• 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.

Is there any good way to quickly and inexpensively check the wireline output from a tone panel? Can I just plug a old telephone handset into the wireline interface of my tone panel and listen to the received audio or is there some better way to do it without a tone remote?

Lineman's Test Set, AKA "Butt Set", if you don't need to check frequency or level. A standard analog telephone should work fine if you've got one laying around.

If you need to check frequency and level, look for an old "TIMS" set, (Transmission Impairment Measurement Set). You can usually pick them up used on e-Bay pretty cheap.
I carry one of these: https://www.ebay.com/itm/HP-4937A-T...:tV8AAOSwCTBbR8i3:sc:USPSPriority!95076!US!-1

If you are just checking for presence of signal, one of these might work for you.

You could even use a high impedance head phone to bridge the line. Most 'wireline' circuits are 600 ohm impedance, so something like 2000 ohms impedance would bridge the line.

The mentioned butsets have a Bridging switch.

Yes, that will work. But it's not useful for making any measurements. You could simply hear the audio.

...or is there some better way to do it without a tone remote?

A transmission impairment measuring set (TIMS) is what you'd want. Used TIMS of various types are quite affordable from ebay.

The installed base of tone remote systems is still huge. Proper measurements and good discipline of levels is vital to proper operation. Yes, something that can both measure & generate tones is very important.
