For the second time in a week BA7IO has been putting a potent signal into the US on 10 meters. In the mornings. That means long path – 16,400 miles rather than the “short” path’s 8400.
Sure would like to know what he has for an antoona. I also heard BD7NWF but was unable to work him.
Back to BA7IO:
At 10am my local time I came into the shack after cleaning & tightening the connections on my balun (that I wouldn’t have noticed were needed were it not for my recent 160m antenna work) and saw BA7IO spotted by a handful of US ops, none of whom were near me. Doubting I would hear him, I tuned to his freq and heard him fairly clearly. Definitely workable.
The K3’s APF function gets mixed reviews. Indeed, its capabilities seem inconsistent and it’s hit or miss as to whether a given signal will be enhanced or reduced to indecipherable ringing. I don’t know what the variables are that determine which way it slants a given signal but chosen bandwidth doesn’t seem to be one of them.
After working Yang I opened Audacity and made a recording of him calling CQ. Three seconds into the recording, I turned on the K3’s APF. What can I say – when it works, it works!
Have a listen:
About the 160m “T” I posted about previously…weird problem. I can’t get the SWR below 9:1 no matter what. Further, the MFJ259 doesn’t show resonance anywhere. Should be simple – center conductor of Mr. Coax goes to the feedline, shield goes to my ground system. But nada. No trabaja, señores. It does receive from the north on 40 meters though:
For many nights lately, 4S7NE gets spotted on 7001 kHz by other W stations. I can never hear him on my dipole (which is oriented N-S). Last night he was spotted again and, with the dipole/feedline configured as a vertical, I heard him clearly. Couldn’t work him though – bad SWR.
Fun hobby, ain’t it!
