• 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.

Wireless alerting system ideas. Ideas needed.

Maybe i'm overthinking this. Maybe i'm just shooting in the wrong direction.

I have a float switch (N/O) contact that needs monitored from about 400 yards away. When the contact closes I need to alert people in a building about 400 yards away with a light an buzzer/ bell.

What are your thoughts on this?

TIA,
Dave

Look at some of the SCADA devices that work together without supervision that employ I/O with an integrated radio.

There are a number of products that take a contact closure at one end and replicate that on the other.

You would want likely something that can be set to a default state of your choosing if communications are disrupted due to interference or power loss at one end.

One example:

If you're in an environment that can tolerate a loud alarm and/or flashing light, that seems like a simple solution. If you're in a residential area, you're bound to tick off the neighbors. One of our sites at work is down the street from the local water treatment plant. I hear such alarms going off from time to time. The distance is probably 400yds. Granted, I may not hear it unless I'm outside. As a proponent of the K.I.S.S. principle, I see nothing wrong with the loud alarm if the conditions are appropriate.
