• 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 have a couple of GD-77 radios and they do work DMR Ok for my use. The only thing that I don't like about these is that there isn't a way to externally power them.

Actually all I really need to do is charge the battery when away from commercial power. I have a solar battery power unit that outputs a clean 13.5v. It also has a 120v inverter. I suppose I could plug the GD-77's charger wall wart into the 120v inverter port, but I'll end up wasting a good amount of power using the inverter.

The original charger base wall wart has a labeled output of 12.5v DC (no current listed).

Does anyone know if the charger base itself has any type of charging regulator in it ?

I am thinking I could just take the 13.5v out of my solar power bank and plug it directly into the base but I only want to do this if there's regulator/over-charge shutoff of some type inside the base.

Thanks!
