I would prefer to avoid Microsoft Surfaces as they appear to be "rather
overpriced". I have searched in the group for tablet information and found some
threads that are older but nothing really current. It would be used for this
dedicated purpose and as such would not need to run any other software
concurrently. I'm hoping something with 4 or 6 GB of RAM will be sufficient. I
see them on Amazon in the mid $200 range.
I have one of these:

CHIWI Hi10 XR
2 in 1 Laptop with Stylus Pen, 10.1 Inch Touch Screen Tablet Pc,
6GB LPDDR4X 128G SSD, Turbo frequency 2.6GHz, 1920x1200 Resolution

which is a separate tablet and keyboard. The touchpad isn't all that good as
the reviews say, and I've not actually used it in tablet-only mode. It has
updated successfully to Win-11.

I guess you get what you pay for!

I suggest *always* using a cubic spline to find the local peak value when looking for the peak in an array of bins.

Well if they aren't centered I'd think that could be fixed by tweaking the LO freq.


That is the LAST thing I want to do. It is what I have to do with SDRC.

Why might you be logging peaks rather than power.
I'd like to record total channel power like HDSDR does, but peak power is all the SNR logger plugin will do.  Since one application is simply to compare signal strength over time, peak vs. total doesn't matter so long as it's consistent.

Bob NO6B 

It sounds like the SNR plugin is as broken as I expected. Good luck with it. I don't think your FFT approach will solve the issue properly; but, I could be wrong.

I have the FFT resolution set to 512, which is the lowest it can be set to.  The only way to get the FFT bin size large enough to adequately capture a NBFM signal is to disable decimation, which leaves me with only 12 bits of dynamic range.  In the crowded SoCal VHF/UHF RF environment I often find that I need a couple more bits of resolution to maintain decent sensitivity without occasional overloading, so I prefer to use a decimation of 16 or 32.  I could still effectively log NBFM channel power if I could further reduce the FFT resolution to, say 16.  At a decimation of 32, the bin size would be then 150 kHz / 16 = 9.38 kHz, just enough.  The FFT display would be kind of useless, but it would allow using the SNR logger to record channel power of wider emissions like NBFM, & my guess is that this would be very easy to implement since fewer resources would be needed to implement a smaller FFT.

locked Windows 10 Tablet Recommendations? #win10

Scott/KC1UA
 

Good morning,

Backstory: I have three portable SDR's. An authentic Malahit, a new Airinst SDR Dreamkit, and a very reliable Afedri LAN-IQ. While all are very nice in their own way, I find them lacking with regards to things I like to be able to do while portable and searching for signals. My primary interest is searching from 30 MHz and higher. 

Intent: I would like to run SDR# and an Airspy Mini as a portable setup. I would also really like to be able to cram DSD+ FL in there as well, along with a few of the more popular SDR# plug-ins such as the CTCSS and DCS decoders, and the frequency scanner. 

In search of: Current or recent Windows 10 tablet that will support the above. I would prefer to avoid Microsoft Surfaces as they appear to be "rather overpriced". I have searched in the group for tablet information and found some threads that are older but nothing really current. It would be used for this dedicated purpose and as such would not need to run any other software concurrently. I'm hoping something with 4 or 6 GB of RAM will be sufficient. I see them on Amazon in the mid $200 range.

Other stuff: I'm interested in any feedback with running SDR# from a touch screen and experiences good or bad with that. I'd likely look for a tablet with 2 standard USB ports and use a mouse. Also, I expect some interference issues given the proximity of antennas to the tablet. Are there any tablets that anyone has found to be less of an interference source, and/or how have you overcome or minimized any interference other than getting your antenna as far away from the laptop as possible; not always possible when portable.

Many thanks in advance for any assistance.

Maybe it's the same problem I had.  My Avast antivirus program wasn't allowing downloads from a particular web site.  I placed the url of the site in the exception list and that fixed it.  In Avast: Menu (upper right corner) >Settings >Exceptions >Add Advanced Exceptions >Website/Domain and then type or paste the url into the entry box.

I can't tell for v1830 and the DCS decoder, but CTCSS plugin (by "the wraith2008") runs smoothly with v1827.
