Although the RF signal was ≥ 60dBuV the SNR was low and the decoding erratic. ~83% CDA.

The RF signal was stable 60-70dBuV but with low SNR and erratic decoding, two TX breakdowns noticed, ~46% CDA.

Although the signal is around 70dBuV the decoding was very bad. I stopped of logging.

Why did the number of successfully decoded frame vary in zigzag like fashion? Local interference?

-1. No local QRM.
-2. About 10 dB fading. When the RF signal drops down to ~60dBuV decoding stops.
-3. Very low SNR, usual for this TX.
-4. My area inside side lobes.
-5. Bad IR.
-6. Of course, the high BR...
