Flex 1500 VAC RX noise issue

I have just started using WSPR 2.0 (WSPR newbie)and have been heard fine over the last couple days.
Receive is a different story. I can get 0dB RX Noise OK and even thought the Water Fall display has received signals I have only been able to decode 2 or 3 station in 48 hours. One unusual thing happens quite regularly. Like every 20 to 20 seconds with the RX Noise. It will be hovering around -2 to 0 dB and then drops to -30 for 1 second then back to 0 for one second then back to -30 for one second and do this 10 or 20 time and then settles back to -2 to 0db for 20-30 seconded then it fluctuates again. It repeats this pattern indefinitely. No mater where I adjust the RX signal it does this. I have a dual P4 3.0 GHz 1.4G Ram so its no slouch. Software is SDR and VAC is 4.10. Kind of frustrating since VAC works great on DigiPan and HRD and others.
