• 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 have recently purchased a Motorola Maxtrac UHF (449.0 - 470.0 MHz) radio that has already had the VCO and the RX coils tuned down to 440, I am using the Motorola RSS Version R07.02.00a and when I add a channel it defaults as 446.0 but I can not tune below the default 449.00 range. I even try the shift key method and it still says "This frequency is invalid" in the top right. do I have to do something in HEX editor or am I missing something in RSS? Any help would be nice

If you have the correct RSS, then the shift method should work.
Remember that you must SHIFT all the characters except the . (the period) then re-shift for all the following 0's (zeros)
So 442.55000 would be SHIFT $$@ then unshift for the period, then reshift for %%))) and it should work.
If you are using a LAB version then the shift method won't work.

Thanks for the help! I think I forgot to completely enter the zeros at the end of the frequency with the shift mod. I also changed the Maxtrac.MDF files's band limits.
