$NN Mariam was poised, knowledgeable and well spoken. In this attached clip, Mariam states no interference has been reported in all the years of testing. The opposition doesn't have any specific examples of interference. https://t.co/ySdZeVAWjc

$NN I have been approached by folks about last weeks Congressional hearing. I watched the entire hearing and spoke to well informed participants. The opinion is that the hearing went exactly as hoped. This was not a political debate in which a candidate tries to land a punch.

@darkstarsats @dylan_ascencios @dan_tmt and why would anyone have to retool antennas or receivers when almost all (but not all) Part 15 are center tuned to 915, which $NN doesn't want. Why are 10 Mhz around 915 not enough when EU and China do it with 5 or 6 MHz?

@dylan_ascencios @darkstarsats @dan_tmt @darkstarsats ty for the work you have done on $NN. Do you have a view on why 907-918 MHz is not enough for Part 15 when Europe and China allocate ~half as much for similar devices and don't have any problems? Note that most Part 15 devices are center tuned to 915. TYIA

??? Two things can be true at the same time. In that you can have a slow down from weak international travel (administration) domestically, weak lower end consumer, glp, and inflation that is dragging down sales. And yet you can continue to invest in new store counts if the economics of your model are intact AND you have the balance sheet to continue to invest in your business. The competitors you cited besides macro have other issues impacting their ability to invest; PTLO has a serious balance sheet issue SG has an economic model problem... *turns out 18$ salads is a tough business*. Mcdonalds increased store openings in 2008 AND 2009 even as SSS growth was slowing every year 06-09....those investments worked out just fine because the model works. $SHAK SSS still going to print solidly positive for the year while most chains won't this year (and thats without the added store count). Shak has issues, all restaurants are tough and tough to scale and Rob and the cfo are far from Mcdonalds level of execution, but at 1x sales and a +20% restaurant margin model with 4m AUV theres a lot more room to the upside then the downside at current levels. I don't think they get to the dream target of 1500 stores, but that would be a 10x from here, whats the downside, at almost 1x current....30% maybe? I'll take that asymmetric set up.

You wouldn't know it based on the way investors on this platform talk about homebuilders and the housing market in general but Berkshire Hathaway's deal for $TMHC is the THIRD announced takeout of a publicly traded homebuilder this year. Sentiment in the space has rarely been worse than it is now, but some longer term thinkers see the opportunity... $XHB $ITB $TPH $UHG
