Changes from V0.6 to V0.7:
The latest 0.7 revision follows the 0.6 schematics more or less, where mostly
mechanical changes are introduced. Following is the detailed list of the changes.
1. The HamGeek mcHF with three boards now, instead of two:
- The RF board host main power supply RF PA, BPFs, LPFs, RX antenna switching, TX preamp and PWR/SWR meter circuit
- RF board PA transistors and low noise linear regulators are mounted flat on the board for full thermal contact with the back of the aluminium case
- Due to much higher real estate on the RF board, all signal flow follows linear path of direction without overlap of low/high energy density fields
- Much more space for expanding the LFP module
- The new Logic board has the bottom side facing the RF board and it is mostly ground plane (except U204 and U207) which removes the need of metal shielding plate
- All low level RF generation/decoding circuits are now moved to the Logic board, bundled with the Audio Codec module
- The LCD is mounted on the Logic board to minimize interference
- All clocks - DSP and RF are grouped to together for minimizing noise and easier temperature insulation, again on the Logic board
- New component: U700 is added on the Logic board to provide RX/TX switching for the RF circuitry, independent of the Audio Codec module signals and at the same time saving extra pin usage from CPU
- The frequency encoder is plugged to P1c connector on the Logic board instead of being soldered onto the UI board
- The UI board uses three general purpose encoders that are vertically (90deg) mounted. Those also have integrated switches
2.The 0.7 revision uses fourteen LED lit buttons, instead of seventeen. The missing three are the encoder mode buttons, their function is now provided by the encoder built-in push buttons
3. The 0.7 revision uses high quality optical encoder (ENA1J-B28-L00064L)
4. With a slightly bigger LCD - the 3.2 inch HY32
