The cross-band repeater hasn't been on since early October. The 145.825 MHz packet digipeater has been on since then, using the same radio that had been running the cross-band repeater. The cross-band repeater should return sometime in early December, according to ARISS:Looking to confirm the new cross band repeater is active on 437.8??
The radio sounds pretty good. With the new firmware, there are different power levels for different modes - 5W for the cross-band voice repeater, 10W for the packet digipeater, and 25W for the scheduled contacts and other two-way contacts involving crewmembers. Packet has been a lot better with the new radio - improved receiver on the TM-D710G compared to the 20-year-old GE/Ericsson commercial HT, and more power. Five watts from the cross-band voice repeater is easy to hear, even when using duckie antennas. Better antennas help to get through either the voice repeater or packet digipeater, but there's more transmitter power from the ISS than what we have from any of our other satellites.
The voice repeater downlink (437.800) was loud last pass here around 7:20 PM EST.I'm not hearing anything on 145.8 145.825 or 437.8 on a real time pass 70* elevation.
Most of the info you want is listed here --> Contact the ISS - ARISS <--. For the crossband repeater on the ISS, you'll need to program the frequencies as simplex and receive on the UHF frequency and transmit on the VHF frequency listed. Your dual-band radio may allow you to program it as a repeater, but you still won't use + or -, but will have to program the listed UHF frequency for receive and the VHF frequency for transmit. Check your manual to see if your radio allows this. Often it's simpler to use two radios so you can listen while you transmit so you can tell if you are just adding noise to the ISS signal or actually having your signal repeated. The ISS signal is often easy to hear on a handheld, but unless there's very little activity on the cross-band repeater, you won't be able to transmit through it since more powerful signals will simply squash your handheld's signal. Also, don't forget to transmit the proper CTCSS tone when you try to use the ISS cross-band repeater.Do you need to have the frequencies - and + or are they simplex
