Hello friends,
Some friends wrote that the batteries of the AO-7 will not work. However when analyzing the data made available by Mike in your web site I saw that the results of telemetry for the voltage of the batteries and its load are different in each decoding ... I am convinced that the AO-7 is not in Mode C and would make an appeal to all users of the "Grand Old Girl" using only QRP until your ready reestablishment. Thank you all for answers and guidance. 73' Piraja, PS8RF " Nobody is born knowing " The Amateur Radio is supportive and helpful in any circumstance. > From: jari.koivuri...@aina.net > To: m...@mike-rupprecht.de; ps...@hotmail.com; amsat-bb@amsat.org > Subject: RE: [amsat-bb] Re: AO-7 is not OK > Date: Wed, 14 Apr 2010 17:56:40 +0000 > > > > > > > Hi Piraja, > > > > Yes, I made similar observations.
