2025年1月24日 · New to radio and am trying to understand what my setup is actually doing. I have an RTL-SDR and have some success decoding P25 with SDRTrunk and Boatbod OP25. If my understanding is correct, SDRTrunk can monitor the entire available bandwidth around some frequency of the SDR dongle and if...

2015年9月24日 · The field of SDR as well as the general concept in the radio monitoring community has really exploded in the past 3-4 years for a variety of reasons: the cost of such hardware has been steadily dropping because it's easier to develop nowadays, people are more talented with the code needed to control such hardware, and other reasons.

2023年5月26日 · Hey everyone! So I recently got back into my SDR and radio hobby and was looking for a good way to scan my local PD/Fire without the need for a dedicated scanner. I had my old RTL-SDR lying around and started researching for ways to scan P25 conventional and NFM using the same software. Some of...

2022年11月26日 · Is there any software out there that can turn an SDR, or a couple of them into a "scanner", I know about SDR trunk, but I am talking about software where you can put in a list of frequencies that are not trunked, and have it scan threw …

2023年7月29日 · So the plugin I use on sdr# 1742 is called frequency manager. Pretty basic. Lets you create groups and populate with freqs of choice. I also use another called frequency scanner that lets you define scan ranges. Not sure what version of sdr# your running. Plugin compatibility has changed over the years. This is what the freq manger I use looks ...

2023年10月5日 · For full trunking, you will need to edit the networks, sites, site loader, frequencies, and groups files. There are examples within each file. To start, you will need to run 1R and FMPx, x= fmp24 for RTL SDR dongles or similar devices, FMPA for Airspy devices, and FMPP for SDR Play devices.

2020年9月16日 · I too am looking to use SDRTrunk to monitor my local FDs TGs on our county's 850 MHz P25PII system (my project for Thanksgiving week, though I've had the RTL-SDR dongles since last August). Question: will SDRTrunk monitor the system with one dongle (3.9375 MHz between lowest and highest frequencies)?

2024年10月25日 · My only real trouble is that I'm largely just noodling around with the thing, because I'm still figuring out this whole SDR bit. I was away from radio for a while (financial concerns,) and now that I'm getting back in, I'm seeing one important thing - technology has left me in the dust! So, I'm playing a lot of catch-up here.
