AO-16 Update and brief mode change
by Mark L. Hammond 02 Sep '08

02 Sep '08

Hello All, AO-16 has been in its "voice mode" continuously for nearly a month now. Many thanks to all the users of this "new" bird! It is time to pause voice operations long to receive some MBL telemetry (limited as it is, it's all we have). Around 0920 UTC on 17FEB08 I plan to return AO-16 to digital mode in order to receive some telemetry. If all goes as planned, it should be back to "voice mode" during the same pass. If not, I'll try to catch it on the 1056 UTC pass. Most of you will be asleep, so I don't think it will interfere with too many contacts. Looking to the future, we can see that after several months of continuous illumination, AO-16 will begin to experience eclipse periods at the end of March. The eclipse periods will increase and extend through the summer. This may impact AO-16's power budget such that the transmitter output will have to be reduced in order to protect its 18 year old batteries. We'll know more after the eclipse periods begin in late March and early April. In the meanwhile, enjoy AO-16 and her strong signals! 73 on behalf of the command team, Mark L. Hammond [N8MH]

31 Jul '08

Hi, I own an Icom 910H and would like to add a pre-amp for 70cm any recommendations? The AG-35 is a possibility, I like the connectivity with the rig, however I can't find any N.V info on the unit. Advanced receiver had some nice units, any ideas would be terrific, thank you. 73 Pete WB2OQQ

Vanishing PCSAT?
by Robert Bruninga 31 Jul '08

31 Jul '08

> I've probably missed the "answer" on AMSAT > but where is PCSAT? Good question! I was going to send you the standard response saying she is napping in the dark, but just did a quick check myself and PCSAT (W3ADO-1) has not been heard since 2 July at 11:52:39 and the last station to digipeat through it was SP9UX on the 5th at 04:09:14 and the last USA station was W4AEJ on the 1st at 14:04:28... But I also notice that PCSAT passes are at night over the Northern Hemisphere where everyone lives. Maybe we can wake up someone down-under to see if they can listen for PCSAT (W3ADO-1) NO-44 on 145.825 MHz... May not decode it, but should be able to hear it attempting to send a packet once a minute.. Only in the sun, of course... So Robert, thanks for bringinig this to our attention... PCSAT was launched on 30 Sept 2001. Bob, Wb4APR
