It also includes a high pass The Hermes Lite 2 N2ADR is a low-cost direct down/up conversion software-defined amateur radio HF transceiver based on a broadband modem chip and the Hermes SDR project. N2ADR filter board. The microcontroller on the board then The Hermes-Lite 2. n2adr_lib Library of useful subroutines used in the above. 0; it provides filters for the TX output to The Hermes-Lite is a low-cost direct down/up conversion software-defined amateur radio HF transceiver based on a broadband modem chip and the Hermes SDR n2adr-sdr@groups. n2adr_basic Very basic example. In the picture below, look at For the three-pin header you need the same size as the 1x20 header on the main HL2 board. On my HL2, the total height is 11. The documentation is here. The PC running the SDR software sends the transmit frequency to the board. PC-based audio which can use headphones to Problems of connection with Hermes Lite 2 1 - 11 of 11 1. It is an entirely open About N2ADR HPF & antialiasing lpf for the Hermes Lite V2 project (fork heavily modified) The N2ADR filter board is designed to work with the Hermes-Lite 2. The pin pitch is 2. Can someone give a "step by step" procedure? Perhaps a schematic showing the Here is why I chose the Hermes Lite 2 (HL2) SDR ham radio transceiver as my main rig in the shack even if it is QRP. Software will provide a mechanism to set the J17 encoding Setup Program by James Ahlstrom, N2ADR The current version is 1. Using the Open Collectros settings on the phpsdr software, (Menu->OC) you can select The N2ADR filter board is designed to work with the Hermes-Lite 2. com. 0 main board, the N2ADR filter companion board, and the recommended enclosure with end plates are available as 3 separate If so, does the n2adr_ioboard. It also includes a high pass filter to For builds that use the N2ADR companion filter card, a single row header as pictured in the next section. This board connects to the Hermes Lite 2 and is mounted above the N2ADR filter board. The pins are square and 0. I did not understand what is needed to get the N2ADR board to work. HiQSDR is the further developed version of the DDC/DUC frontend from Jim, N2ADR. Measure Board. io/g/n2adr-sdr. The filter board is controlled by an I2C interface and can be The HL2 main board must be modified by adding three extra header pins. I have generated an assembly BOM that includes only components to be assembled in China. 64 mm on a side. io Group Description This group is about the software defined radio software "Quisk" that was designed by Jim, N2ADR. It provides switches to control attached relays, antennas and n2adr_test Test program to toggle the 5 volt outputs. Audio Amplifier. 05 mm below the PCB. Please direct question The Hermes-Lite 2 support page is here. See the N2ADR comapnion filter card section for The Hermes-Lite 2. N2ADR designed a filter board that adds transmit low pass filters and a receive high pass filter to the Hermes-Lite 2 software defined radio. Support The main group for Internet support is https://groups. The N2ADR filter board for transmitting with the HL2 is also available on You can use a kind of N2ADR lpf controller, based on the right I2C driver -or- Arduino based ones. 3 from March 2019. Using the Open Collectros settings on the phpsdr software, (Menu->OC) you can select A second generation low-cost amateur HF software defined radio transceiver. The Hermes-Lite 2 can be used with Quisk, PowerSDR, Spark SDR and other software that understands the If the correct pattern is not already setup, press the N2ADR Filter button. This will select the correct sequence for the N2ADR board. The N2ADR filter board is now working with my BOM database and generation scripts. - softerhardware/Hermes-Lite2 This board connects to the Hermes Lite 2 and is mounted above the N2ADR filter board. Based on the original design Jim developed for his nice SDR software quisk, The board mounts above the N2ADR filter board in the same box as the Hermes Lite 2. You can use a kind of N2ADR lpf controller, based on the right I2C driver -or- Arduino based ones. But my HL2 is an old one, so check what size your pins are. It provides switches to control attached relays, antennas and power amplifiers. Thes pages contains some measurements on the TX and RX sections of several version of The Hermes Lite 2 N2ADR is a low-cost direct down/up conversion software-defined amateur radio HF transceiver based on a broadband modem chip and the Hermes SDR project. Search for "Hermes Lite 2". OK! I have a N2ADR board in my hand. I follow this project since 2010 now. 62K subscribers Subscribe More information about the group buy available on the Hermes Lite 2 Wiki. FPGA-Generated Power For example, the N2ADR filter board splits these bits into 7 groups for 160M, 80M, 60/40M, 30/20M, 17/15M, 12/10M and AM blocking HPF. 1Gbps standard ethernet interface to host computer to support wideband data and multiple receivers. 43 mm with 3. Setup|General|PA Control|PA The Forward / Reflected Power Board measures Peak forward power. pyw script do this? My second question: does the IO board provide any impedance matching or buffering to remove the RX loading issue we see when using RF3 Hermes-Lite SDR v2 The original Hermes-Lite prototype has evolved into the Hermes-Lite v2. 54 mm. n1adj_hr50 Control the Hardrock-50 amplifier. What You Need Steve kf7o added this information (May 8th 2020): I've received several inquiries about what exactly is need to finish or use the HL2 if Onboard 5W PA. This page describes how to use some of these options. The exac James Ahlstrom, N2ADR, has developed a filter board that can be easily connected to the Hermes-Lite 2. 0 and provide required low pass filtering for transmit. 0 includes additonal hardware options on the main PCB.
