● (No.298) FO-20, 29 の現状 (2001年 12月10日) --------------------------------------------- FO-20 is now in mode only mode JA continuously, not mode JD. JAS-1b (FO-20) Voice/CW Mode JA Uplink 145.900 to 146.000 MHz CW/LSB Downlink 435.800 to 435.900 MHz CW/USB FO-20's beacon signal is now weakly transmitting as only carrier at 435.795 (+/- doppler). FO-29 is now working as mode JA from 4 Dec 2001 through 31 Mar 2002. JAS-2 (FO-29) Voice/CW Mode JA Uplink 145.900 to 146.000 MHz CW/LSB Downlink 435.800 to 435.900 MHz CW/USB Operational, rotated with digital mode and digi-talker. Digital Mode JD Uplink 145.850 145.870 145.910 MHz, FM Manchester Code Downlink 435.910 MHz 1200 baud BPSK Digitalker 435.910 MHz Callsign 8J1JCS Operational, rotated with analog mode and digi-talker. FO-29 is now working as mode JA, so we can hear CW beacon at 435.795 (+/- doppler). We can analyze these CW telemetry with "fo29cwte" program which is posted at the URL below. When FO-29 is working as mode JD (maybe 2002), we need to use the TNC for JAS mode i.e. Up: "FM Manchester Code" and Down: "BPSK" such as TNC-241 or TNC-555 (TASCO JAPAN). Unfortunately these TNC are not sold now. We will be announced the operation schedule of FO-29 by JJ1WTK, Kazu Sakamoto on AMSAT-BB. ---------------------------------------------- Name : Mineo Wakita / JE9PEL, JAMSAT member Mail : ei7m-wkt@asahi-net.or.jp URL : http://www.ne.jp/asahi/hamradio/je9pel/ QTH : Yokohama Japan, GL:PM95TJ Date : Dec 10, 2001 ----------------------------------------------
