[TenTec] Orion 2 Noise Blanker Question

[jon greenwood]

I have 2 Orion's 565 and 566. Both have the latest firmware updates V3. The 566 has the rx366 sub rx. The Orion has the standard sub rx. The Hardware noise blanker on the Orion works great. On the Orion 2 when the hardware noise blanker is on it messes up the rx in the main. Strong nearby signals even 20k away can modulate noise. I have read up on this in the Yahoo group and seems like it may have been due to the latest firmware update. Others comments seem to indicate that not to be true. One thing I notice is the RX on the Orion2 seems to be very strong. The sweep function is almost useless as everything reads high across the "bandscope" On my Orion the sweep is much lower even to the point of being lower than one would think it should be but the signals then are well above the noise and easy to pick out. It is almost like the rx in the Orion 2 is to "hot" thus causing the noise blanker issue. Same antenna's same settings etc. 

Is anyone aware of an alignment procedure to adjust or set the receive signal strength in the Orion2? That would be my only gripe on these great rigs is the lack of a good service manual. Or any other thoughts on a trouble shooting path.
