Minimizing CPU load
I've been trying out Ham Radio Deluxe Logbook recently and noticed it can be quite sluggish. Traced the problem down to SDR Console itself. It seems like running SDR Console is enough significantly

Re: Continuum mode
If sampled with 2. 688 in pluto also downscale to anything smaller
Be it 500 kc (transponder bw)
Down to 1hz (or calculated /referenced down to that fine resolution)
Could be very useful to measure

Re: Continuum mode
Hi.
I took the liberty to collect the specification points we have been throwing around here in this thread for a week or so, in one bulleted list.
I hope it makes it easier to have all of them in one

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

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

Re: Continuum mode
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
