Gave it a shot but way too much QRM from a local AM station for some reason today.....

Shortwave Broadcast / Re: HAARP Experiments various freq. starting AUG 8
« on: August 14, 2023, 0356 UTC »
location: Central MD.
0350 9.6MHz good reception on the waterfall, audio drifting in and out.
0354 9.6MHz hearing the occasional note.
0406 CW coming in strong on 9.1MHz
0411 no sign of anything on the waterfall around 5.26MHz except someone's radar

SDR - Software Defined Radio / improving bandwidth processing....dual channel afedri & sdrdx on Mac
« on: June 17, 2023, 1917 UTC »
Just picked up a dual channel Afedri (yay me!) BUT i'm running into severe performance problems on my ~2015 imac (4GHz quad core i7 w/ 8Gb). Basically i'm getting a lot of buffer overruns (underruns?) and unintelligible audio decoding with the status display in SDRDX showing -1000 ppm. If I turn off dual channel mode I'm still seeing -1000ppm but the audio decodes fine.
I've tried reducing the bandwidth to 200kHz, dropping the FFT for the waterfall to 4K, and reducing the max display setting to something crazy low (5 updates/s). In comparison I usually run my single channel afedri at 1000kHz bandwidth, with the FFT set at 16k and 50 updates/s.
I think this is a processing issue on the computer and not a network issue as it persists whether or not i'm plugged directly into the radio w/ ethernet or not (vs. having it plugged into an unmanaged switch connected to my other radios).
I know the dual channel radio doubles the amount of data coming in but ironically, I've been able to use the dual channel mode w/ HDSDR (controlling phasing through the Afedri control panel) on an even older (2006!) intel imac running windows, so not sure what's going on w/SDRDX on my mac.
Do i need a super duper computer w/ tons more RAM to get this to work on the mac?

Started with CW transmission...."BEGINNING TRANSMISSION...FOXY? BEGINNING TRANSMISSION" then into music, some fussing about equipment (I think!)
0200 UTC: Station ID
0203 UTC: voiceover
S6...weakish signal, but very audible.

Seems like neither the raspberrysdr nor the fly dog sdr units are available:(. I’m really regretting not getting a kiwi when I had the chance

0218UTC S9 in Central MD with a 12k bandwidth!. Playing around with new SDR software and didn't believe the S9 numbers until I looked at the logs here....
Love the waterfall images.
