• 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.

Hello everyone

I just became a member after being a forum reader for the past several months.

Needless to sat that This is my 1st post.

Anyway... I bought a brand new 29LX about a few months ago. This weekend I decided to add variable power to it. I had civil said you did too at this mod to the radio.

1st I went ahead and grabbed a scrap piece of PCB board and mounted t and there is only 4 wires going into the radio and soldering inside. So I soldered 4 wires inside and took it for a test drive. This thing worked ridiculously well. I was very happy with the performance. Then it was time to go ahead and make a perminant pcb and box for it. So I did, however by mistake I took the wire that is supposed to go to the front hole of the cut jumper and hooked it up to the inductor/coil/ choke side and vise versa. The new pot started to smoke right away and I could not get any of the beep sound that you hear when you press buttons on the CB radio. So I quickly disconnected everything figured out what my mistake was, and corrected it. Now when I press the PTT button, my SWR / power meter does not move at all whatsoever, however another CB radio that is about 1 foot away will pick up only white noise when I key the mike and not any sound (or my voice from the microphone).

I check to see if the microphone was gone but it is not. So I am guessing either the audio amplifier, or the synthesizer, or something else has been damaged.

Would anyone here have an idea of what part(s) and/or components I may have caused damage to inside the radii? and how I would go about testing it?
