TMD700 power up Reply

I'll ask here as I suspect the TMD700 is a lot more commonly used by those interested in APRS.

I use a TMD700E mobile.

I bought this rig on eBay and initially it used to power itself up when it got voltage on the power cable. I reversed a broadband receive mod which seemed to be stopping more useful features like auto repeater shift. Doing this causes a master reset back to defaults. After it I found I always needed to power up the rig manually. There isn't any menu option that I can see so I just accepted that's how it works - maybe the broadband receive mod altered that too.

I use a boom mic with a PTT switch mounted on the seat as it won't fit on the gearshift. I occasionally catch this when getting out but have always noticed in the past. The other day I didn't and the rig was powered up with PTT on. I noticed the switch position when I got home. The rig was not in transmit and sfaik never was. Since then the rig once again powers itself up whenever voltage is applied.

Has anybody else seen this behaviour? Is it documented somewhere and I've missed it?

I've used mine mobile for several years and never seen, nor heard of this. AFAIK, it's not normal for the 700.

I've owned at least four D700's and none of them have ever exhibited this behavior. The first two were purchased a couple years after the D700 was originaly intoduced while the second pair (which I still own) are both at least three years old. All were/are the "A" version.

I've never heard of any D700, A or E version, doing this. I do own a Kenwood TK-981 commercial 900 MHz mobile that does this but I understand it's supposed to do that. No so on the D700 though . . .
