And just like that, the APRS Digipeater on the ISS is back online!

Another great write-up from Daniel Estévez - 9k6 downlink from Z-Sat! Almost, but NOT QUITE enough SNR here for a completely '0' output stream, but fun to try. destevez.net/2025/06/z-sat-…

Successful ISS crew contact w/ India via K6DUE as the station passed over Central Canada, Great Lakes, & the Eastern U.S. this morning! Downlink audio (gaps removed) --> qsl.net/k/k4kdr//audio…

Very busy Tevel2-3 pass w/ the FM Repeater active over the Eastern U.S. 'Some' of the audio seemed to overpower the sat's RX... David 4X1DG - should FM-narrow be used on the 2m uplink? Full audio -> dropbox.com/scl/fi/sm28lmy…

Despite low-elevation at start & end of this evening's ISS pass, the hydrasdr.com RFOne did a fine job w/ the PD120 SSTV! (demo unit appreciated! Finding no issues & loving the solid USB-C connection)

Possibly my first noise-free SSTV image! PD120 from the ISS this evening on a 74° EL pass over the Eastern U.S. Like a mis-struck coin, is this picture more valuable because the caption is wrong?

ISS APRS Alert: as of the 0130utc pass over the NE U.S., digipeater was active on 145.800 MHz. Due to low EL, did not decode any of my digipeats absent bit errors. So, you won't see me on ARISS.net

Finally a high enough pass for me to join those who have decoded the 9k6 downlink from 'REAL' on 450.060. But even cooler was catching the S-Band downlink on the same pass, including data sidebands! Will use better S-Band settings in GQRX next time to improve resolution

Despite a 1M dish that needs better alignment & a blanket of leaves on the trees, I finally managed to see the S-Band HamTV downlink tonight! Hope to see an image one of these days if I can improve SNR. ARISS - Amateur Radio on the ISS

9K6 FSK packets from Robusta-1E (ENSO) decoding nicely in GQRX over the Eastern U.S. Now the wait is on to see what the "guess who" hints look like!

Decoded TUSUR-GO Image data 23:18UTC pass over Japan using Geoscan V2 Decoder.

Got to love meteors - I hear a 6-meter MSK144 station in Georgia & try to reply... only to get a bounce up to New Hampshire & New York! At least there are a few showing up

Powerful UMKA-1 finally transmitting this weekend's SSTV for 'Space-Pi' over areas other than Asia!

Even w/ noise as EL got lower towards end of pass, very cool SSTV image from ArcticSat-1... appears to be a shot from the on-board camera! 0205utc just off the U.S. Atlantic Coast

Meteor Scatter to Europe?? I didn't know that was a thing. Ok, then... antenna rotated!

Incredibly strong 1k2 / 2k4 signals continue from NUSHSat-1 w/ short interval to make doppler tracking super-easy. Other satellites are like, "I'll have what she's having"!

Meteor-M2.4 LRPT first look here at Category-5 Hurricane Erin in the lower-right corner of the image! RX, decode, & images all via SatDump w/ the hydrasdr.com RFOne

Oh my! Best ISS HamTV S-Band signal so far. No lock in SatDump, but hopefully close enough to decode something when the leaves fall off the trees. 1-meter mesh dish w/ Kuhne downconverter to hydrasdr.com RFOne

Combo dial-up style BBS & Meshtastic LoRa node! Thanks KM4ACK for great how-to (youtube.com/watch?v=knJzfD…). No one in-range consistently YET on 906 MHz, but building stuff is fun regardless. 6Ah LiFePO4 should run a Pi-Zero2W & Heltec-v3 for... I'll have to let you know!

This could be fun after launch to the ISS & deployment... Ten-Koh-2 w/ a linear transponder -and- a 5 GHz beacon!
