• 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 Old Big Stick. The bottom 239 connector was removed and I connected a new one. It seems to receive OK but has a super high SWR, all the way up on the scale. I changed the top whip and tested again but still NG. What is in the bottom section that I can't see that can cause the problem. All I see in the bottom section is the coax wire coming out. Anyway to do some testing on this. Its now turned into a quest. I have a second one but it works fine. Ron

Sounds like the SO-239 was salvaged and the rest sold or thrown away. Considering how they were put together, save your new connector and the top portion and throw the thing away.

Do ypurself a BIG favor, never mind this old, used, broken crap you keep playing around with. Antennas in time degrade,break, and are unsalvageable.. Go out, SPEND the money and get a new antenna it will last you many years and will be cheaper in the long run.

Sounds more like a quest than really wanting to replace the antenna. Since anything can be used as a RX antenna, even a coat hanger, I wouldn't put much faith in that it is receiving OK. It's possible that the coax has corroded internally, since water likes to wick up coax braid, or the top connection is corroded. I don't know how far you want to take it apart, but I would look in those directions. Use an OHM meter to check for continuity, as any high resistance is going to give you a high SWR.
