2008 ARRL SW Division convention (12-14 September)
by Patrick STODDARD (WD9EWK/VA7EWK) 12 Sep '08

12 Sep '08

Hi! I will be part of the AMSAT table at the 2008 ARRL Southwestern Division convention in Mesa, Arizona, over the next 3 days (Friday 12th through Sunday 14th). There will be satellite-related presentations at the convention, and on-air demonstrations. I plan on trying to work many passes on the FM satellites (AO-51, AO-27, SO-50) and also FO-29 and VO-52 from outside the convention. For more information about the convention, please see: http://www.azhamcom.org/ Stations making contacts with WD9EWK during the demonstrations at the convention will receive a QSL card. The convention is in grid DM43ck. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Grid CO-45

Hello Folks, Randy, WI7P was just on AO-27 from Ketchikan, AK CO-45. About 2245Z Thursday. Maybe he'll show up on AO-51 tonight? If you need it, keep an ear peeled! 73 John K6YK ____________________________________________________________ Click here for free information on earning a criminal justice degree today. http://thirdpartyoffers.juno.com/TGL2141/fc/Ioyw6i3nNLMpfSCElIHEw8t8Iqtc7IN…

AO51 mode: 23cm SSB up / 70cm FM down ?
by Henk, PA3GUO 11 Sep '08

11 Sep '08

Dear all, I was considering to submit the following mode to the AO51 command team. (I did this already a while ago but my emails seems to bounce) Objective: provide a means for stations with small ERP to test their 23cm uplink channel into AO51. Uplink 23cm SSB (!) Downlink 70cm FM (preferably 435.300) With 23cm FM uplink I seem not to have enough ERP to get over the sat. That is, I never made it through the squelch level of the AO51 receiver (using Kenwood TS2000X/10W, and a small cubicle quad antenna only). In SSB mode with the squelch open I could try even CW to see how weak my uplink is. Maybe just below squelch level, maybe far down in the noise. And: with SSB we can even have multiple stations testing their links at the same time ! Any thoughts of anyone else before I submit this request ?

Hi all, COMPASS-1 is back in NORMAL mode. At 21:44 UTC I could command successfully the satellite. Today the battery voltage seems locked at 4.0 volts.

AIDC 3731 problem?
by Doug Kuitula 09 Sep '08

09 Sep '08

Hi all, I've been trying to receive the 2.4 ghz from AO-51 using an AIDC-3731 downconverter with a grill. Any time I plug in the wall wart that came with the unit, I get S-9 noise on my receiver. The receiver is an Alinco DR-1200. I know it's not the best. But it's what I got. From the material I got with the downconverter, it needs 24 volts. Is that fixed in stone, or can I use something less for voltage? I think I'll try a couple of 12v batteries in series. Has anyone else had the same problem? Any suggestions will be appreciated. 73 and hope to make some more contacts on AO-51. de Doug KA8QCU

AO-51 L/S report
by Andrew Glasbrenner 09 Sep '08

09 Sep '08

I just wanted to report on the fine group the last few nights on L/S. Last night I heard/worked KC9ELU, VE3NPC, and N0JY, and tonight there was VE3NPC and N0JY again, and N8MH and KD8CAO. Signals are strong as always, although there was some buzz on the L band uplink that might be radar related. If you have L/S gear leftover from AO-40, c'mon up and join us this week on AO-51 L/S. Just make sure your CAT cable is hooked up, or your tuning finger is limber! 73, Drew KO4MA

DO-64

If you are looking at the Celestial BBS then you have to load amateur.txt AND go to the bottom of the screen and load Cubesats. DO64 is in there or go to http://www.amsat.org/amsat/ftp/keps/current and download nasabare.txt. Keep in mind that AO-7 in that listing is listed as AO-07. In some programs this makes a difference but some don't. Perry WB8OTH pyantis(a)earthlink.net

LMR 400 Connectors.
by Tony.Corlett＠police.govt.nz 08 Sep '08

08 Sep '08

FYI: Telegartner make Male (Part # B3426) and Female (Part # B3026) Type N crimp connectors for LMR 400 cable. According our local Huber & Suhner agent and cable guru, these will crimp on to both LMR 400 Ultraflex stranded inner cable, and Suhner LMR 400 solid copper inner cable. The inner pins can be soldered on to copper coated solid aluminium inner LMR 400 cable such as Times Microwave. The bodies are nickel plated, and the inner pins are silver plated. Nickel is not reccommended for any professional / large radio site installations because of oxidation / intermod. problems. Suhner and Rosenberger both make slip fit connectors for solid inner LMR 400 cable. Stainless steel bodies with gold plated inner pins. Very high quality, and no special tools required; just a knife!

AO-16 update 8 SEPT 2008
by Mark L. Hammond 08 Sep '08

08 Sep '08

Hello All, As Drew KO4MA communicated recently, it appears that the recent reduction in eclipse/increase in illumination is having a favorable effect on AO-16 and its ability to sustain longer periods of voice operations. Our best theory is that a temperature sensitive hardware timer is responsible for the shutdowns. The current increased illumination periods are causing an increase in spacecraft temperatures (as observed from MBL telemetry). These increased temperatures appear to be favorable for the hardware timer and therefore for AO-16 operations. We are now seeing several hours of operation between transmitter shutdowns. We anticipate that things will improve further in the immediate days/weeks ahead. Current orbit predictions suggest that illumination will improve until mid-October , after which time the eclipses return---and with the eclipses come lower temperatures, and the hardware timer issue returns, shutting down the transmitters every few minutes or so. Sadly, AO-16's orbit is such that after this Sept/Oct/Nov period it will be many, many years before the orbit is again favorable. We encourage you to record your observations of AO-16 on this very useful and intuitive web site: http :// oscar . dcarr .org/ The Command Team uses this site regularly as a means of monitoring the status of AO-16 . It gives us a good idea on the length of time between shutdowns of the transmitter. We also use this site to "announce" that we've turned AO-16 back ON. Friendly advice--if you want to log some AO-16 voice contacts, you had better make them SOON! Mode FM Voice Repeater ( Downlink is DSB . Operation is Intermittent): Semi-Operational Uplink : 145.9200 MHz FM Downlink 437.0260 MHz SSB On behalf of the Command Team, -- Mark L. Hammond [ N8MH ]
