ISS over West Malaysia
by 9w2qc＠9w2qc.net 13 Sep '07

13 Sep '07

Dear All, Greetings from Kuala Lumpur, Malaysia. I would like to inform that this afternoon, at 1429 hours local or 0629 hours UTC, we had a 31 degree pass of ISS over Kuala Lumpur. During this pass, we managed to copy ISS on 145.825 MHz with very strong signals from AOS to LOS. Also heard E20YJC's APRS beacon and saw him accessing the BBS (RS0ISS-11). Its nice to see ISS active again. 73, Sion Chow Q. C. and Sangat Singh, 9W2QC and 9M2SS Operating 9M2RPN. -------------------------------------------------------------------- myhosting.com - Premium Microsoft® Windows® and Linux web and application hosting - http://link.myhosting.com/myhosting

BB Anyone on the BB having success in the current mode. I have not been able to copy any D/L activity on S-Band. Maybe my new Keps S/U downconverter is not working. 73 Bruce KG4YEV

I had two QSO's on AO-51 mode L/S this morning on the 1310 UTC pass. I normally use a 1.2 meter dish for the mode S downlink antenna with a DEM downconverter. On this pass I tested a 52 turn helix with an AIDC-3731 downconverter. Receiver performance was very good with consistent S7 to S9 signal strength and full quieting of the FT-736R for all of the pass except at low elevations at AOS and LOS. This performance tends to confirm my direct comparison measurements and dissagrees with statements made in ARRL publications and expressed elswhere that the gain of helix antennas flattens out above about 20 turns.

radio equipment
by Mike Nettles 12 Sep '07

Hello to the list. I have a chance to put a satellite station in our new state eoc. I have to get a list of equipment together so it can be sent out for bids. My question is what radio currently available can do 38.4k speed digital right out of the box or with simple mods? Also what selection of 2m, 70cm and 1.2ghz antennas and pre-amps would give us the best performance for the sats up now and the sats that are planned? Thanks Mike kb5wbh Ar State RACES Officer

Need Oscar-7 help!
by John Marranca, Jr 12 Sep '07

12 Sep '07

Hello all. Well after a nearly 90 degree overhead pass tonight, I failed once again to make it into the Mode A translator. The signals were great on the rx side. On the tx side, I inserted the radials into my 144 Eggbeater to concentrate more signal overhead. No dice. However, I must add that my "everything" rig that I am using for...well...everything ham related is a Yaesu FT-817ND. Do I simply not have enough transmit power into the bird? Any info is appreciated. John KB2HSH --

contacts in mainland china /advice wanted
by andy thomas 12 Sep '07

12 Sep '07

Hi there's a strong possibility that I may be going to China (Beijing & possibly Xiamen in Fujian province) in late October/ early November. I was wondering if anyone has any info/contacts there in the amateur satellite community??? I doubt if there's time to get a licence to operate /P on the satellites but it would be cool to make contact over there anyhow. Also if anyone has any advice about duty free or market purchases of radios or Taikonaut memorabilia (sorry OT) please also contact me. I'm at andythomasmail AT yahoo.co.uk (reformat and use @ as appropriate) all help and guidance gratefully received. 73 es gud dx andy thomas G0SFJ ___________________________________________________________ Yahoo!

Home brewing El. Az. rotators
by Tony VK5ZAI 12 Sep '07

12 Sep '07

Hi Guys, Seems a lot of talk about rotators lately, have you thought about building up your own, I did this around 15 years ago and the system has never been switched off apart from twice when moving QTH and the occasional service, greasing etc. My present QTH is 300 yds from the Southern Ocean and we get some almighty winds in the winter but it keeps on going. It's driven by 2 windshield wiper motors and constructed of parts that can generally be scrounged from vehicle and machinery junk yards etc. You will require a small welder to put it together and access to a lathe but really there's no great precision required in it's construction. I've described it's construction on my web site listed below. hopefully it will be of interest to some of you. -- Regards Tony.
