Good Question!I noticed in the "innards" of an SD card there is the ESN for the scanner.
Does this mean the SD card for scanner A can't be popped out and placed in scanner B and successfully used?
I say it wont work because the checksum will fail.The ESN wont match the other radio and it will tank.Hey ya never know though.Good Question!
I have only one HP-1E and 436HP so I cannot give it a try, but I do keep my SD cards for these two scanners in separate containers and clearly labeled since I am almost positive they cannot be substituted for each other.
As a WILD guess I would say that unless the ESN is checked for they should work as long as it is a 436 vs 436 and a 536 SD card and another 536 SD card.
If someone will try it, we will soon know.
I agree, if the ESN is being checked in say a paid upgrade. I think it would prevent people from upgrading more than one radio with the same payment.I say it wont work because the checksum will fail.The ESN wont match the other radio and it will tank.Hey ya never know though.
AFAIK no paid upgrades have been announced but why a Firmware update would query your ESN unless the ID of the radio (436 or 536) is contained in it since the firmware update is not tied to the individual radio but to the kind of radio you have. However, the radio ID may very well be in the ESN in which case it will be needed.I'm kinda lost on the "paid upgrade". . . I'm unaware of any type of paid upgrade for 536 scanners.
Just a guess but probably the ESN on the SD card identifies what scanner it is for the sentinal software to differentiate multiple scanners for firmware updates etc So if you put the sd card in another scanner the ESN. Probably gets over wrote so shouldnt heart any thing
