RX-Down 145.800 fm TX-UP 437.800 fm I managed to get in to the cross band repeater early and worked M0IKB Angus from Scarbourgh E.Yorkshire from Baildon W.Yorkshire via the International space station 300 miles up in space. Lots of other radio hams can also be heard during the ISS pass over my location. I used a Yaesu FT-847, IOIo beam and SATSCAPE. more info at my site via my Youtube Channel. thanks for watching best 73.
