• 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 question. If I put in a repeater TX 152.2775 and Receive 157.5375 will I run into communication problems or reflected power if my antenna is for 152-156? The receive will be a about 1500 MHz out of the antennas range.

NMO's installed, while-u-wait.

Unlikely.
What kind of antenna is it?

The TX is well inside the range of the antenna. The RX side is not as critical and I would not worry about it at all. Likely it'll do just fine and you won't even notice a difference. Usually the antennas have a nice smooth SWR curve, so it's only going to be slightly out of tune on the RX side, and like I said, unlikely to impact performance.

You could go with a wider bandwidth antenna, but I don't think you need to.

I'd not get hung up on it, unless you are using one of those silly low profile soup can antennas.

OK. Thanks for the info. I was going to use the Laird FG1520.

Not related to your question, but I'm guessing you'll be using a duplexer?
