Took a trip out to McKinney Falls State Park here in Austin, TX a few days ago during lunch to do some mobile HF operating with my SDRplay. I’ve always been interested in operating my SDR from a quiet & remote location. A state park was as close to that scenario that I could get, lol. You have to imagine that living in the 11th largest city in the United States, I’m bound to run into some RFI here and there. It occurs in the weirdest of spots too. Occasionally i’ll drive around with my HF rig on in Austin and especially in an urban environment, i’ll experience all kinds of interference, most commonly I experience it close to businesses & structures.
I scored a contact with W6VAH, the VA hospital out in Loma Linda, California, they hold a regular net on 20 meters, so snagged them on 14.258. Snagged a few others on 20 meters, but the bands as of late have been extremely noisy.
Speaking of noise… i’m currently considering investing in an active magnetic loop antenna for the home shack. I figured being in the HOA where I’m at, and my inability to get a full size dipole up in a flat top configuration, an active mag loop might help since its independent of ground, and it has the ability to null out interference. Usually if it’s interference that I’m experiencing, it’s coming from a nearby neighbor or company. I’ve tried regular transmitting mag loops before, and to be honest I wasn’t particularly impressed, but one that’s preamplified? I’m wondering if one is worth a try. They’re not cheap either… The Pixel loop from DXE is almost 500 bucks, the Wellbrook loop is just a tad less around $460 shipped from England. More to consider regarding my home QTH antennas! I refuse to give in to the QRM! Anyone with experience with these two antennas?
