ID Every 10 Minutes
B. Johnston W3BE
Q. Our radio
club assists at public-service events by running a net to pass informal traffic between several
operators located around the site. Our club organizer has said: “All stations will be operating under
the club call sign and individual operators are only to identify themselves using their tactical call signs. Individual
operators will not identify with either their own call signs or with the club call sign. Only net control will identify with
an FCC-assigned call sign, the club call sign.” He said that would satisfy the legal identification
requirements for all operators at the event. I asked how this would be legal. He simply said that it's legal. I
don't understand how.
No, each and every station transmitting in the network should be making the required Section 97.119(a) station identification announcements. It says: each amateur station, except a space station or telecommand station, must transmit its assigned call sign on
its transmitting channel at the end of each communication, and at least every 10 minutes during a communication, for the purpose
of clearly making the source of the transmissions from the station known to those receiving the transmissions.
From those announcements, the identity of
the station licensee bearing the Section 97.103 responsibility for the station transmitting properly can be determined by consulting the ULS. For an amateur station to fail to transmit the required Section 97.119(a) station identification announcements would make our Maintenance Monitors and other official and our unofficial monitoring efforts meaningless.
Tactical call signs might also be transmitted within a network of stations. In this
instance, the club organizer wants to identify individual operators – presumably the Section 97.105 control operators – for the functioning convenience of the network controller. But they are not FCC-assigned call signs. No amateur station
transmitting from a place where the FCC regulates our amateur service may transmit in its Section 97.119(a) identification announcement any call sign not authorized to that station.
Q. Can tactical call signs be used during RACES operation? I ask this because 50 plus years ago, those of us involved
in CD communications in this county and operating under the then RACES rules regularly used tactical call signs. We had
a letter from the Engineer - in Charge of our local FCC office indicating this was an acceptable practice during RACES drills.
A. Yes, but not as
a substitute for our mandatory Section 97.119(a) station identification announcements. The rules for RACES reside in Section 97.405. There is no mention of any special rules or exceptions for (“EmComm 405”) station identification announcements.
A half-century ago, in places where the FCC regulates, our amateur service community relied upon the former Field Engineering Bureau for official maintenance monitoring. Now,
we rely upon self-monitoring and our volunteer Maintenance Monitors.
the net control station have to ID every time it talks to another station or is it OK to just ID every 10 minutes?
A. There are no special rules for our
networks. The all-purpose Section 97.119(a) station identification announcement must always be transmitted at the conclusion of a QSO or other communications. When a transmission continues for more than
10 minutes, the ID must also be transmitted at least every 10 minutes.
Not all networks have a controller person directing the intercommunications. Where
there is someone, however, the 10-minute protocol seems to be sufficient for the stated purpose of clearly making
the source of the transmissions from the station known to those receiving the transmissions.
Q. I've heard some confusion about a group QSO and the ID requirements for each individual
station in the group. The main point being whether a station which has been part of the group, but after IDing has been silent
for some period of time is required to ID on the next 10 minute interval. I have maintained that as long as that station
properly ID'd their last transmission they are under no obligation to transmit further identification when they have been
silent even for a period of longer than 10 minutes. Instead, that station may continue to be silent and not ID until,
in the natural course of the conversation, they make their next transmission, at which time they would ID again, even though
more than 10 minutes have elapsed since their previous ID. Your comments please.
A. It is Section 97.119(a) that applies to each station participating in the group QSO. It does not include special provisions for station participating
in a group QSO. A good amateur practice might be for the Section 97.105 control operator of one of the participating stations to call for a station break every 10 minutes to allow the participating stations to
transmit their station identification announcements.
Q. Some Part 90 Land Mobile Radio Service mobile units transmit the ID automatically so that the dispatchers
know which one is transmitting. It's not a rule requirement - only to enhance their intercommunications.
A. Automatically transmitted Section 97.119(a) amateur station identification announcements could also be a great operating aid for hams. Some vehicle broadcast receivers have a somewhat similar feature, Radio Data
System or (“RDS”). They display the station's call sign and format, the name of the music being played, the
score of the game being described, et al. Just consider the possibilities for ham radio: a pre-packaged message that includes
the station's QTH, apparatus, achievements, interests, etc. Such could eliminate the need for cramming trolling
lures into self-assigned indicators into appendages to station call signs.
Q. Our club station repeater is installed in a hospital. Its transmissions
have become erratic. The hospital has changed ownership and the new owners refuse to allow us access. What is our recourse?
A. The pertinent requirement is in Section 97.5(a). It says: The station apparatus must be under the physical control of a person named in an amateur station license grant
on the ULS consolidated license database or a person authorized for alien reciprocal operation by §97.107 of this part,
before the station may transmit on any amateur service frequency from any place that is: (1)
Within 50 km of the Earth's surface and at a place where the amateur service is regulated by the FCC.
So, unless your Section 97.5(a)(2) club station trustee has the Section 97.5(a) station apparatus under physical control, the station should not be transmitting on our amateur service bands – at least not while your
club station call sign is being sent in the Section 97.119(a) station identification announcements. Those announcements determine the Section 97.103(a) station licensee responsible for the proper operation of the station in accordance with the FCC rules. Consult the ULS for the name and mailing address of that station licensee.
