IC-W32A versus FT530
by Bill Acito W1PA 12 Aug '11

12 Aug '11

Has anyone owned and used both? I love my FT-530, but I am having a "grass is greener" moment... For those of you have, can you comment on sensitivity? de-sense? programming? controls/interface? availability of headsets? power? (i.e. handheld FM satellite usage) Anything I neglected? Bill W1PA

Future passes
by Dee 12 Aug '11

12 Aug '11

I just did a quick crystal ball analysis and for September, the passes over the US will be more toward normal school hours and we should have more participation of classrooms that are adding this to any courses etc. Presently, there are only a few diehards staying up past bedtime to listen to ARRISat-1. I don't think classroom activity will ramp up until the daytime passes begin. Keep up the publicity. Keep forwarding the important telemetry data to the team. (see upcoming ANS-226 this weekend.)

ARISSat MET
by n0jy＠lavabit.com 12 Aug '11

Seems like the MET is resetting? I could have sworn that the tlm I copied in the 11:00 UTC pass had a MET in the 700s (my memory may be off a bit, could have been 400s?), now it's 323 at 12:40 UTC? I figured that the 700 this morning may have been because it rolled over at 999999 but... Jerry N0JY

Re: Netbooks?
by Dave D 12 Aug '11

Tony I use SatPC32 on a Asus HA1005 series netbook (1.6 gHz,2 geg ram). I have no issues at all. This one has 3 USB ports. In fact that is my main portable PC device. As to a recommendation I use an HP at work for RF walk testing and do not like the quality. The Asus seems so much better. Good luck Dave __________________________________ Dave Donaldson HAM:WB7DRU Navy/MC MARS:NNN0AXK Burnsville, MN Sent from my android device. -----Original Message----- From: ANTHONY JAPHA <tjjapha(a)earthlink.net> To: amsat-bb <amsat-bb(a)amsat.org> Sent: Thu, 11 Aug 2011 7:26 PM Subject: [amsat-bb] Netbooks? AMSATers, Congratulations on getting ARISS going. I hope we learn a great deal from it that will help in future missions. On another matter entirely, has anyone had success running Sat PC32 on a netbook? I operate only as a portable, and am looking for the lightest computer for the purpose. The computer can be very simple, but it must have 2 USB ports (I run 2 FT817s). Do netbooks generally have 2 USB ports? Any other suggestions would be most welcome. Tnx and 73, Tony, N2UN, LM183 _______________________________________________ Sent via AMSAT-BB(a)amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

ARISSat-1 reception report
by nurse Paul 12 Aug '11

12 Aug '11

My call is KA8WWK. I am in Barberton, OH. I heard ARISSat at 2130 hours EST 08/11/11 and 1239 EST 08/12/11 on 145.950 MHz. The radio is a KLM Multi-2700 in FM mode. The antenna is a Cushcraft ARX-250B dual band ringo mounted on my chimney. I can also hear the sat on my HTX-202 handheld with the antenna at an angle to the ground during those times as well. I also was able to receive it in my car using a 1/4 wave vertical trunk mounted using a Yaesu FT-2500M 2M radio!!!! 73's Paul KA8WWK www.myhamshack.com/ka8wwk
