Decent pass on the ISS this afternoon. I thought I made 2 contacts however John – KE9FF is operating under an expired license, and the K15IP station does not exist.

Great pass this morning for SO-50. Made a few new contacts before the storm rolled in, Steve – W15D and Ralph – KA0JMK. It sounded like Ralph – KA0JMK did not have his receive frequency correct.
Sorry Jason, W3ALT for getting your name wrong, it was good to hear you though, QSL my friend.

Great pass today on the ISS, a lot of static though. I did not begin to receive any audio until the ISS was approaching max elevation. However I did receive one contact with James- WD5GRW from Allen, Texas – thanks James.

Here is a recording from yesterday, 2026-05-14 of the downlink audio from the ISS. This is my first pass with the ISS and I decided to just listen. Good job to my friend Andy – KE7RTB from Huffman Texas for making multiple contacts while I was monitoring.
Be patient with the recording, there will be a pileup at around 01:55.
With this pass I used my ICOM ID-52A to record the downlink audio.
ISS Uplink 145.990 / 67Hz
