Re: [Flexradio] Is this computer sufficent?
Mine does not show a true waveform of the TX AM signal. It does not show modulation in the negative direction. it shows the carrier on TX, and the positive modulation. I don't need any sort of sync setup, I have a scope on the IF of the homebrew receiver and it shows a nice waveform on transmit and receive, without any sync. I was told the display in the flex uses the receiver to monitor the transmit signal. What I would like the flex to do is to do what the scope and homebrew receiver do, show an accurate display of the AM modulation.

Re: [Flexradio] Is this computer sufficent?
On AM, the scope is useless as it only shows the audio waveform. In the shack, its handy to have an Oscope to look at the transmitted waveform (to make sure the modulation looks good) and the received waveform to see what the other peoples modulation looks like. Lots of AM operators use homebrew (me) radios, or vintage radios, and like to check things out to make sure things are set right. On receive and transmit, we want to see the modulated carrier, the audio waveform is useless. On both TX and RX, the scope shows nothing that is useful. On RX, it shows no carrier, on TX it shows the carrier but not the negative modulation... Also, there is no IF output to hook a scope up to. I hear a LOT of flex radios on AM, they sound very good and have lots of nice options, but have 2 major bugs, the scope and the auto notch filter which 'seems' to notch out the carrier, not the interference. I am not sure if its set to notch out the strongest steady signal (which is the carrier on AM) or if something else is going on. The Icom 756 pro 3 I had worked great in that respect.
