• 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.

Messenger M4V Help

I got an old M4V that needs some help... It powers on, but all lights come on and it won't actually do anything... I thought the keying Transistor fried and replaced it but no luck... Nothing appears burnt, and no smoke came out of it... Any ideas??? Or names of shops that still work on them??? I'd hate to give up on this one, it's a really good amp!!!

its funny how everyone turns into a lawyer on here when someone asks about more power...
I think you'll find, other than a select few serial cranky types, the vast majority of us don't really care. What I find interesting is individuals that will dig up ancient threads to restart the argument.

Where you'll usually hear comments is those pointing out the obvious, focusing on RF power output as the only measure of a good radio system is ignoring reality.
