Barely Works Technology
70 cm Development Page

Steps:
- Draw a block diagram, post it here.  Each block is a step.
- Work out the Rx/Tx interface details to DSP-10 carefully.
  - This needs to be right since it will be the precedent.
- Make tentative parts selections.
- Do pic development (or equivalent) based on the needs of those parts.
- Construction may be on a bare board, bug style, to eventually go in a box.
- Build a 576 MHz / 5 = 115.2 synthesizer that references 10 MHz.
  - Needs to be tunable in 200 KHz steps.
- Build X 5 multiplier so as to have 1 MHz tunability at 576 Mhz.
- Build a 432ish low noise chain with filters and amps.
- Build a mixer and get reception to 2-meters.
- Build a transmit chain with filters and amps to about 2 watts.
- RF Switching
- Control software, both ends
- Build the 2 in 30 out amplifier under the desk.
  - or consider other amplifier options.
- 70 cm beam, 440-18 beam stack, corner reflector, dish feed, something
- Hardware Quals.
- Build a 300 W out amplifier.
