I have this hardware and I want to build a RX only iGate for my pi3B which I can leave on always.? Can you suggest a set of instructions or walkthrough? FYI I am in Alberta Canada.? Thank you.
- raspberry pi 3b
- nooelec rtl-sdr v5
- 144MHz antenna

I followed some older instructions and got things running but it never gets a packet
these are the instructions:

In the documentation directory,? , you should find a file called? Raspberry-Pi-SDR-IGate.pdf.

If you run into issues, let us know exactly how far you got.

Hello runcer,

Looking at that original article you posted, that's dated from 2017 running Direwolf 1.4 which are both very old.? I would recommend that you start with a newer OS such as Bookworm (newest) or Bullseye and build up from there.?
To get a RX-iGate working, there are a lot of guides out there but it's not clear how much instruction you need.? I would recommend to start with this doc:

??

Let us know if you're looking to follow a document step by step to build things yourself (best way to learn) or maybe you want to download a pre-created Raspberry Pi image. Once you tell us your desired approach, we can recommend some URLs to check out.

i wasn't getting any packets so I added the gain =g 21.0 is it necessary to that?? I know that the iGATE is talking to the server because my icon shows up on but never any packets come through, I have changed the freq to 144.39.

rtl_fm -f 144.39M ?-g 21.0 - | direwolf -c /home/pi/sdr.conf -r 24000 -D 1 -

Just out of curiosity, are there any packets to be heard in your neighborhood? You said you were in Alberta; that's a pretty big province. Where in Alberta are you? A big city like Calgary?

You might want to tune in a regular 2-meter radio and listen for the characteristic squawks of live packets. Otherwise, you may be on the start of building an entire APRS infrastructure from scratch.

Andrew, excellent and fair point, I am in a pretty rural location, I have been able to decode packets in the past using my Openwebrx setup but lately not at all, the previous decode was using a long wire in the trees.
openwebrx can see the packets but not decode them because they are so weak, this may be the whole issue.? I did an apt-get update and upgrade and lots of things upgraded, so I booted and now it will just run and I will see what happens.

many thanks for the help.? Joe
