• GA looks for States (51),• Provinces (13),• And DX.

– DX are not mults, but count as QSO Points

• Everyone else looks for GA Counties (159)• Rovers are “new” as they change counties• Mults are per mode, but not per band.• Points – PH=1 CW=2• See gqp.contesting .com for full rules and a list of counties and provinces

GQP

GQP• Operating Hints

• You send and Log: • W1AW 599 BIBB (or the actual county you are in)• GA Stations- Do not send GA as your location, always send a county.• You do not have to add any /M, /COBB, or other suffix to the call.

• You Receive and Log:• W1AW 599 CT -when working an out of state station• The location should be one of the 51 State or 13 Province abbreviations commonly used.• ARRL sections should not be used.• We do sort out "VE3" as "ON" and some other variations for Canada.• MD is separate from DC. • When working a DX station, log "DX" as the location, not the country prefix.• PA3ARM 599 DX -as an example of what you would log.• We do also check for slips here and try to fix them if we can.• • When working another GA station, Log the County abbreviation, not "GA"• NE4S 599 COBB - for example• If the station does not send the County, you can log "GA" as a last resort.• You will get credit for GA as a state multiplier worked when you log a GA county.• GA counties are not multipliers for GA stations, but do count for QSO points.• • This last item gives rise to the oddity that "GA" should not be in any of the logs for GQP. • Out of state stations and DX should sent their locations as in the examples above.• The list of Abbreviations and Multipliers is at http://gqp.contesting.com/Rules.htm• along with the full rules.

• Log all the dupes, it is faster and is sorted out in score processing.• • Do your best, the score process is very forgiving.

Alberta [AB] for (VE6, VA6) British Columbia [BC] for (VE7, VA7) Manitoba [MB] for (VE4, VA4) New Brunswick [NB] for (VE9) Newfoundland/Labrador [NL] for (VO1, VO2) Northwest Territories [NT] for (VE8) Nova Scotia [NS] for (VE1, VA1, CY9, CY) Nunavut [NU] for (VY0) Ontario [ON] for (VE3, VA3) Prince Edward Island [PE] for (VY2) Quebec [QC] for (VE2, VA2) Saskatchewan [SK] for (VE5, VA5) Yukon [YT] for (VY1)

GQP

• Rovers may use a driver and be Single OP– Rover must do all operating and logging

– Safety first, some laws may apply here

• Rovers are not broken out by power – Run as much as you can

– All are grouped together for awards

• A rover may also submit a separate home log– As long as the home county is not in the Rover Run Log.

– Saturday day on the road, Sunday at home- not a bad plan

• Fixed stations are grouped QRP/LP/HP– 5W/150W/1500W

• Fixed Stations may split into CW and PH – But not Mixed also, Qs are entered only once

Now That’s a Rover!!3 el A3 with 40M kit

(I wish I had it back!! NE4S)

GQP• Rare Counties• It seems that the one we miss is the "rare" one.

– It is hard to say what misfortune befalls the rovers that causes them to miss one, – or why no fixed station got on the air from some counties.

• At http://gqp.contesting.com/RareCounties.htm is a historical record of counties we have missed in recent years.• A good route would be one that visits a few of those counties that had 0Q's or have a low ham population as part of a trip

you would find convenient and enjoy.• We try to coordinate activity of Rovers and Fixed operation through KU8E. Please let him know of your plans at

[email protected] as soon as you can.• Middle and Southern counties “tend” to be missed.

– Terrell was the only missed county in 2008!– Echols, Atkinson, Wilcox, Seminole, Berrien, McDuffie, Glascock, Hancock, – Lincoln, Charlton, Jasper, Jenkins, Screven, Burke, Brantley, Elbert, Hart, – Franklin, Jones, Putnam, Dade, Baldwin, Pickens, Liberty, Stephens, Richmond, – and Columbia have been missed in 2007 or 2006.

• Put some rovers on the road• Get your club and county members active

DXing and Contesting from Your Car by Jeff Clarke KU8E

Why should I setup a mobile station in my car ?

• Have the ability to get on the air if you don’t have a home station.

• It’s fun to have a mobile station in the car to pass time on long car trips.

• Operate as a rover in contests such as State QSO Parties or VHF Contests.

How do I get started ? Step #1

• Pick a radio.

Installing your radio in the car.

• Use a fused DC power cord

• Don’t use the cigarette lighter adapter.

How do I get started ? Step #2

• Choose an Antenna.

Mobile Antenna Mounting Tips

• Choose the right type of mount for your antenna.

• Take the time to properly ground your antenna.

Mobile Antenna Fundamentals

Some Basics

When an antenna is shortened from it's naturally resonant length at the frequency of interest, the feed point becomes capacitive and it becomes necessary to add offsetting inductance in the form of a loading coil. This restores the resonance of the antenna. Unfortunately, the additional inductor also has resistance that adds loss to the antenna. The resistance in the coil eats up your power and you are not going to be as loud as you would be if the coil loss were not present.

The more that you shorten the antenna, the larger the coil that you need to use. The larger coil has more resistance and eats up more of the power. Mobile antennas are usually pretty short, require large coils and hence have large losses. This loss resistance is also seen at the feed point and is partly responsible for making it easy to match this shortened antenna to the 50-ohm feed line and radio.

The impedance seen at the feed point is made up of the radiation resistance, coil loss and ground loss. The radiation resistance of a full size vertical antenna is about 35 ohms. As the antenna is shortened the radiation resistance goes down quickly but the other losses are still there or even increase.

