Hi Jeff,

Both ISS and ANDE work fine using HBAUD 1200 U APRS VIA ARISS

- Do not Connect, just go in CONVERSE mode and type for example ":Hello World" - ISS has sometimes delayed transmission - ISS may see a lot of uplinks in parallel, do you have a beam ? - ANDE-1 needs to be 'woken up', send a few packets and then it will reply - I use small doppler compensation A u 145.823 / d 145.827 B u 145.825 / d 145.825 C u 145.827 / d 145.823 (U = TX, D = RX) - 50W is more than enough for ISS, but also sufficient for ANDE - Antenna: I use a 2x6 elements beam (DK7ZB, see my website)

Success & let us know !

Been trying to send a beacon on 145.825 MHz APRS to these satellites with no response ( 50 watts and vertical ) for several weeks now.

Have these satellites been reprogrammed for another protocol or another frequency other than 145.825 ??
