Moved InAir 36/45MHz WFS from ISCT6 to ISCT1

Corey, Daniel, Stefan

We moved one of the two AS56/45 WFS from the AS port in-air table (ISCT6) to the REFL port in-air table (ISCT1). (Serial number S1300512)

The WFS was connected to the RF cables for the REFLAIR B WFS, and powered by the third slot on the WFS interface chassis.

 

One thing to note (again) is that those 5-channel RF connetors are impossible to plug in - in fact the only way to guarantee that all connecions are good is to remove both the connector backshell and the WFS box cover, and idividually checking that every channel pin and shield makes a good contact. Corey has some pictures of this.

 

Also, we quickly wanted to check the RF transfer functions from test in to each channel, but they looked broken. The chain definitely needs to be checked out again.

As Stefan notes, the "connectors" for the WFS were a bear to work with.  Since the pins would move, and you never knew if the connector was really connected, Stefan removed the covers to the connectors, and also removed the back panel of the WFS to make sure the connector is connected.  He did this on both. 

To remove the connectors, one will need to remove the connector covers, and then disconnect the connectors (not ideal, we know).

Attached are photos of the connectors connected (with WFS panel removed and connector covers removed).
