• 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.

If im using correct abbreviations?

Last nigh had a late appointment and near a warehouse district, not sure if was timing or this how TRBO works.

Mostly getting one sided conversation on 468.5750 DPL311 of course like normal search enthusiast I plugged in 463.5750 but could only hear the TRBO type noise.

Checked the FCC Data base but its possible being a lease radio so who heck knows.

Just curious when units transmit on the TX side is the transmission in the clear or some sort of garbled transmission? Never really close to any of them in use to play around except at the race track and know you can be TRBO on simplex.

Trying learn more about this system, if need re-direct this please do so.
Thanks
Steve

I apologize. I meant, is it Digital sounding or TRBO sounding. There is a difference. Check that link out and see if you can pin it down better.

I'm guessing the other side of the conversation was P25 digital and not TRBO.

"getting one sided conversation on 468.5750 DPL311" The dumb s---- so-called Frequency Coordinators assign the repeater inputs to simplex users.

When you ask for two simplex frequencies you almost ALWAYS get a pair. Comes in handy later when your customer wants to add a repeater.
