I have two transponders and tried the second one and had the same result.
Both transponders have been tested in ch1, ch3 & ch4 and still no light.
If I plug a 6V battery into the receiver it all works fine.
The servo also works fine from the power supplied by the BD.
It would seem that the AMB transponder needs more voltage to function than the servo and for some reason the BD is no longer able to supply this.
Some of you are going to say run a booster or a receiver battery etc however, I don't understand why it's been working and all of a sudden stopped working.
I have never adjusted any of the settings within the BD since the day I first ran it so I'm stumped on what the problem could be.
If anybody has any suggestions I would really like to hear from you?
I've been trying to remember what the minimum voltage is for the original AMB transponders.
You might want to consider getting an MRT clone of your PT which can work at much lower voltages.
Is running a receiver pack of some sort out of the question?
