pm400
i have a lot of pm400 radios 465 to 470Mhz i need to program them into 461.000 i am sure i could check some hex code and do this but i need help, i have a read from a pm400 that is in the right range can i change something in the hex code so i can use this code plug. thank you John C.
Re: pm400
Im a bit confused. the range should be much wider than 465-470. I have a PM400 with channels from 451 - 468 mhz. What does the bandsplit show when you read the radio ?

The UHF PM400 is available in two splits: 438-470 and 465-495.
Re: pm400
The Model no. is AAM50SPF9AA3AN THE LOWEST FREQUENCY IS 465.00 TOP WILL GO AS HIGH AS 512 THE ONLY THING I SEE THAT IS ODD IS THE SPF I THINK THE RADIOS WERE A SP MODEL FOR THIS RANGE.

Re: pm400
SPF is correct and normal. Right from the Motorola manual:ashtin wrote:The Model no. is AAM50SPF9AA3AN THE LOWEST FREQUENCY IS 465.00 TOP WILL GO AS HIGH AS 512 THE ONLY THING I SEE THAT IS ODD IS THE SPF I THINK THE RADIOS WERE A SP MODEL FOR THIS RANGE.
S = 465-495 MHz
P = 25-40W
F = PM400
9 = Programmable
AA = Conventional MDC
3 = 64 mini-U (64 Channels, mini UHF antenna connector)
Re: pm400
Not special production. Those are "S" split radios. Info on how to take those radios out of band has been posted here numerous times.

Re: pm400
You do it by typing PM400 band hack into the search box, there you'll find a discussion on region hacking, scroll down to the post by toshi x and you'll find a post on changing the frequency limits. Be aware that doing this means that the radio is no longer FCC approved.
