I received this as part of an email on one of the forums I follow:
(extracted) "As you can probably imagine, the change of
venue is going to make Talk-In very busy and very important to our
visitors this time. In an effort to be able to help as many hams as
possible, and reduce traffic and repetitive questions on our primary
Talk-In frequency of 146.94- 123.0, we will be utilizing an
informational bulletin system this year that will provide answers to
many of the frequently asked questions and provide important general
information to those approaching the area. The bulletin system will be
transmitting on 145.525 where attendees and vendors can listen to get
the information they need."
-------------------------------------
I do not want to be splitting hairs but does the "informational bulletin system" become classified as "broadcasting"? It is not a two-way dialog, it is a one-way transmission. I recall that this might be expressly prohibited on amateur frequencies.
Since this is such a high visibility event someone may want to rethink this.
It may be too late to get one of those travelers information AM transmitters (maybe they can borrow one from a local organization).
