Sorry, but it ran for about 15 minutes, and went to high VSWR. Bad smell coming from the tuning unit -- need daylight to work out there. Off for tonight. John, W1TAG John, W1TAG/WD2XES
One other constraint over here -- during the rare periods that CFH is running on 137.000, weak signal reception would be tough within +/- 300 Hz. John A. Several hundred Hz separation between the W-E
I bury scrap metal in my yard all the time. Does it help? I don't know, but it is metal which should be a better conductor for RF than my sand is in my yard...hi hi ...and you could always sell the h
Beanons...combines the best of gas-powered beaconing and posting... JA ...But what about the Beanons? They sound much more interesting ;-) Cheers, Jim Moritz 73 de M0BMU If possible could all he BEAC
Wrong. Other modes used on both sides of the Atlantic have included WOLF, JASON at various rates, PSK31, PSK08, PSK02, PSK01, GPS-synced BPSK10, WSPR, Hell, and more. My first copy of M0BMU's WOLF si
Dave, I had good luck with the LM2876 at 136 and 185 kHz: http://www.w1tag.com/5watt.htm But it's useless at 500 kHz. John, W1TAG 73 Dave, ZL3FJ No virus found in this incoming message. Checked by AV
Roger, There are many more regulations these days regarding RF exposure, and even the military must pay attention to them, especially when using civilian contractors. Necessary maintenance like tower
Scott, This is almost too funny...I needed to do an 8 kHz sampling rate cal on this laptop, and tuned down to 100 kHz this afternoon around 1800 UTC. The Loran-C signal sounded a bit odd, with slow Q
Roger, Please don't allow my remark to kill any interest in WSPR at 137 kHz! My results with receiving at home have been fine at 500 kHz, and not so fine at 137 kHz. At first I suspected Loran lines,
Roger, Even in an area with very poor ground conductivity (such as mine), environmental losses will be reduced by elevating the lower conductor. I would suggest 2-3 meters as a minimum. In general, l
Another approach is to include a small 12V "telephone" type relay at the input to the amplifier, and powered from the same source. The relay would short the input when de-energized. John, W1TAG I'm c
All, That used to be NAA's regular frequency back in the CW days, if memory serves. They were nicely copyable on an audio amplifier with an RF choke across the input, and a wire (or finger) on the ho
Andy, I used that program when I did my 500 kHz exciter a few years ago. At the time, I went back to some old source material at work, and compared the hand-calculated results with the program. The t

Markus, Nothing seen during that same period tonight. My local noise level is definitely worse at this point. John, W1TAG Thanks again John, Jay and Dexter for your observations! Interesting about th
