One of the best ways to figure out if you'll be able to hear us is to tune to 10.000Mhz and listen for the WWV beacon out of Ft. Collins, Colorado. They're transmitting with 10s of killowatts. If you can't hear them atleast faintly, chances are good you won't hear us.

Hi guys,

I've got my receiver running into Spectrum Lab and uploading screencaps every 5 minutes. It's currently on for testing, but I'll turn it off overnight and then back on at about 0630Z tomorrow morning.

Link2 latest pic, refreshes automatically
Link2 gallery of all screencaps so far

The receiver is tuned to 10.140 USB, and I think Chris will be transmitting with an audio offset of 600Hz, so his carrier should appear at 10.14006 MHz right in the middle of my screen :) I'll hopefully check this with him before I leave tomorrow morning, it would suck to miss the signal by a few hundred Hz.

Nice Steve!

I will be a work tonight, so I will run the stream to 4hv while at work so the admins can set up the rest. Tomorrow September 22nd, I am very busy, but I will be here when the transmittion starts and make shure things are working right and find Chris's beacon location on speclab. Unfortinatly I am connected to a wireless lan network which means the stream can be disconnected and I can not fix it when I am at work. Saturday, I would be going to a ham-fest. What a weekend!

I will be sending the stream at 48kbps. If this is too fast for your ISP, I can send at a lower bitrate.

- but I got noise here in central England.

I never got anything either. There was one signal that I thought was it, until Chris had to shut down his transmitter due to high SWR, and the signal kept right on going on my screen. :(

Note: The info box on my screencaps says "Listening 10.140". I retuned the receiver to 10.139 but forgot to change it!

Steve, you actually did get us very briefly. There was about a 2 minute window where we were able to see a faint signal that was almost certainly us.

We were coming in quite well at ShawnLGs station. Unfortunately we were having substantial antenna problems. Apparently we had a break in the ladder line , and SWR was randomly bouncing from 1:1 to infinite.