Mobile Antenna Fundamentals If you have a 72-inch, 20m-whip antenna and you are measuring an SWR of 1:1 that

means that you have a feed point impedance of 50-ohms. The true radiation resistance of your antenna is somewhere near 3-ohms. That means that you have a loss in your system of 47-ohms (50-ohms minus 3-ohms) and a radiation efficiency of about 6 percent (3-ohms / 50-ohms). So, if you have a 100-watt transmitter in the car, 94-watts are being used to heat the air and only 6-watts are being used to communicate! The other 94-watts are used up in the loading coil and ground system

Radiation Resistance of shortened Mobile WhipsHeight (in.) Freq. (MHz) Radiation Resistance(Ohms)72 1.8 0.0572 3.5 0.1772 7 0.6972 10 1.4272 14 2.7772 18 4.5972 21 6.2472 24 8.1572 28 11.10


Mobile Antenna Fundamentals

How do we reduce the loss in the Loading Coil? Basically, we try to use the one with least inductance and resistance that we can still

get to resonate the antenna. One way to reduce the size of the required coil is to install what is known as a capacity hat. A capacity hat can be thought of as an extension of the Marconi antenna design that adds horizontal elements to the design of an otherwise vertical antenna to add length. If the capacity hat is designed correctly the currents in the horizontal sections of the hat offset one another and preserve the vertical polarization of the wave radiated by the antenna.

The base impedance of the antenna will drop to about 16-22-ohms when you increase the efficiency of the antenna. Any matching problems will probably be taken care of by your rig's antenna matcher or a more efficient way would be to use a small matching transformer.

How much did the efficiency increase? If the base impedance was reduced from 50-ohms total to 20-ohms total when the

actual radiation resistance of the antenna is really 3 ohms you will have gone from 6% efficiency to 15% efficiency. More than doubling the RF power coming out of your antenna.

State QSO Parties

The Georgia QSO Party

Rovering

Just about every State QSO Party has a Rover category.When you operate this category you are allowed to workeveryone you had worked in a previous county again.

RoveringBecause you can work everyone again from a new county you can generate some big QSO totals. K1TO has broken 3000 QSO’s in the Florida QSO Party. K5KG and W4AN (KU8E/K4BAI) usually at least 2000 + QSO’s in the Florida QSO Party. K4BAI/KU8E usually have nearly 2000QSO’s in the GQP.

RoveringSome rover participants will have a simple setup in the car and just log on paper. The more serious operations will use computer logging and might have a GPS in the car to indicate when they are in a new county.

RoveringRemember earlier when I mentioned how inefficient the typical mobile antenna is ? Here is K5KG and VE7ZO’s solution to that problem for 20 meters and up. They tow a trailer with a Force 12 vertical dipole mounted on it.

County Hunters

Many of the participants in state QSO parties areCW county hunters. They are regulars in just aboutevery QSO party.

You can usually find them on 14056.5, 10122.5,7056.5 and 3556.5.

KU8E Rover Setup

KH6DX/m

KH6DX/mI have worked 288 countries mobile. I have worked over 100 countries on all bands including 160M. On 160 Meters I have worked and confirmed 104 countries so far. I have my 5BWAS/m +160M and WAC/m on all bands 160 to 10M.

Needless to say that I enjoy mobile very much. I have entered many contests with the mobile and have picked up lots of new DX that way. I have even won a few of them for my area. I know I will never be able to compete with the big guns but I can make a close second at times. It’s FUN.

My new antenna is a N9JMX ([email protected]) 4" Screwdriver called The Predator. It uses a 4” dia by 5’ Stainless Steel pipe for the base. The coil is wound on a piece of Special High Temp Fiberglass and is about 2’ long. There is a screwdriver motor at the bottom of the pipe which drives a threaded rod. On top is a CB whip with a couple of tophat wires about half way up the whip. The top hats are actually wire loops and the top of the whip is bent to form a loop as well. This is done to help eliminate corona discharge on the lower bands. I can control the antenna resonance from the drivers seat by energizing the motor which drives the coil in and out of the copper tube. There is finger stock on the top of the copper pipe that makes contact with the coil wire which is #10 tinned copper wire. As the coil goes into the copper pipe those turns are shorted to the pipe in effect eliminating them from the circuit. For 160 Meters I have an aux coil I mount between the existing coil and the top whip, It is wound on a piece of 6” by 6” PVC and is rather high Q. I fine tune to resonance using the lower coil.

I have a box mounted at the base which has all the relay control and matching vacuum variable which is also motor controlled. It is about 10 to 1000PF and runs from the antenna base to ground. It is used on the lower bands to get a good 1:1 match. I switch it out on 30M and above.

Another part of the antenna which most people don’t consider is the ground system. I have run a copper pipe from the front to the rear of the truck under the chassis. The antenna ground and almost all truck chassis parts are run to this ground bus using large copper braid. Thing like the chassis frame, the exhaust system, the engine,enders ,bumpers etc. are all bonded together by this buss. It really helps to reduce noise and lowers the loss resistance of the antenna. This helps a lot because on top band this antenna has a radiation resistance of less than 2 ohms. I figure the antenna is about 10% efficient at best. I make up for that with a really good location and high power . For the pacific area I drive up to near Santa Barbara, about 45 miles away and park right near the water. I have a really great path over salt water to everyplace west. For the other areas I go to the top of a hill near my QTH where the noise level is very low and I can see in all directions. I have worked into Europe and Africa from that location several times. Its also good into South America as well as stateside. My goal has been to work DXCC on 160 Meters Mobile. It has taken several years but now I'm finally working on the second 100 countries.
