I have completed #4554, which consists of the K-2, noise blanker, DSP2 unit, 160 meter, 60 meter and SSB modules.
I bought a used Bird wattmeter through Ebay, which was finally delivered yesterday. Last night I went thoroughly through all of the alignment and test procedures. I did not have a signal generator, so I used on-air signals from the antenna, which is an acceptable multiband dipole mounted ten feet above the roof of my home, fed by coax. I then peaked all bands properly using the Bird and a dummy load. Everything tested out well and all of the transmit power tests worked fine on all bands using CW. I have been able to generate power at or above 10 watts on all bands. All other modules have also checked out fine. The DSP unit works exactly as specified, and I have set all of the filter settings according to the recommendation in the SSB manual. The last tests I sought to run involved SSB transmission. I have not completed those tests as I did not yet have a separate receiver set up to check on the quality of broadcast. I plan to tackle that tonight. By the way, I bought a new Heil MD 2 configured to Elecraft standards, and I installed all eight pins and the resistor. I did check the transmit function at 5 watts into the Bird and a dummy load. I checked it on all bands. I found that on some bands the meter would peak right at 5 watts when the PTT switch was pushed on the mike. However, on some of the bands the watt meter would barely register, or else it would register at a reading below 2 watts. Is there a problem here, or is this normal? If it is not normal, what circuits are likely to be suspect? I am not an electronics expert. At what point in the circuit flow does the SSB transmit signal become frequency band-dependent. Thanks for your feedback. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list. Subscriber Info (Addr.
