I will make a drive out to the Organ Pipe Cactus National Monument, and the rarely-heard grid DM31, next Saturday (2 February 2019). I hope to be out there by 1600 UTC, staying until sunset - approximately 6pm local time, or 0100 UTC. I may try to park on the DM31/DM32 grid boundary for some passes, but more than likely I will be somewhere near the national monument's visitor center - a few miles north of the USA/Mexico border along Arizona route 85. This area is in the northeast corner of grid DM31, Pima County. I will work FM and SSB satellite passes that fall within that timeframe, along with some FalconSat-3 passes.
Being near the international border, coverage by the mobile phone and terrestrial APRS networks gets spotty. I hope to be able to send updates from DM31 using my @WD9EWK Twitter account - visible in a web browser at:
I don't think I will have APRS coverage near the border, but much of my travels next Saturday should appear on APRS as WD9EWK-9:
All contacts made from DM31 will be uploaded to Logbook of the World after the day-trip. If you would like to receive a QSL card for contacts made with WD9EWK in DM31, please e-mail me directly with the QSO details. If you are in the log, I'll send you a card. No need to send me QSL cards or SASEs to get my QSL card.
Thanks, and 73!
