Need help finding a sat antenna

Chuck Freeman <w0cbf@...>
 

Hello, I am handicapped and building an antenna is out of the question. Also using a handheld beam will not work. I am looking for a turnstile antenna that is available to buy. I have been trying to listen to SO-50 with a dipole inside antenna without any luck. Any help w UK ll be greatly appreciated. 73's de Chuck W0CBF

Hello, I would highly suggest you look for an SMA to BNC cable adapter to take the strain from the coax off of the connector on your Kenwood TH-D72. These cable adapters usually use a coax such as RG-174 which is very flexible.

I found these on Amazon, support at the base. Work well for me.

Just use a long length RG-058 patch lead SMA to the BNC to take any strain off the D-72, and not directly into the Arrow.

Hi There,
I have a Kenwood TH-D72, and an Arrow II antenna. I’m trying my luck with the SMA-BNC connector that is sold along with the signal stick antenna, which looks like the diamond adapter minus the rubber sleeve on the outside of the bottom portion, and it’s $4 so not a huge risk if it doesn’t turn out to be wide enough. Assuming that doesn’t work out, what do people use nowadays? I saw an old post on this from 2010 that mentions "Stephen's Model # BGA-76 will fit your Kenwood TH-D72A radio perfectly”. But I’m not sure how/if you can still get those easily, or if people are using different ones now? 

The other question I have is around connectors that have a rotating hinge. When I bought my arrow antenna, and purchased their $7 BNC/SMA adapter alongside it. Their adapter is super narrow at the base, and seems to transfer a lot of the side-to-side strain from the cable to the SMA plug, which I don’t like. One feature that was nice about it though is that it has a rotating hinge so it’s easy to rotate the radio as I’m flailing around with the antenna looking for a signal (I’m pretty new at this :). I noticed that the rotating hinge was getting some pretty heavy use. To get at something similar I found a BNC Female to BNC Male adapter on amazon that has a rotating hinge in it, which I was planning on attaching to the arrow and leaving there, since it seems like the Gulyas and similar adapters do not have this rotating property.

Thanks for your tips!

Best,
John

ARISS / ISS Equipment UPDATE 03/02/2021

Clint Bradford
 

All,

 

The ARISS team has been working very closely with NASA and ESA to identify potential ARISS radio anomaly causes and resolve the radio issues that were observed after the EVA (spacewalk) conducted on January 27.  During this spacewalk, cabling was installed to support the commissioning of the Bartolomeo attached payload capability mounted on the Columbus module.  Part of this cabling rerouted the cabling of the ARISS antenna on Columbus to the ARISS radio system.  

 

Through a great deal of coordination with NASA and ESA, ARISS will be conducting a set of APRS tests to determine the operational use of the ARISS radio system in Columbus through employment of three different cabling configurations.  Over the next couple of days, ARISS will be performing a series of tests using our APRS capability through the standard 145.825 MHz APRS frequency.  The crew will be periodically shutting down the radio and swapping cables so ARISS can troubleshoot the radio system and the cabling.  ARISS is unsure of the exact swap times as it will be dependent upon the crew’s availability.  We expect these tests to start no earlier than 1600 UTC on March 2 and run through sometime on March 3.  We cannot guarantee that these troubleshooting tests will resolve the radio issue.  But we encourage ARISS APRS operations in this time span.  Additionally, a contingency task has been approved for an EVA planned for this Friday March 5 if these tests are unsuccessful. This EVA task would return the ARISS cabling to the original configuration prior to the January 27 EVA. Being a contingency task means the crew  will only be perform the activity if time allows.  So there is no guarantee that this EVA will be conducted on Friday.

 

We ask to please not send any “No contact” e-mails or social media responses as this will overwhelm the ARISS team.  But if you definitely hear the packet system working or are able to connect through it, let us know the Date, Time and Grid Square of the occurrence.  

 

We thank you for your patience as we work through this somewhat complex anomaly.

