[amsat-bb] Re: Space Track Beta Web site

It looks like it has some nice features including only downloading only updates instead of all the data and a nice systematic way of downloading decay information (which is new I think). The one thing I am trying to figure out how it works is downloading updates when one has multiple clients. Is t

Wayne, I share your surprise that frequency information is not available in a machine readable format. As the cube sats are coming fast and furious, it makes keeping up with them harder. Charles On Jan 4, 2012 7:59 PM, "Wayne Estes" wrote: > I'm surprised that nobody has made an online reposito

I didn't think there were any vhf stations left. All the numbers on the channels now are virtual. All the tv antenna plans are for uhf bands. A quick look in the Boston market and the lowest channel is 19, channel 2@500MHz. Are there places that still use vhf? Charles On Dec 7, 2011 1:38 PM, "Bob

[amsat-bb] SRMVU Question

Hello, Operators seem to be tracking SRMVU as Object D (Which should be 37841 a.k.a. 11058D if I follow things correctly). However the TLE link for it at lists it as object B/37839/11058B. What is the current preferred guess as to which object is SRM

[amsat-bb] Re: Tracking program performance post chicken little date. (SatPC32 and GPredict)

Gents, Gpredict has simple formula based the tle for the decay date. That is starting to appear elsewhere for visualization purposes. The negative altitude is the result of running past where the data is valid. Charles On Oct 13, 2011 6:44 PM, wrote: > > Hi Tom. > > Interesting question. > > I

Mark, Gpredict should be blissfully unaware of the com port numbers. It talks to hamlib via TCP/IP. The com ports should live only in the hamlib world. Perhaps this weekend is time for a howto. My guess is it reads as follows. Install cygwin. Download, compile, and install hamlib. Test hamlib wi

Howdy, I do not recall predict having that capability. If they do, it would be great to see how they handle doppler of a moving qth. In gpredict we are adding gpsd support and would like the example. Charles AA1VS On Feb 18, 2011 12:47 PM, "Bobby Lacey" wrote: > Hi, > > Is it possible to dynamic

Howdy Jeff, Someone asked and here we go. A file attachment follows. Actually the diplexer looks pretty good. Less than half a db of loss at VHF and around half a dB at UHF. I checked the calibration and that was within tenth of a dB over the entire range. Any questions. Charles AA1VS On Sa
