![]() ![]() How do I enable the noise source on the Ham It Up? It is usually used for testing RF gear, or anywhere where you need to inject noise into an RF circuit. The upconverter noise source kit is for a separate wide-band, noise-generating circuit on the Ham It Up PCB. What does the upconverter noise kit consist of? If you do add amplification, we would recommend starting with a small amount, somewhere near 10dB max, as overload can quickly cause problems with performance and can even cause the device to malfunction permanently. Further, the Ham It Up is designed to be near the SDR, and amplification really should be near the antenna if used. Amplification in HF ranges generally causes more issues than it solves. No, there is no amplification on the Ham It Up. Yes, it is bidirectional, so you can transmit and receive on any frequency within range, provided that you have a compatible transceiver, like the HackRF One.ĭoes this device provide any amplification of incoming signal? Is the Ham It Up capable of transmitting as well as receiving? Even on lower frequencies? You can refer to the technical information available on our product page if you're interested in learning more about the upconverter. Yes, this is exactly right all upconversion involves a certain amount of signal loss. ![]() When I run the Ham It Up in upconvert mode, I lose more than 10dB signal strength when comparing to passthrough. You must first switch the upconverter into "passthrough" mode, otherwise you will not be able to receive the signal. If you are tuned to a frequency above this range with the upconverter in "upconvert" mode, it will not work. The upconverter can only convert signals within its upconvert range. It is also important to note the upconvert range of this device (which differs, depending on the version): In order for this to work in your SDR software, you must offset your tuning frequency by negative 125,000,000 Hz (-125 MHz), as described above. When in upconvert mode, it will convert the signal from the antenna up by 125 MHz. When your upconverter is in passthrough mode, it is only passing the signal straight from the antenna to your SDR, with no conversion. My Ham It Up is not working in upconvert mode, only in passthrough mode. +7dBm, which is about 0.5V RMS or 0.7V P to P What is the optimal P to P voltage for the input of the upconverter? For example, if you are trying to tune to an AM radio station like 620AM, you would tune to 125,620,000 Hz (125.620 MHz). Alternatively, you can manually add 125 MHz to your tuning frequency, if you do not wish to use the offset. The LO frequency is 125MHz for all versions of the upconverter, so you will need to use an offset of negative 125,000,000 Hz (-125 MHz) in your software, in order for the signals to be converted correctly. How do I account for the LO frequency in my SDR software? Fire up your favourite SDR software, tune to 125MHz + (+/- the tuning offset from the tuning procedure) + your desired frequency and enjoy!.Plug your USB power source into the USB jack.Ensure your toggle switch is in the enable position.Once you have the SDR working as expected, you can then connect the Ham It Up. We recommend setting up the NESDR first, using our Installation Guide. How do I set up the Ham It Up with my NESDR? What are the differences between each of the models of the Ham It Up?Ī comparison chart of the major characteristics of each model can be seen below. Full product details can be found in the datasheets linked above. This FAQ pertains to all versions of the Ham It Up Upconverter currently available in our webstore - versions 1.3, Plus and the newly released Nano!
