SATpc32 -- Limit satellites to active ones?
by Thomas Schaefer 13 Apr '20

13 Apr '20

A related question…Is there some reason we need to carry old, no longer in-use, satellites in these files? This is not about the DOPPLER.SQL file but more about the lists in general as the elements files are full of objects one can never use for communications. For example, when I open the Satellite dialog, I see 200 available satellites. I have my filters setup but there is a big list of essentially no communication use—unless it comes back from the dead and the AMSAT News will tell me that I have no doubt. I was asking if one could filter the “Available” list but that looks to be just a representation of the files underneath (amateur.txt, cubesat.txt, etc). Just as we have editors for Doppler.SQL, I think one answer might be to create a new file with the active satellites in it (derived from the AMSAT satellites page). I can then use that my “Active sats” Keps file as my input. I can programmatically build the active sats file from the downloaded elements files. That seems like an easy Perl script I can put on a website. As far as a feature request (and this is purely for usability), I would summarize it thusly, add a feature where one can list the name of the satellites one wants to see in the Available file. This would be an Active filter. You can enable that with a checkbox to see active sats or all for historical reference. Then even though the program downloads the latest elements, it would only show the satellites in the active file or all if Active is not checked.

Good Contact???
by Brad Smith 13 Apr '20

13 Apr '20

<2 - A station calls me with My Call and Their Call.3 - I respond to them with Their Call & My Call/Grid> Since I am always operating handheld or portable, whether at my QTH, or roving, I cannot write the call down as it is being said, as both of my hands happen to be employed at the moment. Since a rover usually gives his grid, at least every few calls, I may say "Grid CM94, My Call" for example and the rover usually comes back at me and I appreciate that and I will then give my call and grid. Sometimes that is the best that can be done. I get his call when he comes back to me. I also record every pass on my iPhone. My memory isn't geed enough to remember 5 calls (or more, if I am roving) that I just worked, along with the activities of pointing an antenna and manually adjusting Doppler, so I rely on my recording. I know it is difficult to understand, but working portable is a lot different than sitting in front of an SDR computer screen in one's shack, with a 9700 with a speaker system and elevating and rotating, computer controlled yagi antennas. Some of us are doing this under not-so-ideal conditions. I have worked with my Arrow in the rain and in a snowstorm, several times without gloves, with noisy trucks going by and people asking me what I am doing,while trying to work. I have been asked if I am tracking animals and once as I was setting up, someone threatened to call the police. (I offered to let him use my phone, and I have Amateur Radio plates on my vehicles.) So, please cut some of us a little slack, if we are not operating exactly by "the book." Also, getting stepped on by the rude, big guns will eradicate part of the call. (Big guns are certainly more important than little portables.) If it is his/her call that gets stepped on, I can pick it up as he/she makes more contacts. If it is my call, I will email him/her to verify what my call is and make sure the contact is correct. Many times the person will thank me because he was missing one letter. Brad KC9UQR

what is a good contact?
by Ron VE8RT 13 Apr '20

13 Apr '20

maybe this has been brought up before, an alternative subject line might be "home far should you go" It seems that recording contacts and translating them into the log is acceptable. What about using post recording enhancements to pull call signs and grid squares out of the noise? A younger person with uncompromised hearing would do a better job at picking out contact information, the arguement might be made that even high end hearing aids do some audio processing. I just used Audacity to pull KJ7ATK's call out as Diawata-2 was low to my horizon, and his FM deviation was almost not there even though he had full quieting. I'll pass someone the recording if they'd like to hear it. Grid squares are required, is there an alternative other than RST? Ron VE8RT -- Ron VE8RT <ve8rt(a)yknwt.ca>

Yep, definitely more repeater stuff on the 15:20 pass this morning (early in the pass... it's cleared up now). No call signs heard this morning, but they were gabbing about corona virus on sea vessels. --Roy K3RLD

>From now on I'm just going to put my call out there on the satellite and ANY station that also puts their call out, will be considered a contact... (Tongue in cheek) I live in RI. If I try to work a station in AK or HI, I have to make sure I get their call AND grid correct, otherwise its a busted contact and a struggle to work them again. Using a recorder is good for logbook updates, but if I were to realize I got their call wrong, you bet I'm emailing them to set up a sked for a redo! It's the same thing for HF contacts... Im not here to argue, just answer a question. You're going to do what you're comfortable with. It's just a hobby - some people forget that. You didn't hear the call or grid right the first time? Work 'em again - it's moe funner that way! Larry N1MIW
