• 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 just found out how to disable the noise blanker "extender" feature in my low-band Maxtrac...hold the MON button down until it beeps a few times and checks off the middle left cross-hatch on the display.

So, I am reading this is meant to attenuate the receiver in short pulses to reduce ignition noise. This radio is installed in a Prius, wired to the trunk battery, and the car electrical system is very isolated from the engine, so ignition or alternator noise is not an issue. Would I be correct in assuming I can just disable this and the RX performance will improve? I am not sure if it does anything else that would improve performance. I have always had relatively poor/weird RX issues with this receiver, such as what seems like squelch clipping, puttering noises etc.
