Champaign IL ham radio repeater stream

I recently got a wild hair to stream some ham radio audio. I’m already familiar with the streaming process as I stream the Champaign, Illinois NOAA weather radio on Wunderground. My plan was to run a stereo feed with the left channel going to one repeater and the right channel going to the other repeater.

I found a decent deal on some Bearcat BC350A’s on eBay, so I purchased 2 of them. I debated on adding a second sound card to the computer streaming the weather radio, but decided it’d be easier to just use a second computer. Luckily I had an old Dell Optiplex GX260 here that would be suitable for streaming. I have the scanners hooked up to my old Samlex 1223 power supply. I had mixed feelings if this would even work as it had some issues with the HF rig, but so far it’s been running great. The antenna setup is tricky since I am unable to put up anything outside.

The scanners came with a simple window mount antenna with suction cups, but the gear was too far from any windows. When I first tested the audio, the signals would fade in and out and they were picking up interference from surrounding electronics. I did some research on splitting antenna signals and decided to go the cheap route. I found some RG6 quad shielded coax and used that to stretch across the room to the window. I have that hooked up to a 4-way cable TV splitter. I have several adapters converting from F to BNC. Some folks say that will cause a lot of signal loss, but in my situation it shouldn’t matter too much. I live within a mile of the tower that the repeaters are located on, so the using suction cup antenna in the window should suffice.

I decided to use Radio Reference to stream my feed. They mainly focus on public safety feeds, but they also allow ham repeaters on their network. Basically I send my stream to their servers and they stream it to whoever wants it. They can support tons of traffic vs me trying to run the feed from my home DSL line. I was hoping to get my feed approved ASAP as we were expecting some severe weather during the week.

I was approved on May 23rd and went live in the morning on May 24th. On May 25th, we were expecting some nasty weather. One of the repeaters on my stream is the local ARES repeater which runs weather nets as needed. Sure enough, we were under a tornado watch and even had a tornado spotted outside of Champaign. I checked the stats afterwards and discovered I had 35 visitors during that time. That made me feel like my efforts to get the stream going were put to good use.

As mentioned earlier, the stream consists of 2 repeaters split across the left and right channels. That is, you’ll hear one repeater on the left speaker and the other on the right speaker. The repeater on the left is the K9CU repeater on 146.760 Mhz. This repeater is connected to Echolink and is a general purpose repeater. It has a weekly Thursday night net open to all ham operators. (9pm local time) The repeater on the right is the K9SI repeater on 444.100 Mhz. This repeater is the Champaign County ARES repeater which runs the weather nets. They also have a weekly Tuesday night net for both ARES members as well as any other hams who wish to check in. (9pm local time)

There are several Android and iPhone apps that interface with the Radio Reference streams. There is one app for iPhone called 5-0 Radio that has my stream available. If you want more details on the stream, here is the link to my feed page at Radio Reference:

If you have any questions about the stream that I didn’t cover, please post them in the comments section. Thanks!

  1. I am currently hosting one stream on RadioReference, the NWS MICRN stream in Iowa. I’ve been streaming since before RadioReference acquired ScanAmerica. It’s definitely well-worth the bandwidth that I wasn’t using anyways since we get a free premium membership, which I use all the time. This spring I’ve peaked at 272 listeners during a severe weather event, and there are more listeners coming to RadioReference everyday, especially with the availability of smartphone apps.

    • Yeah I just paid for 6 months of premium right before I started streaming. 🙂 Every once in awhile I’ll get asked to program someone’s scanner, so it’s nice to have the updated list of frequencies. I do wish one of the smartphones devs would implement a left/right balance adjustment. That way on stereo streams you could completely filter one side out if you didn’t want to listen to it. There doesn’t seem to be that many stereo streams though so maybe it’s not worth the effort.

  2. This is really cool. I’m just getting into the hobby and wanting to participate in Emergency Radio services. I have been looking for a way to listen to amateur radio so I learn what it sounds like. This is great to have on in the background on the iPod Touch using 5-0 Radio here at work. Until I recently joined the Coast Guard Auxiliary, I had never even messed with a two-way radio of any kind. They recommended we new people become amateur radio operators to make our skills sharp, and indeed it has helped tremendously. Notably, the community, people like you, are not at all elitist and welcoming of newcomers.
    Thanks fortaking the time and effort to make this stream available.

    • Welcome to the hobby Dave! I love tinkering with this stuff. Glad you enjoy the audio stream. It’s amazing where technology has advanced to these days, yet ham radio is still working great! Let me know if you have any questions about the stream or ham radio in general. 73!
