Field Day
by Jack O'Mara 01 Jun '07

01 Jun '07

Hi Folks Its been about 2 years since I last ran our clubs field day satellite station. I use cw/ssb and it appears that AO 52 (hamsat) is the only one available on 2 M and 432. Please correct me if I'm wrong. Is there much activity on AO-52? I'm looking forward to working some of you. The call will be W4IY and we should be on all passes available to us in Fm18. Thanks for any corrections. Jack W4AD for W4IY

Satellites and Packet - Need a few pointers
by Steve Raas 01 Jun '07

01 Jun '07

In trying to maximize my satellite fun, I have realized that I have not tried the packet mode yet. So I set up my station for rx/tx on aprs. and using findu.com was able to establish that all is working as far as the equipment goes. I can send and receive packets fb. So the past few days ( very casually ) I have tried to receive some packets from the sats.. and I have not even been able to come up with a BLURP of anything so far ! Upon further investigation I read somewhere that the sats use SSB packet ? How is this possible with the Doppler and such? Or is it even true? Any info would be great. Ide love to add digital sat operations to the list of modes ! 73 N2JDQ Steven J.

AMSAT-UK Website Downtime

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greetings, This side of the building where our office is located along with the room that contains the AMSAT-UK webserver is being powered off sometime tomorrow (2nd June) for essential electrical maintenance. I dunno exactly when the power will go off and for how long, but I will be closing the AMSAT-UK webserver down late tonight in preparation for the poweroff. The system should (?) reboot automatically when power is restored.

Satellite Field Day
by Gary Mayfield 01 Jun '07

01 Jun '07

I hate being the guy to bring this up, but several guys pointed out tome at the club meeting tonight that on field day AO-51 will be runningas a "dual channel" FM satellite so the single contact Field Day rulewould not apply. I know this is not in the spirit of the rule - wouldit be possible to get a clarification out at this late of a date? Am I correct in assuming the spirit of the rule is to allow our clubone contact on mode J (V/U) and one contact on mode L (L/U) throughAO-51? While on the subject of Field Day rules *- if we were to work W1AW onSO-50 and then work W1AW on VO-52 (both are voice contacts). I believe this would count as 2 AMSAT Field Day voice QSOs, but onlyone ARRL Field Day QSO because "Satellite" is seen as a single "band" inthe ARRL rules, is this correct? Thanks and 73,Gary "Joe" Mayfield, kk0sdAmsat #21357 _________________________________________________________________ Add some color.

PCSAT-1 in Full Sun, Recovery Possible
by Robert Bruninga 31 May '07

31 May '07

PCSAT-1 is entering the full sun in the next day or so... PCSAT-1 is fully recoverable *if* we can just find the right time (and place) to send the commands. For the past 6 years, we have always been able to fully recover PCSAT-1 during a full sun period (during the Fall, Winter and Spring) because of favorable sun angles on the -Z face. We have never been successful during the Summer full sun periods because the sun is in the Northern Hemisphere and our best solar panel points the other way. In fact, monitoring 145.825 we hear nothing from PCSAT-1 (W3ADO-1) (in the Northeren Hemisphere). HOWEVER, I just realized that we have never really made an all-out effort to try to revive PCSAT-1 in the Southern Hemisphere, or mid latitudes during the Summer. Where we commmand from can make all the difference since each latitude sees PCSAT-1 at a different orientation during this full sun period. We need to find the right one to get the 2 commands in for a full recovery. So, we are looking for stations not in the mid Northern Latitudes to *monitor* 145.825 MHz for packets from W3ADO-1 in other parts of the world. If you get any packets, let us know. You might be in the right place. The http://pcsat.aprs.org shows that none of the existing ground stations are hearing W3ADO-1 right now. But then most of our ground stations are in the Northern Hemisphere. We only get one week to recover PCSAT-1. But if we recover it, it usually last for a month. All potential recovery passes are in the mid morning in the Southern Hemisphere. Anyway, just something else to do if you have time... Bob, WB4APR US Naval Academy Satellite Lab
