• 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.

XG-100M won't keyload

I have a XG-100M/CH721 that refuses to keyload. KFD Shield has no problem loading the 100P with the same keys. I have a OEM 14002-0143-10 REV2249 cable that was modified from the MX connector to Hirose. I go to Keyload - KVL and hit menu, the radio just sits "Idle". I can't read or load any key information. Below is the firmware versions read out just now.

Obviously, the firmware update on the mobile is a bit different than the portable, so I didn't go monkeying around there, afraid to brick it.
I have firmwares: 100M XLP R06T02, CH271 Main R07G17, DES-CFB R04B03 & HALM R04A01

I'm not even sure if firmware reflashes would do anything. Any help will be great. I do have 35, 37 & 45 in the feature set, so I "should" be good to go.

I've never been able to keyload a 100M except with Harris KeyAdmin and a DB9 programming cable.

That's discouraging. Even with the OEM cable and a real KVL?

After spending too much time reading this morning, I'll dig into the mission plan and make sure there isn't something stupid turned off.
