Re: satpc32 doppler

I am using a prolific usb to serial port converter which uses a 64 bit driver. The other control program that I have tried for the rig is ARCS 2, but of course, doppler shift is not a function of this program, but it doed refresh the frequency display, both by the program, and manual turning of the rig knob. Thank you, kg2ix

Hi all, wouldn't it be fair to assign an OSCAR number to LituanicaSat-1? 73 Mike DK3WN

AO-7
by k4feg 02 May '14

02 May '14

The Eclipse Cycle has begun for satellite Ao-7. Typically what this means is that the satellite will lose all power and by default go into "Start-Up" mode every time it comes back into the sunlight. Typically Mode B or C are the 1st mode of operations and the loss of sunlight prevents mode switches to A. Predictions had shown that the eclipse would occur either yesterday or today, depending on the orbital model you used, and this morning over the USA, AO-7 was in mode B. I have calculated the end of the eclipse cycle but I will update satellite information to assure a more definite date for AO-7 to go back into full sunlight. /*This will be my only post on the AMSAT bb about AO-7, I will have updates on my Bulletin Board if you wish to follow them. See my QRZ.com page for information.*//* */ 73 Frank K4FEG EM55aj84ta

AO-7 in Mode B Today
by Paul Stoetzer 02 May '14

02 May '14

It looks like eclipse season has started for AO-7 as it was reported to still be in Mode B this morning over Europe and South America. This means it should be in Mode B daily for the next 16 weeks or so. Enjoy! 73, Paul, N8HM

Hi all, I want to introduce myself, My name is Björn Pasteuning, Callsign PD5DJ My QTH is Avenhorn JO22LO I'm active on the satellites from 2005, but just now entered the Amsat BB's I have made a lot a projects this last decade mostly relating to amateur satellites.. You can look for my projects on www.pd5dj.nl At the moment I am working on a fullsize portable satellite station. For that I made some Hardware and software to control the array. Hope to work you guys on the sats! 73's Bjorn de PD5DJ!

If I worked you, can you please send the info from our QSO? - my phone quit recording when the screen shut off so I have no clue... Sorry. I feel like such a lid :P Was a great pass though, lots of new calls and strong signals. 73, W0EA TJ ---- QRP ARCI #14612 | CW Ops #953 | SKCC #4593T NAQCC #3768 | Flying Pigs QRP #2254 http://W0EA.us *Because QRO is too easy (but sometimes required!)*

Re: Rotor control
by Richard Lawn 02 May '14

You might do a google search on easy rotor control. The company in Germany offers kits for as and el control of a large number of rotors out there that don't support rotor control out of the box. I recently built and install one on my yaesu HF AZ rotor and it works great! There website shows an extensive list of supported rotors and software. 73 Rick W2JAZ
