Hamvention Talk-In.. risky?
« on: May 12, 2017, 09:40:14 PM »

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).

From Part 97:

Quote
Broadcasting. Transmissions intended for reception by the general public, either direct or relayed.

So no, it would not be considered broadcasting.

I find Waze is a great app for traffic-adjusted, real-time driving directions....

While this is unusual to have it go all weekend. As long as they ID every 10 minutes they are good to go. Plus if they need to update information they can do it in an instant, plus it is a safe bet to assume most hams will have a 2 meter HT on them anyway.  145.525 according to the ARRL band plan is "Miscellaneous and experimental modes".

But I have a question, could vendors use APRS to mark their location? Would that be construed as commercial activity?

It would probably be permitted. Part 97.113(3)(ii) specifies an applicable exception to otherwise Prohibited Transmissions:

Quote
An amateur operator may notify other amateur operators of the availability for sale or trade of apparatus normally used in an amateur station, provided that such activity is not conducted on a regular basis

And given the general lack of FCC enforcement in the ham bands, I doubt that such transmissions would be scrutinized by the FCC in any case.

And the OP should understand that there is not a blanket prohibition on one-way transmissions, with "information bulletins" (such as planned by DARA) specifically permitted:

§97.111   Authorized transmissions.
(b) In addition to one-way transmissions specifically authorized elsewhere in this part, an amateur station may transmit the following types of one-way communications:
(6) Transmissions necessary to disseminate information bulletins.

Thanks for the reference, that answers my question regarding the transmission.

I was not being critical of the transmissions, just being cautious. That is why I asked.

thanks so much

I too was confused when I finally got around to listening to ARRL code practice... definitely a valid question!
