    You can adjust the equaliser if you leave it turned off, set it and then turn it on.
    I tried QUISK it runs but crashes and I cant get the screen size right. It has no config screens which is a right pain.
    I loaded a DX cluster program called Xdx it works fine.

    Now that I have piHPSDR running I wondered what else I could get to run on the same hardware. This caused a great deal of heartache and wasted time. I wondered if I could get my Funcube Dongle to work and the quick answer is No. qthid will not work (on a pi or on the ASUS board). gqrx worked once only but now will not work. I have uninstalled and reinstalled it but it fails every time. SDR# will work under Mono but not very well and the screens are too big. The qthid-fcd variant will not work, but the command line version fcd-ctl does work. Unfortunately it is just command lines and way too tedious for real operation of the FCD.

    However FLdigi will work and can be made to control the FCD pro+. Also Gnome Predict which is a satellite prediction program works pretty well although the aspect ratio of the display is a bit stretched.
    I am looking for other stuff that works with the 7 inch screen.

    TOP TIP a lot of config screens are too big for the screen and you cant get to the OK / Save buttons. Try holding the Alt key down while you move the window with left mouse button held down. It allows you to get to the buttons.

    The piHPSDR kit arrived from Apache Labs. It is really well made. You get all the screws and even the Allen key for fastening the knobs which are metal and really nice quality as well. You will need a larger Allen key and a Jeweller's screwdriver to assemble everything. I got it all together in less than an hour. You have to solder 5 wires on the power cable between the video control board and the mainboard. The instructions say to remove the header strip, but I didn't bother. If you really don't want to solder you could get a cable with connectors on both ends and avoid soldering completely.

    It works!!!!! Even with 384kHz sample rate and I don't have the low voltage indicator on the screen anymore. Trying to adjust the Equaliser still instantly crashes the program, but I'm sure that the next release will fix it.

    My right two push buttons don't feel right, they are not as 'clicky' as the others so something must be binding somewhere. I will have to open up the case, but I'm sure it will be just a matter of adjusting the mounting screws. [Yep all fixed now]

  • Great videos, the noise cancelling one is amazing. For some hams it could make a huge difference to the enjoyment of the hobby.

    Yipee the ASUS Tinker Board arrived today. Bit if a challenge making it go. You have to follow the instructions VERY carefully. I had a problem with running the build on the GPIO package (this is not required for a RPi 3). The build command failed. It is something to do with library paths. I sorted it out eventually more by good luck than good skills. So it works, except for the Equaliser. I believe I saw something somewhere that said that it isn't working yet. On my system, attempting to adjust the EQ crashes the program back to the Linux desktop. But the noise reduction works (sort of. It isn't very nice though). And I can run the 192 kHz sample rate. Running 384 kHz crashes everything back to boot, but I believe this is due to not having a good enough power supply, because the screen goes funny fading in and out. The audio sounds good.
    I ordered the kit from Apache Labs, so that will be the next step.

    The Raspberry Pi 2B wont run the noise reduction filters either. Not all that surprising since the code is really for the much more powerful RPi 3.
    Wish list. I really wish it had a mute button. I may have to investigate the source code and see if I can compile it. I'm not sure if I can use Visual Studio for Windows to write Linux apps. Zoom-able panadapters would be nice. But overall the software is really excellent. It provides essentially a subset of the PC application so there has to be compromises.
    There are spare buttons. It would be great if they could be user defined.
    And I would like to be able to change the preset filters. Even if only by changing the 'props' file. The config file seems to allow changes to the variable filters, but not the presets.

    Oh yes definitely. All kinds of SDR are of interest ;-)

    The Tinker board has not arrived yet. It is not due until the 16th. But the screen arrived and I already had a Raspberry Pi 2B. So I made the screen work by following instructions on the web. I ended up loading the latest version of Raspbian Jessie. Initially the screen would display the boot sequence but crash before the Linux GUI screen came up. After much tribulations including the update of Linux, which turned out to unnecessary, I found out that what the forums all say about you needing a 2Amp power supply was true! My 700mA phone charger is not enough! I am now using a USB cable off my main PC and it all works, although the display is showing a low voltage error (lightning bolt) symbol. Note that the PiHPSDR controller has a 13 Volt to 5 Volt voltage regulator so you just use your station 13.8 volt supply.
    Following the instructions in the piHPSDR installation guide (not the users guide), I successfully installed the piHPSDR software and it works very well. What an excellent piece of software!! It looks great.

    A couple of notes.
    1. I had changed the font size for menu items in Linux to make them easier to read on the 7" screen. This was a mistake and caused the function button and slider controls in piHPSDR to disappear off the right side of the screen. Setting the font back to default 12 point fixed that.

    2. The Raspberry Pi 2 will run the application fine even with two panadapters BUT DO NOT attempt to use a sample rate higher than 96,000. It will crash the application and it is quite difficult to get it to run long enough to change back. I'm sure higher sample rates will be fine with the Raspberry Pi 3 and the Tinker board which are much more powerful. If you do have this problem and you cant fix it within the menu system. There is a file in the piHPSDR directory which is titled with the MAC address of your radio . props. Fixing the line receiver.0.sample_rate=96000 should fix the problem.

  • Now that is going to be interesting. You are probably the only person in the world to own / have owned an ANAN-100D, an MB1 and a Flex-6500. You are probably uniquely qualified to compare the features and usability of all three radios. P.S. I now have MB1 and Flex-6500 envy. :-)
