There’s a new radio hobby magazine in town!

Recently, a number of hobby radio magazines have either retired, or have merged into a digital mix of several. Filling that void is the new The Spectrum Monitor, a creation of Ken Reitz KS4ZR, managing editor for Monitoring Times since 2012, features editor since 2009, columnist and feature writer for the MT magazine since 1988. Ken offers this digital, radio communications magazine monthly.  The web site is at http://www.thespectrummonitor.com/

Messages from space

Messages decoded from the FUNcube-1 satellite

FUN cubed

I have just received my first telemetry from the FUNcube satellite, a.k.a. OSCAR 73. It was a piece of cake, one of the easiest things in ham radio I have done. What helped make it easy was that I was using a FUNcube Dongle Pro as the receiver (thanks, John!) . The FUNcube dashboard software supports it out of the box. No drivers to install or soundcards to configure. It was a piece of cake.The Dongle automatically tunes to the right frequency.

Of course, the whole project has been designed to be used by teachers with no previous experience of this kind of stuff. So you would expect it to be easy for a seasoned radio ham!

The FUNcube Dashboard software

The whole thing went something like this:

  1. Download and install .NET Framework 4.0 from Microsoft.
  2. Download and install FUNcube Dashboard from http://data.funcube.org.uk/
  3. Register your call at the FUNcube data warehouse https://warehouse.funcube.org.uk/.
  4. Download, read and follow the instructions (PDF files) from the FUNcube site.
  5. Connect dual band colinear to FUNcube Dongle.

Sit back and wait for a pass.

 I was not present when the satellite went over as I was downstairs having lunch.

There are no suitable passes over this location this evening or tonight so I will have to wait until tomorrow for another try. Unfortunately apart from an FT-817 and the dual band vertical I don’t have equipment that can operate 2m ans 70cm so I’ll have to leave tryi ng to work through the transponder to someone else.

FUNcube Dongle – sold out in 49 seconds

The latest batch of 135 of Howard Long G6LVB’s FUNcube Dongle Pros sold out a few hours ago in less than a minute!

The FUNcube Dongle Pro is a tiny SDR receiver for the frequency range 64 to 1,700MHz. It’s the “ground segment” of the AMSAT-UK FUNcube satellite project.

The best source of information about what to do with the FUNcube dongle and how to get hold of one is the Yahoogroup. Howard is active on the list and the main website and is quick to join the discussion and respond to all manner of queries.

The FUNcube Yahoogroup page explains the background and aim to the project:

AMSAT-UK’s FUNcube is an educational single cubesat project with the goal of enthusing and educating young people about radio, space, physics and electronics.

It will support the educational Science, Technology, Engineering and Maths (STEM) initiatives and provide an additional resource for the GB4FUN Mobile Communications Centre.

The target audience consists of primary and secondary school pupils and FUNcube will feature a 145 MHz telemetry beacon that will provide a strong signal for the pupils to receive.

… FUNcube will carry a UHF to VHF linear transponder that will have up to 1 watt and which can be used by Radio Amateurs worldwide for SSB and CW communications.
Measuring just 10 x 10 x 10 cm, and with a mass of less than 1kg, it will be the smallest ever satellite to carry a linear transponder and the choice of frequencies will enable Radio Amateurs to use their existing VO-52, DO-64, HO68 and similar stations.

Howard seems to be producing and selling the Dongles at an amazing rate. But on the basis of this recent post “What do 500 dongles look like?“ there are at least another 360-odd on the production line.

NASA seeks help tracking satellite

NASA has asked amateur radio operators for help to determine if a recently launched satellite is operating. The NanoSail-D satellite was ejected automatically from the Fast Affordable Scientific and Technology Satellite, FASTSAT on Wednesday, January 19. NASA needs reports of the beacon telemetry to determine if it is operating correctly. The beacon signal is on 437.270MHz using standard AX.25 packet so APRS and packet radio operators with 70cm capability should be able to receive it.

Predictions for the satellite can be found here. Reception reports can be submitted here. Full text of the NASA press release here.

Work FM Satellites

I came across this website while reading a thread about the new Kenwood TH-D72. It claims to be the best website for current information about working FM satellites. It looks pretty good, but I really need to find the time to look through all the information. There’s a blog, too.

The trouble with this hobby is that there is so little time and so many interesting, challenging things you can do!

ISS success

Over the last few days Lynn, KJ4ERJ has been adding some very cool features to APRSISCE/32 which I’ve been helping to test. The ISS packet digipeater is still operating so as there were several good passes during the daytime I’ve been playing on it as well.

Today I managed to hear my own beacon repeated back by the space station, and this time it was also gated to the internet by TF8TTY so my call showed up on the map of stations heard through the ISS at ariss.net. I also managed to send a couple of messages through the bird. Tim, G4VXE was impressed to receive a greeting relayed via the space station. I also managed a two-way exchange with Marc, PD4U, which I think counts as an actual satellite contact.

Of course, whilst it’s fun to bounce radio waves off a satellite it isn’t a very practical method of communication. The ISS is the best QTH ever and it can hear all the activity on a frequency at the same time, so communication is only possible if not too many people use it. Lots of messages never get anywhere because they are sent at the same time as messages from other people which you can’t avoid transmitting over because you can’t hear them. The space station decodes only the strongest, so turning the power up improves your chances of success quite a bit. You can get through the ISS using a hand-held VX-8, but only at 4 o’clock in the morning when most sane people are asleep, unless you are incredibly lucky.

The new feature in APRSISCE that I mentioned is the ability to open separate windows so you can track individual stations at a more detailed mapping level. Lynn has called this Multi-Track(TM) and he thinks it will be very popular with emergency communications teams who will be able to see the entire area of the event in the main window and see exactly where individual team members are at the same time. It’s only available in the development (beta test) versions at the moment, though.
