Does anyone have an idea about improving the wireless signal for a Sno-Way Pro controller? I bought this new several years ago and it always has given me trouble, “lost signal, no receiver”. I don’t plow a whole lot, but it is quite annoying when you lose the signal in the middle of the street. I’ve experimented some, I just think the blue tooth signal doesn’t work all that well or gets interference from other wireless signals. I’ve cleaned and tested the physical connections with a Power Probe. I know there is a newer version of the controller, but I hesitate spending $400+ for something that may have similar issues. Any suggestions for improving the signal are greatly appreciated. It’s not an issue with the transmitter battery, I keep it charging when in use as well, as the unused time.
