Simplex Saturday Report |

GBARC's first Simplex Saturday was held between noon and 1:00pm, Saturday 30th April 2022. The following stations checked in:
- VA3KOT John (NCS)
- VE3WI Dave
- VE3OZW Richard
- VE3RQY Greg
- VE3RWY Rob
- VE3PQ Paul
- VE3NBJ Norm
- VE3VCG Marvin
- VE3JMD Jim
- VE3BQM Bernie
- VA3TS Tom
- VE3FP Adam
An honorable mention should also be made to VE3DGY Doug who attempted to check in but experienced equipment difficulties.
Net controller John VA3KOT was stationed in the parking lot of Inglis Falls Conservation Area just south of Owen Sound operating 50 watts into
a collinear VHF vertical antenna mounted on a truck hitch.
What Was Learned?- Communications between Inglis Falls to Owen Sound and points in Georgian Bluffs were clear and strong.
- Communications between Inglis Falls and Port Elgin (VE3WI) were challenging. John VA3KOT's signal was reported to be noisy in Port Elgin but signals from Port Elgin into Inglis Falls were loud and clear.
- Communications between Paisley and Inglis Falls revealed a surprising result. VE3VCG was stationed at the Paisley repeater site and comms were noisy and difficult - until Marvin re-oriented his truck then it was 59 both directions. Marvin's mag-mount antenna was off-centre on his truck roof and that seemed to be enough to dramatically change signal strength.
- The NCS base station is recommended to use an antenna elevated on a pole
- The NCS base station should check for local electrical noise interference. A hydro pole transformer was suspected to be the source of noise at Inglis Falls.
Thank you to all who participated. The exercise should be repeated at some point in the future to learn more about unexpected practical difficulties that are to be encountered in the field.

Topic: Happy 230th birthday Samuel Morse.
What is a "Bel"? Would you consider buying an antenna with a gain of 1 Bel? (Trick question; antenna gain should be stated in dBi - i.e. relative to an isotropic antenna with unity gain).

Simplex Saturday
12:00 p.m. - 1:00 p.m.
Sat., Apr. 30, 2022
GBARC will be holding its first Simplex Saturday this Saturday, April 30th 2022.
Purpose:
1. To test VHF communications readiness in an emergency if our repeaters become unavailable
2. Well, alright, to have a bit of radio fun
Frequency: 146.520 MHz, no tone. Yes, this is the simplex calling frequency. Hopefully other hams monitoring the frequency will check-in. We will QSY if asked to do so.
This will be an informal directed net. NCS will be John VA3KOT who will be operating portable using 50 watts into a 2m omnidirectional collinear antenna.
Short notice? Yes, emergencies tend to happen that way!
Please join us.

