  1. I recently purchased your book for Radio Amateurs and decided to install Motioneye. All went well until the login invitation was seen. I failed to make progress so last week I bought your pre-loaded version of Motioneye for a Pi3. No matter what I input, IP address, user, pi or even the password for my BT Router, the software rejects all. What is the correct ‘login’ please?

    1. Hi Eric,
      Apologies for the slow response. You don’t need to log in to the Pi at all as it will only give you a command line prompt. To see the main program interface and controls you access MotioneyeOS through a web browser using your Pi IP address. You can use any computer on your local network to do this. Once you get to the web page you can login with admin and no password.



  2. Hi Mike,

    I have purchased your book “Raspberry Pi explained for Radio Amateurs”
    I wonder if you have any images for sale which include a means for automated wxsat reception.
    I have installed WXTOIMG and have it decoding using Cubic SDR and an Airspy Dongle but I have to manually change the frequencies. I have installed SOCAT and created a pair of /dev/tty ports as per your book. Cubic SDR can see the ports but WXTOIMG cannot so I can’t get it to work.
    Wonder if you can help?

    1. Hi Mike, Thanks for buying my book, I hope you find it useful. I haven’t tried what you’re attempting but I’ll have a go next week and see if I can help. Regards, Mike – G4WNC

  3. Hi Mike,

    We have a card from you works great. My friend radio amateur did something wrong and from our original card all frequencies in JTDX are missing. can you give me an idee how to get it back ( or perhaps a new download ?? His call is PA0JCA he bought it by you from Aalsmeer, my call is PE1BSB. and i have a copy. Regards William

    1. Hi William – I’ve replied directly to your email. Mike

  4. Hi Mike,
    Sorry to be a pain but I cannot find the front and rear panel .pdf’s for the nano Keyer. Can you advise me where they are please? I have looked over your site!

    1. Hi Gwyn,

      Apologies for the inconvenience. I’ve been out of the country and forgot to post it before I left. You can find the info here

  5. Hi Mike

    I recently bought the data-modes SD, initially to use with the PI zero. however as it has taken so long for the Zero to come into stock I upgraded and have just had the 4B delivered.
    Software works fine, but being “old school” Id like to connect an old valve rig (FT200 or FR101) to “listen” for FT8 transmissions.
    Do you cover external I/O connections between pre digital rigs and the PI family anywhere?
    TIA Glenn

    1. Hi Glenn,

      Thanks for buying one of my cards. The Pi should work fine with an old valve rig, but with a few precautions. The audio side is straightforward as, for receive only, you just need a single screened lead to link between the Microphone input on your USB soundcard and the audio output on your rig. I don’t think The FT200 or FR101 have line-level audio outputs, so you will need to tap the audio from the headphone or speaker output. You might find it helpful to add a 10k potentiometer in this lead so you can set the correct audio level into the Pi.
      If you want to use rig control (assuming those rigs support it) you need to be careful with the interface voltages. Many older rigs use 12V signalling on the RS-232 port, whereas most modern USB to serial adapters work on 5V or 3.3V signalling. If you want a ready-built interface, the excellent DigiRig unit is available with 12V signalling.

      Hope that helps,

      1. Thanks for the info Mike,

        Will let you know how I get on..!


        1. Hi Mike, I’ve had some time to play with the PI and data modes, most impressed so far with the FT8 rx only app!, especially when running from a kenwood handy with HF rx!. Next question is if the inbuilt software can be used to run WSPR from the PI as is, or do i need a specific app to do this?

          1. Hi Glenn,

            Yes, the WSPR mode is part of the WSJT-X suite so it will work fine with the Pi.

  6. Hi Mike,
    I recently bought your Spyserver SD card and installed it on a Pi4B. With a RTL dongle the server worked fine remotely from SDR #. When I tried it with my Airspy Discovery/HF Dual port I get the errror message “Server busy” when I try to connect from SDR #. I use latest version of SDR#. Any idea of whats the problem?
    Best regards SM7FQX Ulf

    1. Hi Ulf,

      Sorry to hear you’re having problems. Spy Server and SDR # tend to get confused when you change receivers. Try the following sequence and let me know how you get on.
      power off the PI
      Exit SDR #

      Power-on the Pi
      When it’s finished booting Open SDR# and try and connect.