Unless the transmissions cease, or the situation becomes compliant, one recourse would be to
request cancellation of the club station license: FCC, 1270 Fairfield Road, Gettysburg, PA 17325-7245 and to notify our Maintenance Monitors and your local or regional area Section 97.3(a)(22) frequency coordinator.
Q. We are installing a packet digipeater
transmitting on 145.570 Mhz. It will transmit the control operator's call sign in the packet stream. It will also be transmitted
every 60 minutes as a beacon. We think this meets the necessary FCC requirements. Do you agree?
A. It very well could be compliant. There are no special rules for
a packet digipeater - an amateur station that receives a packet, processes it, and retransmits it on the same
channel. A Section 97.3(a)(40) repeater as an amateur station that simultaneously retransmits the transmission of another amateur station on a different
channel or channels. Your digipeter, therefore does not qualify for the special Section 97.205 accommodations afforded repeaters in such as automatic control, coordination recognition, etc. Here's where it stands:
Section 97.221 provides unique accommodations for an automatically controlled digital station (ACDS) - other than an auxiliary station,
a beacon station, a repeater station, an earth station, a space station, or a space telecommand station. Perhaps those accommodations
could be useful in your digipeater design.
Section 97.205 authorizes repeaters to receive and retransmit on 145.570 MHz. An ACDS, however, is not similarly confined to repeater segments
in the 2-meter band. So, unless there is a nearby repeater already on your chosen channel, your selection of that repeater
channel may be suitable. Confirm with your local frequency coordinator that it will not be interfering with any repeaters.
Your Section 97.103(a) station licensee will have certain duties and your designated its Section 97.105 control operator will have certain other duties. Read BE Informed No. 1 for a checklist of each. The person listed on the ULS for the call sign transmitted in the station identification announcement is your Section 97.5(a) station licensee. When devising your station's Section 97.119(a) station identification procedure, please give due consideration to the volunteer work of our Maintenance Monitors and our self-monitoring.
Section 97.119(b) says the call sign must be transmitted with an emission authorized for the transmitting channel in one of the following
(1) By a CW emission.
When keyed by an automatic device used only for identification, the speed must not exceed 20 words per minute;
(2) By a phone emission in the English
language. Use of a phonetic alphabet as an aid for correct station identification is encouraged;
(3) By a RTTY emission using a specified digital code when all or part
of the communications are transmitted by a RTTY or data emission;
(4) By an image emission conforming to the applicable transmission standards, either
color or monochrome, of Section 73.682(a) of the FCC Rules when all or part of the communications are transmitted in the same
Q. I use Echolink
as a client, not in sysop or repeater mode. In this case I have a long mike cable but no control over the transmitter. When
using a station in another country, do CEPT, reciprocal agreements, etc. not apply because I cannot be a control operator?
Is my USA call sign alone sufficient to identify, or do I identify as though I were in that country (except every 10 minutes
if that country allows less often)? How do I know which other USA and per-country rules are in effect for a given station?
A. Part 97 is the key rules platform for amateur stations transmitting from places where the FCC regulates our amateur service. It contains no specific provisions for Echolink. Neither does the international Radio Regulations.
Apparently, in the system to which you refer, amateur stations interact with a local station that also interacts with the
Internet. All international intercommunications take place over the Internet and all amateur station radio links are local.
Therefore, no direct amateur station to amateur station international intercommunication takes place solely by amateur radio.
In the case of an amateur station
transmitting under the authority of an amateur station license grant shown on the ULS, it should be transmitting its Section 97.119(a) station identification announcement at least every 10 minutes. In the case of an amateur station transmitting under the authority of another country, the protocol
for station identification is for the regulatory authority there to determine.
Q. We have a local ham driving everyone nuts complaining about needing to ID at the
end of a conversation. He states that anything said after the call sign is illegal and would require another ID;
Things like (call sign) clear, (call sign) monitoring, etc. My understanding is that if the call is included
in the last transmission, that meets the requirement. What's your take?
A. The rule to which he is referring is Section 97.119(a) station identification announcement. It says that each amateur station, except a space station or telecommand station, must transmit its assigned call sign
on its transmitting channel at the end of each communication, and at least every 10 minutes during a communication, for the
purpose of clearly making the source of the transmissions from the station known to those receiving the transmissions. Because
from here there is no speculation on what hams can or cannot get away with, we’ll leave it at that.
But let us not allow that stand in the way of some pontification
about our antiquated protocols for station identification. They were barely appropriate for the 20th Century, let
alone for the 21st. They are how-to-ism artifacts from the very beginnings of wire line telegraphy and they now
attract nit-picking. Station identification can and should be carried out automatically.
Q. Some Part 90 Land Mobile Radio Service mobile units transmit the ID automatically
so that the dispatchers know which one is transmitting. It's not a rule requirement - only to enhance their intercommunications.
A. Enhanced automatically
transmitted Section 97.119(a) amateur station identification announcements could be a great operating aid for hams. Some vehicle broadcast receivers have a somewhat similar feature. They display
the station's call sign and format, the name of the music being played, the score of the game being described, et al. Just
consider the possibilities for ham radio: a pre-packaged message that includes the station's QTH, apparatus, achievements,
interests, etc. Such could eliminate the need for cramming trolling lures into self-assigned indicators into appendages
to station call signs.
