Help Expedition 18 Commander Mike Fincke and Flight Engineers Sandra Magnus and Yury Lonchakov celebrate the holiday season 220 miles above Earth by sending your greetings into space. http://www.nasa.gov/externalflash/postcard/

As I mentioned on November 29, the ARISS team is currently celebrating 25 years of amateur radio operations from space. This e-mail describes some of the planned set of special event opportunities for the remainder of the month of December and the beginning of January.

To date, the ISS crew has configured the radio to support cross-band repeater operations, they have supported some SSTV downlinks and we have had the opporunity to participate in a special test of 9600 baud packet radio operations on the simplex frequency of 145.825 MHz.

This week through December 19, we expect the ISS Ham radio system to be on the 145.825 MHz frequency supporting 1200 baud packet. If PCSAT is configured during the week, double hop APRS is possible.

Hi

I'm having problems to interfece IC7400 with the TNC.
I do receive and decode fine (menu 21 set to 9600),
However there is no audio (data) when key the transmiter.
I already raise the level on the TNC but no joy.
I belive the problem must be on the radio, but I have no idea.
I apreciate any help.
Many thanks in advance
