We’re having problems with simulcast distortion on the Whistler 1040 and 1065 that we used to run Broadcastify and Zello for Portland and South Portland fire department.
apparently these models of scanner although they support basic P 25 phase 1 they lack proper demodulators for use on simulcast systems such as Portland’s.
I’m planning to invest in a box of SDR dongle‘s and I want to make sure that I’m going to be able to decode everything reliably.
So I was looking at the database information for the Portland PD 25 system and I found what looks to be some conflicting information regarding demodulation.
See attached screenshots for the main page and the page that I get when I click simulcast link.
One page says Phase 1 the other Phase 2? This might just be a database discrepancy.
is the demodulator correct?
I was checking out a tutorial for SDRtrunk software and it only showed C4FM and Simulcast LSM support in it’s P25 decoder. I’ll probably have most of my discussion in the SDR forum but I wanted to check in here to make sure I’m going to be able to find a compatible decoder.
Thanks for any feedback
