Re: LF: QRSS-60 to the west

Hi Stefan. You are most welcome. :-)

 

On my ARGO display, 700Hz is the CW sidetone "BFO", so whatever frequency I have the radio tuned to should be 700Hz on my ARGO display. Signals on frequencies higher than that should appear above 700Hz, and frequencies lower than that should appear below 700Hz.

 

Here is an example:

In this capture, I had the radio tuned to the USA Lowfer "watering hole" of 185.300kHz. You see station "WM" on approx 700Hz (his ID is a graphical ID that varies in frequency approx 0.5Hz), and his claimed transmit frequency is 185.2995kHz. Above him, at approx 701.6 on the ARGO screen, you see Lowfer beacon "WMS", who runs a straight QRSS60 signal on a claimed frequency of 185.3015 kHz.

 

So, having said that, whatever signal (whether it be a QRSS signal or some sort of QRM) that appears below you on last night's screen capture was on an approx frequency of 136.171kHz. I have no idea who (or what) it is, but it appears to be a QRSS signal to me.

Thank you Doug for the feedback!
Hmm, who could be the other one? I saw VE7SL on the VE2IQ grabber but he was higher in frequency... Or do you use a LSB receiver? :-)

Good copy here in TN, Stefan. Looks like you weren't alone after all, as I see another operator slightly below your signal.

LF,

Again i'm running a lonely beacon tonite at 136.172 kHz (with a small offset of -0.1 Hz) in QRSS-60.
There was rain so a dB is lost but anyway some grabbers over the pond catch the first traces.
Propagation might be a bit better.

73 all and many thanks to all the grabber runners! That a really good service a definitively essential to keep transmitting station (the few) motivated to stay on air.

PS: After further changes on EMC issues in the system i shall come back tomorrow using the IQ converter to generate my VFO signal...
