Jim, and All, The end question I was looking at is this: My antenna current measures 2.8 Amps. If I remember correctly, this was calculated or estimated by folks in the group to be the expected curre
Jim, Whew! That takes the pressure off. Thanks for the help. I was beginning to get worried about getting this right and the more stressed I get the lower my brain function is and the more I have to
John, and All, How do I measrure the impedance? Does this mean that I build a bridge of some kind and feed it with low power RF from the transmitter? Is there a way to calculate it by taking readings
Bryce, Scott, and other grabber ops, Watching propagation is a much easier task due to the work which you put into keeping the grabbers up. I, for one, would like to thank you publicly for your effor
J.B., and Folks, J.B., If you capture VY1JA, you will have the station farthest east to have done so. If you even get a ghost with holes in it, I can send you an Argo of what was transmitted to compa
Wolf, The (receive) calibration settings for Argo look like this: Measured frequency: 391.78 Displayed frequency 400.00 Frequency Offset 137380 This makes the display and sidebars of Argo match my re
Scott, Special thanks to you for keeping that grabber going even through hideous QRM. Your work was the evidence needed to prove connection between Harmut's captured UNID and its source. The efforts
Mike. Winter weather is like propagation... Very changable. During the winter we often have, "Chinooks" which are warm winds off the sea as far as a couple of hundred miles inland, driving the temper
It is 1350 local at both VY1JA and VE7TIL and VY1JA is on his grabber at about 1000 miles distance and 1W erp. http://www3.telus.net/sthed/argo/ The signal is weak but there on the left end of the ca
Mike, -I use a heatgun to get those cores out without breaking them. OK too late for the sign at the top of the cliff... I am now in need of the ambulance down in the valley. J.
Steve, 1200W out and the rain is sizzling on the coil... silly boy...won't you ever learn? Natural coil cooling.... friendly to the enviroment, efficient and free. Hmmm. J.
Hello Wolf, Thanks for your offer of help! I can offset the VFO to accommodate most anything within the SSB bandpass, but how is this? 1000 Hz = dit 1020 Hz = dah I use USB mode setting and then add
Hello again, All, Spectrum Lab apparently will have a very large learning curve toward success for me. Success means to use the software to key the PTT on the RTS line for DFCW transmissions, and to
Hi Andy, Slight Saturation in the core causing a loss in inductance at high power perhaps? No, the tests were performed with the same transmitter at the same tap and power output through the same coa
