Burns, First of all, I also have an eggbeater on 144 and it does work, however, it is a poor antenna and my preamp for this one is in the shack. I have always advised that anyone that wants to do LEO satellites, needs to put their money into their antenna system- Good coax, good preamp with a directional antenna. Tonites pass at 7:20 local here in NJ was clearly heard by many since it was about 55 degrees. I was just on the local AMSAT net and many heard it. I would take your handheld outside and use the rubber duck to listen Next pass is in about 10 minutes at 22 degrees. Listen on 145.950 +- Doppler and you should hear the voice announcements and the SSTV sigs. Good luck... When it is in eclipse, it is in low power mode. 73, Dee, NB2F

Hi everyone,
Ok, I'm getting very frustrated and I think I need some Elmering. I have not heard ANYTHING from ARRISat-1, at least nothing intelligible. I'm a pretty new ham, so I'm getting into it one piece of equipment at a time. Figured I'd play a bit with a handheld, and then figure out what I needed next step by step. It's been several steps so far with nothing to show for it except some pretty hardware and a smaller bank account. I know a few more things I can do, but I'd really like to know if I have some major problem here. I'll tell you what I'm trying, and I'd like to know if anyone has had success with anything similar.
First, I have an M2 2-meter eggbeater antenna. It is inside the house (my shack is on the 2nd floor, sadly). It has an SSB 2-meter pre-amp, followed immediately by a Diamond 2m/70cm duplexer into a 25-foot feed line. At that point it is connected via an adapter to my Kenwood F6A handheld. I also have an FCD, but with its poor 2-meter filtering, I wanted to eliminate one problem.
A few minutes ago, there was a nice pass from ARRISat-1 here in FN42 (southern NH ); it was in sunlight and had been for some time, should have been up over 50 degrees elevation. Turned everything on, (oh, yes including a 13.8V power supply for the preamp, fed separately). My radio tunes in .005MHz increments, so I started out at 145.955 and tweaked around up and down, shifting to 145.950 and 145.945 as the sat reached and passed max elevation. I *may* have heard vaguely down in the static a voice. I *may* have heard vaguely down in the static some data that might have been SSTV. I may have imagined it.
I *know* I would get better reception outside; I know I would be better off with a directional antenna that had more gain. I can see improving things that way, but is NOTHING a reasonable expectation with this setup? I can receive the NOAA weather station on 162ish MHz (outside the pre-amp's curve but I still get it); I have received the ISS without the preamp (I know that is a lot more power than the sat). So I don't think something is wildly broken. So my question to you is: Have any of you been able to read the sat with anything similar? An eggbeater? I thought I remembered someone receiving on a handheld with a rubber ducky? BTW, someone previous mentioned that I should try listening to some of the other lower-power sats; many of them are 70cm downlink and I have not gotten a 70cm antenna yet.
Thanks for any advice or comparisons.
