[Elecraft] Re: When do you use fast AGC?

Like Ron AC7AC , as a marine commercial op, I always used the RF gain control (no AGC) when running traffic on ships, but this is a totally different situation for example, if you are in a CW contest when signals in a pile-up vary from barely audible to ear-shattering. Fast AGC is mandatory.

Re: [Elecraft] KX1 receive problem

Don, Thanks for the suggestions. The first thing I did was to remove the 2 toroids and re-tin the leads to be sure they were OK. I keep my soldering station about 700 degrees, so that should have been OK. I will recheck my component placement to see if one is wrong. Sounds like an evening of

RE: [Elecraft] Re: When do you use fast AGC?

I guess I'm the oddball. I run CW on AGC slow 90% of the time. Turning off AGC disables the S-meter and watching the S-meter is part of my enjoyment of the hobby (there, I said it)! If the signal is coming over the north pole and is fluttering rapidly, I'll go to Fast AGC. Using fast AGC

RE: [Elecraft] Re: When do you use fast AGC?

Ha, ha!! Don't feel bad Keith. Watching an S-meter is definitely part of the 'shortwave mystique'. I knew I had arrived when in the 1950s I acquired an HRO-5 that featured a beautiful back-lit S-meter. That receiver required the AGC be turned off in CW mode because the BFO would trigger the AGC

RE: [Elecraft] Re: When do you use fast AGC?

I remember my old SX-96 that had an S-meter that totally dominated the front panel of the receiver. As I recall it went to S9+80 dB or something equally ridiculous. It was also incredibly generous so watching the needle fly back and forth could be very distracting! Doug,W6JD --

Re: [Elecraft] Re: When do you use fast AGC?

Many [very many :-) ] years ago as a coastal marine op, we *always* ran the AF gain wide open and used the RF gain only. As I remember it, the main reason was that with the RF gain up full, there often wasn't enough BFO injection on strong signals in the receivers of that era. It ran up the

RE: [Elecraft] When S-Meters are Useful (WAS: When do you use fast AGC?)

Ron and all, For anyone contemplating connecting an analog S-meter to the K2, A better connection point for the takeoff AGC voltage is Control Board U2 pin 1. That point should have a voltage relating to the signal strength whereas the AGC input into the MC1350 is a current based rather than

[Elecraft] Slow AGC

For the two of us on this list that operate SSB most of the time SLOW AGC is the way to go for relaxed SSB rag chewing. If you're chasing that rare DX with the cans on and the sweat running in your eyes that's another story. 73, Kurt

Re: [Elecraft] When S-Meters are Useful (WAS: When do you use fast AGC?)

All, Is there any way to get the LDG Electronics FT Meter (S, Watt, VDC, ALC, SWR) to work directly with the K2? That would look good mounted in an EC2 box along with a powered speaker and other accessories. 73, Henry - K4TMC ___ Elecraft mailing

[Elecraft] W1 wattmeter accuracy

I asked this before, but didn't get an answer, so I'll try again: does the +/- 0.5 db accuracy of the W1 mean 0.5 db of full scale, or 0.5 db of the reading? So if I am measuring a 5 watt signal, is that 0.5 db of 5 watts or 0.5 db of 14 watts? -- 73, Vic, K2VCO Fresno CA
