Best SDR approach

Flex 6500 and Mac Mini M2. To a potential new mac user, what software approach would you recommend to run this hardware setup. Any cautions that you would recommend be taken.

Tnx 73 Steve

    You will need Loopback, or some other audio connection tool to connect to whatever SDR software you use if you plan to use DAX on the radio. As to SDR software, you have two choices: dogparkSDR, or SSDR for Mac. TheSSDR for Mac is closest to the Windows SSDR, but dogparkSDR also works well.

    Mac and Flex radios make a good combination. That said, I still use Windows in a VM for those digital apps that just don’t work well on a Mac.

    And if you want a more sophisticated logbook, you have two options: paid MaxLoggerDX which works in conjunction with DogparkSDR (same very responsive author) and RUMlogNG (free) which works admirably well with the Flex6500 and whose contest part is very sufficient if you're not a very seasoned challenger.

    Like Ted I also keep the possibility of running a PC for some software like N1MM, CW Skimmer… and you can also run both computers at the same time, SmartSDR Mac on one side and WSJT on the PC (using CAT and DAX on the PC).

    For my part, I also use a Numark DJ2GO2 Midi interface with my Flex6500, which allows me to program the two VFOs for split pileups, left ear for DX, right ear for calling stations, so I can follow and anticipate where the DX station is listening. It's very effective!

    Unfortunately I cannot make this interface work on PC only on Mac with SmartSDR which guided my choice.

    I second Jean-Luc's endorsement of the Numark DJ2Go2. Works fabulously with SSDR Mac, and extremely flexible. Great job by Marcus.

    Thank you....I loaded dogspark to take advantage of the free trial. All loaded well but I couldn't get the radio and dogspark talking to each other. Couldn't open a slice. Is there anything in the mac setup that needs tweaking for this to work? Need to look for a users guide or maybe SSDR Mac may be more user friendly.

    I no longer routinely use dogparkSDR (I do use MacloggerDx), so can’t really hel pout, BUT there is a Google Group to support dogparkSDR - you may want to visit that. https://groups.google.com/g/dogparksdr

    Hi

    i am a long time mac and flex radio user...

    My current setup is Flex 6600m, and array for various mac running from Macbook Air M1, Mac Mini M1, as well as IOS devices, ipad pro , iPhone 14 and apple watch 4... also have multiple mac minis setup as a server farm that can connect to my 6600m across my home network...

    My recommendation are

    Macssdr from Marcus for over all sdr interface to the radio ( $$)

    as well as integrated digital modes and log

    Also Macssdr interface operations are very similar to Windows version SSDR...so going back and forth between mac and windows is very easy too

    as more robust and feature rich than dpsdr


    MACLoggerDX ( mldx) from Don ($$)...has builtin cluster with filters, award tracking to name a few features

    one of best mac loggers


    xDax and xCat from Mario for interface to various digital programs (freebee)

    Loopback for audio routing between apps ($$)...the one of best mac audio routing s/w

    these needed if running FT8 from WSJTX or JTDX


    WSJTX for FT8 operations (freebee)

    FLDIGI for RTTY other digital modes (freebee)

    JT-Bridge for aggregating multiple FT8 Streams ( freebee)

    yea...you can run more than one FT8 app simultaneously...i have done all 4 slices with the 6600m


    you may notice i did not show dogpark SDR... (dpsdr)

    it is good piece of ssdr s/w but there are nuances in the interface for me that at time confused me

    and

    from my experience, i believe Macssdr is better of the two based on ease of use and its full feature set.



    i will be glad to answer any question about flex radio and mac usage

    Paul pretty well covered it :-)

    Just watch out for interaction between xDax / xCat and SSDR for Mac. In fact watch out for interactions between MacLoggerDX and SSDR for Mac (probably only if you start up a second instance of SSDR on another Mac). I have had SSDR Mac not start up properly when other clients (DAX/CAT/Logger) were connected first to the radio. I expect you may not have these issues because you do not have a GUI on the radio, and will be using SSDR Mac for that. I have a 6600M and constantly run into this problem - Marcus had no solution.

    hi Ted

    SPOT ON...i have fallen into that trap...one time too many ;-)

    yep....have to start macssdr first...


    so for first time user, macssdr with mldx is best way to get started

    if that is good enough..great..if you want more there are more ways

    i am always experimenting...that is my lifetime adventure with hamradio and flex too

    Jean, Ted, Paul......thank you for your advice and suggestions. I think we'll give SSDR for Mac a try today.

    SmartSDR for the Mac is the best. Marcus designed feature rich work of art.

    Thanks Dan......I bought SSDR for mac and have it installed. Now I need to live with it for a while to find out where everything is located but the good news is it's working.

    My biggest issue for now is: what mouse are you guys using? I tried a magic mouse and I don't like it......tried a logitech m510 it's better but in mac ssdr is there a setting for freq. steps when you spin the thumbwheel (been looking but no luck yet) sometimes I need to click 2 to 4 times before things happen. Also the thumbwheel works in the opposite direction from win11.

    This is probably not the right place to be asking these questions.....time to read the manual!!!

    hi steve

    in settings you can set mouse wheel direction...

    just set it to reverse...

    Paul K3SF


    Oh..i use logitech mouse on the mac mini and the trackpad on my macbook air

  • Dan Trainor

    Steve, I use Magic Mouse, so don't have a feel for others. But, in SmartSDR=>Preferences=>Mouse/Trackpad dialog box there is options for Enable Mouse Wheel, Legacy Mouse Support, Reverse, Swap X/Y and Sensitivty Now on changing freq and freq steps... I found the easiest way is to turn on slice details: View=>Slice Details or alternatively click on the slice flag with mouse. Now, A Slice Details dialog box will appear. There are many useful things you can do in this dialog box, but related to changing freq and freq steps. Click on STEP and change to your preferred step value. I use 500 for USB/LSB mode. Above the you will see the Freq displayed and arrow symbols for stepping up or down in freq. Try these, they are quite useful for stepping up and down a band. (Everything in this Slice Details box is useful, go through all and try all) On freq change, of course, you can always double click on panadapter screen to change slice frequency. Also, set BW (vertical menu on left) something like 50 or 75 - it zooms in and makes it easier to see Slice signals and helps when changing freq. Hope that helps. If you have any other questions, fire away.... Dan de WA1QZX

    hi steve


    even i forgot about how to do step size...it is a pull down menu in slice panel

    Steve, for latest manual click on Help=>SmartSDR Help and that will fire up a Safari browser tab at this URL: https://documents.roskosch.de/smartsdr-mac/

    It is very well written and up to date.

    I use a Kensington trackball and a DJ2Go2 with SSDR Mac - both work great. I generally use the arrow keys to finely adjust frequency, setting the step size as needed - I usually use 100 Hz with snap to step.
