April 9th, 2018 log... Notice the red bars at the bottom of the logs for this date, April 9th. After getting the GR-216 to log, I left the receiver alone except to save and then switch frequencies. Even though a significant SNR was present, the GR-216 failed to detect and log those values.

April 24th, 2018 partial log ... Due to bugs, the SNR was not displayed on the log for the last 5 minutes or so, but it averaged about 7 dB.

Strangely, my GR-216 displayed a digital bandwidth of 20 kHz ... Bugs and interference probably. However, 20 kHz bandwidth with 16 QAM modulation is the proper way to increase fidelity on shortwave, not the use of 64 QAM modulation.

Interesting conditions continue with much more decoding occurring in April then in December!
