When one channel is running DRM today's v1.367 release allows the other channels to connect (audio and waterfall), with the limitation that they cannot use any extensions. This is because the Beagle cpu processing requirements of most extensions might be beyond the point needed to support DRM. This condition might be relaxed in the future as more improvements to the DRM code efficiency is made.

You can limit the number of non-DRM channels allowed to connect with a new setting available on the DRM sidebar of the admin "extensions" tab.

The code to detect and enforce these conditions was tricky to write and it is quite likely that there are problems remaining.

From the CHANGE_LOG file:

v1.365,366,367  January 10, 2020
    Decouple kiwisdr.com/public and sdr.hu registration.
        Can register on either or both.
        Rename admin page tab "sdr.hu" to "Public".
        API key only applies to sdr.hu
    Allow limited regular connections when DRM active.
    Build DRM files only when needed.
    Consider local timezone when scheduling updates (i.e. 1AM - 6AM local, not UTC).
    Log build messages to /root/build.log file to aid in build failure determination.
    Improve web server caching (more closely follow web caching standards).
    More protection against users making invisible connections and other hacks.

Yes, in the next release the DRM button will be properly disabled (greyed-out) when DRM is disabled.

Yes, SAM (synchronous AM) is a placeholder. I figured people were going to be upset enough when I changed the mode buttons (they were) that I better only do it once. Even if it meant using placeholder(s) for anticipated future changes. Depending on your browser if you hover over SAM a tooltip should say "not yet implemented".

Do not despair about Dream/DRM -- Santa's elves have been busy:

Selecting 'DRM' in the mode menu of the DX tag is what's broken (and I've just fixed for today's update).

In some respects the DRM extension has just caused a huge drop in the number of available public Kiwi channels. This is one reason I'm always preaching that we need more public Kiwis made available even though looking at the map it seems we have plenty.

But it is early days yet. I am working on improving the efficiency of the code. In recent tests I am able to run one DRM plus 3 ordinary connections provided they don't do anything harsh like run the WSPR extension.

And there is also hope that eventually two active DRM sessions will be able to run on a stock BBG/B Kiwi.

v1.362 fixes a few memory leaks and crashes and makes some minor user interface improvements.
As with other extensions you can make a bookmark that selects DRM and an existing station in the menu, e.g.

my_kiwi.com:8073/?ext=drm,3965        (brings up RFI on 3965 kHz)

The cached build mechanism is still not working, so this update will take around 35 minutes.
