I do not operate eme on 432+ but I believe that normal calling is done on 2-1/2 minute sequences. I suspect that will not be done with Arecibo (but they should say what their operating protocol will be). Normal eme protocol goes like this: CQ de KP4AO calls for 2.5 minutes KP4AO de KL7UW means KL7UW copied KP4AO call sign (not calling in the blind); calls for 2.5 minutes KL7UW de KP4AO signal report (May be RST or OOO); also means Arecibo copied both KP4AO and KL7UW's call sign; gives report for 2.5 minutes KP4AO de KL7UW roger your report (RO) and/or RST; for 2.5 minutes KL7UW de KP4AO RRR means I copied your report; for 2.5 minutes KP4AO de KL7UW 73 and SK; end of successful contact; for 2.5 minutes total time 15-minutes So with 2:45 hours of operation 11 QSO's could be made; so I do not expect the usual 2.5 minute time sequence. That is usual for CW and digital eme, but I do not know what is likely to ensue with the expected pile up on SSB. But for proper eme both calls must be given and confirmed (unlike HF were only one call is stated and the other station, assumed). 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-600w, 432-100w, 1296-60w, 3400-fall 2010 DUBUS Magazine USA Rep dubususa(a)hotmail.com ======================================

Circular polarisation question
by Phil 15 Apr '10

15 Apr '10

Thank you for reading this. Ten years ago I built a pair of circular polarised aerials primarily for satellite use. The UHF aerial has 12 elements in each plane while the VHF aerial has 6 elements in each plane. My UHF received signal strength often seems to be below that of other stations and so I'm rethinking how I have set up these aerials. The received signal strength via VO-52 is S7 at the best, without a pre-amplifier, and so I'm happy with that. The UHF aerial is where the problem is even thought they are set up in the same way. Both aerials are mounted in an X orientation. One set of elements is a quarter wave ahead of the other set. Because of the X mounting I cannot tell if the vertical set is ahead of the horizontal set or not. Each aerial is fed via a power splitter via equal length cables. My question is; does this sound like a correctly set up right hand polarised aerial? Originally I thought it was now I'm not sure. -- Regards, Phil

Re: Settings to work HO-68 in FM
by Nader Omer 15 Apr '10

Hi Fran EA1JM and All Many things can be the cause 1-Check up your receiving setup ! listen to beacon before you transmit . 2- some time the sat not changed to FM mode (happened few time ) instead of the schedule stats so. 3- check the beacon to see which mode is on. 4-AFC in downlink shift the frequency so fast ,so deactivate it until you hook with strong down link signal. 5-Never Try to work FM satellite in IC-910 sat-mode . IMHO IC-910 sat mode is perfect only for Xponder satellite. 6- check volume level! and check if the tone on the VHF and not on UHF.(common mistake to mix uplink tone with downlink tone) 7-Check Main and Sub External speaker setting combination Hope this help! 73 de Nader

SatPC32
by Roger Swickis 15 Apr '10

15 Apr '10

Dear Folks, I am attempting to get myself back on the satellites and am having some problems with SatPC32. Although WinAOS gives me accurate satellite position data, SatPC32 does not. Furthermore satellite AOS/LOS data is different between the two programs, sometimes by a half an hour. I have checked all the settings and have tried updating the Keps but can't seem to get the program to display accurate data. Has anyone had this problem or does anyone know if there way around this other than re-installing SatPC32? (I'd rather not have to input all the settings again if I don't have to.) Thanks Roger VA7MG

AO-7 "situation"
by Bob- W7LRD 15 Apr '10

15 Apr '10

Hello Just got off AO-7, it really sounds not too good. Weak and distorted audio. Like not enough voltage from the 35 year old solar cells. Heard eveything from response to a CME event to being in mode C to being hit by whatever. The audio distortion does not depend on the uplink power, it sounds distorted weather I ran very minimum power or more. I know we are simply "blessed" to have this old bucket of bolts for our enjoyment. Perhaps some our experts on the bb can shed some of their expertise on what's going on with this old bucket. 73 Bob W7LRD

I wonder if a robot operator would make a 2-way QSO from the ISS using a ham radio transceiver? See the video... amazing development: http://www.youtube.com/watch?v=lY-SJyS18lA&feature=player_embedded http://news.cnet.com/8301-17912_3-20002479-72.html 73 de N3RDX & S21X

Settings to work HO-68 in FM
by Francisco Jiménez-Martín Sánchez 14 Apr '10

14 Apr '10

Hello to all the people in the list, I would like to know if you use any special setting to work the HO-68 sat in FM, because I have tried for to two days to enter in the satellite with no success. I have an icom IC-910H, with the pl tone of 67 in the uplink but there is no way to enter in the sat. I have tested to increase the power or decrease and tried to follow the sat the best way possible with my yaesu g-5500 and my X-Quad wimo antennas with no luck. Do you have any recommendation? Thanks in advance for your replies. Kr, Fran EA1JM
