Looking for Airspy Mini and R2 users

SatNOGS Software

Good day,

Thanks for taking the time to look at this topic.

I am looking for ground stations that upgraded to Bullseye and satnogs version 1.8.x. and use an Airspy SDR, I want to compare them and see how they perform.

Currently my ground station 1466 is using a R2 and 2173 a Mini.

Here the settings used by these Airpsy SDR’s.

1466 Airspy R2

SATNOGS_STATION_ID="1466"
SATNOGS_SOAPY_RX_DEVICE="driver=airspy,biastee=true"
SATNOGS_RX_SAMP_RATE="2.5e6"
SATNOGS_GAIN_MODE="Settings Field"
SATNOGS_OTHER_SETTINGS="LNA=12,MIX=8,VGA=11"
SATNOGS_ANTENNA="RX"

2173 Airspy Mini

SATNOGS_STATION_ID="2173"
SATNOGS_SOAPY_RX_DEVICE="driver=airspy,biastee=true"
SATNOGS_RX_SAMP_RATE="3e6"
SATNOGS_GAIN_MODE="Settings Field"
SATNOGS_ANTENNA="RX"
SATNOGS_OTHER_SETTINGS="LNA=12,MIX=8,VGA=11"

Thanks in advance.

I’ve been battling a rotator issue all weekend so the past couple days have poor performance-wise but page 5 -10 of my observations reflect the average performance with the specs/setings above

Looking at your observations I also see similar behavior as what I experience.
Can you compare them to a moment in time when you used a older software release?

Here two obs from the same satellite with a 1.7 and 1.8 client.

PICSAT version 1.7 SatNOGS Network - Observation 6630307
PICSAT version 1.8 SatNOGS Network - Observation 6647997

Sure, here you go

Looks like I made a switch from satnogs-client v1.6 to v 1.81 on Sept 21 @ 23:34 UTC, pretty sure I i went from buster → bullseye in August

TIGRESAT v1.6 observation middle of page 132 is where client version switch happened (3 failed obs in a row).

TIGRESAT v1.81 observation from a few days later

Hope this helps
