-
-
- -------------------------------------------------------------------
-
- FAQ: US Automatic Reciprocal Operation in Canada
-
-
- Q1: I have an FCC-issued amateur license. What do I have to do to
- operate an amateur radio station in Canada?
-
- A: A reciprocity treaty, TIAS 2508, provides for US-Canada reciprocal
- operation of amateur radio stations. No application, registration, or
- fee is required. You are automatically eligible to operate in Canada
- if all three of these conditions apply:
-
- 1. You have a valid FCC-issued license;
- 2. You are a US Citizen;
- 3. You are a resident of the US (if you're not a US resident,
- please direct your questions to a Canadian official. As I
- understand it, if you become a Canadian resident, your US
- license is good for a while, but they expect you to get
- a Canadian one eventually).
-
- (GR2.45.1.a, RIC-25 p. 9)
-
-
- Q2: What privileges do Canadian operators have?
-
- A: Legally, Canada has no separate phone band or other mode
- restrictions. Instead, they adhere, on a voluntary basis, to a
- bandplan, similar to the way we use 160 meters. (The IARU Region 2
- bandplan can be found in Chapter 2 of the ARRL Operating Manual.)
- Canadian amateur bands are the same as those in the US up through 1.2
- GHz, except they have all of 220-225 MHz, and they only have 430-450
- MHz. There are, however, bandwidth limits (-26 db):
-
- 160, 80, 40, 20, 17, 15, 12 meters: 6 kHz maximum bandwidth
- 30 meters: 1 kHz
- 10 meters: 20 kHz
- 6, 2 meters: 30 kHz
- 220: 100 kHz
- 440, 902: 12 MHz
- 1.2 GHz and up: none specified
-
- (Schedule II, RIC-25 p. 15)
-
-
- Q3: What privileges am I allowed while operating in Canada?
-
- A: All foreign amateurs, including those from the US, are assigned
- reciprocal privileges according to the Morse Code speed needed to
- qualify for their license:
-
- 12+ wpm: All "Advanced + 12" privileges
- (i.e., *all* Canadian privileges)
-
- [US General, Advanced, Extra Class]
-
- 5-11 wpm: All privileges above 30 MHz,
- PLUS CW and CW only on all bands below 30 MHz;
- limited to Basic privileges [*]
-
- [*] *Canadian* Basic + 5 wpm licensees are allowed
- full access above 30 MHz, plus (full) access to
- 80 and 160, only. However, the above *is* what
- the rules say about *foreign* amateurs operating
- in Canada.
-
- [US Novice Class, Technician + 5 WPM code]
-
- 0-4 wpm: All privileges above 30 MHz, with Advanced privileges
-
- [US Technician without code]
-
- (GR2.45.2,3,4, RIC-25 p. 9)
-
-
- Q4: What's the difference between Basic and Advanced?
-
- A: Without Advanced Qualification (or equivalent), you may not:
-
- 1. posess or install a transmitter or amplifier that isn't
- commercially designed and manufatured;
- 2. posess or install any radio apparatus manufactured specifically
- for use as a repeater where input and output are on the same band;
- 3. install a repeater where input and output are on the same band;
- 4. set up a club station
-
- (GR2.47, RIC-25 p. 10)
-
- Basic operators are also limited to lower power.
-
-
- Q5: What are the power limits?
-
- A: An Advanced operator or equivalent can use up to 1000 W dc input,
- if power is measured as input to the final stage, *or* an output of
- 2250 W PEP SSB/750 W carrier power for other modes, if output power is
- measured.
-
- A Basic operator or equivalent is limited to 250 W input, *or*
- 560 W PEP SSB/ 190 W carrier power other modes, output.
-
- It is illegal in Canada to posess or install a transmitter or
- amplifier capable of exceeding your legal maximum power by 3 db.
-
- (GR2.58, RIC- 25 p. 11-12)
-
-
- Q6: So a General class licensee can transmit phone on 3760 or even
- 14140 kHz? And a Novice can use a 2 meter repeater?
-
- A: Absolutely.
-
-
- Q7: But I heard that the FCC won't allow you to exceed your US
- operating privileges, even in another country.
-
- A: I personally called the FCC and was able to confirm that this is
- NOT the case. The FCC does not enforce Part 97 in foreign countries.
- Despite what you may have read, it is perfectly legal to use whatever
- privileges Canada allows you (see above) while you are operating a
- station in Canada.
-
-
- Q8: How do I identify in Canada?
-
- A: If you're operating under your US license, then you use your call
- "mobile" (if you are) or "portable" (if you're not), *followed by* the
- appropriate indicator:
-
- Nfld: VO1
- Lab: VO2
- PEI: VY2
- NS: VE1
- NB: VE9 (since Dec 1993; prior to this it was part of VE1)
- Que: VE2
- Ont: VE3 or VA3
- Mtba: VE4
- Sask: VE5
- Alta: VE6
- BC: VE7
- NWT: VE8
- Yukon:VY1
-
- On CW, RTTY, and such you just use a slash, for example, I would use
- "KG2S/VE2" in Quebec.
-
- The treaty requires you give your location by City and
- Province/Territory at least once per contact, but the Canadian rules
- make no mention of this.
-
- While the treaty requires English ID, the Canadian rules allow you to
- use French, too. A chacun son gout. (However, you are not limited to
- English or French during your contacts; you can use any language.)
-
- Of course, if you operate a Canadian station or get a Canadian license
- yourself, you use that callsign.
-
- (GR2.57.1-3, RIC-25 p. 12)
-
-
- Q9: What if I'm not from the US?
-
- A: You will have to contact Communications Canada (numbers below) and
- apply for permission to operate. If your country has a reciprocal
- agreement with Canada, your privileges (once licensed) will be those
- outlined in Question 3.
-
- If you, as a US licensee, want a Canadian license, you may be able to
- get it merely by passing a 26-question rules exam and giving a
- Canadian address. I know of at least one Advanced-class licensee who
- has done this with a Delegated Examiner. A Canadian station license
- carries an annual fee (currently about CDN$23), and license terms end
- 31 March of each year.
-
-
- Q10: I'd like to get a copy of the Canadian rules. What do I do?
- Where do I address questions if I'm in a "gray area"?
-
- A: I highly recommend getting a copy of the rules. They publish a
- number of circulars called RICs ("ricks") that you can order. They
- sent me these without charge. You can get them in French, too, of
- course ("CIR-25", etc.).

