• 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.

Hey y'all purchased a MTS2000 VHF and it having problems with transmitting tones. In the CPS I will have set a channel to both Receive and Transmit a DPL of 131. It is receiving correctly with a DPL of 131 but its only transmitting a DPL of 023 no matter what DPL I set it to in the CPS. Ideas?

Wrong antenna causing RF to get into radio and distort the DPL TX wave from.
Or the transmitter is OUT of alignment.
Someone jammed in a 'code plug' from a different radio.

And you did check if the software has an INVERT setting for the DPL.

Correct antenna (OEM Moto VHF)
Codeplug possibly although s/n matches (granted doesnt mean it hasnt been changed)
and oddly the INVERT setting seems to have 0 effect checked or unchecked.
So maybe alignment?
Other than that any other possible ideas? and Thanks!

modulation compensation?

Part of Alignment and Calibration.

And we have seen first hand many radios that have the calibration values all messed up.

So, first thing is to look at the TX DPL wave form on a service monitor. I'll bet the TX DPL IS distorted. The TX PL will probably look OK.

One way to determine this would be to probe the DPL signal ahead of the modulator to see if it decodes properly.

If I recall correctly, 023 is one of the normally difficult codes to modulate because of a long string of data with same polarity, maybe that makes it easily susceptible to falling by a distorted signal.
