• 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.

Hi I am "planning" to build my budget repeater system.
Here is my list of materials

2 pcs Baofeng BF-F8+ for TX/RX with battery eliminator
1 pc Diamond X50 Antenna
1 pc regulated PSU 12V/10A
1 pc 30W Duplexer / Repeater

I am on a tight budget
Please free to comment and give advise

I was goig to do the same but then picked up two GR-1225 repeaters, one with duplexer for $325 and one without for $250. Because I use them at work too I already have the software and cables to program too.

What's the actual budget? What's the purpose of the repeater? What frequency? What are you using as a controller? Where will it be deployed?

Without defining goals for a repeater, it's difficult to go back and say whether it was successful or not. That said, using a pair of Baofeng portable radios for the transmitter and receiver of a repeater is a recipe for failure.

BAOFENG SAYS THAT WILL WORK. For how long, that is a question that all of us want to know. Thinking quality and dureablity by the price, most of us have reservations that radios that cost so little will hold up. I have yaesus, kenwoods, and Baofengs. I have had no problems with the Baofengs, they have held up, easy to program and inexpensive compared to other radios.. If thje "experiment fails, the componets will be useable again. I don't see a controller, something that id's and switchs the radios from transmit to receive. Baofeng has those starting at $24.00. I am not sure they have an id'er. The radios should hold up though the transmit radio will be going for longer periods of time as compared to an individual using the radio. If you are going with a vertical antenna separation, you don't needf a cavity, but a single antenna, you will need a cavity. I would think $300 or higher for a set of cavities. Then you will have coax. Todays prices an investiment in copper. I expect a Baofengaccountant will some day run to the head office and say, "we are missing a decimal place, the radio should cost this much"..

Yup it will work. There are a few youtube vids of people doing it. One radio recieves and the other retransmit on the offset. All you need is the 3.5 to 2.5 cable. You can even do it without the cable but audio wouldnt be as good.

Yeah it will work.... until the finals are burnt out of the handheld radio that transmits. Handheld radios are not designed for the amount of duty cycle that a repeater has, unless it's barely used. Plus the limited power output of the handheld will not get a whole lot of range, unless you're going for short range anyway.

What about station ID? Not sure if this is for Amateur Radio or some other kind of use, but the "repeater" needs to have a way to ID itself with a legal call sign.

It will work in theory and be a good experiment, but don't expect this thing to be a permanent repeater with a large coverage area.
