Hi Wayne, As -always- thanks so much for listening. This is not a trivial issue for me, it's the "glue" that brings all the other aspects of the transceiver into line. Here's the list in priority order, what I'm looking for in a flexible AGC: 1. Slope - I want S9 CW signals to sound stronger

Wayne, I read your reply to this thread with great consideration. I think your observation that most field testers did not adjust the AGC parameters is a good one. However, I think that that K3--and the Elecraft product line in general--particularly appeals to people who value amateur experiment

We knew we'd get a lot of new feedback on firmware issues once we released the manual. After a huge amount of private e-mail and discussion today over the AGC issue, I've concluded that some of the AGC controls should go back in. They might not be available the instant you get your K3, however

Can the values of all these parameters be uploaded and downloaded from the control port? If so, someone (I wish I could) needs to write a program to do those functions and display them all with the differences from defaults marked. 73, doug Date: Thu, 11 Oct 2007 21:48:36 -0700 From: Vic K

It looks to me as if something like a "system restore" function would be handy, so you could set things back to the last state you had if you decide you have completely messed things up by tweaking. The other suggestion I was going to make was that couldn't some of the more esoteric settings be ad

Maybe some parts of user settings (like discussed AGC "deep params") should be "password protected". For obtaining a password special written disclaimer "not to comply later" will be needed :-) - joking - I understand Wayne quite well, on the other side I know there are very experienced users

I bet it could make a mess of things to make all the settings easy to adjust. I just wonder if the settings are good for AM reception, where you want a slow agc so you don't knock the bass out, and by bass I mean 10 to 50 Hz type stuff. On most 'ham' gear, you don't want that as it would just ad

Since the K3 AM roofing filter is 6KHz, I guess it won't be so hi-fi. It isn't tubes vs transistors, so much as IF coils vs crystal filters. Brings back memories of when I was a kid, when I used to listen to AM radio using a home made crystal set with an OA91 diode, tuned by a permeability tuned c

The problem with scrolling through the menus is that you have to know to look at that parameter. If something gets changed, and you were unaware of it (it happens), being able to see at a glance which parameters were not at the defaults would be most useful. In particular, I'm thinking of the K2
