Hola Manuel A suggestion. Place a dot of white paint on one end of each plug-in rework eliminator and a matching dot on the same end of the receptacle that it plugs in to. This will ensure that you always plug them in the correct way. Good luck and 73 Bob N6WG The Little Station with Attitude

Gentlemen: the signals are here! I had my 160 plug-in Rework Eliminator plugged-in backwards... (my apologies to Gary and Ken!) I had looked at all headers so many times and it never looked wrong to me until Don wrote the word "position" in his message. The good part is, indeed these Rework Eliminators do their job. Now I can go ahead and install all options with no fear. Thank you very much indeed Don, Bob, Jim and José for your words of wisdom and guidance. I woke up this morning, saw your messages, went to the radio, change de the Header's position and my faithful GP gave me a lot of signals, and strong ones too, immediately. What a relief! Because of the header's position shall I do the whole calibration/alignment step-by-step (page 60 to page 64) procedure of PART II all over again? I am also concerned about final adjustments of L34 and L1+L2 as I have to rely on regular noise to do that. No signal generator here. The 7000 khz weak internally-generated signal is there. By the way: my good old childhood friend, José - CT1AOZ, knows my inabilities to deal with components and soldering irons since we were high school kids and he has been very worried about me hi hi Relax Zé...the K2 is coming on with a little help from my friends...Be proud old chap. 73 Manuel LU5OM CT4IK ----- Original Message ----- From: "J ALBU" <[EMAIL PROTECTED]> To: "Manuel Wilches" <[EMAIL PROTECTED]>; <elecraft@mailman.qth.net> Sent: Saturday, February 25, 2006 4:26 AM Subject: Re: [Elecraft] K2 RECEIVER: WHERE ARE THE SIGNALS? > Hi Manuel > > Look and re-look for an > incorrectly placed component (or a component with improper orientation) > this is the most common problem > Now in Portuguese... > Ve os componentes pois o mais frequente é teres trocado a posição > (transistors o contrário ou os diodos). > > Good luck Manel I'm very proud with you my good friend > GOD bless you > > 73 de Jose CT1AOZ > > > ----- Original Message ----- > From: "Manuel Wilches" <[EMAIL PROTECTED]> > To: <elecraft@mailman.qth.net> > Sent: Saturday, February 25, 2006 3:01 AM > Subject: [Elecraft] K2 RECEIVER: WHERE ARE THE SIGNALS? > > >> Greetings from Argentina. >> I am building K2 # 5310 >> I have purchased all Rework Eliminators (they were a breeze to install, >> by the way and are very neat indeed!) and I have all K2 options except 60 >> meters, i.e. 160mtrs - DSP - NB - K2/100 - SSB. >> >> I have completed part II of the RF board and the "Alignment and Test, >> Part II".
