A bandpass filter may help. Here is one from MFJ for 2 meters. http://www.mfjenterprises.com/products.php?prodid=MFJ-713 The above has BNC connectors, the MFJ-714 has SO-239 connectors. ron w8gus

Amen, Andy! Excellent explaination. I can't use my Yaesu VX-5R HT with an Arrow attached in a metropolotin area for the very reasons you describe. It works fine with a long "Rubber Duck" but with all of the aluminum in the Arrow attached it becomes very deaf due to front end overload. 73 - Keith, W5IU

In a message dated 26/08/2006 16:33:29 GMT Standard Time, tmcgrane(a)suffolk.lib.ny.us writes: Thanks for the info drew and bob, with at least 18 watts from the solar panels and maybe 6 watts being consumed by the satellite, I believe there must be a way to recoup all that solar power. Thanks to anybody who can eek out more power in the future. Can amsat afford to consult with the original satellite manufacturer in virginia on the subject? BTW, I have bothe the original and current ECHO books. Thanks, pat n2oeq Hi Pat. The answer would seem to be: Echo works very well at it's current power setting requiring only modest equipment to use the onboard systems. To receive the satellite down to the horizon on every pass could be done by increasing the power towards its maximum of 4 Watts. However, the penalty would be to limit the other functions available to users and increase the depth of discharge of the batteries during each eclipse period. The effect of this would be to shortern the life of the batteries and the satellite. All of the above gleaned from messages and material referenced in the past few days. We don't need to ask Spacequest anything, we just need to improve our ground stations to cope with the power that is deemed optimum for maximum satellite lifespan. 73 David G0MIN AMSAT 51 on 51 award No fortysomething.

echo
by McGrane 26 Aug '06

greetings Please note I am not mad at amsat so please dont take my messages so personally. Just trying to report my observations then things get carried away. The coloradosatellite telemetry graphs only show TX A power which is the digital transmitter. I am interested in the TX B which is the phone transmitter. Thanks for the info drew and bob, with at least 18 watts from the solar panels and maybe 6 watts being consumed by the satellite, I believe there must be a way to recoup all that solar power. Thanks to anybody who can eek out more power in the future. Can amsat afford to consult with the original satellite manufacturer in virginia on the subject?

I guess you know by now that Enzo meant non-amateur up-/down-link frequencies. I think that Trevor M5AKA and others (me!) have posted some suggestions. However, as an insider perhaps you could publish a definitive list of good places to listen during launch and docking. See also www.dxtuners.com where the local Florida nodes tune in to launch frequencies. 73 de Félim M3HIM IO91ot Aylesbury, Buckinghamshire, UK ----- Original Message ----- From: "Ransom, Kenneth G.

Felim, Here are some helix info websites. 1.http://www.qsl.net/ve3cvg/antennas/ Good antenna website plus 2400 MHz helix. 2.http://www3.sympatico.ca/b.zauhar/ A lot of info on this page with 2400 and 435 MHz helix projects. 3.http://www.g6lvb.com/index.htm Great site! Check out quadruple helix for AO40. 4.http://members.aol.com/k5oe/ Jerry's site has a lot of useful helix data. Check out the helix projects by clicking the home brew page at left bottom. 5.http://www.electric-web.org/2m_helix_antenna.htm VK5ZAI's 2 meter helix 6.http://webpages.charter.net/n4wyk/ Click satellite website then click 2401 MHz helix at left. 7. The 2006 ARRL Handbook has a excellent "L" band helix project. If I can be of any further assistance, please email. 73, Mike K9QHO AMSAT 33589
