David et al,
No mention yet. But in the usual #metoo way a few other projects have crawled out of the woodwork. Take a look at this https://destevez.net/2016/06/using-the-cc1101-and-beaglebone-black-for-ip-tr... for `128kbps in 100KHz and a similar one here http://wiki.oevsv.at/index.php/Kategorie:HHD70

Great to hear and thanks for the update Mark. Has there been any mention of supporting smaller bandwidths in the future?

Got a pair of these modems working! They are just running across the
bench
right now. I have an RPi3 and a MMDVM hotspot connected to the client
(via
a switch) with the master connected to a spare port on the back of my pfSense firewall. I'm using mode "22" which is 270KHz wide for about 220kbps of data bandwidth. This seems more than able to handle the
serving
of a web age and running the MMDVM. I also did a test in 500kbps mode
using
a wifi hotspot attached to the client. I was able to sustain a "wifi calling" cellphone conversation for over an hour with no issues.
For those not following the project, new firmware was released this
weekend
that allows tuning of the RF from 420-450MHz which is a great improvement over the EU only bandplan.

In case anyone feels the need:
It's pretty easy to file a petition through the ECFS. When you go to the main ECFS page https://www.fcc.gov/ecfs/filings in "Type of filing" select "petition for rule making", and fill out the rest of the form and upload your petition.
A couple useful pages from the FCC: <
https://www.publicknowledge.org/assets/uploads/blog/RP_FCCPetitiontoDeny.pdf
https://www.fcc.gov/about-fcc/rulemaking-process Here is a quick summary from the last one, three are more details on the page. *Organized comments*. *Clear explanation and support for views*. *Alternatives. * *Examples of concerns.* *Statutory limitations.*
It's also helpful to review recent amateur petitions and the FCC response. The rejections are a wealth of information on what not to do. It might be advisable to suggest RM-11392 and DA 08-1092 rejection, RM-11699 and DA 13-1918 rejection, as starting points since its somewhat related.
Don't use ham jargon, be sure sure to explain acronyms at least once in the filing, if repeated makes it easier to follow. Don't bash other amateur modes or practices. Don't use technical terms unless fully explained so a lawyer can understand, most on the Commission are non-tech types. Don't ask to ban anything, if you want that done make the case to the FCC that whatever it is is poor practice without requesting a ban......let them do it.
Do make your petition concise and to the point without a lot of rambling and legalese. Do provide a reason as to why it's a benefit to the amateur service as a whole, also in the public interest if it applies. Do have someone, with the background to understand it, proofread and comment. Do be ready for rebuttal of comments if there are any opposing....wait for the "reply to comment" period, this isn't an internet forum squabble. Keep comments/reply to civil and professional.

This keeps coming up. Has anyone ever submitted a petition for rule making to the FCC? Or are folks afraid that stirring the pot will get DATV banned on 70 cm?
