JO-97 Linear Transponder Active

On May 1, 2021, PV8DX reported that the JO-97 (JY1-SAT) telemetry beacon stopped transmitting at 12:57 UTC during a pass over Brazil. After a few days of silence, the U/v linear transponder was reported active over Europe on the morning of May 4th. The telemetry beacon remains inactive.

JO-97’s inverting linear transponder has an uplink of 435.100 MHz – 435.120 MHz and a downlink of 145.855 MHz – 145.875 MHz.

The transponder has remained active in both eclipse and sunlight since May 4th. W2RTV observed frequency jumping while the satellite apparently rebooted in eclipse.

JO-97 is a project of the Crown Prince Foundation of Jordan and was launched on Spaceflight’s SSO-A mission aboard a SpaceX Falcon 9 on December 3, 2018 contains an AMSAT-UK/NL FUNcube linear transponder and telemetry beacon that can also transmit stored SSDV digital images.

DIY-1 Designated DIY-OSCAR 111 (DO-111)

On March 22, 2021, the DIY Satellite Group DIY-1 PocketQube was launched on a Soyuz-2-1a Fregat launch vehicle from Baikonur, Kazakhstan. DIY-1 carries a deorbiting device experiment, and a CW/RTTY/FSK beacon. Further information is available at

At the request of the DIY Satellite Group, AMSAT hereby designates DIY-1 as DIY-OSCAR 111 (DO-111). We congratulate the owners and operators, thank them for their contribution to the amateur satellite community, and wish them a long mission and continued success on this and future projects.

NO-104 (PSAT2) Update

Looks like PSAT2-1 DTMF log shows first 2-way DTMF contact between N3CRT and KN2X QSO numbers 86 and 87.

And a total of 17 unique DTMF users:


Though N3CRT, P3CRT and K3CRT are probably the same person.

Since recovery on 26 April, PSAT2 appears completely healthy.

AMSAT’s GOLF Program is about getting back to higher orbits, and it all
begins with GOLF-TEE – a technology demonstrator for deployable solar
panels, propulsion, and attitude control, now manifested for launch on
NASA’s ELaNa 46 mission. Come along for the ride. The journey will be
worth it!

Upcoming Satellite Operations

N6AJ: FROM DM05 TO EM04, I will be headed to OK from CA around May 17 , DM74 AND DM75 is on the list for sure. I will be on FM and SSB. As it closer I hope to have a schedule.

N9NCY and KX9X will be celebrating my birthday in style in Michigan’s Keweenaw Peninsula, grids EN57 & EN67. Look for us on the birds from July 15-19. Maybe some POTA, too.

W7LT: EN36/37/38/46/47/48/57/58 for late May is on my radar.

Major Roves:
CM93 Possibility: N6DNM Very long shot, but might want to put it on your calendar for May 15th, if you can figure out where it is and for #SOTA folks, that would be W6/SC-336, Santa Rosa Island, activated only once before.
