FUNCube-1 a thank you received from space!
I posted a few weeks ago about issues I and others were having decoding the telemetry from FUNCube-1. Initially this seemed to be related to a dashboard software update, but even downgrading to an earlier version has been giving variable results.
What seems to have been the issue is a reduced quality of received signal. Operators with higher gain, optimised antennas appear not to have seen problems. Why there has been such a fall off isn't clear, the power output of FUNCube-1 hasn't altered and appears not to be tumbling.
The FUNCube team have now released a new version of the Dashboard Software. Version 820 can be downloaded from http://funcube.org.uk/working-documents/funcube-telemetry-dashboard/ The major change in Version v820 centres on improved decoding routines which give better results, especially with weak signals at low elevations and simpler antennas.
I have been running this now for several days and can confirm it is much better, as promised low elevation passes now get successful decodes and night time passes when the telemetry is on low power get successful decodes something I wasn't getting before.
Now I have the shack sorted I have set up a dedicated receiver using the original FUNCube Dongle using the X-30 white stick collinear and this has been pulling in decodes nicely.
This morning I had surpassed the 2000 telemetry decodes milestone, as can be seen on the rankings page.
Another nice result over the weekend was seeing my callsign in one of the FITTER messages
The next stage for me? Well must sort out trying to have a QSO via FUNCube-1 and the other satellites..

Rx'd my callsign in the 'Thank You' Fitter messages from FUNCube-1 over the weekend, nice touch! pic.twitter.com/MvJt8p6tVUIt is a nice touch that the FUNCube-1 have started acknowledging the receivers, hopefully with the improved software there will be more participants.
