Hi Kevin,
I listened for you on 20m but heard, maybe an ESP dit or two. Roy had a big
signal here, S9+ when I moved the beam around to him. Heard a few of the other
check-ins too. Wayne was about S5 and watery with refraction over the hill.
A dinner party took me away for the 5 o'clock
Good Evening,
The onset of fall seems to have helped propagation. I worked a few
stations I had not heard in a while. QSB seemed to be included with
every signal report. I just gave RST as a range. But copy was good
enough that an S1 signal was easy. I only had to turn down one S9
Good evening, All -
I'm putting a post out in hopes of finding one of these fine Elecraft
amplifiers used before I buy new. I'm not in a rush and would like to have
something located by November. It must be in excellent condition and have all
original factory boxes, manuals and cabling.

Hi John,
The acc cable is used to convey the control signal from the sequencer to
the K3 so that the TX INH will inhibit the K3 when configured correctly
and can be used whether or not the band is built in or not. It may be
possible to use the ALC output from the sequencer dependent upon its

Hi John,
Pin 7 of the Acc connector is the transmit inhibit input that is enabled
in the config menu. That is the only way to ensure that the K3 remains
in Rx until the sequencer has completed its cycle. I use this with all
my transverters and LNAs to ensure their correct sequencing.
It is

Some amps have more protection than others. Some have none. :)

I had to revert to WinXP in order to change the port assignment for the FTDI
adapter. After I finally established comms, the firmware loaded and all seems
fine now.
Just wondering why I had the "low gain ratio" error with v1.78?

The KPA500 doesn't work that way so I'd be surprised if the KPA1500 did. For
the KPA500 a badly mismatched load will trip the reflected power fault without
making any change to the ALC

I think I've bricked my KPA1500! Yesterday I installed v1.78 of the firmware.
Today I was calling a dx station on 20m and I kept getting a "low gain ratio"
error message. I thought it might be the new firmware so decided to go back
to v1.64. I downloaded the hex file from Elecraft and somewhere

RIGHT! The ONLY good use of ALC between rig and amp is to protect the
amp from a failure in the antenna system.
Hmmm Do you think!

Hi Don,
Ordinarily, the W6PQL amp’s control board does this via ALC on the exciter.
But, since that is not an option with the K3S, setting TX DELAY on the K3S to
20 milliseconds should do the trick. That is what Jim, W6PQL, suggested I do.
I have been using the W6PQL amp with the K3S without
John,
There is TX Inhibit that will prevent RF from the K3 until that signal
is dropped.
Of course, it requires a signal from the amplifier or sequencer to
indicate that it is ready for RF.
Trying to use ALC for that purpose is not a good idea.
Does the amplifier control the high on ALC, or
Hi John,
Aha! I see that now. OK, I will follow the instruction in Fred’s book to set
this.
Thanks & 73,

Hi Don,
That was timely as I just got off Skype with Jim, W6PQL. He mentioned that the

John,
I do not understand how the amplifier or the ALC could protect the LNA.
I assume the LNA is only used on receive, so if you have good sequencing
between receive and transmit, no damage could occur.
ALC is only applicable to transmit, and Elecraft does not recommend
using ALC to limit the
My apologies - I should have added that I am using a Downeast Microwave DTR
relay to take the LNA out of the line when voltage applied to the relay drops
as a result of transmission.

I am installing an LNA at the feed point of my 6 meter antenna. I also drive a
W6PQL amplifier.
My reading of the manual, and Fred Cady’s book, suggests that no external ALC
is necessary to protect the LNA. Can someone using a similar set-up confirm
this? Or, suggest a procedure to follow
