I'm trying to figure out who, if anyone, activated FQ56 (Thule) before me. Does anyone know, or know of past Greenlandic operators? 73, Reid N0RC

AO-7 Mode C? (Or other reason for varying signal strength?)
by Bill Dzurilla 04 Apr '10

04 Apr '10

Hi folks, Since starting my effort to work Europe on AO-7, I've found that the very low elevation sigs vary significantly on different passes. Some mornings I can easily hear my downlink and start working Europe at 0.7 degrees elevation, while other days I can't hear myself until 5 degrees elevation, after the window to Europe has closed. Not sure if this is due to band conditions, satellite polarization, obstructions at certain positions, operator error, local noise, or what. Today I spoke with another experienced AO-7 op and he had an interesting theory: on the bad days (when I don't hear my downlink until 5 degress), the sat is in Mode C (lower power). This seems to make sense, because there does not seem to be any middle ground -- I start hearing my downlink at either 0.7 degrees or 5 degrees, never at 2-4 degrees. Anyone have any thoughts on this? Are we able to predict when the sat will be in one mode or another? Or any other explanation for the signal strength variations? 73, Bill NZ5N

AA5UK/KH6 BL02ic schedule for April 5th
by Adrian Engele 04 Apr '10

04 Apr '10

All my time in Kauai is rapidly coming to end. Here are the last passes I will to to get on today: April 5: AO-51 02:05 UTC VO-52 06:28 UTC FO-29 06:53 UTC. I am sorry I cannot make the FO-29 passes at 03:26 and 05:07. I will be out for the evening for a last dinner. Thanks again for the great contacts and effort to work me under difficult wind, rain and static noise conditions. Tomorrow I will be heading back to Oahu for a couple of days. More than likely I will not be operating as there are mountains to the North and many hotels blocking possible the path to the satellites. Aloha from Kauai. 73, Adrian AA5UK/KH6

James, KK6MC and Ron, W6QZ have both mentioned John Browning, W6SP (SK) as working satellites from Thule. Does anyone have more information on his operation from here?

AO-51 mode change
by Mark L. Hammond 04 Apr '10

04 Apr '10

Hi All, AO-51 was changed a bit early today, at 21:10 UTC 4 April. It is currently in "normal mode", with 435.300 (145.920 uplink) running about 480 mW (and 435.150 running about the same). We hope to catch up on some telemetry during this week. If we don't need any telemetry, it is likely that we'll increase the power on 435.300. The schedule for the rest of the month should be posted soon--sorry for the delay. Beginning with May 2nd, periods of eclipse return to AO-51. We'll have to watch the satellite carefully and make some modifications to what we've been doing over the last several months. More details as we get closer to the eclipses... 73, Mark L. Hammond [N8MH]

AO-07 pass
by Dads 04 Apr '10

04 Apr '10

I was on this last pass on AO--07 at 15;40 Z. I tried to call CQ no answer. I heard k8yse with a good down link, I gave him a call but no answer. I had a good downlink too. Do some people have receive problems ?? 73 Jerry w0sat

Low AO27 Hawaii footprint
by Robert Smith 04 Apr '10

04 Apr '10

Aloha all... I will take about a 30 minute trip at noon. >From 22:23:28 thru 22:27:28 there is a low pass (1 deg) "over" Hawaii extending to the western boundary of those states bordoring the Mississippi to the west. 51 workeked well at this elev. a month ago. 27 may be rought but I will give it a try if anyone is interested in the attempt. Happy Easter to everyone. And of course, 73. respectfully, robert NH7WN Honolulu

SATPC32-FT-736R Interfaces?
by Allen Vinegar 04 Apr '10

04 Apr '10

OK, it looks like something may have gone bad with my interface. What CAT interfaces are people using with an FT-736R and SATPC32 on their computers and are happy with? Many thanks! Al W8KHP
