• 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.

DMR radio project using MMDVM and Orion radios

Hello everyone, I am considering putting up a small homebrew DMR repeater or a hotspot this year and was wondering if I could do it by using switchable Orion/M7100 radios that would be reprogrammed (via .sc file) for amateur 70cm band.

Currently most of the MMDVM compatible radios listed are Motorola brand such as CDM1250, M1125 and some Yeasu radios as well, but as of now I see no technical reason why I could not use Orions as the pinout is fairly straighforward:

1 COS Carrier on sense (squelch)
2 Rx audio Receive audio from radio
3 GND Ground
4 GND Ground
5 Tx audio Send Transmit audio to radio
6 PTT Push to talk (turn on transmitter)

My question is concerning the feature encryption data option, and what does it do exactly.
Will it prevent me from properly receiving/sending data to the radio from the MMDVM board as it senses it is data, or it is something else that I do not know ? The main requirement for radios using MMDVM is that they are 9600bps capable.

Best regards,

Charles VE2FXO

I don't see any issue from a feature standpoint, I would be more worried that the audio path and RF PA might not be up to the challenge. They are great radios with solid design so I'm sure they can probably be adapted to do what you need.
