I'm pretty sure that by "SWL" they mean unlicensed/public access, but I'm not entirely sure, as I've read in several forum threads that it isn't appreciated when you connect to an repeater/node and don't identify or say something. I suppose this is because the EchoLink system announces when a remote user connects through the system, but doesn't necessarily announce the call of the connected station.
The last part is key. You can't use the echo link system without being a validated licensed amateur. You logistically can not listen to this system without also being allowed to talk on it. Contrast that with "traditional" short wave listeners. Anyone can buy a radio and listen without being licensed to talk on it and there is no way technologically that you can prevent them from listening.
Wow, in response to the comment above, when has listening ever been considered rude? Most consider it a critical skill to use in ham radio. With so many repeater groups jumping down people's throat for transmitting on their repeaters, is it no wonder that many choose to listen for extended times before jumping in to initiate a contact on their own? So many grumpy people so fast to say what's rude. I thought ham radio was about learning. One of the ways people learn in this hobby is by listening. Why in the world would that ever be considered rude? Each repeater and group can have its own culture, so to speak. That can take more than 'a minute or two' to get a sense of. Here's a case of one person trying to be polite and another getting all judgy with the response. Blacklisting? For someone LISTENING? Wow. Ooohh, feel the power. No wonder people are hesitatant to broadcast; sadly, we see similar responses on the air all the time. Less judgment, more patience and mentoring please.
When you connect, you are announced. Now you won't talk to us? Why did you bother connecting. And now you're going to drop the connection without saying anything? That also is announced. So all these "listen only" users are constantly connecting and disconnecting, getting announced each time, and not saying a word.
Additionally, many repeaters have a limited number (sometimes only one) of available connection slots. So you are going to now sit there and just listen, taking up a slot that a real live person could have used. And I can't call out while you are connected either, even if there are multiple slots.
Yes, connecting without saying anything is rude. If you are not going to talk on this two way medium, why are you bothering to participate at all? To say the least, if I see you connecting to my repeater and disconnecting and not saying anything when directly spoken to, you're going to end up on my blacklist and not allowed to connect at all. You wouldn't walk into a restaurant, stand in the middle of the dining room, and stare at people, and then refuse to sit at a table. You shouldn't expect to connect to a repeater via echolink and refuse to talk either.
Similarly, why would you connect and then immediately disconnect? If you're having technical difficulties with your audio, use the echolink test server until you have it fixed. If you're disconnecting because you connected and didn't immediately hear any activity, you're doing it wrong. If you want activity, put out a call. Maybe conversation just paused when your connection was announced. If you immediately disconnect without talking first, you'll never know if people were talking before you connected or if people are there but listening.
As an alternative to connecting to repeaters and listening, find a conference server instead. Conference servers have a very high number of slots, and I think they don't announce when you connect and disconnect, and won't prevent anyone from dialing out. Also, if you want to exercise your language, I can understand not wanting to initiate a conversation, but at least try to respond if someone talks to you. Amateur radio is all about communication, and I'm sure if you try you can find someone who is willing to help you stumble through and improve. Mentoring is a big part of amateur radio, but if you refuse to talk, we can't mentor you.
It is good amateur radio practice to listen before speaking. So if you connect, wait a minute or so, and then say something, that's perfect. Just don't sit there for hours, or connect and then disconnect right away, especially if someone tries to talk to you.
I do not consider it rude if I listen to see if anyone is online. I do the same with my 2 meter. It is called "common courtesy". If there is someone online, and talking about something that is of interest, I will join in if possible...otherwise I will listen to see if I have anything to add to the conversation. Again..."common courtesy". In fact, there was a "node" in Alaska that said LISTEN before first transmission to make sure the frequency is clear.
I am bench testing a new repeater system with a Yaesu DR-2X, ARCOM RC210, and the RIM_RC210. The AllStar Node is working great, but there is a problem with EchoLink users connecting inbound. If I connect to the user first and then disconnect, they can then connect. I have the Port Forwarding set up correctly. We had EL previously using a ULI and had no problems. I checked and rechecked the rpt.conf and echolink.conf and can find nothing apparently wrong there. Another problem is when I connect to the EchoLink Test Server, the return audio is awful and echoes, not a pun intended.
Patrick,
I suspect what you are seeing a a hacker in your system
He does not know this is a radio system and is probing. Likely does not understand if he is even looking and not just running a script.
Now, when I mentioned the hack, as I have witnessed, they have come though the firewall in a allowed exception on the port. Our security for the software port has to be sealed up. They are looking for asterisk boxes. They try all extensions and normally do not find much as they are looking for open/unsecured extensions and most of us do not have 3 digit extensions/nodes as they likely then try 4 digits and then 5. The area they are most likely to pop up is echolink from a improperly guarded iax or sip extension in the conf.
But if you watch asterisk in the foreground, you can quickly determine what it is. Since the hack scripts issue a lot of extensions very quickly. And you would likely see them in the verbose output. And they are relentless. They do not sit there manually, but work from automated scripts.
echolink security is kinda like our own, But if the injection point is our system, our software sees it as a valid echolink connection, even though it is not. It is the caller id of the hack starting with exten 3x(x).
Think of it as a spoofed CID.
When they run though the scripts and find nothing of interest to work from, they often just give up. But there will be others down the line. You can capture their IP and just block them in the firewall.
If you later determine it is a hack, contact me off-list. I can help.
If you can determine it is the relay or proxy, try to ID it so they can be informed.
But do not change your config much until you know what it is.
Here is an old dialplan app I built some years ago to do db lookup for elink,
however, without a dialing context example, probably worthless to you unless you build your own.
Mine is a bit complex to just paste here.
But you could provide a extension number and call it from the dialplan using the phone patch or using the context [echo_lookup] .
But I will highlight the asterisk command to do this from the command line.
I always use proxy servers where a direct connection is not possible. The callsign should be the users that way. But the folks that run the relays always seem to have issues with whose ID is forwarded.
I'm an absolute newbie to GMRS. Just got my license last Thursday (04/21/22). I've been a Ham for 17 years and run an EchoLink node from my home for a local repeater, and was wondering if there was an EchoLink-like service for GMRS? Any and all help is greatly appreciated.
Probably the closest thing used as such is Zello, which unlike echolink, doesn't require a ham license. I'm not up on all the hardware bits involved, but they'll usually have a channel set up tied to a node or repeater, with admin permission required to transmit into the channel.
On a side note, I've been pondering doing something similar to your setup with Echolink, so i can access a local repeater remotely, just haven't dug into if I can make it work with what I have or need another radio (oh darn!).
I have a repeater on Zello and it's a kludge to get setup and working.. But once you get through all that, it works fairly well. Also, FYI, although you dont need GMRS license to use Zello, you DO need a GMRS license to transmit on a repeater connected to Zello.
Thanks for the responses. What I'm trying to determine and accomplish is this: To determine if there is software like EchoLink that I can install on my computer that will allow me to link to a GMRS repeater and get on one of the regional or National nets. None of the GMRS repeaters in my area that are also in the GMRS Network are close enough for me to get to over the air. If that possibility doesn't exist, can I go to the GMRS Network map and link into one of the repeaters shown there and get on one of the nets.
It takes searching out the channel associated with the repeater, and then being granted transmit access in the channel by the admins (usually they like to see your call sign in your username/profile in hello to verify).
Many thanks for that info. One last wrinkle; I run Linux on the main computer, although I have another laptop with Windows. Is there a version of Zello for Linux, or must I use Windows. I don't want to run Wine.
