Even in unsettled 40 meter conditions, I'm amazed of the POWER of #QRP CW #MorseCode. The #YouKits #HB1B & #putikeegmini #StraightKey worked through the #QSB #QRN tonight during the @northqrp #NAQCC Sprint #AmateurRadio #HamRadio

Another cool result from my PG&E QRM detector program: it captured the moment the HF radio blackout hit from the energy released by the X9 solar flare yesterday.

The green line is the noise floor on 80m (3.5 MHz) and the red line is 120pps noise generated by our electrical utility.

One interesting tidbit is a momentary blanking at 11:17 AM PDT prior to the major blackout from 12:14 PM through 12:38 PM, which peaked between 12:26 and 12:28 PM, inclusive.

Also interesting is that post-blackout, the noise floor was about 10dB higher than it was prior to it, and remained unsettled for about 9 hours afterward.

My software has detected another solar flare. See the discontinuity in the green line around 9:30 AM Pacific time.

I originally wrote this code to keep tabs on a nearby utility pole which spends half the day arcing and splattering noise all over HF (see the red line), but it also monitors the noise floor (somewhat imperfectly, and for comparison with the utility pole spark-gap transmitter), and detection of solar flares has been an unexpected and amusing side-effect.

Interestingly, the flares themselves quite reliably cause a significant bump followed by chaotic behavior in the noise floor right when they happen. But when the charged particles arrive at our humble planet, they have the opposite effect: the noise floor drops and levels off.
