SSTV Transmissions From The ISS – December 8th & 9th

Slow-scan television (SSTV) transmissions from the International Space Station (ISS) are scheduled for December 8-9.  The SSTV images will be transmitted from RS0ISS on 145.800 MHz FM as part of the Moscow Aviation Institute MAI-75 Experiment, using the Kenwood TM-D710 transceiver in the ISS Service Module.

MAI-75 activities have been scheduled on December 8, 1235-1800 UTC, and December 9, 1240-1740 UTC.  These times correspond to passes over Moscow, Russia.  ISS transmissions on 145.800 MHz FM use 5-kHz deviation, and SSTV transmissions have used the PD120 and PD180 formats.

The ISS Fan Club website can show when the space station is within range of your station.  On Windows PCs, the free application MMSSTV can decode the signal.  On Apple iOS devices, use the SSTV app available through iTunes.

220 & 900 Repeaters Fully Functional

2016-10-09After many days and hours of work, the SEMARA 224.800 repeater is now back on the air and interfaced to a new repeater controller.  It has the ability to link via IRLP, EchoLink and RF through a remotely selectable 16-channel UHF radio.  It is mainly parked on the New England Network (IRLP 9120 / EchoLink 9129 *NEW-ENG*), in which the Quahog Repeater Network based in Rhode Island is also linked most of the time.

The SEMARA 927.8375 repeater’s IRLP node is now back up and running.  It is once again parked on New England Amateur Radio 900 MHz Network or “NEAR-900” (IRLP 9125).  The repeater controller for this repeater was left in place, due to the fact that using the IRLP node itself as a repeater controller isn’t reliable.  This means that all three SEMARA repeaters are now using their own SCOM 7330 repeater controllers and each repeater also has its own IRLP node.  Keep in mind that the fans in this repeater still need to be replaced, in which I need to get together with Jeff-N1ZZN to swap them out.

The 147.000 EchoIRLP node had apparently froze a few weeks ago.  Joey-KC1FWN had brought this to my attention last week.  The node was rebooted this morning and it successfully began working again.

Looking to the future, the 900 fan swapping and mounting of the 220 equipment in the 2m rack are the next tasks to tackle.  The equipment doesn’t look at all impressive right now sitting around at the repeater site unmounted.  I start a new job tomorrow and my time will be limited, however most of the heavy work has been finished.  Eventually, a dedicated 220 antenna will also need to be mounted at the top of our tower as I had previously mentioned.  The 220 repeater is temporarily using the 220 section of a tri-band antenna (a Comet CX-333) which is less than ideal.  I recommend that the club looks into buying a 4-dipole array antenna next year and plans a hardline/antenna install around the summer of 2017 through NETCOM’s maintenance window in our agreement with them.  At some point at a future meeting going into 2017, I will try to be present to talk about this and to make a motion to do so.

Thanks for your patience and enjoy your 2m, 220 and 900 SEMARA repeaters!

Tech Talk on Solar Energy – October 6th

2016-09-09Joe Tavares, KC1BGF writes:

I’ll be presenting a Tech Talk on Solar Energy following the 7 o’clock SEMARA Business Meeting on October 6, 2016.  Topics of discussion will include the following:

  • How solar panels work
  • Different types of panels; advantages and disadvantages
  • Power calculations
  • How to wire panels to batteries and load using charge controllers
  • The use of DC-DC converters to keep battery voltage constant
I will bring a solar panel and battery pack.

220 & 900 Repeater Update

2016-09-01Quick update before tonight’s business meeting:

The Raspberry Pi board for the 900 node which is used to link it into the 900 network was bad.  In the picture, the one in hand is the bad one with its replacement being tested behind it.  The board is $35, but I had this brand new one that I am donating to the club.  Also, the fans in the 900 repeater that cool the PAs have seized.  Via Jeff-N1ZZN, we will get replacements next week from another Motorola MSF5000, also at no cost to the club (thanks Jeff).

Planning to get the 900 repeater back on the air when I pick up the fans from Jeff.  The 220 repeater wiring is complete with a few level adjustments and programming of the repeater controller remaining.  I’d like to be able to make one trip to the repeater site and get both repeaters beck on air together when I get the fans from Jeff.

I hoped to have this all done in August as I previously stated.  Let’s aim for next week (again, please don’t hold me to it, but I will try).

Thanks for everyone’s patience during the downtime.
