WinRadio G305 covers 9kHz to 1800MHz. This has now become my favourite receiver as it allows easier and faster tuning and has a live spectrum display that assists a lot in discovering weak signals.
Initially I was concerned about the lower dynamic range and feared it might overload on beverages. However this turned out turned out to be no real problem, only images of very strong maritime signals could occasionally be noted at odd frequencies. Turning off the preamp helped a bit and slightly reducing the input signal with the pot of my phaser did the rest. Sensitivity was as good as the R390. Temporarily I used the R390A as a frontend for Winradio by feeding the R390A IF output (455kHz) to Winradios input to check if this would improve sensitivity or noise ratio, but I could not find any noticeable difference. Hence Winradios hardware is very good, but the software has some problems. Its audio filter doesn't work at all, they are simply useless. The S-meter does not show realistic values because it is affected by the strong adjacent channels. See below, on an empty 243 kHz channel it shows 65dBm, that's ridiculous. The same signal condition on an entire empty X-band would display -110 dBm. So far they have not fixed it, Winradios response on that has been lousy. Their response to users is very disappointing. Better don't expect anything in this matter.
Another very annoying behaviour in USB/LSB, below I expect to hear a 6,5kHz tone as audio. But instead I hear nothing. A tone becomes only audible below 4.5kHz. Above that everything is surpressed. All audio filters were turned off. That effectivley prevents you from monitoring a 10kHz audio range with a spectrum analyzer. I noticed this while monitoring TV carriers and was stunned that I did not hear the 6,5kHz that was show in the spectrum.
