• 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.

Roger on the above. I'm open minded enough to understand that each situation may be different. Thanks for the replies and sorry for hijacking the original post.

I cant agree with the "top antenna has the most noise". I have multiple,as in many DB-224's top mounted on 400 +foot towers and and able to add preamps to the receivers and still not problematic noise.
Got to be something else.
Same here but all the sites I’ve used reserve the top rung for receive only antennas. I’ve always had better receive from a top of tower receive only antenna feeding a good preselector then preamp to multiple receivers. Never had any noise problems. I’ve also not heard of a problem like this except for a few specific systems that had something wrong like passive IMD from tower/antenna mount corrosion or something similar.

I've had a microwave link generate RF smog at a 10uV level from a 400MHz antenna 2 meter behind its dish. Moving my antenna 10 meter in front of the dish got rid of all the smog. It had to come from the electronics and not the microwave RF signal.

Some rotating top lights can be a nuisance, especially if they are the LED ones and its sliding contacts can behave differently depending of the weather.
