FO-29 command team says as follows, but now ONLY 'Voice/CW Mode JA' mode in 2003. and the beacon is 435.795 MHz CW. 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 Operational, rotated with analog mode and digi-talker. Inverse heterodyne of FO-29 Uplink Downlink 145.900 --- 435.900 145.901 --- 435.899 145.902 --- 435.898 : : 145.950 --- 435.850 : : 145.998 --- 435.802 145.999 --- 435.801 146.000 --- 435.800 i.e. Uplink + Downlink = 581.800 > What is parameters of beacon modulation. The beacon is CW of the center frequency 435.795 MHz. The width of doppler shift are about +/- 9 KHz (when high elevation) +/- 6 KHz (when low elevation) > What is way to "kill" doppler shift except manual adjustment? When high elevation, about from 435.804 MHZ(AOS) to 435.786 MHz(LOS). When low elevation, about from 435.801 MHZ(AOS) to 435.789 MHz(LOS). > What is data broadcast through beacon? Yes, the beacon is the broadcast signal. > How config the tranciver to recieve the beacon? CW mode (or SSB) > What differences are between beacons of FO-20 and FO-29? The beacons of FO-20 and FO-29 is the same, but FO-20 is stopped and FO-29 is the health. > What antenna? It is to be desired that the directional antennas with pre-amplifier. > What modem is needed to work with FO-29 in Digital mode. Uplink 145.850 145.870 145.910 MHz, FM Manchester Code Downlink 435.910 MHz 1200 baud BPSK Now FO-29 digitalker is stopped. But JARL has officialy announced that FO-29(Fuji-3/Jas-2) is working as digitalker mode 21 - 26 Aug 2003 for Ham Fair JPN. For more information, http://www.jarl.or.jp/Japanese/3_Fuji/dtkit/digitalker.htm but only Japanese language. -------- Subject: Update on FO-29 (JAS-2) From: Emily Clarke Date: Fri, 22 Aug 2003 14:52:53 -0700 Masa, JN1GKZ (whom I worked on AO-40 this morning :-)) wrote me with the following update on FO-29: "FO-29 is now on digitalker mode. Big ham event Ham Fair is held at 23 and 24 Aug in Tokyo. JARL decided to demonstrate FO-29 as digitalker. Many hams who are joining Ham Fair will hear voice from space. It is good opportunity to show the satellite communication world. I'm going to visit Ham Fair tomorrow. There is no plan for digital mode. FO-29 will back analog mode soon at 26th Aug." Masa went on to write: "Special station 8J1HAM will be on from Ham Fair site. But there is no plan on satellite." 73, Emily E. Clarke -------- Subject: FO-29 Digitalker (from Japan) From: "ji1izr/Masahiro Sanada" Date: Sun, 24 Aug 2003 06:39:38 +0900 Hello, everyone. This is JI1IZR/Masahiro from Japan. I attended in the Ham Fair in Japan. JAMSAT members, including me, demonstrated listening to the digitalker of FO-29. About 20 people attended in. They were able to catch the signal from the bird and got the QSL cards. The bird voice is of 'Bush warbler', 'Uguis' in Japanese, instead of cuckoo, the voice of that we can hear at the begining of spring. Japanese likes the voice of the bird because it tells us that spring has come. *************** Masahiro Sanada de ji1izr Hiratsuka-city Kanagawa,Japan *************** > What do FO-29 in Digital Mode What do FO-29 in Digital Mode either forwarding like PACSAT or repeater only. No, Uplink is FM Manchester Code Downlink is BPSK, Now these modem are all sold out, and now ONLY 'Voice/CW Mode JA' mode in 2003.
