NCE –
Why does the horn not switch off after releasing the button when using Radio?
Nick,
Unfortunately
you can't fix this by changing the number of horn off packets.
Bill
is right; the problem is due to the radio.
The
Horn button works differently than the rest of the keys as commands are sent
each time the state of the key is changed.
When you press the Horn button, two "horn key on" commands are
sent to the command station, and likewise two "horn key off" commands
are sent when the key is released.
If
these packets get dropped or corrupted due to a radio path null, then the
command station never sees the key change state. Hence you can end up with the horn stuck on,
or you can be holding down the horn key and the horn will not sound.
The
horn off packets that Bill referred to has to do with the number of packets
sent to the decoder from the command station.
The problem is not between the command station and the decoder, but
rather the command station never sees the "horn off" command from the
cab.
The
cheap and dirty workaround is simply to press and release the horn button quickly
one more time and this will send another set of horn off commands when the key
is released.
Normally
I would recommend the RB02 and the RPT1 to improve the perfomance
of the radio link as this usually takes care of this problem. But you are already running the repeater
system, if you are still seeing holes in the radio coverage you may want to try
and add additional repeaters to improve things.
How
big is your layout room and how much area does each
radio base station cover now?
I
hope this helps,

Nick, this is a problem with the NCE radios and some other systems
also. The horn
button is an on/off momentary button which differs from the F2 horn button
which is an on or off button each time you press it.

The problem is the radio sometimes doesn't "see" the off code when
the button is released.
This can probably be cured by altering the number of "off"
information packets (code) of the specific button that the transmitter sends to
the receiver. Unfortunately, I don't know how to do that. You might call Larry or Jim at NCE to see if
it can be done.

I hit the Horn button and the horn stops after I left off the pressure
on the button.
