Consistent loss of radio signal

[Lackawanna810]

Hello,

Can anyone clue me in as to why I keep losing radio contact with my locomotives?  My locomotives shudder as if they want to start, and then the radio icon on my HC turns red.

This occurs even after I fully clean the rails and locomotive wheels and am standing less than 2 feet and in direct line with the locos.

Thanks in advance for the due diligence.

Welcome.

You haven't given us a lot to go on. Loss of radio contact is usually from a loss of power (dodgy wiring from the pickups to the LM or quite dirty track and wheels) or it can be from RF interference.

Does the loss of radio contact occur in just one place or all over the place?
Is this small scale (H0) or large scale (LGB)?
Are the LM's mounted the correct way up?

Which way is UP on a LM?

The side with the logo etc. This is the side of the PCB that has the transmitter on it. I only bring it up as it's not impossible that someone, somewhere could hardwire an LM in upside down. Not that it wouldn't work but I suspect it wouldn't work as well as it should; and I do believe I have read somewhere words to the effect of installing the correct  way up.

Now that is something I never realized ?  I usually install with the printed side up in case I want to know exactually is there but didn't know that was a proper way to do it. I have a couple engines that were just a tight fit and had to install everything sideways. Since there were no issues, I lucked out?  Still learning all these years !
