I adjust the power a tiny fraction in either direction, why does the K-3's output power drop way back and re

Re: [Elecraft] Weird K-3 Power Behavior

This is typical for those who insist on not running data modes with 4-5 bars of ALC. You are not providing enough audio and the K3/K3s needs to engage the expander (additional audio gain) in order to achieve enough drive to reach the set power level. 73, ... Joe, W4TV On 4/4/2024 6:21 PM,

[Elecraft] Weird K-3 Power Behavior

I have a K-3 driving a KPA-1500, and have started seeing some strange behavior.  After I adjust the power level control on the K-3,. even a little (like 33 to 31 watts), the driving power delivered to the KPA-1500 starts much below the K-3's indication, and only gradually increases to what woul

Re: [Elecraft] ptt-key

Evert, I am recalling that this is intentional to keep the K3/K3S from being keyed when the computer is powered up after the K3.  IIRC the mechanism is reversed after some action at the computer port. Do a search through the Firmware archives for mention of PTT-KEY to find the answer. 73, Do

I changed the PTT-KEY setting in my K3s (K3+KIO3B) to DTR-RTS, but powering off it returns to OFF-OFF. Can this be stored permanent or am I missing something? 73, Evert PA2KW / 5T2KW / W8S

Timing is everything!  The Earth-facing half of the sun is currently extremely quiet, SFI is around 112, down from nearly 200.  The sun rotates in roughly 28 days [various latitudes do so at somewhat different rates] so try again in about 14-20 days. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn W
