Dear LF, Now (19-30Z) I start the recording of the band 137690-137790 with frequency expansion ratio 20. It works nice! I have record an audiofile of 8 hours last night wich is 24Mb length only (it i
Dear LF, I will observe around 135922 next night. Please any QRSS120/60 beacons. Unfortunely this frequency is noisy here usualy. But some times it is clear. 73 de RA9MB/Alex http://www.qsl.net/ra9mb

Dear LF, last night I have record sigs arround 135922 by my sound preprocessor with time_compressing/freq_expansion factor of 200. Plaing this record audible I have nice hear YU7AR. Thus QRSS120 can
Hi Uwe, DJ8WX will be on the air agn the next nights. Seems I have see Your sigs. But too weak, only 'D' and 'X' is decodable realy. 73 de RA9MB/Alex http://www.qsl.net/ra9mb

Dear Alberto, Do really exist A/D converters capable of 24-bit resolution at 30 MHz bandwidth ? Why one need 24-bit? Though 16 bit is adequate for most SW,MW,LW recievers. 16 bit yelds abt 90 dB dyna
Dear Alberto, I am not quite sure I do agree with you. While it is true that narrowing the bandwidth the energy of the noise inside that bandwidth do decrease while the signal doesn't (provided it is
