• 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.

"Sonar" brand radio help

I've got a couple of "Sonar" FM2112 mobile radios. Have had them for about 15 years. Got them at an auction. As purchased, only one channel had a frequency programmed - 157.680. At that time - pre~internet- I called the company listed on the paperwork that came with the radios and got a price sheet from them. Among other things you could have a prom programmed to your specs and shipped to you to install yourself.

They are 16 channel scanning radios- programmable via EPROM. I just recently dug them and the paperwork out. Went to call Sonar and see about having a prom made. I was just going to use them as scanners. I got them cheap and there aren't enough frequencies around here to fill the prom up. Should be just the ticket.

Sonar says they are out of business- as far as these radios are concerned. Nothing noteworthy on the internet about them and absolutely nothing on the radios. They said the sold all their remaining proms and the programming stuff to a place up in the Northeast called Bardwell Electronics about 5 years ago.

I googled that and came up with a number, and as of 10 minutes ago no one answered there.

If it comes out that they can't/won't program a prom for me, am I dead in the water? Where should I turn my search efforts if that is a dead end? I was hoping someone out there in the ether would be able to steer me in the right direction.

They are real nice looking radios. The previous owners had a sheet metal working shop and this was the owners and his wifes vehicle radios. Not a scratch on them.
All the company's radios sold in one box I bought. 3 of them were these huge G.E. trunk mount, crystal controlled monsters listed as 80 watt output. Back then I connected them to a power supply and an antenna and they did transmit to each other. They are long gone, but I saved all the smaller, solid state radios. These 2 Sonars, and 3 or 4 "Standard" brand 2 channel crystal types.
