How can you actually open a PL tone in ( Mode JA ) using an SSB transmitter ? In my opinion it is best to use a minimum EIRP power on FO-29 to conserve the battery because actually FO-29 along with HO-68 and OSCAR-7 is the best available satellite for linear CW and SSB operation. On FO-29 SSB I worked N2UN in New York from my JN70ES and it was a real thrill to contact Tony with his portable station on a promenade next to the East River. 73" de i8CVS Domenico _______________________________________________ Sent via amsat...@amsat.org.
