RE: [Elecraft] Elecraft K2 S/n 01432...LIVES.!!
Another way to look at it is to consider that when you adjust the RF gain manually, the more you need to turn down the gain, the stronger the signal must be. So the S-meter reads higher, reporting that the signal is stronger. The 'automatic gain control' just does automatically what you can also do manually with the RF gain control.

Thanks Tom and Don- It makes sense that relatively speaking as you turn down the RF gain, the signals that still come through must be stronger so I guess the S meter compensates to try to give an accurate idea of the strength. The only other rig I have ever used, the HW-8, has left me ill-prepared for all the goodies that the K2 is about to spoil me with, so most of my questions are pretty basic. Thanks for the guidance! I will definitely re-calibrate my S meter next time the radio is together. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Elecraft K2 S/n 01432...LIVES.!!
That is the main reason I do not use the S meter to give someone a signal report. I leave the AF gain cranked up and use the RF gain to adjust volume. It gives me a better chance at digging folks out of the noise level. Thus the S meter on my rig just gives me a fun light to watch while I am on the air. I should really turn it off but it is much like watching the needles bounce in my antenna tuner. Keeps me company in the shack :) 73, Kevin.

RE: [Elecraft] Elecraft K2 S/n 01432...LIVES.!!
Paul, Andy and all, It is not unusual for the S-meter calibrations to change from those initial settings that were made when you had only the Contol board and the Front Panel boards complete. Now that you have a full receiver, you should re-do the CAL S LO and CAL S-Hi calibration to straighten out the S-meter. The manual does not specifically state it, but those initial settings are at a point where you are becoming accustomed to working with the menu parameters, and may not be the final settings required. Since this question crops up from time to time, it would be a good addition to the manual to put in a step indicating that re-calibration of th S-meter may need to be done after the full receiver is built and all filters aligned. Yes, the S-meter will climb when the RF Gain is lowered - that is normal behavior. 73, Don W3FPR > -Original Message- > > > Still got a couple of problems to sort out,...

Andy, your writing style is very interesting and fun to read and your energy level is inspiring! (and your . key on your keyboard must be tired!) I also have that same S meter issue on my #4818 which is in the middle of its receiver alignment (is it the way it is supposed to be I wonder??) And as I turn down the RF gain, the S meter climbs and climbs until it is all lit up. I don't know if that is the way it is supposed to be or not. But congratulations on getting to hear stuff on 40m! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Elecraft K2 S/n 01432...LIVES.!!
Yes' Sir'ee! You read that correctly...! As of today 23rd April 2005... "... Elecraft K2 S/n 01432.." LIVES..!! Bhoy's... ! You CANT...even begin to know how I feel today...! This, for me, has been only the 3rd most happiest times in my entire life..! The 1st...passing my driving test in 1983, ...first time aroundwith a "hand controlled" car The 2nd Passing my "Ham Ticket"...after 18 months 12 HOURS A DAY...constant studying of the "Manual"...and all other literature involved.. . and the 3rd... " The Birth Of My Elecraft K2 S/n 01432..."...! Oh..! Yes...! . as the man himself Mr Elvis Aron Presley ...sang about many, many a time in my room at home... "I Got My Mojo Working..." And BOY IT FEELS GOOD..!! Now I KNOW...what all the talk has been about on the reflector, HF Bands, magazinesetc for the last 5 years of my life... What a truly "Monumentous" occassion happened here today...! Some of you guy's will remember earlier in the week, where I posted to the reflector... that there had indeed been a "hiccup" in the construction of my "Baby"... ... with the "Alignment & Test Past II" section of the manual, and I was admittedly strugglin' with the "way of the manual", shall we say, ..not knowing wether I was actually doing the correct proceedure for alignment on the 40M Band...(in and around Page 50)... Well... Once Again... my dear friend, "mentor"...and...close friend John Ross GM1BSG...has again (...keep readin' John..!) "Saved The Day"... From the outset of the beginning of the construction of "K2 S/n 01432" (...yeah..I know..its layen in a cupboard t... long..!)... John has been an absolutley monumentally oustanding "rock" for me throughout all of this... the man is a pure genius...a fantastic friend, shoulder to cry on the whole shootin' match... When others all around me, constantly said, "..you'll never do that Andy...your not good enough..." John... helped me "rise above it all"...with his kind words, determination, and sheer bloody-mindedness,... telling me that he "Knew...! that I could do it.." ...I thought he was lying or just sayin that to help me along,...but today, it all fell into place..and now I beleive him...Without HIM...I CAN say, that I would still be "scratching my head" on this one, with the only thing to do "backtrack" through the manual...which we did to a certain extent, but nothing like I would have needed to do on my own if he were'nt here.. Today, we connected up some "Serious" test equipment, I'll leave John to explain the finer points of that and quickly found the "problem"... What Was I Hear Y'all Say...?? In a word ME... Dumb-%^&*...! here had "forgotten" in my wisdom, to include a couple of very important componants during the last few pages before puttin her together for the "Big Smoke Test"...! R39 and another componant...on the back left-hand-side of the "RF Board"...which of course, allowed me to "tune" the various filters, even for 40m...but was stopping the rig from receiving ...ANYTHING !! on 40m... a quick read of the schematic (by John..!) and a scan of the board, brought this to our attentionWhere I "..hastily made a quick retreat to the kitchen...! " ...and I'm NOT joking...!! How "small" once again did I feel for the 2nd time this week.?? Another "small" problem that I seemed to have had, was with some "switching" of the 40m filter,this turned out to be Toroid "T5" or "T6" which I had "orientated" in the wrong direction..! making it act, kinda like a "choke" or "attenuator" (or so john explained..!) this was b.a.d. ... as you can imagine, attenuating, so to speak the signals on 40m... Must have been one of those moments of madness, ...where I had visited other rooms in the house for a moment and forgotten on returning where I was at...or perhaps what I was "partaking in" at the time... I've learned my lesson for sure... But it did "raise a few eyebrows. and ...temperatures..! " I can tell you, when John found out what had happened infact,..he has made sure that I NEVER apply for a job at his satellite business, where they undertake the fabrication of satalite receivers, LMB's etc etc...EVER..!! (...aye John..?) A quick change around of the toroid, a solder of the 2 componants that I had ommited to install... BANG..! There they weresignals 5-5, 5-7, 5-9 ...all on 40m CW..!! Fanfare Plays In The Background...! Oh..! Joyess Moment...! ...and nearly tears of happiness all around SO..! Glad to say that K2 S/n 01432 is now receiving stations on 40m CW...Boy Its Good..!.. Still got a couple of problems to sort out,... Like WHY..the S-Meter is still sitting at S3 of constant... when there is nothing to be heard on the band...or any stations on a particular frequency Suppose I'll come across why later in the manual... perhaps a "tweak" still to be d
