Bummer! I was really looking forward to having three more FM birds (CAS-5A, CAS-7A, and CAS-7C). -David, N9KT

CAS-7A Delayed
#CAMSAT says CAS-7A launch has been postponed until next May, and CAS-5A until next June.
“Because of COVID-19, many things have been delayed,” CAMSAT’s Alan Kung, BA1DU, told ARRL.
An announcement will be made closer to launch date.

Now the $5 question: Is it coming from the Russian module (like in the past) or is it with the new Kenwood radio from the Columbus module? Stefan

Possible SSTV projects from the ISS coming - receiving their wonderful images can be VERY simple! Check out ...

Re: AMSAT-NA's LIVE OSCAR Status Page

Using and entering YOUR pass data for the ISS’ new crossband repeater is VERY useful - especially since it is turned OFF for ARISS events, and when missions approach/leave the ISS.
It will be turned off approx 0900 UTC this Monday to support an ARISS contact.

ISS Crossband Repeater - What a Month!
Clint Bradford
Just a thanks to ARISS Dave and Dave, Kenneth in Houston, Gordo and Chip in Orange
County, CA, and to Marvelous Rosalie for ALL the work getting our new asset up and running and ham-tested! AND - OF COURSE - THANKS to ALL the hams and their signal reports! From the ARISS team - This project of the InterOperable Radio System (IORS) was launched from Kennedy Space Center on March 6, 2020 on board the SpaceX CRS-20 resupply mission. It consists of a special, space-modified JVC Kenwood D710GA transceiver, an ARISS-developed multi-voltage power supply, and interconnecting cables. The design, development, fabrication, testing, and launch of the first IORS was an incredible five-year engineering achievement accomplished by the ARISS hardware volunteer team. It will enable new, exciting capabilities for ham radio operators, students, and the general public. Capabilities include a higher power radio, voice repeater, digital packet radio (APRS) capabilities and a Kenwood VC-H1 slow scan television (SSTV) system. A second IORS undergoes flight certification and will be launched later for installation in the Russian Service module. This second system enables dual, simultaneous operations, (e.g., voice repeater and APRS packet), providing diverse opportunities for radio amateurs. It also provides on-orbit redundancy to ensure continuous operations in the event of an IORS component failure. Next-gen development efforts continue. For the IORS, parts are being procured and a total of ten systems are being fabricated to support flight, additional flight spares, ground testing and astronaut training. Follow-on next generation radio system elements include an L-band repeater uplink capability, currently in development, and a flight Raspberry-Pi, dubbed “ARISS-Pi,” that is just beginning the design phase. The ARISS-Pi promises operations autonomy and enhanced SSTV operations. ARISS is run almost entirely by volunteers, and with the help of generous contributions from ARISS sponsors and individuals. Donations to the ARISS program for next generation hardware developments, operations, education, and administration are welcome -- please go to https://www.ariss.org/donate.html to contribute to these efforts. /end/

Re: Operating tips
Arup
David,
Yes, I do need to turn the squelch off. I thought it was weird that the Yaseu FT-71 was so quiet with the squelch "off". My baofeng did have the white noise. Somehow I was able to get a good recording of PO101 in the middle of the afternoon over the weekend even with the squelch on! Turns out I just turned the "squelch threshold level" off. As a new ham I don't fully understand the difference between "squelch" and "squelch threshold level", but turning the "squelch" off will definitely help in my endeavors. And thank you for the advice.

Arup- One thing about your recording. Mine always has constant background hiss because my squelch is wide open. When you are working the sats, you should have your squelch wide open. -David, N9KT

Off hours is definitely the key. I'm a night owl, so I concentrate on passes from 10pm - 1am. I've been able to make up to six contacts in a pass! During the day, I'm lucky to make one. -David, N9KT

Operating tips
Arup
Hi All,
I've attached my recording of the ISS pass tonight at 22:39z with a max elevation of 57 degrees from FN01. A few questions 1. Can anyone offer tips on how to work a "smoother" pass? As you'll notice if you listen to the recording I often can only hear the call or grid, but not both. As such I'm hesitant to key-up and attempt a contact. I do have the doppler shift programmed in to the memory. I start at 437.815 and go down to 437.785 by 0.005 MHZ and I try to follow the path of the pass using SatSat and the compass on my phone. 2. Is the choppiness due to being in a mountainous area? Or are people "stepping" on each other? Arup KE8OTP
