AO-7 Status: June 4, 2014
As of May 2, 2014, AO-7 has been in what I refer to as the "Eclipse Cycle", this means that at least once a day during the satellite orbital path over the Southern Hemisphere, the satellite goes into complete Solar Eclipse or Umbra. As a result of the batteries in AO-7 being completely dead and now "OPEN" the Sun is the only power source for operations and the loss of all power during the Eclipe or Umbra will result in AO-7 coming back on in the 1st state of operations each day.
Based on published information and my personal conversation with Jan King, builder of AO-7, the 1st state of operation is typically Mode B. During the last 2 weeks of the "Eclipse Cycle" there have been reports of AO-7 shutting off during the pass over the Northern Hemisphere while in full sunlight. I have my 10m antenna down at this time and I am unable to check to see if there is a Mode Switch that has taken place. I am trying to collect observations about how AO-7 acts during these periods of Total Solar Eclipse and attempt to determine if there are any significant events that occur during this period of satellite operations.
I would be most interested in anyone's observations of AO-7 and it's operations during this time, I will attempt to update here, any significant events that are observed during The Eclipse Cycle of 2014, my current estimates of the end date is approximately August 21st or 22nd of this year, a period of 16weeks.
Star-COM.net BB and it's new "Sister Site" SatDX-BB are up and running.
SatDX-BB will concentrate on making a BB platform available for International Operators on the satellites who wish to pursue "DX" on the satellites. I invite all international operator's who have the "AOS/LOS" capable stations to check out SatDX-BB, we are just getting it up and running and my European Admin is in place to help work with the European Satellite Community. The sign up page for either StarCom-bb or SATDX-bb is as follows:
from this page you can sign up for either of the bulletin boards
QTH: EM55aj84tahttp://no.nonsense.ee/qthmap/This web page will accept the 10 character Alpha/Numeric identifiers of the Maidenhead Grid Square System for the highest degree of accuracy you can achieve when calculating distances between stations.
Welcome Satellite Lovers!
I have created a Satellite Users Bulletin Board
These BB's will cater to actual satellite users, it is a moderated board with initial posting privileges having to be approved by the ADMIN(ME!) after that post away. This will be an email style BB. The site should let you sign up and unsubscribe if you find you do not like the content of the BB.
is the sign up page.
This is the product of the Grid Guerrilla newsletter I created for Grid Hunters on the satellites, I hope to expand this to encompass other VHF/UHF operations as well.
I hope to expand the STAR-COM.NET primary site soon, come join us on the "Birds"!
Recently I added a SKYPE account to my tools to work the wonderful world of satellites. My account name is:
My satellite operations in working with European and South American stations has been helped tremendously with the use of the "Frequency at the Satellite" feature that Erich, DK1TB, has incorporated into SatPC32 v12.8c.
That feature allows both operators to select a frequency in advance, and then when the satellite is over both stations they can attempt a contact without having to search for each other. Erich and I back during the winter, using this feature were able to hear each other during a 40 second opening on FO-29, Erich and I are 7,533.685Km apart, which is a significant distance for FO-29, after just 3 attempts we were able complete a QSO on FO-29. Satellite DX is a challenging part of our hobby and great distances can be achieved with some planning & hard work.

After a 20 year hiatus from the hobby I have returned. My current passion is working the satellites, I work the satellites daily.
Currently I am working AO-7 Mode A & B, VO52, SO50 & FO29.
If signals are weak into the "bird" I will drop down below center frequency and operate CW, (I am the one sending between 10-18 WPM!)
I am retired and if anyone anywhere wants to try a satellite contact, drop me an email and we will make a schedule.
I do like to "chase" new grid squares so I try towork as many of the "new-comers" as I can, you never know where they might be and we were all new at this at one time or another.
I have been in this HOBBY since 1976 so lets all remember we all were a "new-comers" at some point in our radio careers. I do not care if you have a code or no code license, I am an "old-timer", that and a couple of bucks will get me good cup of coffee from Starbucks!
If I can help you out just ask, If I need some help, I am for sure gonna ask.
For the "New-comers", WELCOME TO THE HOBBY! for the "Old-timers" LET'S ENJOY OUR HOBBY"
Thanks for looking me up on QRZ!
I know my grid doesn't always fall into a footprint that will allow me access to Europe, but I am in the foot-print at low angles if anyone would like to give it a try, time of day is not an issue with me.
My mobile set up is becoming more of a "Portable" set-up, I have an Icom IC-910h that will be my new mobile/portable rig, I will use simple antennas when mobile, I have both an Elk and an Arrow for the "fast and dirty" operations and for serious portable operations I am building a small antenna system using two shorter versions of my base station antennas, mounted on a Glen Martin roof top tower on a small trailer.
It's good to be back on the AIR!
