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.

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.

Nothing heard from it yesterday on a fairly high pass.
Tried both voice & packet on both of the uplink frequencies with no result.

Thanks,
By the time I found and loaded keps I missed it. 20 degree pass too! I’ll be listening for it later. Looks like a41 degree pass tomorrow 13:22.

Just saw this on FB. Apparently the radio payload will be tested this week.

Yes I have the keps on my Ham Radio Deluxe sat program ( now sure from which TLE provider ) and I also see it on http://amsat.org.ar/pass.htm after adding it to the list.
Just had a 9 degree pass but heard nothing. I may just be too early in the commissioning process.
Also it says CW at 120 One Hundred Twenty WPM ? Really ? ………“The data can be received in Morse code format of 120 WPM, at a frequency of 145.9 MHz”

There is confusion regarding the uplink since their website says 437.7 but the coordinated frequency is 437.5.
Since the amateur radio mission is just a payload on a larger satellite, I would not expect any operations from the amateur radio unit in the early part of commissioning the satellite. Hopefully they will provide updates once it is activated.
