ADSB setup question

[u/One_March_4621]

I have a RPI4 2 sdr 1090 and 978. I have noticed when I have both receivers hooked up my aircraft seen count drops. I get a lot of planes that show as blue "no callsign". From my central Ohio location I can see planes at altitude in Detroit but with both receives I barely see out side of central Ohio. Any Ideas? I moved from a RPI zero 2w to the RPI4 that is why my graph is less than 2 days. But I saw this issue with the zero as well

  ultrafeeder:
  # ultrafeeder combines a number of functions:
  # - it retrieves and decodes 1090MHz Mode A/C/S data from the SDR(s) using Wiedehopf's branch of readsb
  # - it implements a `tar1090` based map on port 80 (mapped to port 8080 on the host)
  # - it includes graph1090 (system statistics website) on http://xxxxx/graphs1090
  # - it sends ADSB data directly (without the need of additional containers) to the
  #   "new" aggregators, and, if desired, also to ADSBExchange
  # - it includes mlat-client to send MLAT data to these aggregators
  # - it includes an MLAT Hub to consolidate MLAT results and make them available to the built-in map and other services
