SC ARES Information System - Florence Update
From: On Behalf Of SC ARES Information System
Sent: Thursday, September 13, 2018 11:37 AM
Twenty-four coverage at the State EOC radio room begins at 0800 on Thursday September 13, 2018.
At 0900 SCHEART conducts weekly communications check with healthcare facilities. After the healthcare net, the SCHEART VHF/UHF will remain linked for the duration of the storm. Periodic nets to brief field staff and/or confirm stations will happen at four-hour intervals. The first net will be at 10:00AM Thursday.
SCHEART Analog VHF/UHF Scheduled Net Times are:
02:00 AM, 06:00 AM, 10:00 AM, 02:00 PM, 06:00 PM, 10:00 PM
SCHEART DMR system is in emergency mode which restricts PRN talk group to South Carolina and terminates all dynamic talk groups. ARES and AUXCOMM members are requested to monitor the PRN talk group for coordination information and instructions and keep the analog system open for tactical and emergency traffic.
Statewide Simplex Channel is 146.595 with PL of 156.7 Hz and can be used for relaying traffic to the SEOC.
HF operations will begin at noon on Thursday. HF is a back-up to the statewide VHF/UHF network. The published frequencies for SC ARES nets are 3.990 or 3.995 +/- for nights and 7.232 +/- days bands permitting.
State EOC will monitor the SCHEART repeater networks, Simplex and HF frequencies. Field operators should follow guidance and frequencies listed in the South Carolina ARES and RACES Auxiliary Communication Tactical Communications Guide which is available for download on the website.
Tactical Call Signs will be used during this response effort. Operators are responsible for following FCC regulation on proper station identification. Stations should call “State EOC” when calling the radio room. The State EOC will call County EOC’s by the county and healthcare facilities by name. Stations not associated with with a partner agency will use their normal call sign. All operators are encourage to 1) Keep transmissions short, 2) Pass essential information as clearly as possible, 3) Follow Net Control Station directions 4) When you check into a net indicating you are staffing a partner facility, or offering to assist in the response, do not leave the frequency without obtaining a release from Net Control Station. The only except is at an agency location where there’s multiple operators and the frequency is being monitor by another operator if you step away from the radio.
Field operators who observe a potential life-threatening situation, should immediately immediately contact 911. If you are unable to reach 911, use your county tactical frequency (reference ARES/RACES Tactical Guide link above) to contact the county EOC. If you are unable to make local contact, the emergency may be reported to the State EOC radio room. Information they will need: Complete and specific information on situation location, name of the person making the request, your call sign, and facts about the emergency condition. The State EOC radio room will attempt to assist but the process to get back to local emergency management take longer than making local contact.
All Operators are reminded to be polite and respectful as this situation is very stressful. Please be professional as possible. Field Operators do not self deploy and put yourself in harms- way. ARES/RACES operators should follow direction provide by their field management and local emergency officials.
This plan will adapt as conditions change. All amateur radio operators are encouraged to monitor the SCHEART network for updated information from the State EOC and listen to their county designated repeater for local information and reports .

Update. Over a few weeks in early summer, the SCHEART network along with other amateur repeaters in the state had experienced frequent malicious interference from a rogue station. ? This has resulted in adverse impacts to the weekly training nets and periods where authorized communications on the repeaters were interrupted by control operators attempting to restrict the rogue station’s range. In the background, amateurs along with State and Federal agencies worked to isolate the transmission source and identify the individual involved.?The task force was successful in early July. The suspect was not a licensed amateur operator.? However, he surrendered amateur radio equipment when confronted by law enforcement.? Due to further pending action, more information is not available at this time. SCHEART thanks all the hams who participated in the effort to identify the rogue station and to all South Carolina Amateurs who acted professionally over the air when confronted by this operator. UPDATE- The documentation for this stations operations was turned over to the FCC for action. ? Kent KQ4KK ?

