Gentlemen,

This is a new satellite from South Africa. It has a VERY strong downlink, easily copyable on an unsquelched HT. Take a listen at the UTC times listed for USA (East) below, starting at about 435.355, and tuning down through 435.335 by the end of the pass. I'd recommend listening to a pass to get the hang of things before trying to transmit, and use narrow FM or speak softly on the uplink. I'll be happy to field questions about satellite related stuff, and invite everyone interested in AMSAT to join us on the NI4CE system Thursday nights at 730PM for the Florida AMSAT net.

73, Drew KO4MA

Hello

It will be a busy weekend on SO-67 as we intend to schedule the FM V/U cross-band repeater on Sumbandila as listed below (all times in UTC; all activations 15 minutes duration). We appreciate all feedback, which you're welcome to post on AMSAT-BB, or alternatively on the Sumbandila Google Group (http://groups.google.com/group/sumbandila). For progress made during commissioning of the satellite, please see http://sumbandilamission.blogspot.com .

The CTCSS tone for the transponder is 233.6 Hz.

Uplink: 145.875MHz Downlink: 435.345MHz

Additional recommendations: Use only narrow FM Switch off compression Speak softly (mic gain down)

Satellite characteristics: All antennas are linear vertically polarized (1/4 wavelength) Sat Tx power = 5W Sat Rx sensitivity = -116.5dBm for 12dB SINAD Max antenna gain = 4dBi

Note that the satellite is currently in a controlled sun tracking mode with antennas Nadir pointing.

Apologies again for the late notification, but we're still in the commissioning phase and can therefore not guarantee the SA-AMSAT payload service far ahead in time.
