Meteor-M N2-2 Weather Satellite Updates: No More 137 MHz LRPT, L/X-Band Working in Daylight

In late December 2019 we posted about Russian weather satellite Meteor M N2-2 which had unfortunately been struck by a micro-meteorite on Dec 18, causing it to lose control and go offline. Meteor M N2 and N2-2 satellites are often monitored with RTL-SDR dongles as it is relatively simple to receive their LRPT signal at 137 MHz which contains a high resolution weather satellite image.

Recently Happysat updated his Meteor M status page, noting that Meteor M N2-2 has been partially recovered, but due to low power it can no longer transmit a 137 MHz LRPT signal ever again. However, the L and X-bands are transmitting while the satellite is in daylight. Happysat writes:

January 2020 There will be only short-term power-ups in the radio visibility zone, and the battery life will be reduced tenfold.

Of particular concern are the batteries they are very quickly overheated and switching from regular to backup.

Unfortunately the power supply features do not allow the 137 MHz transmitter to be used in abnormal power, mode (from solar panels) which is used now although technically it is working fine.

There will be no LRPT Transmission's anymore.

The older Meteor M N2 satellite remains operational transmitting at 137.100 MHz.
