Bonaire SDR Harmonics of PJB

Ai4i

Ai4i

This board has recently got me hunting around for SDRs in interesting places.
I found one in or on Bonaire and decided to listen for harmonics of the all-new...PJB.
Some are stronger than others, some are barely there;
some are clearer than others, some are quite distorted;
some have more or less hum than others, some are almost all hum.
Their primary frequency, 800KHz had by far the best audio.
They were received on every harmonic except for the tenth on 8MHz, up to 29,600KHz just before the receiver cut off.

Many years ago, I aligned an analogue HF receiver by the harmonics of the first station at which I had worked.
It would have been so much easier if WRUF, Gainesville FL had been on 1MHz in lieu of 850KHz.
 
The TWR engineers attenuated 800 on the SDR so it doesn't blow up the whole band (since it's a mile away from the TWR site.). I've had a similar experience picking up the harmonics. That's an interesting receiver-lots of Venezuelans some of which get stateside. Also have picked up Radio Marti, WIOD and WQAM, but not always. (There's a show called "Disco Nights" Saturday nights on a few Venezuelan frequencies
