[Flexradio] PA Duty Cycle

I know the maximum continuous power output is 40 watts. What is the duty cycle (and period) at 100 watts? Is airflow the limiting factor or is there another issue? I just read recently (EDN magazine?) that air blown directly at a heat sink, rather than across it, provides more effective

I've spent a lot of my life in HVAC. It is difficult for me to accept the idea that air should be blown against a (I assume finned and not some simple plate) heat sink for maximum efficiency! Lee K9WRU - Original Message - From: John Spangler [EMAIL PROTECTED] To:

The manual notch filter is important. All of the programming effort for the past few months has been towards getting the FLEX-5000 working with PowerSDR and not on providing new features. Enhancements and new features will get put back on the programming to do list once support for the FLEX-5000

Re: [Flexradio] Manual notch filter?

Re: [Flexradio] Manual notch filter?

Guy, Of course, a notch filter could be coded to work anywhere in the range of the panadapter display. However, don't hold your breath waiting for it to do what you want. If the splatter is caused by an improperly adjusted transmitter somewhere else on the band, then the splatter consists of

Hi Ray, Point well taken. I shouldn't have described what I had in mind as splatter. Over modulation would probably be more correct. I DX foreign medium wave stations from Asia and the Pacific, and the #1 reason this type of DXing is a big challenge is due to the wide signals from domestic
