NOTE 2 If you use a tablet or mobile phone, try this one: ==> Mobile version <==
We are also listed at PocketRxTX thanks to Dan YO3GGX: ==> PocketRxTx Screenshots on Android <==

NOTE 4 Antenna is normally Inverted-L (54m longwire) but can also be a MiniWhip or G5RV (2x17m), depends on the bands I'm using myself.

NOTE 5 Typical bands below 10MHz use LSB and bands above 10MHz USB, however, 60M uses USB as well as most professional users like coastguard and aircontrol.

NOTE 6 The very best radio-station of Belgium is JoeFM (dutch but continues music at night), direct stream: ==> JoeFM <==


News:
30/03/2018 - We have replaced the motherboard and CPU and added 2 more dongles and testing a whole set of new driver parameters.
31/03/2018 - We had to remove bands because the new CPU still overloaded and they where not used much.
07/04/2018 - Replaced old fan-less Celeron 847 back, installed RealTime Linux-Kernel, seems to have solved all problems.
26/05/2018 - All Dongles back behind upconverters, they got overloaded in the evening.
