You can HEAR AO-91, AO-92 and the ISS Packet and SSTV ...

If the passes are on that side of the house.

Got an HT? An HT with modest home-brew antenna improvement will 
be more satisfying!


Inexpensive Base Station: Will This Work?

Kent K5KNT
 

Hi all,

I'm a new member to the group and it has been a long time since I worked the sats. The last time was just over 11 years ago. At the time, I was using my mobile rig, an Icom IC-2720H with an 18-inch whip antenna. I began having issues with the radio powering off at intermittent times so I pulled it from my car and sent it to a repair shop. They sent it back and said they couldn't find anything wrong with the radio. I lost interest in the hobby and never bothered to reinstall the radio. Now, two moves and two different states later I've decided to give it a try again. 

I will be moving to a different house sometime this summer/fall so I'd rather not bother with an outside antenna at this time. I'm wondering if I could use the 18-inch whip indoors (near a window) with the Icom and get any results.  What are your thoughts?

Thanks,

Kent, K5KNT

FYI, the SEC-1235M (Samlex with meters) is only $129.99 at Universal Radio.

That is quite a footprint for both AO-92 and SO-50. Maybe some day I will
be able to contact you on one of those SATS here from S.E. Michigan.

Clint, Thanks for posting both the original 'idea' and the article. 

It was on my mind to encourage a few newer hams to take some time right now to add resources to their stations and a solid power supply was on the list.

The 30A continuous output of the 1235M and $145 shipped seems to make it the deal of the day.

Clint,
I'm not where I can look at the ARRL archives.  Was that one of the switching power supplies that the ARRL labs examined and reviewed years back?

I would certainly try AO-91 and AO-92!

AO-91 is always in UHF UP - VHF DOWN mode ... '92 switches to 1.2gHZ UP - VHF DOWN 
for a day a week ...

Do NOT use that program's frequencies ... stick with the proven chart on the

WELCOME to this exciting aspect of our hobby. YOU ARE SO CLOSE to 

success!!!

 

>> … Anytone 868 and Yaesu FT60 …

 

I think the FT-60’s receiver is a little more sensitive … BUT - You are 

using an antenna system with a lot of gain! Working ’50, ’91, and ’92 

will be easy!

 

>> … Arrow Antenna …

 

WITH or WITHOUT the diplexer?

 

>> … SO-50, but in all the excitement I forgot to adjust for the doppler shift.  

 

No biggie … just tune a little ABOVE to start the pass … then to the transmitted 

frequency … then slightly BELOW as it descends …

 

SO-50’s 2M Uplink - NO Doppler correction.

 

>> …I tried the ISS earlier this morning, but never heard anything. 

 

Nope. Not FM voice … but Packet is up!

 

>> … What is Mean Anomaly?

 

Huh - you SHOUDL know that. It is Question 1,234.789(c) in any exam …

 

(GRIN)

 

It represents the fraction of an elliptical orbit's period that has elapsed since the orbiting body passed periapsis …

 

You DON’T need to know this … seriously!

New member and a couple questions

K9DWI
 

I am new to the group and very interested in making my first QSO via Satellite radio.  I am in the Kansas City MO area and enjoy local simplex/repeaters, HF, and digital.  Anyways, I have two handhelds (Anytone 868 and Yaesu FT60) dedicated at the moment for satellite use and just picked up an Arrow Antenna  (146/437-10 LEO Satellite Antenna).  I have yet to make a contact and just a few minutes ago I managed to hear SO-50, but in all the excitement I forgot to adjust for the doppler shift.  It was busy and waited for a break to call, but that didn't happen.

I tried the ISS earlier this morning, but never heard anything.  Will I hear anything if the astronauts are not on the radio?

I attached a screenshot and I believe I have a good concept of the AOS, TCO, and LOS.  I did have a question on elevation according to this attachment.  If the satellite was directly overhead (center of screen) it would be at 90 degrees?  I added green numbers which I believe would relate to degrees in elevation.  Am I on the right track?

What is Mean Anomaly?

Thanks so much...
