John Were those traces in the 137.775 area where XDW is running? yes, the three dots at the bottom are on XDW's dot frequency, about 137.7753 Mike ZL4OL
Good copy of XDW last night just before his sunrise. Some letters were readable with 30 second dot setting. Nothing seen of VE7SL. Mike ZL4OL JPEG image
I echo Bob's comments. Andrew ZL2BBJ will be greatly missed for his deep technical knowledge and his generous nature. We will certainly be thinking of Andrew on future Quartz Hill LF operations. DCF3
Just noticed that the unknown station believed to originate in California has stopped modulation and >has a steady carrier on ~135.93KHz. 73 Scott Scott, do you have an accurate frequency for their c
Tonight I see carriers on -5 and +45 Hz relative to 135.93kHz. There is also a strongly audible 50Hz shift RTTY signal centred on 135.95 kHz tonight. Whoops, that's all just the one RTTY signal of co
BTW I see skyway interference on the signal at night and a fairly stable ground wave level during the day... Scott, I will do some daylight searches for that signal. Last time I heard it was pre-Argo
Hello Laurie, well, my receiving setup is simple. I use an IC-R75 receiver with the OCXO option and the 250Hz CW filter. I always have both preamps switched in. The noise blanker is usually off as it
