STELLA Linear Transponder DSP IF, plus LVB Tracker 2 info

Folks

I have put some further information (mostly pics) on line about the auto-notching DSP linear transponder IF I ve developed in conjunction with David G0MRF s RF expertise, presented and demonstrated at the AMSAT-UK Colloquium this last weekend.

After spending the past six months struggling to make time to make this and the LVB Tracker 2 demonstrable projects, life would be quiet. From the extraordinary response I have received it seems that this will not be the case…

The technologies popularised by Gerald Youngblood s SDR-1000, and used extensively by the STELLA device, I am sure will go from strength to strength.

Trevor M5AKA meddelar via mailinglistan att ISS ny kr med crossbandsrepeatern:

The International Space Station cross-band or U/V FM voice repeater has been switched on.

The downlink is 145.800 FM +/- 3 kHz doppler shift
The uplink is 437.800 FM +/- 10 kHz doppler shift

Please keep in mind that the crew members John and Sergei may be listening and pick up the mic to talk to you.

The ISS repeater can be worked with very simple equipment. To receive it on 145.800 an FM handheld with a 1/4 wave whip is all that s required. On 70cm you need to be able to transmit at least 2 or 3 watts FM into a 1/4 wave whip.
