• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

I can definitely see where this can be a huge problem. I noticed that 132.5 KHz is a common powerline communications (PLC) frequency. I don't know if that use extends beyond domestic household products, but even so, in urban areas, homes may be tens of feet from the right of way.

Thank you for the link, i am really interested in this as all wagons are couple via connection cables.. these DC connections can be loose and may indeed also cause arc flash, which result in the ARC noise they are talking about..

It is also an aspect i had not considered for DC based PLC - now i need to investigate that as well.

Hi All,
I am new to this forum and, although trained as a radio fitter mechanic, it has been decades since I delved into anything radio-related.
Welcome to RR (not rail road) and thanks for bringing this up, it's been very informative. I talked to a tech a few weeks ago about the electronics in the rusted metal hut by a local yard arm crossing, interesting to see the technology used to gauge the train speeds to know when to lower the arm.

His partner must have been a new hire, only knew which way choo choo go, muttering about being a pawn in the game of life.
