 ## Resouces:
 [Ian Collings page](https://www.iaincollings.com/)

## Jonny / agenda
- [ ] Assign tasks 
- [x] Export STEP Files of Comms PCB from Altium if possible 
- [ ] Test Hack RF transmit capabilities (need antenna)
- [x] Inspect Hope RF and assign tasks surrounding that 
- [x] Buy new PAs out of pocker (split cost?)
- [ ] Update [Link budget document](https://docs.google.com/document/d/17dYyGCmfhQ2fnWMOki_GLtDPDp1nHwvR8jWn4nhQnIQ/edit?tab=t.0)  
- [ ] Ground station planning
    - [ ] [GS Hw 2022-2023 Roadmap for reference](https://docs.google.com/document/d/1toFLnqjCnisiPKNAtiUGt7f230RoXu8cGjXiNixh480/edit?tab=t.0)

- [x] More hope RFs in the lab box for anyone thats interested 
- [ ] Test Hope RF with ESP32/ STM32 and arduino code  
- [ ] Read Hope RF datasheet
- [ ] Ask Sonia about GitHub for comms
- [x] Apply for Amateur Radio license through FCC for cubesat (or just get my own callsign?)


## Bart
- [x] Read Onboard Antenna datasheet
- [ ] Create doc on "optimal" PCB manufacturing options to select for RF PCB with ibrahim
- [ ] Modulation type study and make a doc for the drive (probably [FSK](https://en.wikipedia.org/wiki/Frequency-shift_keying) or some derivative)
- [x] FCC RF Ham Radio License Process + potential FAA license research process   
    - [ ] Relevant task: figure out FCC limitations on transmittable power (uplink from GS) and create doc on it in drive. ERP (Effective Radiated Power) <= 600 Watts. This is needed because Hack RF SDR max output power is 15 dBm.  
- [ ] Create documentation on your finished comms pcb

## Steven
- [ ] finish xcvr PCB 
- [x] Read Hope RF datasheet
- [ ] LNA for GS
- [ ] PA for GS
- [ ] Calculate Link budget (for reference: 10dB is apparantely fine) https://docs.google.com/document/d/16xCXchDs3DuKU4fw62HMR1535rkSWPAcg9fi7l1BiwM/edit?usp=sharing 


## Ibrahim
- [x] gerber files generation and submission (bom, etc)
- [ ] Create doc on "optimal" PCB manufacturing options to select for RF PCB with Bart
- [ ] More hope RFs in the lab box for anyone thats interested 
- [x] Read Hope RF datasheet
- [ ] Test old comms board (2021 board)
- [ ] Create documentation on your finished comms pcb


## Raiche
- [ ] finish xcvr PCB
- [ ] More hope RFs in the lab box for anyone thats interested 
- [x] Read Hope RF datasheet


## Ann
- [ ] Finish xcvr PCB
- [x] Read Hope RF datasheet
- [ ] Revise Hope RF xcvr PCB Impedance matched trace to antenna
- [ ] Check available pins on Avionics STM32 (i think  we need around 10 pins)
- [ ] Revise MCX connector to vertical connector
    - [x] write trade study document on vertical vs horizontal vs right angle MCX connector 

## Alejandro
- [x] read PySDR 
- [x] Short report about findings on using RTL-SDR
- [x] Read Onboard Antenna datasheet
- [x] Read Hope RF datasheet

## Derick
- [x] read PySDR 
- [x] Do gnu radio demos
- [x] Read Hope RF datasheet 
- [ ] Read Onboard Antenna datasheet
- [x] Read Hope RF datasheet

## Instructions 
    When you finish a task check mark it off so we all are on the same page.
