EMcom vehicle setup
by Jason Linz 25 Aug '21

25 Aug '21

Hello from North Dakota Earlier this year I purchased an Ambulance to set up for emcom as well as camping. As I am in North Dakota there is no HamWAN system in place. I do hope to travel to surrounding states so I would like to incorporate some highspeed data in the setup. I would like to put a wireless access point in for local connectivity for cameras. Has anyone tried to set something up like this? Also I have thought for a few years about building a HamWAN cell site to allow access around town. I am still looking at roof tops to think if I can find something that could work. A lot of pieces to find and put together so any info would be appreciated. Thank you Jason Linz ND0JL

Re: [HamWAN PSDR] "r2" Version Supports all Three Band Widths - MikroTik QRT 5ac 5GHz outdoor flat panel 24dBi antenna

Channel bandwidth is different from channel tuning. One is occupied spectrum, the other is transmit frequency. 73, Don N2IRZ -----Original Message----- Dear PSDR List Members, HamWAN's PDF comparing various devices shows the QRT 5 ac: http://hamwan.org/Standards/Component%20Engineering/Client%20Hardware/anten… However, on the webpage http://hamwan.org/Standards/Component%20Engineering/Client%20Hardware.html it states: "Avoid Mikrotik's 802.11ac modems. These are incapable of tuning the 5 and 10 MHz channels used by HamWAN and are therefore incompatible." It is not unusual to find outdated material relating to electronic devices, and I think this is the case here, so I thought it best to check with the manufacturer. Below is the response from MikroTik Support confirming that the new version of the QRT 5 ac also supports 5 and 10 MHz band widths because of a new chipset in the "r2" revision. Just need to make sure you don't get the old version. 73 Alan WX7L

(Jira) <support(a)mikrotik.com> Date: Mon, Aug 16, 2021 at 4:33 AM Subject: MikroTik support #[SUP-57126]: Question about QRT 5 ac To: <WX7L(a)westseattlearc.org> —-—-—-— Please REPLY ABOVE THIS LINE ^ (for faster response, use our support portal <https://help.mikrotik.com/servicedesk/>). Hello, Apologies for the delayed response. QRT 5ac is quite a unique situation. After additional investigation regarding the support of 5/10Mhz channel-width, I can say that, if you buy the router today, it should support these channel-widths. It has two public revisions, where the newer one (/r2) has a different wireless chipset (QCA-98*9*2) that supports these channel-widths when compared to the old one (QCA-98*8*2). To make sure you are getting the right one, you can ask the distributor to ensure that you will have the *r2* revision, which can be found on the box/case label at the end of serial number, for example - A13B0DXXXXXX/0XX/*r2*. I will make sure to update the Web description of the QRT 5ac, as it currently shows that it has QCA-9882 wireless chip and the older one is long discontinued. Best regards, Rūdolfs P.
