• 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 recently bought a pair of radioddity R2 radios because they had the option to turn on a scramble feature, and I wanted to fiddle around with it. I downloaded the software program for the R2 radio. It's a 16 channel radio and along the top are RX, DEC, TX, ENC, Scan Add, Wide/Narrow, TX Power, Busy Lock, Scramble, and Compander.

I understand everything and how it all works except for the Compander. It has a simple Yes/No option menu and all 16 channels are set to No by default. I have never heard of the term "Compander" before and we wondering if anyone knows what it is and what it does? Thanks in advance.

Compander means compressor/expander. It compresses the transmit audio and expands the receive audio.

See https://en.wikipedia.org/wiki/Companding and https://en.wikipedia.org/wiki/Dynamic_range_compression
