Does anyone have a diameter setting for ISS that gives a decent approximation of visual magnitude (Magn in Instantrack)? Thanks, Rich, N8UX

HI satellite contact
by Wyatt Dirks 18 Jun '11

18 Jun '11

I have been working toward getting worked all states over the satellites. Well i am down to only two states HI and AK. I am working with several people in AK to get that state on the worked list. Now i need some help with HI. Is anyone in HI on any of the satellites? I am in Iowa so it will probably have to be over FO-29 or AO-7. If anyone can Help me with this i would greatly appreciate it.

Keps
by CT2IWW Paulo Teixeira 17 Jun '11

17 Jun '11

Hello everyone, Is there a program or script that could automate the creation of a custom keplerian element list that includes satelites that i´m only interested in, from data from either either spacetrack or celestrack? My idea is to create something similar to the list that AMSAT publishes but more specific to my needs, meaning that there are some sats in there that I don´t care about. I tried the TLEretriever but no cigar there, at least for the purpose in sight. 73´s Paulo CT2IWW

ISS orbit raised, again
by Alan P. Biddle 17 Jun '11

17 Jun '11

According to Roscosmos, they have raised the orbit again by 6.8 km. They are up to about 382 km. This boost will cause old Keps to lag about 130 seconds per day, so be certain an use the CelesTrak/SpaceTrack Keps, or the predicted Keps. http://www.federalspace.ru/main.php?id=2&nid=11912&lang=en 73s, Alan WA4SCA ----------------------------------- Who is John Galt?

The SO-67 command station has agreed to set the following start times for 15 minute activations over North America for Field Day. Activations are -planned-, and are dependent on scheduling and battery state. Remember both ARRL and AMSAT Field Day rules limit QSOs to one per FM repeater/satellite. Even if you are not submitting a log, please adhere to this procedure. 25JUN2011 1835 2255 26JUN2011 0030 0200 0335 0515 0645 1155 1335 1510 1640 1815 Uplink is 145.875, no tone, and Narrow FM if possible.

Better work that HF DX while you can!
by Jeremy Bomkamp 17 Jun '11

17 Jun '11

If this is true, the last thing I am worried about is DX, I saw a tv show that talked about the mini ice age in the 1800's and they mentioned the cause was a lack of solar activity. Time to be cutting a lot of wood and buying more blankets if this is going to go on for 2 decades. The show had to be on Discovery or History channel. I haven't googled this(yet), but there has to be a trend and when did the decline start(sunspots)?

I use these programs to customize a list of satellites with their current tracking data. Nova for Windows has a feature to customize a list of multiple satellites _http://www.nlsa.com/docs/nfwquick.pdf_ (http://www.nlsa.com/docs/nfwquick.pdf) and watch each satellite footprint as they travel across a rectangular map _http://www.nlsa.com/nfw_maps.html#Rect_ (http://www.nlsa.com/nfw_maps.html#Rect) I also use SATPC32 which has pretty much the same feature set. _http://www.dk1tb.de/indexeng.htm_ (http://www.dk1tb.de/indexeng.htm)
