How to Work Ham Sats tutorial updated

K6LCS <clintbrad4d@...>
 

I just updated my four-page tutorial that gets you working the FM sats with equipment you probably already own. One change is the addition of a single Web page with all the URLs and resources mentioned in the document. Download a copy of the handout at ...

ANTENNAS for HTs

K6LCS <clintbrad4d@...>
 

During my presentations, I show folks these HT antenna improvements ...

- Smiley 270A ($15), BNC or SMA

- Diamond SRH-320A ($50), SMA

- Pryme AL-800 ($40), BNC)

- Arrow 146/437-10WBP ($130), BNC

This, of course, is by no means an all-inclusive list! What antennas are YOU having success with workin' the satellites?

Clint

SOFTWARE for Satellite Tracking

K6LCS <clintbrad4d@...>
 

There are several software programs available for tracking amateur satellites. What program(s) have YOU settled upon to use for working the birds?

Clint

Which RADIO Should I Buy?

K6LCS <clintbrad4d@...>
 

Ahhh ... the age-old question. Ask this question in any ham club, and you'll receive many differing answers!

The main point of my presentations is to show fellow hams that they just might already have the necessary equipment to work the FM satellites: a handheld radio capable of "split freqs" (where it can TX on 2M and RX on 440), and an antenna improvement to that radio.

There's only one true, full-duplex radio on the market right now ... but, unfortunately, that Alinco model suffers some sub-band sensitivity problems. Whether or not it can be cured with future firmware releases is unknown.

A definition is in order: true "full duplex" means that one can monitor one band while keying the mic on another. The Kenwood TH-F6a, for example, is a dual-receive unit with its independent VFOs - but not true "full duplex," as you cannot monitor anything while the PT is pressed.

SO ... What are you using? Icom's IC-W32a? Yaesu's little VX-3R? My current favorite HT for sat work - the Yaesu FT-60R?

Not active right now but have a Yaseu FT-530 and a Kenwood THD-7.

Orbitron gets great reviews, indeed!

John - what are the top two or three features that you really like about Orbitron?

Clint

Handicapped Access?

K6LCS <clintbrad4d@...>
 

From a friend via email ...

... I always see hams standing while using Arrow Antennas and HTs for their satellite contacts. I use a front wheel walker so I can't carry very much equipment with me. I've always stayed away from making satellite contacts because of my disability. Any ideas on what I can do? Any suggestions you have are appreciated.


Well, the higher elevation passes can be worked with just an improved whip on your HT!

If your radio has a BNC connection, then the Pryme AL-800 will do it.

If you are SMA, then the Smiley 270A or one of those super-flexible 17" whips will do.

I show 'em all at my presentations. (And this gentleman is local to me, and we'll meet up next week!)

Hi Clint,

I appreciate your time and effort in getting this group started.

I appreciate your time and effort in getting this group started.
Thanks, Scott!

I have NINE presentations scheduled September-November ... interest is picking back up!

And as I explained on the Web site, I don't have time in a one-hour presentation (nor space in a four-page tutorial!) to cover ALL antennas, radios, software programs, et al for workin' the birds. So let's use this YahooGroup to supplement the basics, and enhance our experiences.

And enjoy this magnificent hobby!

BNC-to-SMA Adapters - 09/30/09 Update

K6LCS <clintbrad4d@...>
 

Just received this reply from Stephen regarding his EXCELLENT BNC-to-SMA adapters. They are made with a hard rubber collar that "mates" wit the case of your radio - to better protect your delicate SMA connector.

The Yaesu CN-3 adapter, on the other hand, should be banned from the marketplace, as it provides absolutely NO protection to your radio from stress and strain at the antenna jack.

Which Arrow Antenna Model???

K6LCS <clintbrad4d@...>
 

From the email folder ...

Q. I stopped at HRO a few days ago to buy an Arrow beam antenna for satellite work. They had a small one that breaks down and a bigger on that costs less. The small one has a duplexer? Which do you use?


A. I use Model 146/437-10WBP - the one with the duplexer built into the handle. Just one coax line to a single HT. It terminates in a BNC connector. If your radio is SMA, then Comet makes 18" jumpers of rewally flexible coax (less than 1/3dB loss - no problem). Or use one of Stephen Gulyas' EXCELLENT BNC-to-SMA adapters - which actually provide protection for your radio's antenna connector.

Work Sat Tutorial

K6LCS <clintbrad4d@...>
 

A valued member here yesterday submitted a URL to a 10-page "How to Work Sats ..." article that appears elsewhere on the Web.

I welcome such participation! KNOWLEDGE IS POWER.

But while reading the document, I saw errors: bad or outdated URLs ... improper frequency chart for AO-51 (still had a CTCSS for TX, which we haven't used for years) ... improper on-the-air protocol ...

So I am not going to post the URL to that document. I'll watch it, though, in case the author updates it!

EchoLink Show - TONIGHT - 5:30PM Pacific / 8:30PM Eastern

K6LCS <clintbrad4d@...>
 

I'll be on the SCARS Network - EchoLink Node 96140 - tonight to discuss working the FM satellites with your handheld radios.

Grab this .pdf file to follow along (NOT mandatory!) at the bottom of the page ...

Re: SOFTWARE for Satellite Tracking

Hi Clint,

Thank you very much for starting this group. I have been using your "HT" document to get started with Satellites and begin my journey of education and fun. I do not have the experience to begin transmitting as I'm still figuring out how to use the AL-800 with my VX7R to achieve the best signal. I have listened several times on various satellites as they pass over, but no transmissions. My day is coming...

I have been tinkering with Satscape. I first like that it is multi-platform (Windows, Unix, etc). I also like the views that if offers - 2D and 3D views of earth. Finally, I like that I can customize what is on my maps -- I can have as many or as few as I want.

Again, thanks for starting this group and allowing people like me to have a forum to learn...

Thanks,

Mike, K4MOA

THANKS for participating here!

... how to use the AL-800 with my VX7R ...
CAUTION! Please do NOT use the Yaesu CN-3 BNC-to-SMA all-metal adapter. It provides absolutely NO protection for your radio's SMA antenna connector.

That antenna is very heavy and places a lot of strain on your connector ... Look at the Stephen Gulyas adapters on my Web site at ...

But please STILL try to support the antenna-HT as you use it ... cradle it carefully ...

... I have listened ... but no transmissions ...
Hey - I was at that same point a couple years ago. Go for it!

Clint

Re: SOFTWARE for Satellite Tracking

MichaelE <k4moa@...>
 

I actually purchased Stephen's adapter prior to getting the AL-800. You can tell that there is some support with the adapter, but like you said - still need to be careful. I must admit it is still sort of an odd feeling the way you need to hold the radio and antenna in the same hand then try to move around to find the best signal. I'm enjoying the challenge -

Thank you again for all of your work and advice -

Mike, K4MOA
