Notes from PSWS / TangerineSDR call of 06-17-2019.

1. The GPS antenna current limit on the M8F does not sufficiently limit the
current during an antenna short. The bias-T internal to the M8F will burn
out under that condition. Need to implement external short protection.

2. Some on-line component pricing websites:
   * Scotty WA2DFI: https://www.eciaauthorized.com/en
   * Rick W2GPS: https://octopart.com/

   * Rick W2GPS: Dual Frequency (GPS) Antenna:
       https://www.crowdsupply.com/amungo-navigation/nut2nt-plus

3. Looking for a $15 price range VCTCXO with adequate stability for the
project.

4. Still need information about magnetometer circuit board availability,
electrical interface.

5.  Scotty discussed the possibility of adopting some of the HPSDR Protocol
2 in terms of discovery, capability, control, and communications. Will need
to discuss this with Bill when he returns. Scotty looking at documenting
this.

6. Dave is looking for information on the MAX10 FPGA in order to be able to
modify his OpenHPSDR FPGA downloader for TangerineSDR.
