In the last few weeks I have not done too much with the SunSDR except make a few hundred QSOs. This is fun!
The only real thing I changed was to print 2 brackets on the 3d printer to mount an 8 cm fan above the transceiver. For now I have this 12v fan running from the same 15v supply as the transceiver but I put 8 diodes in series to get the voltage for the fan down to about 6v. The fan runs very quiet and the max temp I have seen in ExpertSDR since I use the fan is 30°C while making QSOs in JT65.
If you want to print your own brackets, please let me know, I’ll send you the STL-file. Or for those living nearby I can print them for you.
Hi Jurgen,
Nice project, it’s exactly what I was looking for 🙂 If you could please send me the STL file. Thanks.
Unfortunately WordPress does not allow me to upload STL or Zip files. I sent you the file via email.
