Mac Doppler
by Joe 11 Jul '20

11 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)

AO-92 L Band Power
by Alan Blind 09 Jul '20

09 Jul '20

Using 10 Watts, I have not been able to get into AO-92 L Band. >From the AO-92 web site: ================ ......Since the 435 MHz uplink antenna is used to receive the 1267 MHz signals and may present a mismatch at that frequency, pre-launch estimates suggest that a power level of 100 watts ERP will be required for horizon-to-horizon access in Mode L/v. AMSAT Engineering will issue further guidance after in-orbit testing. Look for future articles on the AMSAT website and in The AMSAT Journal for equipment ideas and tutorials for accessing the L-band uplink. ==================== Perhaps my 10 Watts are too low. Have there been updates from AMSAT on recommended L band power? What power do others run? Alan WA9WUD

AO92 pass, 0510z 7/9
by Russ Kinner 09 Jul '20

I worked a station operating in Teton N.P. (DN43) on the pass Sat night and thought I had the call but even after listening to the recording I'm not sure. The call was in the fade when sent phonetically. Several other stations also worked him so if you heard KC5FLQ or KC5SLQ or his right call, can you advise? It's a new grid for me. Rusty, WA8ZID
