OZ7IT +3 in WSPR tropo 50.293MHz

Now I am the owner of the tiny Flex-1500 . This is not only a small transceiver but also a spectrum-analyser. I   have it running with WSPR   using  VAC  Virtual audio-cable ©  Eugene V. Muzychenko   and Virtual Serial Port  VSP Manager © Steve Nance K5FR  Only the  USB cable to the  PC   / Laptop is needed. Audio and serial port are virtual connections by software.   The 1500 has USB  no Fire-wire  this is a bit critical but with some tweaking in the configuration  I hope to get it stable over long time. Same way it can be connected to N1MM which I did not do yet. I was surprised  by its sensitivity at 50MHz.  A preamp gave no improvement on reception of the beacons. ON0SIX LX0SIX  OZ7IGY The Signal level meter is the best I have ever seen. Weak signals stil have a clear level reading 0-10db over the noise band. The Pan display shows all. I do have to read the manual there are many more options to find out. I let it run WSPR    Good signals from OZ7IT  +3dB
