ISS packets are coming through the 2M downlink on 145.950 FM interfering with reception of the SSTV and voice transmissions.   There were two ISS packet signals noted on Saturday, August 7 at 1223 - 1243 UTC at AOS - San Luis Potosi, Mexico to LOS - New York/Vermont border. Both packet signals occurred while over the U.S.A.   Not sure if the source of the packet signals are from the 145.800 worldwide crossband FM repeater downlink channel or the 145.990 packet uplink channel.   Mike Schaffer KA3JAW Tampa, Florida EL87SU
