• 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.

Problem programming Kenwood TK-3301

I received this TK-3301 ProTalk with some other stuff and only some channels worked which may have been standard, I don't know.
I downloaded the KPG-121D V1.01 software and have the engineers serial number (posted in another old thread) and programmed in the 446 MHz channels that I wanted. I have the correct programming lead.
Now it won't transmit, just the LED flashing Red but it will receive on all the channels and when a signal is being received the LED flashes Green then Amber and alternates and when the signal has gone it goes back to flashing Red. The same happens if I load the standard channels that the software comes with.

Now the strange bit.... in the software when in Test mode and using the software button to transmit, it does, solid Red TX LED and received signal on another radio. No flashing Red LED on standby and a solid Green LED or receiving a signal. Come out of Test mode and it goes back to the above posted issue.

Any ideas what the issue could be as I am stumped at this point?
