I've tried to hear NUDTSat several times recently
but I can't hear it at all. Is it already inactive?

2.4GHz Converter2019年11月11日 20時05分

Converter: GRX-2402D (MAKI Co., LTD.)
Receiving : 2400-2402MHz
Converting: 2400MHz -> 144MHz
Interface: NJ connector

  56.4 MHz * 40 = 2256.000MHz
  IF = 2400-2256 = 144.000MHz
       2401-2256 = 145.000MHz
       2402-2256 = 146.000MHz
  H70 x W160 x L200 (mm)
  Gain: 28dB or more
  200mA (+13.8V)

So, I think I can receive 2.4GHz signal,
but not receive 2.2GHz signal.

Mineo,

On many days, only one or two DTUSat-2 beacons at my QTH.

Today, 06-11-2019, first beacon did not transmit until 62 degrees
elevation just before TCA followed by 6 more full or partial beacons.
Yesterday, 05-11-2019, low pass with multiple beacons.

Attachment 1, 05-11-2019 at 5 degrees just before AOS.
              My antennas are only 2.4 meters above ground so signal
              was being received through buildings and trees. 
Attachment 2, 06-11-2019 at 71 degrees. Very strong signal.
Attachment 3, 06-11-2019 at 72 degrees. Very strong signal.
Attachment 4, 06-11-2019 at 52 degrees. Waterfall shows data
              burst after end of CW beacon.

Signal strength seems to be normally good. Beacons are very intermittent.
DTUSat-2 is a great signal to track on 2.4 GHz.

73, Mike (K9QHO)
