WX sat software
by Philip Jenkins 13 Mar '19

13 Mar '19

I got this email from a guy I met at the Charlotte Hamfest. I know extremely little about receiving WX sats, so I told him I'd pass it on the AMSAT BB. Email him directly if you like.... avampato(a)comporium.net There is one correction to the email below. He actually meant NOAA 19, not 21. *Philip,* *Remember we met at the Charlotte Ham fest. What I wanted to know is what software is used to demodulate and display NOAA 21 Sat images. I receive a strong signal when the sat is overhead. I watched the utube videos, but they didn't help.* *Thanks,* *Joe Avampato* *W8DKR* Philip N4HF

Tuning above 435.360 MHz when working AO-92 U/V??
by Patrick STODDARD (WD9EWK/VA7EWK) 13 Mar '19

13 Mar '19

Hi! A couple of weeks ago, when I started using my old Icom IC-W32A on the FM satellites again, I saw that I was having to tune up to 435.365 MHz on the AO-92 U/V uplink to get through near my LOS. I didn't think much about it then, since the radio is at least 15 years old. It worked, even with the additional tuning step, and did a decent job on AO-91 and AO-92 (U/V). It's one of the later W32A models, with a 7-digit serial number that doesn't include any capabilities to receive at 800 MHz, and doesn't work SO-50 full-duplex. I was on AO-92 U/V earlier this week using my TH-D72 HT. On one pass Monday morning, I found that I had to tune up to 435.365 MHz near the end of a pass to get through the satellite. This was the first time I could recall having to do this with my TH-D72. I asked about this on Twitter and the QRZ satellite forum; a few others have noticed the same thing. I am now finding that when I work AO-92 U/V, I don't stay on 435.340 MHz very long. Maybe a minute or so, about the same amount of time I have been on 435.365 MHz before LOS. I spend a similar amount of time on the other 4 tuning steps for AO-92 U/V (435.345 through 435.360 MHz). Once I saw this, it is not a big deal to be prepared to use a 6th tuning step on my radios. This is a relatively new thing, as I wasn't having to tune above 435.360 MHz a year ago - or even 3-4 months ago - when working AO-92 U/V. For those using HTs or FM mobile radios to work AO-92 U/V, does anyone else find they are having to transmit above 435.360 MHz late in those passes to get through? If you're using something like an IC-910 or IC-9100, where are your radios ending up when working AO-92 U/V? Or an alternative question... what are you using as the nominal uplink frequency for AO-92 U/V? Thanks, and 73!

JAMSAT Phase 4 Ground and Space meetup
by Michelle Thompson 13 Mar '19

13 Mar '19

I’ll be speaking and doing demonstrations at JAMSAT Symposium this weekend. If any one is there, and wants to meet up, please let me know! Focus is on how we use GNU Radio on Phase 4 Ground and why it’s such a great tool for amateur radio experimentation. We are on deck on Sunday. Work on broadband microwave digital system GEO and ground stations for North America continues and has made some big steps forward lately. Read about recent activities at https://openresearch.institute, or in AMSAT-NA Journal when they have space. -Michelle W5NYV -- -Michelle W5NYV "Potestatem obscuri lateris nescis."

Re: [amsat-bb] Shoppinglist

Hans, I was going to recommend the same RTL-SDR.com filters, with the caveat that you cannot transmit through them. This shouldn't be a problem if you are using an arrow (just be sure to not TX on the antenna it's connected to), though? (somebody can correct me if I am wrong). I will say that I researched band reject filters a while ago that can take significant power, and they are REALLY expensive (like $100 and up). I own one of these cheap RTL-SDR.com FM filters and it does work (although I've never used it for sat ops). --Roy K3RLD > I doubt these can take more than a few Watts. I want something you can > use for higher power. Thanks for the link, though.

Hawaii contact
by Douglas Tabor 13 Mar '19

13 Mar '19

Looking for a Hawaii station for an AO-7 contact from RE66 - should be situated around the 28th of March at a place where I should have a slightly negative horizon. Appears to be 2 short passes a day. Any takers from Hawaii? 73, Doug Douglas Tabor, N6UA dtabor52(a)gmail.com

by Bob Keating 12 Mar '19

12 Mar '19

Just a note to all whom I had QSOs with this past weekend... I am in the process of uploading all contacts to LoTW and should be done by tomorrow. Not sure if it makes a difference, but my call sign is showing up as N6REK/P on my logged QSOs. Thanks to everyone who responded to me. 73, Bob N6REK

Hi all I am looking for any advice or information through which I can receive satellite telemtry related to seismic data . any one who have received such satellite payload using amateur satellite ground station ,please provide the name of satellite and receiving satellite ground station specification . I have found Twinsat-1N nanosatellite mission flown on QB50 project but it was unsuccessful mission. looking for information about satellite with seismic data payload whether nano/cubesat which are currently in orbit and whose satellite pass can be received. Thanks and regards shakeel
