is it 4094 or 4069?

Title and message don't match but can be fixed.

Got it here in AZ, first time I have been able to copy it above the DSL noise. It is weak but solid in my headphones on the Icom IC-R8500 and 60 ft E/W longwire. I can just make out a faint trace of it on the Airspy HF+ Discovery SDR Console waterfall on the SE/NW longwire. 4094.1 KHz 01DEC23 03:03z

I listened here at home but no luck. I logged into the KFS SE kiwi and hear a slow dasher at 4094.100

The 4094.1 dasher runs about 100 mw. So all in all it is a good dx catch when we hear it.

No joy here last night but I am working with one of my rotatable loop antennas that allows me to null out the DSL modem noise quite nicely. I was hearing other low powered signals in the frequency range last night on the loop with the modem in the null so hoping to fine tune this to catch 4094.

With all the xmas lights etc.  catching a 100mw beacon down on 4 MC is challenging.

4094 making it in tonight above an S1 noise floor peaking at over S2 using a homebrew 18" square Litz wire wound loop to null out the local DSL modem noise. The loop is six feet off the ground. A good amount of fading present. Noise floor on the 60 ft longwire is S4-5 and while the signal strength is also higher, the degraded signal to noise ratio degrades 4094 to the point that it is better copy on the loop and at times only present on the loop (two Airspy HF+ Discovery SDRs running simultaneously, one on each antenna). The bidirectional loop null is oriented east/west (very sharp null) with the wide reception lobes to the north/south (very wide). 4094.14 KHz 09DEC23 05:20z
