APX “Legacy software system key” flash

[Ant9270]

Do you need Legacy System Software Key enabled in your flashcode to alter settings or import a key to edit a Smartzone system? I’m having a moment. I’m looking at a radio with “smartzone system operations” enabled, but it does NOT have legacy software key.

A trunking capable APX is going to have either QA01648 ASK Enable or QA01749 Legacy SW System Key Enable in the FLASHcode. If the radio has neither option, then it's pretty likely someone was screwing around with software they shouldn't have been.

If the radio has SW Key enabled, you can use either a software key or an ASK. If the radio has ASK enabled, you can only change some system parameters with an ASK, the software key will not work.

I figured. Very odd flashcode on this particular radio I’m looking at. Looks like someone played with a certain tool indeed.

Without QA01749 Legacy SW System Key Enable in the flash, you won't be able to make changes to any of the critical trunked system parameters.

So to say, having QA01749 Legacy SW System Key Enable is the more flexible option out of the two?

Correct.

 

[navymrh90]

Correct.

Thanks! On an APX8000, does the option QA01749 Legacy SW System Key Enable need to be added as an option to the flash-code or is it already included by default? Trying to make sure that flash-code is valid with Motorola.

The flashcode includes the option "QA00579 Enable Dual Band Operation", which would indicate an APX7000 or 7000XE, the only two platforms that particular option is valid for. When APX radios first started shipping, there was no discrete soft or hard key options, they all required hard keys, period.

This is indicative of an early-manufacture APX7000, not a whoreflash.
