41. [CQ-Contest] FT-1000(D) click mod (score: 1)

I haven't looked at an MP yet, but here are the results on a 1000(D)... The problem: Good engineering dictates never running a square rise and fall waveform into a crystal filter. The square rise-and

Hi George, and off at I'm interested in what model HP analyzer you used. What does a unkeyed carrier look like on the spectrum analyzer you used, set to the same level as the radios? What analyzer ar

I forgot to say the resistor goes between the collector and the base of the transistor. The transistor turns on slowly because the 10uF capacitor charges through the 1.5k resistor. The stage turns o

sharp AGC is a problem, but if the radio has overload anywhere before the narrow filter you are in deep trouble with far more than clicks and it would take more than AGC to fix it. The receiver will

Hi All, I certainly believe George when he says this is what his HP141T ( i'm not sure what plug-in he has) measured, but I don't believe the data is actually good because: 1.) The radios I have meas

First this: DJ6RX reports an additional diode to block negative voltage from the transistor was needed in his, but mine seems to not require that. I'm sure either he or I will post something when we

Hi Tom, I just went through that with the FCC. They will NOT allow an external PA even if it "only works with one rig". They were very clear about that with me. It would have to be internal, or face

Without knowing what the person at the other end is doing, and how his S meter works, it is impossible to say why the change is reported as more than the power change Tony. Most S meters are pretty

Hi Larry, Respectfully, the ionosphere is an extremely linear media. If it wasn't, HF would be useless with a mix of all sorts of signals. The signal, if it is below the MUF of a path, is ALWAYS refr

Hi Tony, That is easy to prove Tony, and because it is easy to measure and prove it is also well documented the ionosphere is very linear. The entire purpose of HAARP was an attempt to create non-lin

Did you schedules always start at the same time, or were they random times? Why didn't the local broadcast stations, with megawatts of ERP, keep the path open? 73, Tom W8JI W8JI@contesting.com -- CQ
