Can't Control IC-910 Using Gpredict/Hamlib On Raspberry Pi
by Roy Dean 10 Jul '20

10 Jul '20

Bernhard, Have you tried the GPredict Forum? Thats where I learned about the 910/9700 patch (but I don't own either so don't have experience). I think the patch author or Alex Csete would be happy to describe the process. https://community.libre.space/c/gpredict/17 --Roy K3RLD

Re: [amsat-bb] The Explanition Has Come
by Daniel Schultz 10 Jul '20

10 Jul '20

We have recently discussed in this forum the reasons why there are no more ham radio satellites in HEO. We have reviewed the various external factors such as a saturated and highly commercial secondary launch market, new government regulations that did not exist 25 years ago, commercial and government interests that might simply prefer that amateur radio and amateur satellites "go away" in order to make life easier for them, and other factors all external to AMSAT. What we did not consider was the possibility of internal squabbles threatening the organization. I have seen more than one organization fall apart because of such in-fighting. Please be aware that this internal threat can be deadlier than any of the external factors that are preventing us from launching new satellites. I don't know which side is right. Perhaps both sides, perhaps neither side. I just know that it would be a god-awful shame if AMSAT's remarkable 50 year adventure should come to an end because of this. It is time to sit down like ladies and gentlemen and calmly discuss these various differences without bringing the legal profession into the equation. Perhaps the board candidates could make calm and rational statements to the membership on how they plan to accomplish this, so that the members can make rational choices in the upcoming election. If this cannot be done then we should probably all just sell our radio gear and find some other hobby that we can pursue on our own without the need to form or govern any organization. 73, Dan Schultz N8FGV

I will second Rick's request. The past actions against the new board members showed the poorest leadership that I have ever seen. The ethics of this action eroded away any confidence that I had in this board. 73 Brad KC9UQR

Mac Doppler
by Joe 10 Jul '20

10 Jul '20

A buddy of mine just installed MacDoppler It seems to work great but he sent me a video that doesn't make sense to me. It is controlling his radio changing freqs as needed to account for Doppler. BUT... I have never seen this before. the 144 band was changing one way in freq and the 440 band the other way. Huh? That doesn't seem right in my head. anyone care to maybe explain whats happening?

Can't Control IC-910 Using Gpredict/Hamlib On Raspberry Pi
by B J 10 Jul '20

10 Jul '20

I recently installed Gpredict and Hamlib on my Raspberry Pi which runs Raspbian. I'm unable to control my IC-910 because of a known bug. I'd like to rebuild them from source code and I've located a patch. The thing is that the patch is a directory, not a single file. I don't normally work with Linux and I have no idea how to apply that patch directory to the original code. Does anyone know how to go about it? I could try the brute-force method by physically adding or exchanging the patch files, but I don't think that's a good idea. I've found some information on doing something like that using the commands "diff" and "patch" but, when I tried those methods, I must have done something wrong as I get some rather cryptic responses. Any ideas or suggestions would be appreciated. 73s Bernhard VA6BMJ @ DO33FL

Greg, Thanks for the valuable email. your info has been added to my 5500 manual. My question is, if they're still manufacturing the 5500, where's the switches coming from? Do they have stock for manufacturing but unavailable for spare parts? Thanks Mike (K9QHO)
