[amsat-bb] FQ56pm, Thule Greenland on the air today.
All, I am planning on leaving Thule Greenland on either Wednesday or Thursday of this week. I do not know how many more opportunities I will have to be on the air before I leave Greenland. We are not flying today so I will try to make the most of my down time and get on the air. I will try to be on the following passes today from FQ56pm: AO-51 1131UTC AO-51 1310UTC AO-51 1627UTC HO-68 1835UTC Thank you to everyone I've worked or who has tried to work me. You guys have made this trip a lot of fun for me. 73, Reid OX/N0RC ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

Sounds like one of the output transistors went bad (probably open). This would give you half power and higher input (IC821 to amp) swr.

[amsat-bb] Re: HO68 schedule needs looking at
The latest schedule (23 - 30 May) contains nothing but FM passes. Last weeks schedule contained but 2 (two) packet passes - of which only one was usable here in OZ. I take it that the omission of packet passes this week is deliberate and that the FM mode again can be used for packet as well. If that is not the case I respectfully submit that more packet passes be scheduled. One a day over Europe would be fine. Best 73 de Bent/OZ6BL Hostmaster for amsat.dk ___ Sent via amsat...@amsat.org.

How can you actually open a PL tone in ( Mode JA ) using an SSB transmitter ? In my opinion it is best to use a minimum EIRP power on FO-29 to conserve the battery because actually FO-29 along with HO-68 and OSCAR-7 is the best available satellite for linear CW and SSB operation. On FO-29 SSB I worked N2UN in New York from my JN70ES and it was a real thrill to contact Tony with his portable station on a promenade next to the East River. 73" de i8CVS Domenico ___ Sent via amsat...@amsat.org.

Hello, I'm Thu from Vietnam who is working in a cubesat project, too. Initially I also looked at Spectrolab and Emcore's solar cells but due to ITAR regulation it is very difficult for me to procure these cells so I have to turn to Azurspace (a Germany company). Their 3G28 cells are also triple junction with similar efficiency and the best thing I like is that they are ITAR-free, no minimum order (I ordered 20 units with ease) and nice email support. That's my experience so if you're interested to learn more, feel free to send me an email and I may help.

[amsat-bb] Re: Cubesat Group purchase of EMCOR cells
Hi everyone. I'm part of the Uruguaian group. This is the email that Emcore answered to me. EMCORE does offer mechanical/visual (MV) bare solar cells (MV cells are not available in SCA's). MV solar cells have mechanical anomalies or discoloration that make them unusable for space. MV solar cells have an efficiency typically greater than 25% at AM0 and 28°C. *Price * EMCORE offers MV cells for $50.00 (USD) each with a minimum order quantity of 150 cells. *Terms and Conditions* EMCORE’s MV cells are offered on an “as available, first come, first serve” basis. EMCORE’s standard terms and conditions for MV cells are as follows: 1. Parts sold on an “as is” basis with no warranty. All sales are final. 2. Quantities offered are subject to continued inventory availability. 3. Payment is required in advance of shipment by bank transfer or credit card. 4.Customer is responsible for all shipping costs (including insurance) from freight forwarding office. 5.Minimum purchase price is $7,500.00 for any order. Sorry for bother Warm regards from Uruguay Thank you very much.

[amsat-bb] Re: SatPC3 v 12.8a
Yes, it works fine, although I have not tried to steer the rotors or tune the radio with it under Windows 7 yet. One suggestion, though: during installation, do NOT accept the default installation directory. Install it into a custom folder in the root directory to avoid user account control issues.

[amsat-bb] Re: SatPC3 v 12.8a Windows 7 64 bit
I have used it with my FT-736R using the radio serial port using a Edgeport USB to 8-port serial converter and with USB port LVB tracker Yaesu G-5400 rotor control. All worked fine under Windows 7 64 bit Home Edition . I do seem to have an issue of RF interfering with the LVB tracker unit. Occasionally, the LVB tracker communications is lost when I am transmitting. If I disconnect the USB cable and reconnect it, LVB tracker works again. I have tested receive only operation for many hours and never had a problem with the rotor tracking or radio control. 73, Bill NJ1H On 5/24/2010 10:50 PM, Don wrote: > Has anyone used this software with Windows 7 64 bit ? > > If so does it work ok? > > > > WB8ZOM Don > > > > ___ > Sent via amsat...@amsat.org.
