SDRTrunk Raspberry Pi with SDRtrunk

[AngWay]

Just wanted to show everyone my setup i'm using a pi 4 with two dongles and a LNA going out to a J Pole on top of my house i'm running SDRTrunk i'm also testing out OP25. i'll attach pictures. Thanks to everyone on this forum that has helped me so much, it's really meant more than you know and especially a thank you to @dave3825 for your patience

Hard to tell but are you only using the screen on the pi? I have teamviewer and vnc viewer and I remote into my pi. Much easier on the eyes.

i use the screen on the pi when i'm just needing to see the traffic going by but if i need to edit anything or whatnot i use vnc.

I have the 3b+ and never had a screen. There are some nice large screens that the pi mounts to the back of but my intention was for headless use in my truck which works good.

yea i had that thought to of putting one in my vehicle i bought a power inverter for that . i went with the 4inch lcd touch screen which is perfect u can operate it by touch and onscreen keyboard i can operate it and run anything just from the 4 inch screen. i tried using a pi3 but it's really to slow but the pi 4 handles it great i leave it on 24/7 i also overclocked it just so i could get the most out of it.

I've been researching building a Pi, but I am also considering an inexpensive laptop which could run Windows or Linux distros. How did you decide to go with a Pi build over a small laptop?

Well mainly i used the pi because of the size but i also used a hp elitedesk mini pc which gave more power. i do believe tho if i had used a raspberry pi 5 instead of the 4 it would have ran perfect .

@AngWay Thanks! What are you using for a display? SDRTrunk is my primary interest right now and ability to boot fast should I hear sirens (if it is off). As a new HAM I expect my SDR needs to evolve, which is why I was considering a small SSD laptop which would have a display, keyboard, speakers and a battery, whereas with a Pi I would need to cobble all that together

For sdrtrunk that is running on a hp elitedesk 800 g3 mini i just use vnc viewer to remote into it and handle what i need to do . when i had it on my pi 4 i was using a little 3.5 inch display that u can buy for the pi's u can see it in the pictures i posted in the earlier comments.

Raspberry Pi is great for rtl_fm, rtl_tcp, or OP25 single talkgroup decode. But if you want SDRTrunk with multiple channels and real IQ bandwidth, go x86_64. The Pi just isn’t up to it.

I've been running sdrtrunk headless (or w/ vnc display for setup/changes) on a pi5+nvme base w/ 4 rtl-sdr dongles for > 1 year with great success.

Can someone please tell me the benefits of raspberry pi? what i've seen its $100 , but my windows 11 laptop is $200 so whats be diff????

I wonder the same thing. PI's around here start at 100 and go up (cdn). For the price I can get laptops that can do more. Duel boot and your all set...

It depends on what you want to do. Pis can be portable and offer a lot of niche use cases. The current Pi 5 is fairly fast for radio stuff, but x86 will blow a Pi away anytime...
