The upconverter noise source kit is for a separate wide-band, noise-generating circuit on the Ham It Up PCB. Ham It Up Plus - HF/MF/LF/VLF/ULF Upconverter w/TCXO & Separate Noise Source Circuit 9. up-converter will up-convert / shift-up the incoming lower-frequency signals up somewhere into the dongle's receiving The reference frequency being up-shifted to is called the converter output intermediate frequency (I.F.). Available from NooElec or eBay. It is compatible with any radio capable of 125MHz-190MHz (for full 300Hz-65MHz operation in upconvert mode). Fig 1 Block diagram for the 0 - 50MHz spectrum up 100 - 150MHz converter. 432 MHz to 144 MHz RX Converter - DL9FX So this is pretty much a DC to 6m upconverter. Ham It Up v1.3 Barebones - Nooelec RF Upconverter for Software Defined Radio. When the converter is power-on the <5kHz to 520 kHz band segment is translate to 3.500MHz to 4.000MHz, Model-350 or 4.000MHz to 4.500MHz, Model 400, allowing the reception of VLF . With the converter local oscillator running at 3.5 MHz and a conventional mixer all hell is let loose. ( Article on RTL-SDR Direct Sampling Mode) . I used a NE612 mixer with an si5351 oscillator running at 112.5MHz. A receive only SDR I purchased recently. Fig 1 Schematic diagram of the VHF LO Fig 2 Schematic Diagram of a 759-MHz LO. RTL-SDR dongles only tune down to a maximum of 22MHz, so all the excitement on HF is not accessible. The antenna consists of six 127m high antenna towers placed at intervals of 380m with . The HamItUp V1.2 RF Upconverter works really well and this version includes the 125MHz oscillator so you won't need to use an FM band reject filter that was sometimes necesssary with the 100MHz oscillator. Ham it up, cool. A notch for the LO as well will be the ultimative solution. The original Ham-it-up is an HF upconverter that enables reception of the HF bands with SDRs that do not natively support HF. Recently there is growing interest in the USB DVB-T dongles used as a cheap SDR receiver. The original Ham-it-up is an HF upconverter that enables reception of the HF bands with SDRs that do not natively support HF. Input, output and LO filters reconfigured for substantial sensitivity and selectivity improvements New ultra low-noise linear power regulator (LP5907), with voltage noise under 10 µVRMS! mshuffma971518. There are space left on the PCB for a noise source circuit as additional feature. (See chapter 13. We designed the SpyVerter R2 Upconverter to extend the coverage of the Airspy R2 and Mini series to the HF down to virtually DC with world class dynamic range, frequency stability and sensitivity to rival with high end analog designs at a very affordable price.. SpyVerter R2 builds on top of the successful SpyVerter architecture and improves the key points of high performance HF reception. Simply put, the SDR-100 is light years ahead for weak signals, at the cost of noise pickup. Here is why. N1YWB Ham Member QRZ Page. Ham It Up v1.3 Barebones - HF Upconverter 14 Review (s) Add Your Review A high-quality RF (MF, HF) converter for software defined radio devices like our NESDR series and the HackRF. The VLF-LF_MF Up-Converter extents the range of any shortwave receiver from below 5 kHz to 520 kHz. It mixes the incom- ing signal with the 4-MHz signal from the LO. This builds on the already good version 2 Ham It Up, with useful extras such as the LEDs and fully populated noise source (just add connector and a jumper). Most of the components are already soldered but if you want to use the noise source, than you have to buy the rest of the SMD components required to complete it, which cost additional 15$ including shipping costs. The Nooelec Ham-it-Up Noise Source . Ham It Up, RF, Upconverter, Aluminum, SDR, RTLSDR, 125MHz,NooElec . Major version changes: Proudly designed, fabricated and assembled in the USA and Canada! 144.3 MHz High Selective Converter - DL1LS. Ferrite cores will help only for environmental noise picked up by the antenna. I cannot find on google anywhere that explains how to terminate a AM ferrite coil from a parts AM radio to a Ham It up up converter via a bnc. A well-made-for-the-price H.F. up-converter is the Opendous designed Ham It Up v1.2 - RF Upconverter [2,3]. I'll leave it up on 6 meters tomorrow for a while and try to get lucky on a band opening to get a better feel for performance in that range. Ham Radio Android Software category is a curation of 58 web resources on , My LoTW, Peanut - Ham Radio Digital Voice Client, NCDXF Beacon for Android. Fig 2 Schematic of the 0 - 50MHz spectrum up 100 - 150MHz converter.. For example, 400 kHz incom- Issues. Export to GitHub. Ham it up rf upconverter v1.3 pdf download. 