[amsat-bb] Re: satpc ?
Bob, This, from the web site, looks like your problem. You can get the patch or latest version there. Alan WA4SCA 5. Patches a. SatPC32/Wisat32 patch The ZIP file that can be downloaded with the link below contains revised SatPC32.Exe and Wisat32.Exe files (English demo version for North American users). The files that come with the 12.8a setup file cause a math error (message: Ungueltige Gleitkommaoperation = Invalid floating point operation) in the following case: a. In menu Optons the SGP8SDP8 model has been chosen (the SGP4SDP4 model works flawlessly). b. An element in the Keplerian data set (bstar drag term, data line #1, col. 54 - 60) contains the value 0. Presently (Dec. 2009) that is the case with data sets for HO-68. Selecting the SGP4SDP4 model fixes the problem also. The results of both models are of equal precision. Further, the revised SatPC32.Exe file fixes the following error: When the program's Priority function automatically switchs to a satellite it will set a possible converter or transverter offset to 0. So, the radio will not be tuned to the required downlink or uplink frequency. ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: My $0.02 worth
Ditto on Larry's comments. Coming off my KH6 Dxpedition in March/April, I can concur there are not enough users on the current linear satellites. Out of the 50 passes that I worked, mostly on SSB. I only made 50 contacts! On about 3/4 of the passes, I had the satellite all to myself! This included FO29, VO52, AO7 and HO68! One day, I had one pass that was deep into CONUS on HO68. I had previously announced my intent on the AMSAT BB to be on the pass. During the entire pass over CONUS I did not work one single station. I eventually heard one of the KH6 stations on Oahu pop-up to say hi as he felt bad that I could not work a single station during the entire pass. Go figure! The same happened on several passes over Japan. I was asked to make an effort to work JA's as KH6 is difficult and rare for them. Again I announced the passes I would be on. I tried eight different passes often calling and calling. I eventually made contact with two stations one stormy evening. I was later told the passes I was on were usually at 4PM in the afternoon when most stations are at work. Let's use the resources we have. We have four great LEO's: FO29, VO52 and HO68; and AO7 when she behaves. Let's get more activity going on these satellites. I know there are many operators with single SSB Multimode rigs. Half duplex does work with SatPC, see my DXpedition article on the Caymans last year. I have already had several email on how to do this from interested operators. We should encourage newer operators to take the plunge even with just one radio, with some assistance from the AMSAT community to get it right. Let's get on the air! My 2 cents. 73, Adrian AA5UK From: Larry Gerhardstein w...@montana.com To: amsat-bb@amsat.org Sent: Thu, June 17, 2010 8:58:04 PM Subject: [amsat-bb] My $0.02 worth I don't feel a bit sorry for those who gripe on this BB about there not being enough HEO birds, too many FM birds (operators), not enough linear transponders, or the like. Yesterday, I encountered a nice FO-29 pass with maxEL about 60 degrees here at my QTH. I heard no one, yet I could hear my CW/SSB downlink signal from the bird loud and clear. For awhile the footprint covered the entire 48 state region. I thus called CQ for nearly 15 minutes, but no one (that's zero, na-da) came back to my calls. Then later there was a good VO-52 pass and I did manage to work N6PAA, very good clear SSB signals both ways. But during the 10-15 minutes of that pass, I heard no one else in a QSO or calling CQ etc. I think before we start making complaints about the current state of affairs, we seriously consider making use of those resources we do have at present. And then make a financial donation to the various AMSAT's and teams working to make future birds possible. We all want another HEO with lots of modes/bands, but complaining will not make one magically appear. 73, Larry W7IN, DN27, Plains Montana. ___ Sent via amsat...@amsat.org.

[amsat-bb] HO-68 question
Sometimes when HO68 is not advertised by Alan to be ON, I can hear myself on the down-link frequency. Why is that. Is the sat really ON, or am I hearing intermod in my own equipment? BTW, this was during a near overhead pass. Tnx, Larry W7IN ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] Re: HO-68 question
I've noticed this a few times as well and it has not been intermod as I've had QSOs. For a while I had hoped that the bird was going to be turned on and left on but that has not been the case.
