Space Barnacle turned off?
by Greg D. 02 Sep '06

Hi folks, With the delay in the Atlantis launch, I was wondering if PCSAT-2 has already been turned off for good, or if it has a few more days of operations left? Just curious, Greg KO6TH

Cable Informations
by Vincenzo Mone 01 Sep '06

01 Sep '06

Hi to the list, due to change the antenna cables, I would like to know which is the better one at least price For the Satellites activates. Unfortunately I have to use a long descent. I want also install my old 23 elements antenna for the 1,2 GHz. So the cable should be all for the satellites activates and should be for 2 meters 70 centimetres 23 centimetres I would like also to get a Mast preamplifier for the 23 centimetres. I already have the Mast preamplifier for the 2 meters and the 70 centimetres. They are both from Dressler and both has the EVV Interface. Please let me know which one is the better one at least price and if it needs also of the interface. Please let me know prices and where to get them Any suggestion will be really appreciated. Thanks in advance. 73 de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

ECHO
by McGrane 01 Sep '06

01 Sep '06

greetings I would like to report very poor reception of echo even with an 8 element yagi and an 18 Db preamp. I assume the downlink power is real flea power for battery charging or other testing. After 2 years of pleading with amsat, the downlink power is still a mystery. It is not shown on the colaradosatellite telemetry graphs (TX B) or the amsat website, after repeated requests here and elsewhere I'll assume it is being held secret for some reason. There has been a tremendous lack of technical reporting on ECHO. I realize people are very busy but time should be taken to educate the amsat community. 73, patrick N2OEQ 32323

Last call for instock 2.4 GHz downconverters
by k5gna＠houston.rr.com 01 Sep '06

01 Sep '06

To: All, from Bob, K5GNA Please respond to: k5gna(a)aol.com -- replying to the Road Runner address on this Email will only delay a response. I have Fourteen (14) of the AIDC 2.4 GHz downconverters packages left that are packed and ready to ship, except for sealing. I have shipped a lot of these downconverters in the last few years, but I am not restocking these downconverters until we have another HEO satellite up, or if there should be enough demand (enough on a waiting list) for 2.4 GHz receive in the near future. THIS MAY BE YOUR LAST CHANCE TO GET ONE FOR A WHILE. These packages include about everything you will need to receive AO-51 for portable or even fixed operation, except the FM receiver and battery. The package will include the following: AIDC 3731 downconverter with 37 dB of gain, good for 13.8 VDC operation, retuned for 2.4 GHz, with a 2 meter IF crystal @ $105.00; 12 dBi corner reflector @ $27.00; Power inserter @ $10.00; 6 dB attenuator @ $3.00; 3' and 12' jumper for portable operation @ $5.00; F female to BNC male adapter @ $3.00; Shipping, handling and insurance in the USA @ $10.00. TOTALl = $163.00 SHIPPING OVERSEAS WOULD ADD AN ADDITIONAL $20.00. Just for the AMSAT BB -- I will also include the following 2 items at NO CHARGE: (1) N adapter for future use with a larger dish and feed (normally @ $ 5.00) (2) Wall wart power supply with weird connector -- simply cut it and splice it into a short F cable -- but since it is 110VAC, it is not for overseas. (normally @ $5.00). The remaining units not taken on the Amsat BB will go on Ebay in few days, but without the 2 giveaways. I also have some 2.4 GHz signal sources for $17.50, plus $8.00 shipping and handling in the USA. These are Gardiner downconverters that without modifications will produce a signal at about 2399.875 MHz (or 143.875 MHz in your RX). I also include a crystal (solders to the top of the PC board) to come out at about 2400.020 (or 144.020 MHz in your RX). I have a few of the 12 dBi corner reflectors that clip onto the AIDC downconverters available separately at $27.00 each plus shipping and handling. I could also add the signal sources to the downconverter packages, plus I could replace the 12' portable sized cable with a 50' cable for fixed use -- please inqure. Please respond to me at k5gna(a)aol.com if you want someting and I will send you complete details on paying, etc. Bob K5GNA k5gna(a)aol.com

Mobile QSO on VO-52
by Luc Leblanc VE2DWE 01 Sep '06

01 Sep '06

Hi all On my lunch break i was able to make a QSO with VE3BSB James in his car running. It was my first QSO with a mobile station on a Transponder type satellite in SSB. I was testting an old KLM 2M 14C on the downlink and i was using a 7.5' dish on the uplink. The power setting was at 0 on my FT-847. The hic with low TX power make us often unhearded by some stations and i have to often crank up my power to be able to make the other party hear me. But on this QSO i was able to keep my power at 0 or near that as the 847 still transmit some wattage my last preamp knows it... "-" The medium is the message...The content is the audience...;) Luc Leblanc VE2DWE Skype VE2DWE www.qsl.net/ve2dwe "-"

ECHO duty cycle
by McGrane 01 Sep '06

01 Sep '06

hello again- Does anyone know what percentage of a day or orbit the echo transmitters are ON? I've been thinking about the battery depth of discharge issue. Being that they are as a whole 4 amp hours, a 10 percent discharge would equate to about 1.6 amps for one quarter of an orbit on-time. According to drew, the transmitters are drawing about .8 amps. I hope people are viewing depth of discharge as a function of amp-hours more than voltage ( I realize also important ). Any comments are welcome. Thanks, pat n2oeq
