Recorded around the noon hour simultaneously into HP desktop computer using 2 identical $10 XHdata 219 portable AM FM shortwave receivers picked up by 2 identical $7 telephone pickup coils. The 13mhz signal is on the left, the 11mhz signal is on the right. Very bad day for shortwave compared to the usual for this part of the sunspot cycle lately, so signal is noisy and fades, but each frequency often fades in and out at different times. Occasionally both are up at the same time. I used the coils because plugging anything into the headphone jack other than simple headphones makes a mess of reception. It introduces extra noise and an antenna imbalance.