Basic with honours qual and the use of amplifiers |

There is little that causes more confusion than ISED's rules regarding amplifiers and the basic qualification with honours.
Actually the confusion comes from the use of different ways we use to describe the same maximum power. Referring to RBR-4 below lets look at section 10.1 (b).
10.1(b)i says 560w peak, 10.1(b)ii says 190w carrier...these are in reality the same power output. To measure PEP output one would need to look at the signal on an oscilloscope or equivalent, across a 50 ohm load. This will require an instrument that can withstand a signal of approx 475 v p-p. Luckily we can also use a simple rf wattmeter and using our radios tune function, set the transmitter(exciter) drive to produce a 190watt power level on a wattmeter installed at the output of the amplifier, again into a 50 ohm load.
BE AWARE ---those with the basic and honours qualification are not in compliance with the regulations if you set the amplifier output to 560 watts using a wattmeter into a 50 ohm load.
10.1(a) is indeed an alternative, however few are capable of performing the measurement, it can be dangerous due to the power involved and would likely require the defeating of a safety interloc.
RBR-4 — Standards for the Operation of Radio Stations in the Amateur Radio Service
https://www.ic.gc.ca/eic/site/smt-gst.ns....html#p3.1
10. Restrictions on Capacity and Power Output
The transmitting power of an amplifier installed at an amateur station shall not be capable of exceeding by more than 3 dB the transmitting power limits described in this section.
10.1 Amateur Radio Operator Certificate with Basic Qualification
The holder of an Amateur Radio Operator Certificate with Basic Qualification is limited to a maximum transmitting power of:
(a) where expressed as direct-current input power, 250 W to the anode or collector circuit of the transmitter stage that supplies radio frequency energy to the antenna; or
(b) where expressed as radio frequency output power measured across an impedance-matched load,
(i) 560 W peak envelope power for transmitters that produce any type of single sideband emission, or
(ii) 190 W carrier power for transmitters that produce any other type of emission.
The next bit of english which causes confusion is as follows.
Frequently asked questions
https://ic.gc.ca/eic/site/025.nsf/eng/h_00006.html
Technical
1.I am the holder of an Amateur Radio Operator Certificate. May I install and use a RF/Linear Power Amplifier with the operation of my station?
As per section 10.0 of the document RBR-4: Standards for the operation of radio stations in the Amateur Radio Service, the holder of an Amateur Radio Operator Certificate may install and operate transmitter equipment capable of producing an RF output of no more than twice (3dB) that authorized by their certificate . (Regardless, the operator MAY NOT exceed the maximum RF output levels authorized by their certificate).
This does NOT mean you can now set your amplifier to 380 watts rf output or 560 x 2 = 1120 watts and still be compliant. This part means you cannot USE an amplifier which can do this. You are limited to a amplifier that can output 380 watts max but you are still limited to 190 watts max actual power output according to your qualification.
You will find that few amplifiers meet this requirement. Even an Ameritron ALS-600 still can put out 600 watts which is 220 watts higher than your qualification permits. Any amplifier which was built from a kit which includes ALL heathkit devices are not allowed either as you are limited to "commercially made" equipment.
So whats the solution
Study for and obtain your advanced qualification
Want to run 200 watts....buy a 200 watt transceiver such as the Kenwood TS480HX, among others are good examles of rigs the basic with honours ham can use.
etc etc the following is included just for completeness
RIC-3 — Information on the Amateur Radio Service
https://www.ic.gc.ca/eic/site/smt-gst.ns...01008.html
4.5 Privileges and restrictions
Privileges and restrictions can be found in the Radiocommunication Regulations and in RBR-4. A brief summary follows.
4.5.1 Basic Qualification
The following privileges and restrictions are applicable to the Basic Qualification:
-access to all amateur bands above 30 MHz
-use a maximum of 250 watts DC transmitter input power
-build and operate all station equipment, except for “home-made” transmitters (“build” in the context of the Amateur Radio Operator Certificate with Basic Qualification is limited to the assembly of commercially available transmitter kits of professional design)
-re-programming of radio equipment to operate in the amateur bands if this can be done by a computer program (note that no physical modifications to the circuitry of the radio are permitted)
-operation of cross-band repeaters
-operation through a repeater established by an amateur with the Advanced Qualification
-no remote control of fixed stations permitted regardless of medium used for control (“remote control” is the ability to indirectly manipulate the technical parameters (i.e. bandwidth, emission type, output power, etc.) of a radio by means of some intermediate medium; operation through a repeater is not considered to be remote control)
In addition to the above-mentioned privileges and restrictions, the Basic Qualification with Honours (i.e. a score of 80% or above) also allows access to all amateur bands below 30 MHz.
How do you know what qualification a ham has....
That's easy, go to this ISED website and type in that persons callsign, when the page returns click on their callsign, their qualification will be displayed.

Of Course, you can ask questions to ISED yourself, here is their email address in Sudbury

APRS Voice Alert |
Posted by: Richard VE3OZW - 2022-04-18, 09:08:31 - Forum: VHF Digital
- No Replies

For those of us (VA3TS, VE3FP, myself, others?) that run APRS on our mobile rigs, do you operate setup for voice alert? I have been operating for APRS voice alert for a couple of years, and I think due to the lack of radio capability in our area, I have not heard anyone. Not that we would be able to talk 2m simplex, but I am simply curious if others have voice alert active while mobile.

New CW mini contest will be added to the popular CWT and SST weekly contests.
The new weekly MST (Medium Speed Test) 20 - 25 wpm starting May 2nd with the same rules as CWT's except the exchange will be Name & Serial NR.
This mini Test should be fun if you find SST slow and CWT fast, MST should fill the gap.
For more info check outh https://internationalcwcouncil.org/mst-contest/
Hope to hear you on the new MST.

Weekly Georgian Bay Amateur Radio Net
Wednesday 13 April 2022 @1900 EDST
Net controller Marvin VE3VCG, QTH Paisley
Note: Due to changes to the net controller schedule created some confusion as to the scheduled net control operator for the GBARC Club net for this date. The location of the published schedule was taken off the website and moved to the newsletter. However because the newsletter for April is not yet available, the net controller rotation schedule was also not available. When there was apparently no net control operator on the air at 19:00 local, Marvin VE3CVG signed on as the net controller for this weeks club net.
Topic: “On air amateur operator etiquette.”
The topic was suggested by Larry VE3QIO
