Yaesu G5400B rotator
by Robert Smith 23 Mar '14

Aloha My Yaesu G 5400B elevation rotor is seized, but the motors seem fine. Any suggestions on where to get it fixed and how much it'll cost. Yep, I realize Yaesu may be my primary option. Just looking for an array of options (if possible). 73 and Mahalo Respectfully, robert, NH7WN Honolulu

Es'HailSat-2 will carry two geostationary “Phase 4” amateur radio transponders !!
by Peter Guelzow 23 Mar '14

Es'HailSat-2 will carry two geostationary “Phase 4” amateur radio transponders !! As a result of a concept proposed by the Qatar Amateur Radio Society, Es’ Hailsat, the Qatar Satellite Company, have announced that their new, geostationary, Es'HailSat-2 communications spacecraft will provide transponders for use by radio amateurs. The spacecraft is expected to be ready for launch by the end of 2016. Es'HailSat-2 will provide a 250kHz linear transponder intended for conventional analogue operations in addition to another transponder which will have an 8MHz bandwidth. The latter transponder is intended for experimental digital modulation schemes and DVB amateur television. Precise uplink and downlink frequencies remain to be finalized but the uplinks will be in the 2.40-2.45GHz and the downlinks in the 10.450-10.500GHz amateur satellite service allocations Both transponders will have broad beam antennas to provide full coverage over about 1/3rd of the earth’s surface. Precise operational plans will be finalised over the coming months but it is anticipated that only quite simple ground equipment will be required to use this satellite. A team of amateurs, led by Peter Guelzow DB2OS (President of AMSAT-DL) are providing technical support to this ground breaking project which is expected to provide an exciting new phase of activity for radio amateurs for the 21st century. http://www.eshailsat.qa/ <http://www.facebook.com/l.php?u=http%3A%2F%2Fwww.eshailsat.qa%2F&h=AAQH7jWC…> https://twitter.com/eshailsat <https://www.facebook.com/l.php?u=https%3A%2F%2Ftwitter.com%2Feshailsat&h=2A…> https://www.facebook.com/amsat.deutschland

I agree with you Stefan. At 26 degrees east, the satellite should cover all of Europe and Africa. Coverage may stretch west to Iceland, eastern Greenland, and the eastern tip of Brazil. Coverage should stretch to the east to most of India, and western halves of China and Russia. It won't reach to North America, South America (except eastern edge of Brazil), Australia, or Japan. Nonetheless, it sounds like a great project, an excellent opportunity to gain experience with a GEO platform, and a demonstration of technical competence. Best wishes and hopes for success to the Qatar Amateur Radio Society and AMSAT-DL! 73, Steve N9IP -- Steve Belter, seb(a)wintek.com > > On Mar 23, 2014, at 8:00 AM, Stefan Wagener <wageners(a)gmail.com> wrote: > >> That is indeed a great project! >> >> Now, if the satellite is positioned at 26 degrees east it will not be >> useful for North America.

Hi John, I believe I am correct in stating that "SHIDAISAT " is correct and it operates on 437.525 Mhz +/- doppler. Regards Ken Eaton GW1FKY

I don't think it was in transponder mode for the pass over Hawaii at 2100z. The telemetry was strong but no response from the transponder 73, Tom, NH6Y

auto trackers for sale

I have and no longer use these auto tracking devices. Unitrac 2000 set up for a parallel port and a TS 2000. Endevour Auto tracker this will control the antennas but the tuning chip is not there (I think you can still get one?). $75 each and I will pay shipping. These items have not been used for 4-5 years, but they should still work OK. Perry WB8OTH py41(a)att.net sent from my Apple Macbook Pro
