Stuff to buy:

at Mouser or Digikey:

at Amazon or Aliexpress

  • EDUP BE-003 PA
  • POE+ injector
  • USB ethernet dongle
  • POE+ to 12 V and 5V
  • BIAS-T
  • 60 cm (or bigger) satellite dish

Things to do:

  • The old IPB cable going from the basement to the top of the build is no good anymore. We need to take a new cable and run it from the basement to the top.
    • Why an extra cable? Because I case of emergency we can simply cut the power to everything and the transmitter will stop sending.
  • Install sat dish

charly und ich waren heute auf dem Dach. Sicht zum Satelliten Es'hail 2 ist frei.

230V-Strom ist nicht mehr aufgeschaltet auf dem Dach.

Das Dach ist nicht mehr verschlossen.

Der DX-Patrol-GPSDO kann leider nur einen 10 MHz-Takt ausgeben. Um mit dem ADALM-PLUTO kompatibel zu sein, braucht man wohl 25 oder 40 MHz.

Zitat:

"Note: on the Internet you can find many reports that operation with 10 MHz is not possible, and only
works from about 13 MHz. In my tests, I could confirm this in the meantime. But even with 13 MHz the
PLL in Pluto was not always stable. Only from 20 MHz (up to 80MHz) trouble-free operation was
possible."

Sehr ungewöhnlich, 10MHz ist eigentlich standard als Referenztakt...