- CP> I just passed my technician exam and waiting for my license to show up in

- CP> made? (Of course, I
- CP> know I cannot transmit until I receive my callsign)
-
-
- Autopatches can work differently on different repeaters. My advice is to
- get in contact with the Control OP of the repeater(s) you wish to use and
- ask him/her how it works.
-
- Here in the Raleigh, NC area, we have *open* and *closed* autopatches.
-
- Open patches require no access code to use them and are available to
- anyone.
-
- Closed patches require an access code and are usually "closed" to all
- except the members of the club that sponsers the repeater. You are given
- the "code" when you pay your dues.
-
- One final note....
-
- Our club repeater(s), we have 2, one on 2-meters and one
- on 440, are of the *open* viriety but they both work just a little
- differently from each other but we will give out these instructions over
- the air to any one who askes. However as a Control OP of our repeater(s)
- and an officer of of our club, I strongly recomend you DO NOT try to
- access the autopatch whether it is open or closed "just to see if you can
- do it" until after your license comes in, you never know when records are
- being kept and tape recorders are going.

-
- You should also keep in mind that you are a "guest" on the system,
- even if it is an "open system". Don't just get on and use it as if you
- had a right to. Ask permission from someone in authority. You will be
- much more welcome by doing so. This also gives the person in authority

- First, let me answer the actual question since I have yet to see any
- reply on this one. Yes, there are HTs which come with NiMH batteries.
- The ones I have read brochures on are the Motorola Visor series HTs, they
- are small like the size of the new tiny ham HTs but NiMH is standard issue.
- They are available in high band VHF, UHF or 800MHz trunk.
-

- True but read others' comment about the down side too. NiCds memory effect
- is not as bad as it seems although it can happen at a very minor level.
-
- >highly desirable traits for a handheld. Thanks
-
- I'd want them for the higher capacity per weight/size and I am not
- too worrying about self-depletion since I mostly can charge them every
- night. The not so desirable side is higher price and that's why it is
- not in the ham market as standard issue first. Third party should make
- them but I've not seen them. Chargers (rapid) have to be different than
- for NiCds.

- First you have to determine the source of the RFI (computer, monitor,
- printer, cabling). Disconnect everything and start plugging in one
- unit at a time. If its cabling there are ferrite products you can
- buy to wrap around them. If its radiating directly through the
- enclosures, that's a problem. The next question is how is it getting
- into the rig. When the antenna cable is disconnected is the receiver
- clean? If so, is there a leak in the coax or is the antenna right
- over your head? Proximity is a killer here. It maybe be the best
- your can hope for is a reduction and not an elimination of this
- problem.

- I have my radio gear located practically next to my computer monitor. My
- computer is in a tower case and sits on the floor. When I still had a desktop
- system the RFI was terrible, so I went out and found an all-metal tower case.
- It's important that you ground the case when you assemble it - there is
- usually a lug provided for that. As for the monitor, few are adequately
- shielded with the exception of low-rad monitors.

- The real question is: What's this trash doing in this news group?
-
- Before you go off the deep end, remember the definition of trash. It is
- the same as weed. A rose is a weed if it's in the middle of the lawn. It's
- simply in the wrong place.
-
- I have nothing against this posting except that it has nothing to do with
- this group. There are other places for it, especially when it is lengthy.
