Hermes-Lite 2 SDR Project
  Building and using a Hermes Lite 2:
The Hermes- Lite 2 comes as two ready made pcbs incorporating a SDR Transceiver Main PCB, a Low Pass Filter unit and you'll need the case. The Hermes Lite 2 RF power output is rated at five (5) watts. 
I use the following software to operate my Hermes Lite 2, originally developed for the Anan Transceiver range of SDRs: MI0BOT / OpenHPSDR-Thetis software (64 bit) using Protocol-1 for HL2. (see the link below) The PC I use is an Intel Core I9 processor, my I-5, 8th Generation and I-3, 5th Generation also runs it with no problems. The Hermes Lite drives my JUMA PA1000 quite nicely, however, there are other solidstate amplifer kits available, the Hardrock-50 makes a good combination giving 50 watts out, see the link below. Hermes Lite 2 Plus: Upgrading the 'Hermes Lite 2' to the 'Hermes Lite 2 Plus' using the 'Companion Board' all versions:  All the information you require to install the hardware and update the Gateware / Firmware are provided in the link below: "Hermes-Lite 2 Plus Companion Board V3.3 (shown) & 4.0". The difference between these versions is explained in the link. There are different ways to install the Gateware, however, the best way is using an IP interface via the "SparkSDR" software where it becomes fairly straightforward. The functionallity you get once installed and firmware updated is: - CW keyer on HL2 CN4; with keyer, straight and electronic bug key modes - CW Sidetone in local headphones and local speaker - Headphones Jack - Local Speaker Output with 600 mW output capability, good for a laptop type speaker. Speaker (only) mute via repurposed RX Dither SW button - Microphone Jack suitable/configurable for dynamic and passive microphones - Hardrock-50 Power Amplifier Control (bandswitching and PTT) using serial data and PTT connections You can find out all about the Companion Board and the capabilities it adds to the Hermes Lite 2 SDR at the following link: |
