QRS CW

Thursday on the deck with 3W T1380. A few notes: John/K9KEU is using a rebuilt "Micamold" transmitter circa 1948 about 20W output (mod for DDS VFO control). Near the end of the video at about 27 minutes you can hear the difference in Harry/N9CQX signal as he adjusts his output power from 10W down to 3.5W and then back up to 10W. Harry's antenna is a 125' dipole 50' high with 450 ladder line to EFJ matchbox. There are a few examples of QRM (man-made interference) in the video. One is not RF, it is ambient level noise from a garbage truck around minute 20 of the video. There is also a tuner-upper on frequency who Harry invites to join us without success. There is some QRM in the video from line noise and consumer appliance but generally not too bad and the signal to noise ratio is sufficient for the entire chat which lasted for about an hour and 10 minutes (only the the first half hour is recorded here.) The propagation is all NVIS E/F1layer and at the very end of the video you can hear D-layer absorption building with the associated solar generated QRN.
