Re: Continuum mode
Great news, Simon, and glad that Moe was able to help. He must havea better memory, or more organized files than I ever had.
It would be wonderful if you could document the algorithm that you willuse

So,
Spoke with Moe, I now know all I must do when I restart programming.

Re: shipping update from Apache regarding the Hermes
Hi Conrad,
Thanks for sharing that. I also have one on order. Some rumors have been circulating around hinting that it might be delayed. I am sure they will get it figured out.

Re: K4 and SDR-Console
Conrad,
Thank you
I figured this question would come up.
The K4 does have a beautiful display and I do use it.
I have a video capture card and route the HDMI port on the K4 to my PC and then can use

shipping update from Apache regarding the Hermes
I received this from Apache regarding shipment of the 14-bit Hermes that several users are waiting for.

Re: K4 and SDR-Console
Hello Fred.
I must ask why you use an RSP2Pro and SDRC when you already have an SDR based radio with a waterfall? Surely the K4 has a much better receiver. Is the K4 waterfall poor?
I use SDRC

K4 and SDR-Console
Anyone using the Elecraft K4 with SDR-Consloe?
I'm have a small problem.
When I have SDR-Console running then I start the K4 up it puts the K4 into transmit for a few seconds.

Re: Continuum mode
That would be my understanding also, and easy to test inSpectraVue.
I've just played back a NetSDR file in Continuum mode, 1300kHz span ofthe MW band, using 2048 point FFT and 2097152 point

Re: Continuum mode
I wouldn't think that the RBW matters for this. Just sum all X bins. If RBW is smaller then X will be bigger and there will be less power in each bin. Sum of the bins will be the same for a given

Figure one signal is present, a unit gain (0 dBfs) sinewave. Without shaping it will appear in one or two bins ideally. You take the power level for all bins within the bandwidth Y and

Re: Continuum mode
Typo.
Given:
Center frequency & bandwidth with have a count of FFT bins = X (values in dBm)
Resolution bandwidth = Y Hz
What’s the formula for the actual continuum value when these X bins

Hello Simon, I really appreciate you adding this feature. I do have SpectraVue and an SDR-IP and in the past like Charles I used SDRC with Perseus and the IQ outputs as inputs for SpectraVue. Very

Re: Continuum mode
Heh heh - processing in the frequency domain makes a lot of this easy. The chief issue is the current FFT resolution compared the bandwidth you want. The "cheap, quick, and dirty"

Re: Continuum mode
Hi.
I would like to add two more points to the short spec for the Continuum Mode function:
Possibility to set a smaller BW for the measurement than the sampled BW and to set where this BW shall be in

Not at all.
Glad you found the positive saying!
The one I came to think about mirrors the Scandinavian "Jantelagen" and misery and gloom.
Raising a finger of warning, do not indulge!

For satellite use, I find Mercator projection helpful ("round" footprints).
Perhaps something for the future?
