ModuleFrn

[dh9yap]

Hello ... it's about the ModuleFrn. Would be glad if the voice from the Svxlink (internet) is also transmitted to Freeradio Network Radio. At the moment, only the voice is transmitted from the gateway (local) to the freeradio network. I would be glad about an implementation. 73 Jürgen DH9YAP

@sh123?

Halllloooo

[sh123]

@dh9yap, can you explain your use case in details, do you want cross link SVXLINK and FRN, so audio streams will flow between them?

[dh9yap]

@sh123 Hello ... Yes we want to connect Frn and svxlink. We use svxlink on Freenet PMR and CB radio ... not in amateur radio .... the audio from Frn is transferred with your ModuleFrn into the svxlink network ... but what from the Svxlink network comes is not heard in FRN ... it would be a very nice option for us ... 73 Jürgen

here our project http://funknetz.nrw.europa-welle.de

[sh123]

@dh9yap, QsoFrn implements Async::AudioSink and Async::AudioSource, which are part of svxlink Async framework, module does have control over audio sink and source, these are provided and configured by root svxlink.conf. If you think that problem comes form Frn module, please, share more details, like, your stream setup, deployment setup and svxlink.conf / frn config file.

[dh9yap]

@ sh123 Hi :-) Here are our settings. From other gateways, from the Svlink network, the audio is not transmitted to the Freeradionetwork. From the freeradion network to the SVxlink gateway, audio is being transmitted. I drew that on paper. https://drive.google.com/file/d/1zmHLtzQwCBrXvWuzECW-nuGTSjjZGvZ0/view?usp=sharing

@dh9yap, current logic looks like this

1. incoming: rig -> alsa:plughw:0 -> [Rx1] -> [FreenetLogic + ReflectorLogic1]
2. outgoing: [ReflectorLogic1 + FreenetLogic] -> [Tx1] -> alsa:AMP1 -> rig

(1), should work, because Rx1 is the AudioSource for the FRN module, it reads audio from this source and streams it into its network (2) is not going to work to send audio from ReflectorLogic to FreenetLogic, because Tx1 is the AudioSink, this is where FRN is sending audio coming form its network, it does not read from it, it is not bidirectional

To make it work audio from the ReflectorLogic needs to be routed into RX of the FreenetLogic, so it should be something like RX=NetLink1

[ReflectorLogic1] -> [NetLink] -> [FreenetLogic]

but in this case audio from rig won't be routed into FRN.

Maybe you can run separate svxlink instance on the same hardware (which will behave as a Reflector<->FRN gateway) just to route audio between ReflectorLogic and FreenetLogic without using rig/alsa?

[dh9yap]

@sh123 maybe dl1 HRC can help us I have already contacted him via e-mail. He looks after the project here in DL

[dl1hrc]

I have no experiences with Frn, just to be sure what you want to realize:

• a local simplex-link on CB or PMR (via Rf)
• a connection to a special CB/PMR-Network via a ReflectorLogic
• connect all of them together Is this right?

The first thing what strikes me is that ReflectorLogic is not active: [GLOBAL] ... LOGICS=FreenetLogic ... should be

LOGICS=FreenetLogic,ReflectorLogic

But there should be an error message in the svxlink log, isn't it? Please could you give me a short feedback.

[dl1hrc]

The other thing is the alsa definition in your [Tx1] section, it is different from the [Rx1] section and defines a special alsa functionality. What is the reason for this? Did you define an alsa device with name AMP1 in the asound.conf? I recommend to use a "normal" alsa:plughw device first as already used in the [Rx1] section. Before using special alsa extensions the audio stream should flow without any sorcery ;)

[dh9yap]

@dl1hrc Hello Adi Hi Adi To the point: Yes you understood me what I intend to do. If I did not have a network, everything would be fine. The Reflectorverbund gets the audio from Freeradionetwork but they can not answer because the audio is not transported to Freeradionetwork.

73

Sorry had modified the svxlink.conf for Github. I forgot to add Reflectorlogic. Have changed that. AMP1 is the compressor ... I have disabled now and everything works with standard. ssh123 and I suspect that the passage of the audio stream from the Reflector_Netz to the Freeradionetwork is not directly on the module.

How does the Echolink module work? Is the audio from a Reflectorverbund also not transferred to Echolink?

73 Jürgen

[dl1hrc]

Is the audio from a Reflectorverbund also not transferred to Echolink?

No, connections between EchoLink and ReflectorLogic and SimplexLogic are working all the way without any problems. Has it (Frn configured together with a SimplexLogic and ReflectorLogic) ever worked in the past or is it the first try to realize this setup?

[dh9yap]

@dl1hrc @sh123 It does not work with the Reflector! With the SVXlinkserver and a Netlogic it worked only with a trick, described this in a previous text here. In the old days, it only worked with a little trick. We had the module integrated in the NetLogic ... But since we switched to Reflector this does not work.

if you compare Echolink and the ModuleFrn you could then see what it is.

[dl1hrc]

ok, I think we should try to solve the problem via eMail for now. If the problem is solved we will report it here.

[dh9yap]

Hello to all readers ... Adi is in the process of solving the problem. It will take some time. At the end of June he wanted to look at the code ... 73

[sm0svx]

@dl1hrc, do you know what the problem is? Have you reproduced it locally? SvxLink core or in the module?

[dl1hrc]

is not really clear at the moment, will see what I can do next days

[dl1hrc]

yes, it's a bug. The audio stream isn't send over the FRN-connection if received from a connected reflector. Local audio stream from Simplex/Repeater-Logic will send to FRN als well as the audio is streamed into the reflector network received from FRN.

[dl1hrc]

The problem is the State-enum in QsoFrm class or more clear the assigned state depending from the type of audio stream. The local handled audio stream (Simplex/Repeater-Logic) has the state STATE_TX_AUDIO while the audio stream from reflector network gets the state STATE_IDLE, so the writeSamples method ignores the samples received from the reflector network.

[dl1hrc]

ok, the real problem was to use the local squelch as the only criteria to send the audio stream into the FRN network. If you are using a radio+squelch (vox, ctcss,...) everything works fine, but the audio stream received over the reflector network does not have a squelch criteria, so we have to detect an incoming audio stream independently if it is received local or over the network. In both cases we have to request the permission to send (RQ_TX0) and set the state to STATE_TX_AUDIO_WAITING. The diff is quite easy:

@sm0svx Hello Tobias 😊 When can we expect the new trunk? 73 Jürgen dh9yap Very Good Job !!!

[sm0svx]

Since @sh123 is the maintainer of the Frn module I'm awaiting a thumbs up on the suggested fix. Thanks for your work Adi!

[dh9yap]

@sh123 Please respond once to the request of Tobias so that the topic can be closed and the change can be incorporated into the trunk. Its Frn module is much appreciated by many ... it works very well after the cleanup of Adi.

73 dh9yap or 13dkdo03

[sh123]

yes, do it

[sm0svx]

Thanks for confirming. Done.
