A Canadian satellite known as CASSIOPE will again listen for CW signals on Field Day as it did in 2015 and 2017.
But this time, rather than seeking national publicity, researchers with the CASSIOPE (CAScade Smallsat and IOnospheric Polar Explorer) project are specifically inviting Field Day operators in the Indianapolis area to participate in the experiment. (Hams elsewhere in the Hoosier State may also join in.)
If you’d like to take a shot at having your CW signal picked up by an orbiting satellite, you’ll need to transmit your call sign on a frequency between 7.0075 and 7.0425 MHz during satellite passes at the following times. Since it’s Field Day and the band will be hopping, you’ll probably have to settle for calling CQ and working stations ... or calling CQing stations that are operating in that range. Just make sure to send your call sign often during these timeslots:
June 23, 2018
21:26:00 - 21:38:00 UTC
23:06:00 - 23:18:00 UTC

June 24, 2018
00:48:00 - 01:00:00 UTC
10:24:00 - 10:36:00 UTC
12:06:00 - 12:18:00 UTC
13:47:00 - 13:59:00 UTC
Says researcher Gareth Perry: “You can try transmitting up to the spacecraft during any of these time segments, although I expect that folks in your general area [Indianapolis] will have the best luck transmitting during the passes in bold above. Those are the ones which come closest to you (and the radio receiver is operating).” 
He would like to receive 40-meter log information from stations that transmit in this frequency range during these satellite passes – specifically, “transmission records of those on the 40m band, e.g., which call signs were transmitting at what frequency and what times, then we can try to back out their signals in the post processing.” Send your log info to: This email address is being protected from spambots.
