• 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 am looking at installing a stand alone repeater system for private business use. This is going to be for my own business use so I am treating it as a little research and development as well. My plan is to power the repeater with solar and batteries.

I have done some searching on forums and Google to try and see if anyone has posted anything about the most efficient repeater for power consumption and I have not found anything. Does anyone have any information on this? Ideally I would like to use a repeater that doesn't consume much power while idling. I am looking at commercial grade, 50watt repeaters.

Any thoughts?

Daniels Electronics(Codan) designed to live on mountains with out AC power and operate across a very broad input power range using wet cells(no power generation) or solar/wind.

There is not much that will be more efficient in standby. Really though you want to find an older one, that uses crystals and not PLL/VCO to generate frequency.

Be prepared to pay though, new they are not cheap. You are probably looking at around 7-10k depending on options you need.

Edit: once in a while they do show up on Ebay... For reasonable prices. But if you are looking for new check here: http://www.codanradio.com/lmr/

Most Motorola repeaters are unsuitable as they draw lots of power in standby, unless you buy a used GR1225 at 450 ma. Others are well suited for solar power at 12 to 14 VDC. They are the Codan as noted above, and also the Tait TB7100 at 280 ma; ICOM FR-6000 AT 500 MA like most repeaters, and last using two Ritron DTX-445 modules at less than 28 ma each works. This is a real high spec module with 1.5PPM stability at 460MHz.
