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...

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.

2024年12月23日 · I am a beginner trying to experiment with listening to the things I can figure out with my new RTL-SDR v3 dongle. So far, I am able to listen to unencrypted local public safety (with SDRTrunk) and FM broadcast radio (with SDRSharp). I am using the dipole antenna that came with the bundle for these 2 successes.

2022年12月17日 · Actually, since the early 2010s increasing numbers of 'traditional' SW radios are actually DSP, which is an SDR in a chip, configured to work in a "radio" with buttons, knobs etc. The internal circuitry is analog - digital - analog, all done on the DSP chip. The main difference you get with an SDR is the computer interface and a lot more ...

2024年11月12日 · In my testing of various software and hardware, the SDRPlay RSP1B with SDR-Trunk (nightly build) along with the comet miracle baby completely eliminates simulcast distortion. It outperforms even my SDS100.

2020年2月20日 · The audio mute is independent of the SDR# squelch but in the end does the same thing (maybe better). You may get better results using this with scanner plug-in than using the SDR# squelch with scanner plug-in. 'Noise protection delay' This helps eliminate the crash at end of transmission. Don't use it if also decoding digital signals as well.

2024年10月22日 · SDR# volume, in v1920 setting it to 0dB should be a good starting point. The decoded audio volume (in the plug-in panel), setting it from middle to MAX should get it at a 'normal'* level. * There is no audio AGC to the decoded audio so different levels may be heard and would depend on the radios alignment of its voice audio level or if someone ...

2024年11月16日 · Hello, I've got an RTL-SDR and I have it working on Window8, Win10, and Ubuntu. On the Win8.1 machine, I can listen to it with HDSDR, SDRConsole, CubicSDR and SDRSharp. However, SDR# cannot output to my "default" audio device (Dell USB Audio); It only plays through the tiny laptop speaker...

2025年3月23日 · I have been running SDR Trunk for several systems for a few years now (plus some NBFM freqs), with excellent coverage and audio. I recently upgraded my antenna to enhance coverage, but it feels like I made things worse for one of my systems. Some of the traffic channels seem 100% with clear...
