This page answers questions that we have received about the rules for the WRTC2014 competition.
Q: What is meant by “time period” in this rule? If Radio A is on 15M SSB, Radio B is not allowed on 15M SSB or 15M CW during the same time period).
Both radios cannot “flip flop” between bands. If Radio A makes a contact on 15M, Radio B cannot make a contact on 15M and then Radio A makes another on 15M. However, you can switch functions at any time. The requirement is that the other radio makes at least one QSO on another band.
Radio A 2305z QSO: 21007
Radio B 2306z QSO: 14250
Radio A 2307z QSO: 21008
Radio B 2308z QSO: 21250
Radio A 2309z QSO: 21009 <<<<<<<<< Not allowed! Radio A must change bands now.
Q: Is the tribander considered the same antenna for sharing (triplexer)?
For purposes of WRTC2014, the tribander in conjunction with the triplexer is considered 3 discreet (separate) antennas. You can think of it as having 3 monobanders for 10/15/20 Meters.
There are a total of 5 antennas for use between radios, one at a time for each radio.
Q: Which VFO’s are allowed to be used in each radio?
You may switch between VFO’s on each radio at any time. What is not allowed is use of a sub receiver.
You must receive on only one frequency at any time. No VFOA in left and VFOB in the right ears and no mixing of channels. While this may be possible for the operator, it becomes too confusing for the referee to follow. You may switch VFOs at any time.
Q: Am I allowed to use the A=B button to save a frequency in VFO B? I would not be on 2 VFOs at the same time.”
Yes, you can use VFO A and VFO B, or any memories to save frequencies. You are not allowed to receive on both frequencies at the same time. You can switch VFOs or memories at any time.
Q: Are Triplexers required?
While they are not required, it is the goal of WRTC2014 to create equal conditions for all competitors.
The committee will help you find one if you need help. You may construct your own, or use a commercial version. The triplexer separates the tribander into 3 separate “antennas” and may not amplify the signal in any way. Any losses must be tolerated, and cannot be compensated for.
Q: Do Maritime Mobile stations count for multipliers?
Maritime Mobile stations can be worked for QSO credit, but do not count for Multipliers.
Q: May we bring watt meters to monitor power?
The committee will provide official meters to monitor power. You can add your own if you want.
Q: Can I change the power outlets from USA to Euro style? Or use adapters to convert to my radios power requirement?
Yes you can adapt the outlets in any way necessary to make your equipment work. The committee will have some adapters available, or may be purchased locally. It is recommended the teams bring whatever is necessary for their particular setup.
Q: Is it allowed to use a QRP TX and a 100W amp to achieve 100W or does it have to be an all in one transceiver? E.g., Elecraft KX3 + KXPA100
Absolutely. Teams are allowed to bring any equipment they want or need to transmit 100W. The organizers will provide power monitors at the output of the transmitter or amp in this case. The only requirement is that you do not exceed the power limit. Any losses through bandpass filters, etc must be accepted, since filtering must be connected between the power monitors and antennas.
Q: I understand that the super check partial (SCP) database is not allowed for the WRTC competition. In Russia, this same rule was implemented but they allowed a fill database for use with headquarter exchanges. Will this be allowed?
Yes, you may have HQ exchange information filled automatically, or manually. You may have it available on paper or in a database. The CALL SIGNS may NOT appear automatically, such as with Super Check Partial.
However, just as with zone information the software can provide the HQ exchange information automatically.
Q: Are the WRTC stations going to hold the privileges of Extra class stations what concerns the frequency allocation?
Yes, all teams will use the same privileges. The US allocations are:
Q: CW QSOs are allowed all over the band, right?
The FCC regulations permit the use of CW on any frequency. However, the rules for the IARU Radiosport contest prohibit this. Therefore, WRTC will follow this rule: All SSB QSOs must be in the SSB segment and all CW QSOs must be in the CW segment. Cross mode is not allowed.
Q: What happens in the event an antenna fails?
Your referee will notify the site team. If repairs are necessary and easily done, they will attempt to fix the problem. You may use the working antennas in the interim.
Under no circumstances is anyone allowed to climb the tower. The only thing a team member can do is adjust the lengths and orientation of the dipoles.
Q: Just to be clear – the 80m and 40m dipoles cannot be used even as RX antennas only on high bands (unless the tribander breaks)?
You may use any antenna on any band, but you cannot share it with the other radio.
For WRTC purposes, the Triplexer separates the Tribander into 3 discreet antennas. Sharing of the Tribander is obviously not prohibited in this manner.
EX: Radio A is on 21025 with the Tribander (through the Triplexer) running a pileup.
- Radio B can listen on 21025 with the 40M dipole, but CANNOT transmit.
- Radio A can also use the 40M dipole to listen or transmit, but NOT while Radio B is using it.
- Radio B can go to any other band and use any antenna not being used by Radio A.
In summary, you can use any free antenna on either radio for TX or RX. You may not split them to RX on both radios.
Q: Can you advise if we are permitted to make changes to the length of the antennas remotely? For example by using a remote controlled relay to add or remove a length of wire to adjust resonance from inside the shack? This would remove the need for physical adjustments and/or ATUs.
A. No, it is not allowed to remotely tune the ends of the wire antennas. All adjustments must be made manually at the ends which are just above ground level. You may make them at any time during the event.
Q. Is it permitted for Radio B to go the the same band as Radio A to work
multipliers while Radio A is running (assume they are interlocked so
there is only one signal transmitted at a time)?
A. No, you cannot transmit on the same band as the other radio. If Radio B makes a QSO on the same band as Radio A, the next qso on that band must be made by Radio B. Radio A must go to another band, or not transmit. Additionally, they may not share the same antenna. (No alternate CQing etc on same band with same antenna.)
Q: Is it permitted for Radio B to go the Radio A band just to tune around and fill up the band map on that band?
A. Yes, Radio B can listen anywhere at any time. However, it cannot use the same antenna as Radio A (no splitting of RX line). For this competition, the Tribander is considered as 3 separate antennas for 10/15/20 Meters. Radio B may also listen to the audio of Radio A if desired.
Q: Do I understand correctly that my single stereo plug will hear both radios - with the tip for one radio, the ring for the other radio, and the body of the plug common for both radios?
16.8.1 “The audio output should be terminated in a 3.5mm headphone female jack for the referee to plug into”
16.8 “… The audio must be isolated so the referee may listen to either channel or both at the same time.”
A: Yes, that is correct.
Q: Can I assume that isolated includes audio ground loop elimination – if relevant to a station design?
16.8 “If the referee uses his or her own headphones, it must not interfere with the team’s audio in any way.”
A: If your box produces hum or is mismatched in such a way that the team’s audio levels are too low; that is a problem. Also, there should be no crosstalk between channels.
It is the team’s responsibility to provide an audio output that is isolated from their own. This would allow a standard stereo headphone to plug in and monitor both channels.
Q: If I bring my own switch box and phones, is there a suggested minimum impedance to ensure no interfere with the team’s audio in any way?
A: Typical impedance is around 35-75 ohms. You should not go too far below that.
