And furthermore: The ARRL cannot even find space on their W1AW schedule web page for the UTC times, even though there is a lot of blank space on that page. ___________________________________________

There was a discussion about the relative speeds of circuit breakers versus fuses on this reflector some time ago. I stated that my gut feeling was that fuses might very well be much quicker respond

Hi all, My Omni VI has a cyclical drift problem. It sounds like a PLL drifting away from lock and then being pulled back into lock over and over again. My first guess was that one of the crystals or

Hi Clark, Thanks for the suggestion. I don't hear the 20 MHz TCXO drifting. It is rock solid. Maybe if it's output level drops this problem can occur while the frequency remains stable??? DE N6KB ___

Adjusting C31, the 20 MHz oscillator trimmer, seems to have fixed it. I don't understand why, since even if it were slightly off frequency I would expect the band select xtal oscillators to be locked

Not used for at least 10 years, and the capacitors are certainly a lot older than that. When you compare the cost and labor of buying new ones and putting them in first, versus the cost and labor of

Hi Mike, Well, there are many possible explanations (at least as many explanations as there are circuit stages between the antenna port and the audio output) for one rig to be noisier than the other.

An alternate method of blowing up the bias board it to put exciter power to the 425 with no load on the output, even with the 425 in standby or not even powered up. The easiest way to do this is to u

This is sort of my experience too. I do use the model 221 six pole 250 Hz filter in the 9 MHz IF a lot. However the model 282 in the 6.3 MHz IF never gets used . Using the 250 Hz 8 pole filter "inte

Hi Mark, This contradicts my experience, when by "a noisy band" you mean atmospheric noise. It may be true if by a "noisy band" you mean a crowded band. I regularly work a station when there are thre

True, the PBT works in the 6.3 MHz IF. If the signals coming through the narrow 9 MHz IF filter are not also passing through the narrow 6.3 MHz IF you won't hear them. So the PBT has to be adjusted
