Re: Feedback for version 1.0a here

Hi Steve, Compliments for the excellent work! I am already using it daily. One problem, though: I am unable to switch from RAW to AVG. The AVG mode never starts....Any suggestion? glovisol Averaging is only currently enabled at spans of less than 5MHz. I'm looking at ways of expanding this range. T...

Re: Feedback for version 1.0a here

Hello, I'm not able to go on 1000 MHz and over. I'm using a RSP1 and was able to go over 1000 MHz with the older version. What i'm doing wrong ? Thank you for your help. 73 QRO, Rudi, HB9ARI PS Seems to be related to an out of range index I have an RSP1 and I'll see if I can reproduce the problem. ...

Re: Feedback for version 1.0a here

I have found that it can take a lot of time for the peaks to calculate the frequency and db difference. I have seen it take over a minute. Is that normal? I running the software on an older laptop so that my be the problem. I just used the software to see what the harmonics look like on my dual LDM...

Re: Feedback for version 1.0a here

Steve I am struggling with the functionality of the markers. This is not as easy to use as the "cursors" were in your first release. Using the enable peaks functions helps, but sometimes I would just like to quickly point to the crest of a peak and put a marker there. Thanks again for all...

Re: Feedback for version 1.0a here

only suggestion would be the addition of "sweeps per second" display. this would help when fiddling with the step rate on the signal generator. attached are some return loss sweeps of a homebrew 222Mhz ground plane vertical on the "indoor range". It may be possible to add a &quo...

Re: Feedback for version 1.0a here

One feature that would be nice for a future release is a resolution bandwidth (RBW) annunciator. I'm not seeing the expected "processing loss" from none-blackmann.png windowing: Noise level for Blackman (yellow) is 1 dB above None (white) , expect 2.38 dB from the factor of 1.73 bandwidth...

Re: Feedback for version 1.0a here

I have one problem: I use windows 7 pro and your program loaded without problem and works great to the extent I can use it. However, the Control Panel does not load completely. Everything to the right of the word "frequency' is missing straight down the entire panel. Please tell me what I did ...

Re: Feedback for version 1.0a here

RSPduo: 1) spurts at 24MHz x n are so conspicuous compared to those observed with RSP1A and RSP2. Also, noise floor of RSPduo seems quite noisy. Is there any reason you can think of, or is this totally dependent on the RSPduo hardware? 2) As the default, the BC/FM and DAB are enabled although those...

Re: Feedback for version 1.0a here

Thank you Steve! This morning I did a quick test of the ability to measure harmonics using an Elecraft XG3 signal generator. The placement of the marks takes some getting used to. I found the fastest way was to enable peaks and then use the "next" buttons to place the marker on the peak t...

Re: Feedback for version 1.0a here

The behavior is quite stable if sweep is kept in bandpass range and no bandpass switching is neccesary. If sweep range need bandpass switching, it stops after some sweeps. This bug is showing up in various forms. I've noted it and it will be fixed for the release version. Thanks for providing addit...
