FYI, The IARU has coordinated these frequencies for Diwata-2: – 145.900 MHz downlink – 437.500 MHz uplink
Diwata-2’s Amateur Radio Unit Diwata-2’s Amateur Radio Unit (ARU) operates in two possible modes: FM voice repeater (FMVR) mode, and APRS-based digital repeater (digipeater) mode. The uplink and downlink of these modes are implemented at 437.7MHz and 145.9MHz respectively. The following lists some information that may be useful when utilizing the radio’s services.
Telemetry Formats
The Diwata-2 amateur radio unit (ARU) provides telemetry data in two forms depending on its operational mode: CW (enabled in ARU voice repeater mode), and FM (enabled in ARU digipeater mode. As the two operational modes are scheduled according to the day of the week, the available telemetry differ in format and content correspondingly. This section explains the data format and specifications for the ARU telemetry.
Continuous-wave telemetry (CW)
The CW telemetry is available when the satellite is in voice repeater mode. The telemetry messages expected from the ARU will be sent every 1 minute, when the ARU is idle, i.e. there are no ongoing voice operations. This said, the telemetry will not be available when the ARU is busy, and likewise, the telemetry transmission will be abruptly aborted when a voice repeating operation starts while in the midst of telemetry downlink. The data can be received in Morse code format of 120 WPM, at a frequency of 145.9 MHz. The pertinent data format is shown below, and further explained in the table that follows.

Hello all,
Has anyone heard this new sat beacon ?
I get only a few daytime passes a day here on the east coast and have not been at the rig during those passes.
