- General
  - Each box will have two inputs (Tx/Rx at IF) and three outputs, like DSP-10
  - DSP-10 block diagram at Figure 2. of this paper.
  - A paper by WW2R with ideas and a better block diagram.

- Transverters
  - SSB electronics has an ad in AMSAT Journal 2003 Sep/Oct p. 23.

- Antennas
  - AzEl
  - Horizontal/linear polarization, no circular unless a clear need is demonstrated and then no switching ditto
  - Gains sized to real estate

- Amplifiers
  - Preamps are needed, most will not be home built since this is not where I want to specialize.
    - UHF preamp design AMSAT Journal 2005 July/Aug p.m 24.
    - When I have a preamp, measure it's noise temperature and gain (Y-method) too.
  - power amplifiers usage minimized
  - tube data sheets
