That Voltwatch is giving you some valuable information. It is telling you that you have one or more of the following problems: To small a capacity battery, a battery with a high internal impedance, a switch that has to high an impedance or to small a gage wiring between the battery and the receiver or a combination of any two or more of these. This is especially important if you are running one of the 2.4GHz units as you are flirting with a reset (brownout) possibility.
Rodney, that was my concern. Even a pcm Rx will go quite for a bit until it reboots. I've got enough room on my bench right now to dig out the techtronic scope and see just how low the voltage does drop at the receiver. Lets see, it's been 30 years since I used a scope for anything useful. I'f Ican just remember. Hope it's like riding a bike.
