RSSI output isn't working as expected? #3

I'm trying to use the RSSI signal on the 2 yellow pins as per this picture: image

I've used my typical cap + resistor filer to turn this into analog for ardupilot (it worked with a regular hawkeye receiver) http://copter.ardupilot.com/wiki/common-rssi-received-signal-strength-indication/ but when I use your receiver, I get about 50% RSSI no matter what.

I have output port 9 set to RSSI, same RSSI that I have on port 3 on my hawkeye and where it works fine. broversityrx

I realize I could break the very nice plastic shield you have around the module to solder the pins that are supposed to switch the RSSI output to analog, but before I do this, I wanted to check with you.

I found out that as shipped the module does not have RSSI working because you need to cut open the nice shrink wrap and solder 2 pads together (I assumed digital RSSI was bridged by default, but turns out nothing is bridged by default, so RSSI on pin 9 will just not work). Those pads are not visible since they are under the paper label that is under the shrink wrap.
