• 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.

Hi,

This is my first Kenwood, so please bare with me. I stated programming it up today. And after I programmed a few channels. I have a few questions.

1. Is fleetsync a software or hardware option? I could not find any place to disable it in software. I assume I have to go find the chip and remove it?
2. Is there a power setting? Or is it always on high power?
3. Is there any sort of emergency mode? Every 10 or so key-ups the mic stays open, and you have to key again to stop transmitting. I'm not sure if that's a feature, or me buying a third party mic which is stuck open.

Thanks

Matt

Answers to your questions (to the best of my knowledge):

1. The TK-840 didn't offer Fleetsync as an option. If your TK840 has Fleetsync, it is an add on (a board plugged into the main board from Midians, for example), so it would be a hardware option at this point.

2. Power setting is done in Test Mode within the software or front panel tuning. It is adjustable, not sure to how low though, never tried it. The rated transmit power is 25 Watts with a duty cycle of 20%.

3. You have something going on somewhere, maybe a flaky microphone. Do you have access to another microphone? I would try a different microphone before anything else. It might be tied in with your first question about the Fleetsync; the board may be malfunctioning, if installed.

Best thing I could recommend, if you are careful, is to remove the two screws and see what is under the cover. The KDD-4, if mounted properly, should be mounted behind the faceplate (according to my service manual). The Fleetsync board may be mounted here as well. You need to remove the control panel to see if the KDD-4 or if anything else is installed behind it.

Once set up, the TK-840's are a great radio for Ham and GMRS use. I have a couple among my hoard of radios here.

Ok. I finally had a chance to open the radio. Is this an external fleetsync board? A search for the esn came up with nothing. It is in the main unit, not the head.

Thanks

Matt

Any markings on the bottom of the board?

Could very well be an ani board.
