Scottie Globemaster (kit option 4)

Details:

• High power, up to 38 Watts PEP on the HF bands 1.8 - 70 MHz and 2 Watts PEP 144- 1296 MHz.
• A fabulous project for the avid builder, take ownership and enjoy!
• This kit comprises a high quality multi-layer PCB, with immersion gold finish
• Included in the kit is the micro processor with firmware pre-loaded
• With the aid of the detailed Globemaster Reference Manual, and following the step by step build and test instruction sequence, the builder will complete this project with a wide band (1.8- 1296 MHz) Multi Mode SDR Transceiver
• Kit 4 is NOT a standalone transceiver, it requires a host PC to operate
• Reference Manual contents overview:
  • Construction procedure, recommended tools and test equipment
  • Transformer construction and winding details
  • Toroid filter winding details
  • Mechanical assembly details
  • RF PA optimisation
  • Band pass filter response data
  • UHF section components and optimisation
  • System setup notes
  • Driver installation, firmware update and local oscillator setup guides
  • Bill of materials
  • Schematics
• Competence in SMD soldering skills essential (e.g. packages with lead pitch of 0.5 mm and leadless QFN parts)
• Requires metal work skills e.g. accurate drilling, thread tapping
• Ongoing technical support and firmware updates on https://groups.io/g/globemaster
• Strictly in accordance with the EULA an encrypted documentation package will be emailed during the order processing (a password will be emailed separately)

Notes:

1. Please note that aside from the supplied micro processor, the builder must purchase and fit all of the remaining components
2. The builder must procure and fit a Si570 local oscillator as per their requirements. Recommended devices below:
   • HF bands from 1.8MHz to 4m fit Si570BBC000141DG (LVDS 280MHz) - UHF support of 144MHz and 220MHz
   • HF bands from 1.8MHz to 4m fit Si570BBB000141DG (LVDS 945MHz) - UHF support of 144, 220, 430 and 900MHz
   • HF bands from 1.8MHz to 4m fit Si570DBA000107DG (CML 1417MHz) - UHF support of 144, 220, 430, 900 and 1300MHz
3. A suggested supplier for the Si570 device is https://sdr-kits.net/Si570BBC?tag=Silicon%20Labs%20Si570
4. The UHF capability requires the procurement and fitting of components in accordance with the UHF bill of materials
