Japanese radio amateurs ask for reports of Z-Sat

Yasutaka Narusawa JR2XEA of the Komaki Amateur SATCOM Club reports the satellite Z-Sat is planned to launch on an Epsilon rocket at 0048-0059 GMT on October 1. It will be sending CW on 145.875 MHz.

On the AMSAT Bulletin Board Yasutaka JR2XEA writes:

Komaki Amateur SATCOM Club has an amateur radio station in Komaki City, Japan.

The 50 kg class infrared observation microsatellite “Z-Sat” developed by Mitsubishi Heavy Industries will be launched by the Epsilon rocket on October 1st.

After satellite separation, Z-Sat will start transmitting CW beacon of VHF band.

The beacon signal is in Morse code and contains information such as satellite battery voltage.

This information is very important as survival information immediately after the satellite is put into orbit.

Therefore, if you can receive the beacon signal from the satellite immediately after the satellite launch,

We would appreciate it if you could report it.

Komaki Amateur SATCOM Club’s Twitter is open at the following address. Information on Z-Sat transmission frequency, data format, orbit TLE, etc. will be released in the future.

We look forward to your attention to Z-Sat.

New EMF Regulation and QO-100 satellite / Microwave operation

Ian GM3SEK is giving an online talk on the application of the RSGB-Ofcom Calculator to Microwaves and QO-100 satellite operation on Saturday, October 16, at 1230 GMT (1:30 BST)

John G3XDY, Secretary UK Microwave Group, writes:

As I expect you are aware, UK stations must have Electromagnetic Field (EMF) assessments in place for operation above 110 MHz from 18th November 2021. Some RSGB guidance on EMF is here:
https://rsgb.org/main/technical/emc/emf-exposure/

The RSGB has been developing a tool that incorporates the Ofcom EMF Calculator but extends the models to include single and multiple Yagis plus various sizes of dish antennas, and takes account of the directivity of the antenna.

Ian GM3SEK, a key member of the team that developed the spreadsheet tool, will be talking about its application to Microwaves and QO-100 operation on 16th October at 13:30pm, in a joint BATC/UK Microwave Group presentation during the BATC Convention.

Registration is not required, to view the talk just go to https://batc.org.uk/live/cat21

Full details of the BATC CAT21 program are available here
https://forum.batc.org.uk/viewtopic.php?f=135&t=7609

This is an important topic for all that operate on VHF and above, and Ian will dispense invaluable practical advice on how to assess your dishes and Yagis in the microwave bands. Not to be missed!

FUNcube-1 (AO73) returns to full sunlight and continuous telemetry mode

After a few months of normal eclipse periods, FUNcube-1 (AO73) will, next week, re-enter full sunlight from next week for a period of approximately two months.

As we have been in continuous transponder mode for some time now, we have decided that, during this sunlight period, FUNcube-1 should operate in continuous high power telemetry mode. The change will be made within the next few days.

FUNcube-1 has now been in orbit for almost eight years and the telemetry indicates that all systems, including the battery and solar panels appear to operating as well now as they did immediately after launch!

GENESIS satellites to launch

AMSAT-EA GENESIS Satellites

After a year waiting, finally this Friday, September 3, at 01:00 UTC the digital GENESIS satellites are expected to launch from Vanderberg AFB aboard Firefly’s Alpha rocket in its maiden flight.

These satellites are ASK (OOK) and CW repeaters. They transmit a lot of telemetry and also 19 different CW greeting messages in English and Spanish.

We would like to ask you all to please try to receive them as any information about their transmissions would be very valuable for us. These are the first satellites we build by ourselves and we need to learn everything we can of them. Waterfalls, audio USB receptions or IQ files would be very appreciated. Please send them to genesis@amsat-ea.org or to ea4gqs@amsat-ea.org. We will send you a nice QSL.

Initial keplerians are listed below. We expect to provide accurate ones a pair of days after the launch.
