Reminder: Portable Ops Challenge, September 4-5, 2021

Leave a comment

If you’d like to participate in a contest that balances the playing field between fixed, high-power stations and QRP portable stations, you might take a look at the 2nd annual Portable Operations Challenge.

The POC will take place September 4-5 during three, 4 hour periods. The exchange is very simple: your 4 character Maidenhead Grid Square. You can even combine this event with a scheduled summit or park activation. 

This contest even includes prizes for the winners.

Check out the POC webpage for full details. I’ve pasted details from the POC page below:

PORTABLE OPS CHALLENGE

The Fox Mike Hotel Portable Operations Challenge is designed to optimize equal operating conditions for portable operating during a contest involving non-portable stations. The scoring allows and encourages regular home-based station operations to take part while offering a handicap-style scoring algorithm to be more equalized for portable stations. The approach is akin to the handicap index in the sport of golf. More difficult courses are scored with a higher slope value, indicating a greater challenge to achieve a normal par score of 72 on that course with a handicap of subtracting strokes for golfers who do not typically shoot as low a score as other golfers. A number of factors go into deriving the slope rating for a golf course but they represent the challenge that the course presents to each participant golfer and the golfer’s capability for playing the course.

The POC aims to make portable operations “on par” with more typical fixed-based operations while preserving the enjoyment of being in a new operating environment. Moreover, fixed-based operators can also easily participate in the action, challenging the handicapped-scoring for portable ops. Can the Super Station contester best the Little Pistol portable operation? If we use a scoring metric that reduces the advantages of fixed stations to that of pure radio sport operating, is there a chance that an efficient portable operator or team can come out ahead of the current winning contest station operators? That’s why this is called the Portable Operations Challenge!

THEORY OF THE CONTEST SCORING FACTORS

Several aspects of fixed (permanent)-station contesting can be stacked in the operator(s) favor when compared to most portable operations. One is the use of greater RF power output. Another is a permanent tower with directional, gain producing beams. A third is that it is easier to have multiple transceivers and operators, allowing for a “per-transmitter production” that yields superior scores. A fourth is the mutual attractiveness for fixed-station ops to work other fixed-station ops and ignore the weaker (especially QRP) signals. The addition of having the full force of Internet communications (when allowed), spotting sources, better ergonomics for operating positions, food/drink conveniences, and climate-controlled shelter all add-up to give “course advantages.”

While some portable operations (an example can be some large Field Day teams) can meet or exceed the advantages to contesting identified above, the vast majority do not.

Our scoring metric equalizes some of these advantages. Four factors are used in scoring each contest operation submission. These are the same regardless of whether it is a single operator or a team of operators, unassisted or assisted through the use of operation spotting. These include:

a. Kilometers-per-watt (KPW). Using the Maidenhead Grid Square, the distance in miles divided by the reported power output in watts for the reporting contest participant.

b. Fixed (permanent) vs Portable operation (favoring portable).

c. Mode of contact: Phone vs. CW vs. Digital (favoring phone over CW over digital)

d. Number of transmitters in use (points X 1/t where t = # transmitters)

The logic underlying this metric is as follows:

The KPW metric will tend to equalize power used as well as antenna gain. The km-per-watt is computed per-contact using the centroid lat-lon of the Maidenhead grid square exchanged during the contact. Favor goes to the greater miles-per-watt which equalizes to some degree the antenna gain, power, and point-to-point propagation conditions. The MPW is the basic contact score. Fixed (permanent) station operators have their resident setup which gives an advantage over portable ops, although a team could replicate a Field Day setting with portable crank-up towers, amps, generators, and so forth. Favor goes to the portable operator. The amount of this multiplier can be adjusted much as a competitive “tuning parameter” in future contests.

All things being equal in a QSO, phone is most challenging, followed by CW and then digital (especially weak signal modes like FT8). Favor goes to phone first, CW second, and digital third.

The more transmitters shape the number of contacts so more transmitters get increasing decrements in the points awarded, regardless of the number of ops. This emphasizes the per-transmitter production rather than just the amount of equipment and number of operators. We are experimenting with what seems appropriate discounts for the number of transmitters in simultaneous so as to render a more equitable competition, favoring sport over equipment.

Portable Operations Challenge

The final rules for the FMH Portable Operations Challenge are now posted on the POC webpage at foxmikehotel.com/challenge/. N1MM+ users, need to select FMHPOC as the contest and VKContest Logger users just POC.

The organisers wish all other contests taking place this weekend success and lots of fun – the bands will be busy again and we’re hoping propagation plays along.

We hope many amateurs give this new-style contest a go whether from a home QTH station or out portable.

Mark your calendars: The Portable Operations Challenge – October 3 & 4, 2020

Ridgeland, Mississippi— August 10, 2020 — A new contest has been announced that will level the competitive playing field between the Big Guns and the Little Pistols who operate a portable station. It’s called the Fox Mike Hotel Portable Operations Challenge. “The scoring metric is the distance-per-power metric with multipliers for portable operators and the difficulty of the transmission mode,” said Ed Durrant DD5LP, a member of the Steering Committee for the POC. “We are using kilometres-per-watt as the score for a contact. But those using a more difficult transmission mode such as phone will get a higher multiplier than those using the more efficient modes of CW and digital. Being a portable station will receive an additional multiplier, especially when contacting another portable station.” The scoring system is based upon the golf metaphor of the handicap index used to equalize the opportunity for all players to win when they have unequal ability and play on courses with varying levels of difficulty.

The POC is being sponsored by ARRL’s National Contesting Journal, the UK DX Foundation (CDXC), the Hellenic Amateur Radio Association of Australia and the South African Amateur Radio League. NCJ Editor, Dr. Scott Wright K0MD, said, “NCJ is very pleased to be an official sponsor of this contest event. It will encourage activity by operators who are “limited by real-estate,” and do not have a full-blown contest station. Events like this stimulate more interest in contesting and it will have an international scope to give chances to snare some new DXCC entities.” Don Field G3XTT, Editor of Practical Wireless magazine and highly experienced DX contester who is President of the UK DX Foundation, added “This is an exciting new contest event. I’m happy to serve on the Steering Committee and help in any way I can!” A highly competitive contest operator from Australia, Tommy Horozakis VK2IR, was very enthusiastic to join the Steering Committee to help plan the POC: “I’m really excited to be part of the team and can’t wait to get started.” Tommy VK2IR added that the Hellenic Amateur Radio Association of Australia was pleased to be an award plaque sponsor for the event.

The Portable Ops Challenge is the brainchild of Frank Howell K4FMH who says his portable ops team was the inspiration. “I hear many operators who get outdoors and try to dip their hands in a conventional contest say two things. They enjoyed the competition. And it’s a shame that the Big Guns dominate the realistic chances of winning. That’s simply the way it is in the vast majority of contests but it made my portable ops team think: is there a way to level the playing field? I think the Steering Committee consisting of both veteran DX contest participants and some of the best portable operators in the world has come up with something worth giving a go,” Frank K4FMH said. “I’d say the question is, whether the Big Guns can win using the handicap system that the Steering Committee has produced. With this scoring metric, it’s more about radio sport than radio gear. But we won’t know until many of the Big Guns enter the Portable Ops Challenge. We are building it but will the Big Guns come?” Only time will tell but the first POC is nearing it’s inaugural launch.

Scheduled for October 3 and 4, 2020, the POC’s rules and other relevant documents are located at foxmikehotel.com/challenge.
