• 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 have a spectra radio, 110W UHF, and I recently bought a siren speaker and a PA with some cables included. I have never used the siren speaker in the past so I have no idea how it works and how to connect the radio, the PA, and DEK, and my speaker, I am here seeking help from those of you who are knowledgable and experienced, I believe I have the cables connecting the radio and the control head, the cable connecting the PA box and the radio, the short cable connecting the DEK and ??? but I really couldn't figure out how these gadgets can be connected together to allow use of the siren PA through the speaker, many thanks and happy holidays!

-DEK cable to the control head (small connector on the DEK)
-Siren/PA cable from the RF deck (connector inside the handle) to the Siren/PA

Then go in the RSS and enable features as appropriate/legal and change the key assignments to match the DEK.

I'd like to thank N5IMS and Stateboy who generaously provided guidance here, I was able to hook up and try for the first time. Here is the result, I connected the Control head and and radio with the cable running from left of the handle where there was a DB25 connector to the back of the control head where the other end of the control cable clipped in position, another cable running from the PA unit to the other DB25 connector just below the handle of the radio, I also connected the control head and the DEK with the small connector cable (same connector at both ends), I run the power cable from the power supply to the radio just above the DB25 connector, and I also ran the red/black power cable from the PA control cable, lastly I connected the speaker cable to the speaker (the dual wires running from the PA control cable) and as I was trying to connect the second wire, after securing the first wire, to the terminal on the speaker connector, then i heard this loud noise almost as loud as a firecracker, I was scared big way but as nothing really happened except the noise, I tried switched the wires and attempted to connect for the second time, same thing happened when a strange loud noise, this was when I stopped and decided to get your inputs and further guidance.

I don't know what happened to my connection which caused the problem, and I certainly need further help on the right connection, many thanks again.
