Way to go, John.

Re: [Elecraft] start with straight key or paddles?
Dear John, The best code reader is the one between your ears. At one time it was taught that you had to learn to send on a hand key but in this day of built-in keyers, that probably isn't necessary. I'd use the money you were going to spend on the code reader for a keyer paddle. Good luck learning CW. It's worth the effort. 73, Dave N7AF - Original Message - From: [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Sunday, May 08, 2005 12:55 PM Subject: [Elecraft] start with straight key or paddles? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Alignment and Test Part 2
I am not getting any significant signal input from the antenna and the loss seems to be at D6. In trying to determine whether D6 is at fault, I'm measuring 7.13 volts on the anode and 7.31 volts on the cathode. The manual indicates they should be 8.0 and 7.5 volts respectively. On D7, I'm measuring 7.94 volts on the anode and 7.31 volts on the cathode. The manual indicates 0.0 (error?) and 7.5 volts respectively. Before I blame D6 for the loss of signal, is there something else going on here that may be causing the problem?

Re: [Elecraft] Alignment and Test Part 2
Thanks for the reply, Don. D6 and D7 are oriented properly. I am measuring 7.94 volts on the collector of Q1 and 7.15 volts on the collector of Q2. Anticipating your next question, on Q3 I am measuring: S=0 G=47mV D=51 mV. D should be 8 volts according to the manual.

First check the diode orientation against the Parts Placement Diagram in the rear of your manual, and if these are correct, measure the sources of 8R and 8T at the collectors of Q1 (8T) and Q2 (8R) on the Control Board. If both are near 8 volts at the same time, you have a problem with the controlling circuit in the base of Q1. Let us know what you find and we can proceed from there. 73, Don W3FPR -Original Message- I am not getting any significant signal input from the antenna and the loss seems to be at D6.
