900mhz

I checked around but I can't seem to find if the XPR5580e can be unlocked to transmit 902-928mhz. I believe Motorola skips these frequencies but I understand that some radios can be hex edited to work outside of Motorola specifications anyways. Just curious if anybody had any more information or...

Has anyone been able to hack the PD-782 U5 to allow for the 33cm ham band? I recently purchased a used (new in open box) PD-782, and am trying to get to setup for a 900mhz DMR repeater I’m trying to build. I have a couple XPR-6580s now, but would like to add a Hytera to my existing PD-982 and...

I need some assistance in figuring out how difficult it is in my CPS to hex edit either an XTS1500 or an XTS2500 to operate on the 900MHz spectrum, primarily the 33cm band of 902-928MHz. Can either radio be modified to do the 33cm band? If so, which? I’m trying to get into P25 900MHz via a...

Hi. This is my first time to create a forum and in need of help. Basically I have an SDR type Cellular base station with two separate radio channels with 3Watts each. I have two options a) use panel antenna for each or b) use an omni antenna but will naturally need a combiner. My concern...

Hi, I have been researching on medical device frequencies and I was wondering if anyone know if there are any interference issue in the 900MHz range in hospital environment. If 900MHz is an issue, what frequency range would be appropriate for medical devices? Thanks, chu
