Fun with amateur radio #22 USB to RS-232 cable trouble
Just recently purchased a USB to RS232 cable to use my packet radio modem on my Netbook, problem is that rs-232 connection dont seem to carry the complete 5 signal lines, only RTS and DTR well work, the others wont show up!
Anyone out there know of a workaround for this problem?

D Star The future is here ..
The D-STAR is born from a search of the Japanese government pressed ahead with the amateur JARL on how emerging technologies could be used even among amateurs. The result of this research began in 1999 comes to light in 2001 with the publication of the specifications of the system is a digital communication that uses GMSK modulation and the AMBE codec business.
DV Node Adapter to Icom ID-RP2C interface - transmit AND receive.
Another video from the VK5REX D-Star repeater site. Once again featuring my home-brew interface that sits between an Icom ID-RP2C D-Star repeater controller and a DV Node Adapter based GMSK repeater. This video shows my home brew D-Star compatible repeater both transmitting AND receiving using the Dplus software echo function.

Temporary Suspension of SO-67 Service
The Amateur Radio FM transponder on Sumbandila (SO-67) is being temporarily suspended to permit completion of the satellite commissioning activities.
On the AMSAT bulletin board Jan-Albert writes:
There is little more than 6 weeks left in which to complete the outstanding commissioning activities on Sumbandila before operations are planned to be handed over in middle-March to the Satellite Application Center, who will then continue to operate the satellite on behalf of the Department of Science and Technology (DST) - owner of the satellite.
Since our progress is currently hampered by the various SA-AMSAT payload activities, we have unfortunately no choice but to temporarily suspend this service on SO-67. We plan to have it "on air" again end-March / beginning Apr this year.
We have so far successfully executed more than 320 payload activations since we started using the SA-AMSAT payload in Q4 2009.
Thank you for your understanding and patience.
Best regards