 

73,

GoSatWatch and the ISS

Clint Bradford
 

February 25, 2021 – Unable to update orbital data
NASA has decommissioned the server the apps use to update the orbital information for the International Space Station. As a result the GoSatWatch app by default and GoISSWatch app no longer accurately track the ISS.

GoSatWatch: The app settings can be modified to use an alternate server. From Settings > Orbital Elements > Int’l Space Station > change the URL to https://www.n2yo.com/satellite/?s=25544 or https://www.heavens-above.com/orbit.aspx?satid=25544. The Space Station Missions group can still be used for accurate ISS station tracking as it uses a different server for orbital data.

GoISSWatch
: An update is in the works to use an alternate server. In the mean time please contact support for a temporary code to download the full GoSatWatch version.

Ten Years Ago ...

A friend just sent me this ... from ten years ago ... makes one feel REALLY old ...

K6LCS satellite presentation at the Anchorage Hamfest

Craig Bledsoe, KL4E of the Anchorage Amateur Radio Club (AARC) noted their September 17 Hamfest featured a first-ever, remotely-delivered keynote presentation by Clint Bradford, K6LCS.

In order to facilitate this full-duplex two-way video Skype conference between Clint's studio in Riverside, California and the Anchorage Hamfest a team of hams assembled the technology to make this happen.

Led by Rich Gillin, AL4S, and Eric Thompson, N6SPP, the team installed an AT&T active remote phased-array WiMax antenna at the hamfest and aimed it towards the AT&T Alascom headquarters on Government Hill many miles away. The resultant broadband signal enabled Clint to present over a hundred PowerPoint slides through a laptop computer and projection system while his audio was delivered via a Skype connection. Two way internet video streaming allowed the audience to see Clint and he was able to see the crowd at the Hamfest.

Clint delivered a fascinating look across the spectrum of amateur satellite operations. From the earliest days of the first OSCAR satellites first launched over a half-century ago to the organization of AMSAT and today's comprehensive international efforts to get the latest amateur technologies into outer space, his presentation covered it all.

Clint also taught the basics, showing step-by-step how a beginning ham can use a simple handheld radio and antenna to work the satellites with great success.

In addition to all of the on-line satellite discussions, the AARC also conducted real-life satellite QSOs from the hamfest before and after Clint's presentation. Using AO-27, SO-50, and AO51 the host operators N6SPP and KL4E worked over a dozen amateur satellite stations in three countries. Then a number of guest operators who were attending the Hamfest got on board as well. Several visiting hams made their first satellite QSOs that day - and they were thrilled!

All-in-all everyone had a great time at the Anchorage Amateur Radio Club Hamfest, and many visitors said that they thoroughly enjoyed Clint's presentation.

I understand that 50 is a weak signal unit and that a yagi antenna will cut the mustard.

However that's outside my effort budget and I really don't want to be taking my dog for a walk carrying a yagi and 
waving it around at an invisible UFO lol. I did so enjoy AO-91 with a simple antenna and was able to work ZL and VK 
easily and it was so darn cool!!!

I work SO-50 almost every day with an Arrow and a 5W HT. I only had to turn the timer on one time and that was about 4am EST local and I was the only person on the bird. All the other times it was already being actively used by multiple hams.

You will need a Arrow 8 el UHF and 3 el vhf to work SO50.The downlink from the sat is less than 100 mw 73s de VU2PEP

Mike,

You need to transmit a 74.4 Hz tone for 2 seconds to activate SO-50. Then it’s active for 10 minutes and can be accessed using the 67.0 Hz tone.

If you’re in an RF noisy environment, SO-50 is going to be tough to hear with a whip. I did work SO-50 from horizon to horizon with that same antenna out on a beach overlooking Lake Michigan once, but ideally you’d use a directional antenna. Here in the center of Washington, DC, I cannot hear SO-50 at all with any sort of whip antenna.

Since it's demise I have tried PO-101 (can hear it's CW beacon) and SO-50 (silent). I miss AO-91, such a great beacon with the female voice.
