Yeah, depends on your point of view. It makes me happy as a mediumwave DXer. As a ham whose small antenna works best on the high bands; not so happy. 73 - Ken Sent from my BlackBerry device on the Rogers Wireless Network -Original Message- From: Tony Estep Sender: flexradio-boun...@

[Flexradio] Remote power control for flex 5000

2012-02-21 Thread Greg Evans
Is there a way to have the radio to where I can command it to turn on remotely? I need to be able to turn the radio on or off from remote locations. I am not referring to starting the radio, but to powering it on so that the computer sees the Flex... Thanks, Greg Evans K5GTX __

That helps. You are likely going to have to do a lot of work on this by your self. Since you want to have the audio go to the SCS Modem, you will have to manually either wire it to the speaker output to the modem, and the also wire the transmit audio back in through a mic connection. The same fo

I'm pretty sure this is covered in the Flex knowledge base. You have to set up the port(s) under the DSP menu in Power SDR. While this is for Writelog http://kc.flexradio.com/KnowledgebaseArticle50366.aspx The settings are similar for dx4win. The Flex settings will be the same. The concepts a

Hi All, I'm not sure what kind of parameters you'd like to be able to adjust Brian.  I think that if you put a good filter at the antenna jack and get rid of the AM broadcasters then your Flex can easily do the rest. I have already built a lowpass filter that cleans the longwave band of any A

Brian, Yes I agree about your assessment on the preselector, but who is going to take the time to design, test and market the preselector. We could talk all day what it should be in theory, but until someone takes the time to take their theory and make it a viable product all we have is " what

I agree a bandpass filter makes sense for just 472-479 kHz. My low-pass filter was intended for receiving the entire LF range. Carol, KP4MD/W6 On Tue, Feb 21, 2012 at 8:25 AM, Brian Lloyd wrote: > > > On Mon, Feb 20, 2012 at 10:56 AM, Carol F. Milazzo, KP4MD/W6 < > kp...@cfmilazzo.com> wrote:
