The new USB disk worked just fine and I was off using Pentoo. I went to Target, bought a stack of DVDs and another USB disk. iso image on the USB drive, no matter how it was formatted. The Pentoo derivative of Linux downloaded just fine, but I could not get it to load the. This week my goal was to start transmitting. I wanted to get through the tutorials on, but one of the first challenges was getting a Linux operating system up and running. Last week, I was able to get HackRF One receiving using SDR Sharp software. This entry was posted in HackRF One on Octoby jajack585. Until then, I have something that works just fine for my simple experiments and testing. As I learn more I am sure I will eventually figure out filtering. So I deleted many features I cannot yet explain, and everything still works. My overall philosophy has been to use the simplest flow graphs possible. While Clayton had filtering in his flow graph, I don’t know how it works. Others familiar with SDRs might comment on my lack of filtering. Next steps will be some mobile testing of range on different antennas. However when 100′ away from the transmitter, the low level carrier is not noticeable.

Close range testing produces a subtle carrier at all times followed by the full scale carrier when the HackRF is “Keyed”. So far, testing on 6m and 2m has turned out just fine. When executed, the GUI chooser provides the following options: This is multiplied by a cosine wave to provide something resembling an analog signal and then “upconverted” to the sample rate compatible with the hardware.
##6 HACKRF ONE CODE#
The speed of the morse code can be changed by adjusting the repeat interpolation value. Since a series of 1’s and 0’s can be processed so fast that its not audible, each piece of data is repeated 5000 times.

Spaces between the dits and dahs of a character use a single 0 and spaces between characters use three 0’s. Dits are represented by a single 1 and a Dah is represented by three 1’s in series. So how does this work? The Vector Source contains a pattern of 1’s and 0’s that match the pattern of the international morse code for the letters being sent. By extracting out the CW transmitter and only including blocks that were absolutely necessary I was able to make the flow graph shown below: Clayton had developed a GNU Radio Companion file that contained transmitters for pretty much all the modes. Ryan was aware of what I was trying to do with the HackRF and knew that Clayton would be able to help. I was introduced to Clayton Smith by Ryan Tucker. I admit that some of the formal topics were a bit too much for a newbie to grasp, but the conversations in the hallway and hospitality room were worth the price of admission.

The Microwave Update conference in Rochester was a great time.
