Kirkland Emergency Communications Team took delivery of 10 ID-1s, a ID-RP2C<br>
Controller and a ID-R3 Data Module in 2010. The intent was to link our<br>
EOC-Radio Room with our 7 remotes sites and two portable units with a high<br>
speed data network. However we did not develop functional requirement<br>
specifications and we did not do any preliminary feasibility testing before<br>
equipment order was placed.<br>
I spent two years attempting to develop a working network. Below are some<br>
of my findings.<br>
1. The radio to radio path has to be line of sight or via a good<br>
reliable reflector. The best tool that I found to determine if a viable<br>
path exists is Radio Mobile. I did a number of field tests, ID-1 to ID-1<br>
and ID-1 to the K7LWH DD node on the Lincoln Tower in Belleview. In all<br>
tests where the terrain extended into the direct path a connection could not<br>
be established. Our only fixed location in Kirkland with K7LWH DD node is<br>
the city hall. We have only on fire station that could see the antenna on<br>
the City Hall. With the new construction I am not sure if it is currently a<br>
good path.<br>
2. ID-1 to ID-1 DD mode is simplex. A 1MB image takes about 2.5<br>
minutes to transfer.<br>
3. I am not sure of what the through put would be for a DD Gateway<br>
(K7KFD) 2, 3 or 4 ID-1's were connected at the same time and passing files.<br>
4. I was told by ICOM, a few years ago, that the ID-1s could not be<br>
meshed. If the firmware could be reprogrammed to be compatible with<br>
Broadband-Hamnet, many of us may be willing to take the ID-1 off the shelf<br>
and get them on the air.<br>
5. There are groups that have established links using ID-1s back to<br>
back but I determined that our group did not have the human recourse to<br>
establish and maintain a reliable link in a disaster at this time.<br>
<br>
I for one would like to see an ID-1 networking "cookbook" if one is ever<br>
written. John Haze K7VE was a recourse the rest was through trial and<br>
error. I am willing to share my rough notes (they are rough) with anyone<br>
that may be interested.<br>
<br>
In the mean time I am looking to HamWAN and Broadband-Hamnet to handle high<br>
speed data transfer in Kirkland.<br>

Another local EmComm group has 7 ID-1's that, AFAIK, aren't yet being used.<br>
Some of the folks there that I've talked to have mentioned propagation<br>
issues as the primary impediment.<br>
<br>
I bet they'd be very happy to have a cookbook process in place where they<br>
could get on and connect with a node like Paine Field or set up one of their<br>
own.<br>