Checking into a net (or calling another station!)
Contrary to intuition and some practices, there is NO requirement to identify the station that you are CALLING. Let’s think about this for a moment. If you are SPECIFICALLY calling a station while you are NOT on a net, then identifying the station to whom you are directing your transmission not only makes sense, but is necessary for that station to know that you are calling them.
|
However, when checking into a directed net, such as the SCHEART Thursday morning nets, or the Sunday evening ARES nets, it is NOT necessary to state that you are calling the Net Control Station, or NCS. The reason is that the NCS has stated in his opening statement that “THIS IS A DIRECTED NET, AND ALL TRAFFIC MUST BE DIRECTED TO THE NET CONTROL STATION”. So, when checking into a directed net, it makes no sense to call “Net Control…..Net Control”, since ALL transmissions are implied to be directed to the Net Control Station. Calling “Net Control” unnecessarily takes up net time. What you WANT to do is to identify yourself in the manner prescribed by the NCS.
|
|
Many stations check into the SCHEART or SCARES net using the following statements:
|
“Net Control”……(pause for 3 seconds)……and once again call ”Net Control, this is KA4XX, etc etc”. Calling “Net Control” not only once, but twice during an attempted check in, is not necessary and wastes net time.
|
The “pause for 3 seconds” is an INSTRUCTION to each station by the Net Control based upon the PHYSICAL requirements and restraints of the SCHEART system. The pause is VERY IMPORTANT for any net using the SCHEART linked repeater system. The system consists of 16 VHF repeaters and 15 UHF repeaters, each of which must “link up” or “connect” to the main system. There are several different methods and equipment designs used depending on the location and vintage of each repeater in the system, each of which take varying amounts of time to link into the main system. The 3 second pause is not an arbitrary number, it was established to specifically allow each repeater time to link into the system. If you do NOT wait 3 seconds between keying your microphone (sending your signal to your local repeater and subsequently to the system), whatever you say BEFORE the 3 second delay may not be heard by other stations, INCLUDING the Net Control Station! 3 seconds does not mean 1 or 2 seconds. Get into the habit whenever using the linked SCHEART repeater system of keying your microphone, then counting to yourself “one thousand one, one thousand two, one thousand three” BEFORE any words travel from your vocal cords to the microphone.
|
It is very good practice to assure that you are not trying to check in at the EXACT time that another station is trying to do so. That is called “DOUBLING”. Here are two alternative methods to check into the net.
|
|
One method is to simply state “THIS IS” (then unkey and wait 3 seconds to see if any other station is doubling with your check in). Then rekey and say the required information to check into the net. You do NOT need to repeat the words “THIS IS”!!
|
Example: “This is”……pause 3 seconds……”WA4XXX…..(continue with check in information that is requested by NCS, Name, Location, Affiliations, etc)….No traffic, OVER.”
|
|
Another method is to simply state your call sign “AX4XX” (then unkey and wait 3 seconds to see if any other station is doubling with your check in). Then rekey and say the required information to check into the net. REMEMBER, there is NO REQUIREMENT, especially during net check-in, to identify the station you are calling if that station is the NCS.
|
Example: “AX4XX” (then unkey and wait 3 seconds to see if any other station is doubling with your check in”)…..Then rekey and say your call phonetically “Alpha Xray Four Xray Xray”, then state your name, location, and other information requested by NCS. Remember to add if you have traffic or information for the net before turning it back to the NCS with the procedural sign “OVER”.
|
For the SCHEART Thursday morning net, you should identify yourself with your Amateur Radio Call Sign, your first name (or nickname), your County where you are located, and if you are affiliated with a Hospital Radio Response Team, or a member of the Medical Reserve Corps. The SCHEART NCS does NOT ask for, nor record affiliations such as ARES, RACES, AUXCOMM qualifications, and so on, so there is no need to state them.
|
For the ARES Sunday evening net, you should identify yourself with your Amateur Radio Call Sign, your first name (or nickname) and the County where you are located. You do NOT need to identify any other affiliations such as AUXCOMM qualifications, hospital response teams, and so on, unless you want to, Your qualifications are (or should be) listed in the ARES database.
|
There is no such thing as “IN and OUT” in a directed net. That terminology is used for informal type nets and mean that you want to check in but also want to check out at the same time, because you have nothing for the net. This terminology has NO USE in a directed net. When checking into a directed net, you are expected to remain on frequency and ATTENTIVE to the NCS until you are excused either individually, or by invitation from the NCS. If you must leave the net, you are expected to call the NCS and request that you be granted permission to secure your station. The reason for this protocol is that the NCS may have a specific assignment for your station, or may have traffic or information for your location. Remember that when you check into the SCHEART or the SCARES nets, that they are TRAINING NETS held in order to prepare you for incidents or emergencies when your communications skills will be needed.
|
Lastly, it is NOT appropriate to check in for another station. Each station should and must check into the net separately using their own assigned call sign and identification. The reasoning is the same as stated previously, that the NCS may have assignments or information for any station that is checked into the net. Each station that checks in is expected to be available to listen to the instructions and/or assignments by the NCS.
|
As a special note to operators using YAESU equipment: BE SURE THAT YOUR “WIRES” MODE IS NOT ENABLE BEFORE CHECKING INTO A SCHEART NET. The reason is that the WIRES mode places a series of tones on your signal, and your voice can not be heard at the same time these tones are being sent by your transmitter.
|
These guidelines are meant to assist you, the operator, in accepted procedures, and following them will help the nets to run smoother and more efficiently.

FCC Rules against Baofeng Radio
A month ago, a local ham brought me his new BAOFENG that he got from BaofengUSA via Amazon, to program and I did, but it would not transmit below 145mhz. ? Take the cover off the back and the radio said it could transmit 134-174 and 430-474 or about. ? Tried RT Solutions software and CHIRP, could not get it to transmit below 145. ? Used the BAOFENG software, which allows you to set the limits<sic>. And I put it at 144-174 and it works fine. ? If you buy a Baofeng, be aware of the legal dynamics that is currently going on with this type of radio. It may work, or it may not. Spend your $50 wisely. ? Kent KQ4KK
FCC Rules Baofeng Radio's?are an "unauthorized RF device". Orders immediate stop of sales.

Hams have been sharing info on what bulb manufacturers have had low and high interference for a couple/few years. Maybe spend some internet time seeking out those reports and see if you can substitute some good ones for what you have. I've seen that type of discussion on several web sites.
As to FCC approval, there has been some talk about people getting approval and then downgrading the supply without getting re-certification. A board having good EMI protection is approved and then once it hits production the EMI suppressing components aren't installed. The holes are still there in the circuit board for the parts -- just that in order to save money for the manufacturer only those parts needed to make the lights turn on are installed. The EMI stuff isn't needed for that so they leave them out. There has been documentation of that actually happening. So far the FCC hasn't been pushing very hard for the manufacturers to do the right thing.