0 is transmitted at a fixed frequency. Nooelec GOES Weather Satellite RTL-SDR Bundle. It's an Aktakom ADS-2061M that was brand new in the box and I got it for the price of a raspberry pi. Software-Defined Radios (SDR) are neat little devices that capture radio signals which are then filtered and decoded by software on your PC or embedded system. Upconverter 125MHz v1.3 - Passive Upconverter Hardware Design for SDR. Most popular among them is E4000. . The Ham It Up Plus is fully assembled in a custom, black, aluminum enclosure, tested, and ready to use. Transmitted an AM signal on 50.125 (YEAH I KNOW, at least I ID'd. Didn't want to overload my dongle by keying up the IC-706) for a couple secs. This dongle is downwards limited to approx. List of changes: Version 8.1.EE: changes of the toggle switch (SW1) on the printed circuit board, now the contacts of the case are soldered to the GND area. Home » Ham It Up v1.3 - Listen to HF on Your RTL-SDR, No case Asembled PCB only (0.5MHz to 50MHz) Ham It Up v1.3 - Listen to HF on Your RTL-SDR, No case Asembled PCB only (0.5MHz to 50MHz) . The previous version of my homebrew RTL-SDR HF upconverter used a Pierce crystal oscillator with a crystal that was marked as 49.8 MHz. At no input the LO is switched off. 100kHz - 50MHz spectrum up 100.1 - 150MHz converter to suit SDR using the Realtek (DVB-T) tuner dongle.. Also works as a panadapter for most radios! It is compatible with any radio capable of 125MHz-190MHz operation (to utilize the entirety of its 100kHz-65MHz frequency range). With as little as an hour of setup, you will be receiving LRIT, HRIT and HRPT GOES transmissions, error-free and with ease . Wikis. Upconverter. The currently used radio spectrum is extremely wide from 3 to 30Hz for submarine communication up to 30 to 300+ GHz or . Longwave receiver converter Figure 13 shows a frequency con- verter front end for a shortwave re- ceiver to receive longwave signals (3%-500 kHz). It is connected between the antenna and a shortwave radio receiver. 144 MHz to 14 MHz RX Converter - DL6HA. The in-line variable attenuator was carefully set so that the reference signal only . 2021.12.16 17:21. Source. Converting A Signal. The Ham It Up Plus Barebones is an HF upconverter that will allow you to extend the range of your favorite radio down to at least 300Hz! Noise source OFF. The latest model of the BU500 has a detection of the input signal from the transmitter. All started with introducing the FCD (FunCube Dongle) SDR receiver capable to receive the frequencies between 64-1700 MHz. kHz up to 4.35-4.5 MHz, enabling them to be received via a shortwave receiver plugged into J1. So I had to think of an "up-converter" pre-stage for the dongle, and found the Nooelec "Ham It Up v. 1.3" that will shift your antenna input up to 125 MHz. PROTOTYPE: A HackRF prototype peripheral with laser-cut acrylic enclosure, telescopic antenna, extra antennas, a Ham It Up RF upconverter, and a HackRF PortaPack will ship in October. . An "upconverter",a "mixer" & a "modulator" are really the same device----the latter term is more appropriate for what you are doing,as the two frequencies are so far apart. Main features: separate large spectrum and waterfall display for input and output signals Converting a 60kHz signal to 3.560 MHz presents no real problem, but consider converting 10 kHz up to 3.510 MHz. We believe this is the best SDR HF upconverter available. HF Upconverter SDR UP-100. I asked for a schematic not a complete product I would have to modify for sma connectors or bnc female to sma male. Original schematic: Basic SDR Upconverter v1.0 Buy SDR receiver: RTL-SDR.COM. all board mounted parts supplied. You need this to receive shortwave broadcast and AM broadcast below 24mhz, When you go below 24mhz you flip the upconvert switch and go to your settings and change the frequency offset to -125000000, and when you go back above 24mhz flip the switch to passthrough and change your offset to 0, recommend getting the enclosure for noise reduction, good product, I like mine.
