Delfi-n3Xt Update

Delfi-n3Xt Satellite

Delfi-n3Xt Satellite

The Delfi-n3Xt has a 435/145 MHz linear transponder and is on the November 21 Dnepr launch. Jasper PC4JB sends this update:

Dear radio amateurs,

We have made some changes to the webserver and the telemetry client to resolve some issues with the connection as stated before. It seems that the system is now improved, but we are not a 100% certain if it will be stable for long term. Unfortunately our resources and time are limited, so we have decided to go ahead with the systems as-is.

Attached is the new DUDe client, version 5.0. Please delete the previous version (4.7) in case you still have this on your computer. Thank you for your help and patience so far!

After orbit injection of Delfi-n3Xt, the satellite will first be idle for 25 minutes and then start deployment of about 5 minutes. The satellite will not transmit on the 145.870 MHz during eclipse, so the first time Delfi-n3Xt can theoretically be heard is about 8:38h UTC.

Attached are also the pre-launch TLE set which can be used in tracking programs. We will announce new TLEs on our website after launch as soon as they become available. After a few days, the satellite should appear in one of the regular automatically updated lists.

I am looking forward for a wonderful launch next Thursday, with many radio amateur satellites on board, and of course successful reception of Delfi-n3Xt!

73,

Dual-Band Slim Jim Antenna for Satellites

N9TAX Slim Jim mounted on top of the 3-meter mast

N9TAX Slim Jim mounted on top of the 3-meter mast

The AMSAT-SM website has an article on the dual-band omni-directional 145/435 MHz Slim Jim antenna developed by N9TAX.

Lars SM0TGU comments that the antenna works great for satellite passes below 30 degrees elevation, but signals are considerably weaker on high elevation passes.

A Dnepr Launch

A Dnepr Launch

An estimated 34 satellites carrying amateur radio payloads are expected to be deployed this week.

Four will deploy from the International Space Station on Tuesday and Wednesday, November 19/20, the rest in two separate launches.

The first launch, a Minotaur-1 rocket from Wallops Island Virginia, will be sometime after 00:30 UT, Wednesday, November 20, the other will be a Dnepr from Dombarovsky near Yasny at 07:10:11 UT on Thursday, November 21.

Join AMSAT-UK

AMSAT-UK_Bevelled_LogoFounded in 1975 AMSAT-UK is a voluntary organisation that supports the design and building of equipment for Amateur Radio Satellites.

AMSAT-UK initially produced a short bulletin called OSCAR News to give members advice on amateur satellite communications. Since those early days OSCAR News has grown in size and the print quality has improved beyond recognition. Today, OSCAR News is produced as a high-quality quarterly colour A4 magazine consisting of up to 40 pages of news, information and comment about amateur radio space communications.

The new lower-cost E-membership provides OSCAR News as a downloadable PDF file giving members the freedom to read it on their Tablets or Smartphones anytime, anyplace, anywhere.

An additional advantage is that the PDF should be available for download up to 2 weeks before the paper copy is posted.
