by GRAHAM SHIRVILLE 14 Feb '17

14 Feb '17

The launch time for the Nayif-1 CubeSat remains as03:58UTC on February 15th 2017 on the PSLV C37 vehicle. We expect the launch to be webstreamed at http://webcast.gov.in/live/ A set of pre-launch TLEs have been released:NAYIF1 17002U17002A 17046.17824931 0.00000000 00000-0 00000-0 0 9993217002 97.5521 107.5843 0004848 278.6481296.8511 15.21991390 01 This filecan also been downloaded from here http://download.funcube.org.uk/nayif_tle.txt We now expectthat the FUNcube transmitter on Nayif-1 will activate at approximately 04:47 UTCFeb 15th. (NB – This is a revised AOS and it is still Tuesdayevening in America!) Initial transmissions will be in “safe” mode andwill be of the 1k2 BPSK telemetry only with approx 50mW of RF power on145.940MHz. Atthis time the spacecraft will still be over the Southern Pacific Ocean but AOSin Mexico is expected at around 04:54 UTC and the first pass will then tracknorthwards in range of stations situated in the western US and Canada. During theLaunch and Early Operation phase (LEOP) of the mission, the Nayif-1 command team will be headquartered atthe American University of Sharjah Ground station in the United Arab Emirates. Theywill obviously be especially keen to have all possible reports of signalreception during this first orbit! To encourage everyone to take part, therewill be a small prize for the stations that submit the first data to theNayif-1 Data Warehouse. Please help the team if you can. Details ofthe Nayif-1 frequencies, together with details of how to the download the Dashboardcan be found herehttps://funcube.org.uk/2017/02/08/nayif-1-launch-date-now-confirmed/ The Data Warehouse is still under final development butcan be viewed here: http://data.amsat-uk.org/nayif1/index Please note that if you are already a registered user ofthe FUNcube Dashboard then you do not need to re-register. Your existingdetails will transfer automatically to the new Dashboard when you run it forthe first time. If you run the test file with the Nayif-1 Dashboardplease do not expect the Warehouse to show the data - it is from an earlierdate than that is already displayed. However the “packets uploaded” tab at thebottom right corner of your Dashboard will show that the files have uploaded OK,that all is well with your system and that it is ready for action. The AMSAT-UK and -NL team will also be using the #funcubeIRC channel on launch day and you will be very welcome to join them there. Ifyou do not have the Dashboard available then also please submit your heardreports via IRC as well. A web client can be found at http://irc.lc/freenode/funcube if youdo not have an IRC client installed. 73s from the FUNcube team

Re: [amsat-bb] Grid Activations 2/12-3/4

Hi Sean, I'm getting a lot of requests for various Grids down herewhile snowbirding - HIHI. My plan is to mesh the passinfo with the Family skeds and publish a plan. I'll be hereuntil 3/4, so there will be plenty of opportunities. Therewill be a couple days notice each time. 73, Bob K8BL/5 (EM20vg) (Near EL29, 39,EM20/21/30/31) From: Sean K. <kx9x(a)yahoo.com> To: R.T.Liddy <k8bl(a)ameritech.net> Sent: Sunday, February 12, 2017 8:03 PM Subject: Re: [Starcom-bb] Grid Activations 2/12-3/4 Hi Bob- I need all grids in that area except EL30 and EL40. Will look for you on daylight passes of SO50 and FO29. Thanks for your efforts!

Not willing to give up Ham Radio during that time, I bring my SAT gear with me and activate nearby Grids. The activations would all be during daylight hours and probably just on FO29 & SO50. I get very nervous doing things at night that people don't understand! If you want to schedule something between now and 3/4, let me know. 73, Bob K8BL/5 P.S. See my QRZ.com page for QSL info.

Phasing lines for 2-m Yagi circular polarized project
by Dave Mann 13 Feb '17

13 Feb '17

I have prepared my 2-m yagis. Now ready to set them up to use on the birds. I'm thinking setting one horizontally and the other vertically, spaced about 1 ft apart on a boom. Now, how to measure the coax and connect them for circular polarization? FYI, when all set up, I'll put the project details on my Dropbox with a link. Request ideas, guidance, advice, comments, please. 73 Dave N4CVX Sent from my iPad

Grid Activations 2/12-3/4
by R.T.Liddy 12 Feb '17

12 Feb '17

February is when the XYL and I do the snowbird thing from Ohio and stay with our Daughter's Family in SE Texas. Not willing to give up Ham Radio during that time, I bring my SAT gear with me and activate nearby Grids. Yesterday, I checked out my equipment/antenna from the driveway and worked 7 stations from EM20vg, including UT1FG on FO29. Today, I went to EL39 and worked 18 stations on SO50 & FO29. This location makes it easy to activate several nearby Grids since it is almost in the corner. EL39, EL29 and EM30 are all a short drive. I have a good spot mapped-out for EM30/31 line, too. The activations would all be during daylight hours and probably just on FO29 & SO50. I get very nervous doing things at night that people don't understand! If you want to schedule something between now and 3/4, let me know. 73, Bob K8BL/5 P.S. See my QRZ.com page for QSL info.

Just recently the big blue circle showing the satellites footprint will not move for several minutes.the program still controls the radio for doppler shift and rotors are controlled perfectly.Just the footprint hangs up.OPTIONS show the map should update every 10 seconds. It has always worked perfectly until late. What's my problem ?thanks to all who reply !Jeff WB8RJY jeff broughton
