• 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.

And why would you need to be transmitting on frequencies assigned to UHF TV channels? 🤔

This frequently band is used for wireless microphones, but likely with no common modulation bandwidth you would find in a two way radio,
I believe the Quansheng UV-K5 series transmits and receives up to about 600MHz. But its not legal to use anything but FCC type accepted equipment there and it will be very low power like wireless mics.

I think it just receives up there, but I could be mistaken.

I have one and it transmits there but not at rated power. I'll measure it and report back.
Mine does a little over 3 watts at 550, nothing there though. Yea, it would be illegal in the US.

Since people are mad at me for asking I will clarify, we use this frequency at my work for microphones and our PA system, and we needed a radio to test the system because our mics are getting repaired after someone decided to drop them all out of their truck bed

just pick up a used mic transmitter...you will always have a spare. and depending on the brand of wireless mic, the modulation is very possibly not compatible with a 2 way radio!
there''s piles of orphaned (without receiver) transmitters on the various auction sites!

A 2 way is probably going to have very low audio since it's only 2.5 kHz deviation. The bandwidth of wireless mics runs from about 50 to 200 kHz from what I'm seeing, the mic receiver might not even open squelch for a narrow signal.

And this is assuming its an analog mic. Most likely its a digital with a propreitary waveform.
