Support for Morse Micro 900 MHz Halow node
Orv indicated that this will be supported on the new babel nightly build. Does it need to be flashed, and i so where is the software?

Yes, firmware is available
Select the Babel only build for the Morse Micro Halowlink1 from the repository.
Upload the firmware to the Halowlink1 and remember to UNCHECK the Keep Settings box.
Everything else proceeds as with any other AREDN sysupgrade.

OK, help me out on this. 
OK, help me out on this.  What is the use case for this device on this band?  It looks like an indoor rated router with a small omni antenna.  What am I missing here?    Ed

Use case?
Just started researching HaLow or 802.11ah. Agreed. Seems like this could be a substitute for a Hap AC3 adding HaLow coverage on 900 MHz in the home. It also seems like this might somehow bridge to Meshtastic and MQTT in the future. The housing does not look like a good fit for a rainy environment as you note.

900 MHz
The use case for this as it relates to AREDN, is probably to provide a link through trees (albeit with a relatively low throughput).    Given the frequency, you'd use a pair of them with high-gain Yagi antennas in a point to point configuration.

Rumor has it that a later release will have somewhat increased power output.

So here's an open ended
So here's an open ended comment/question.  Are there any 900mhz outdoor rated devices that are powerful enough to provide a ptp link through trees?  I'm talking not about a device that has Open WRT so it can also be a router, I'm asking about devices that are just radios that can be paired with a hAP ac2 or hAP ac3 to do the router function.  There are a lot of cases here where the last mile (literally) is a real pain with topography and trees, can we make an rf link using a non AREDN device appropriate for the ham slices of the 900 band where we can punch thru for the last mile?  This seems to be alluded to in the docs regarding using an xlink.

edit PS ... add on question.  I haven't yet fooled around with the virtual machine AREDN nodes, but can the X86 VM version of firmware run an xlink so we could just add this onto a site with an existing managed switch with the router on the VM?

It looks like this device has
It looks like this device has a 2.4GHz and HaLow radio.  Can the 2.4 interface with AREDN just like a device with 2.4 and 5GHz?  Or asked another way, if I get one and flash it, will it join up just like any other node, and mesh over 2.4GHz, or must it be DTD linked via the ethernet port?

Also, do we have any idea the expected range in a real world AREDN use case?  When they first released I saw their standard marketing range video.  Line of sight it can go a really long way, but that isn't the use case for this device.  Under ideal circumstances, with directional antennas, can we expect a block? A few blocks? A mile?  I'm not as familiar with 900MHz, as I am with UHF, VHF, 2.4 and 5GHz.  I have a buddy that is about a half a mile away.  We can both get up high, but in Chicago there is probably a tree in the way every few blocks, so we are probably shooting through like 5 trees.  Is there any chance this would make it through?   I have no intuition for 900MHz.  If someone has done some testing, please share.

900 Mhz fun
We had some success in New Jersey at a wooded location. We used a combination of 900 MHz Rockets with Yagis and Nanostation Loco M900s at the site. I still have a pair of the Nanostation Loco M900 running a recent nightly build. Let me know if you want to borrow them for some testing. They are outdoor rated so there should be no weather issues.

The HalowLink is an indoor only device and has an SMA connector. A better antenna would need a jumper cable. This unit will mesh on 2.4 GHz but only Babel routing is available in the firmware.

Path Loss
I think that the path loss at 900 will be 8.5dB less than with 2400 MHz,  I think trees will still be a problem, but maybe less at low RFs.  In my previous life I heard tales of difficulties US Army Signal Corps had with 250-400 MHz radios operating in forests in Germany.  Also, it is harder to get antenna gain at 900 than at 2400.

Poking around online shows me
Poking around online shows me the Ubiquity Rocket 900mhz is discontinued, and a few places are selling remaining stock between $600-1000 each.  Ouch.  A few used but this is not viable.  Ubiquity still shows stock of a very nice looking pair of yagi antennas meant to work with this radio for a few hundred. 

I guess this device was selected for us to consider because it is affordable.    Ed

900 MHz Yagi antennas
I found a few on eBay for less than a hundred.  Number of elements vary.
