Perspective Railpro user has some questions... Signal Range?

RP is fairly tolerant of shorts from my understanding of users experience here, and by that I mean you are not likely to damage an LM if your short protection is up to snuff. One of the members here pretty much tortured an LM while developing his protection and the LM still worked fine. Don't just rely on the LM for short protection though, you really want proper short protection between the power supply and the LM. Ring's PWR-56 would provide this.

That said, tolerant doesn't mean the LM won't be affected by a short that doesn't trip an external-to-the-LM-short-protection-device, The LM will stop and sound will stop playing until the short is removed.

We had a thread not long ago on Atlas snap switches that were causing a problem with RP. The relevant part is from this message that has the video in it: https://rpug.pdc.ca/index.php/topic,964.msg7391.html#msg7391

I have Atlas snap switches. I have found that shorting only occurs on the #6 switches and not on #4's, though I can't explain why. It also depends on the locomotive. Older ones with deep flanges and some 6-axle locos seem more prone to shorting while newer engines pass right through. I am going to try grinding the frogs where the opposite rails almost come together as shown in Dave's video below. As mentioned, the RP power supplies do a good job of protecting the LM modules. I have not burned any up so far.

Can you set a button up to give a a grade crossing signal?
On most of my DCC sound decoders, I can press F9 and get the standard two long, one short, one long horn blast along with the bell and wig-wagging ditch lights. Is that an option with Railpro?
I've been looking at the available literature and haven't come across it.

G8B4Life:
Not off a single button. As you have probably discovered already you can:

Have a horn button.
Have a bell button.

You can also :

Have a flash the ditchlights button and,
Can set the ditchlights to flash automatically when the horn is activated as well.

but they all work independently.

KB02:
So I made a small purchase of two LM’s and the PC Adapter. Figured: Why not? So far I am not seeing why I would not continue a conversion, but one more thing that popped is is the range of the radio signal.

Using the PC adapter, I’m finding I have about a 6 foot effective range. Does that seem about right? Power to the loco is straight from my DCC system, so there is no repeater in play.
