EME Station 2.0 Part 10 – Antennas On The Tower

After a year’s worth of planning and 10 months of construction, we have our new 2m EME Antenna System installed on our EME Tower and working! This stage of our project took about a week…

We’re making good progress on a new 2m EME Antenna System here at AB1OC-AB1QB. Our Antenanns system is up on our EME Tower and we are working through the setup and integration of the equipment and software for our EME Station.

We rented a boom lift and worked with Matt and Andrew from XX Towers to get our Antenna System up. Our antenna installation took a week to complete and it turned out quite well.

You can read all about this step in our project via the link above. We should have the work needed to bring the rest of our EME Station together sometime during the next few weeks. We can already receive signals that other Hams are reflecting off the moon!

The link above provides the details and the information needed to access the ISS Voice Repeater.

I was able to work several stations using the new Voice Repeater this morning. It is very sensitive and uses 5 watts of downlink power with a good antenna on the ISS. I was able to make solid contacts using the Ground Station here using only 1.5 watts uplink power when the ISS was at 10 degrees above the horizon. At least one of my contacts was with a station using an HT with a whip antenna!

The voice repeater is sensitive enough and uses a power level that will enable folks with an HT and a whip antenna to make contacts using the ISS when its close to the horizon. It should also be easy to make contacts using mobile rigs that can support cross-band operation as well. Program your radios!

I’m looking forward to working you through the ISS!

AO-27 Satellite Is Back On The Air!

The AO-27 FM satellite is back on the air! It is an FM V/U Mode satellite that was launched back in 1993. The satellite’s Amateur Radio payload became inoperative about 7 years ago due to …

The AO-27 FM satellite is back on the air! This satellite is an FM V/U Mode satellite that was launched back in 1993. The satellite is back on the air on a limited-time basis (4 minutes, twice per orbit over the mid-latitudes).

I was able to make my first contact through AO-27 this morning. The contact was with AI9IN in Indiana, USA. I’m looking forward to making more contacts using this satellite in the near future.

You can learn more about this satellite and how to make contacts using it via the link above. I hope to contact you on it sometime soon.
