Experimental Contest Day Needs A Sponsor

Content and inspiration courtesy of ARRL Contest Update edited by Ward Silver, N0AX.

I'm surprised, given the scholarly examination of RadioSport rules, that Experimental Contest Day did not receive its appropriate level of examination. I have not read a scant word. Ward submitted the following questions, "[W]hat if multipliers "evaporated" over the course of a contest. [W]hat if the idea was to sustain "coverage" of a multiplier?"

His concept is based on the board game, Go, known for its rich strategic complexity despite simple rules. Ward proposed a variation on the board game wherein grid fields (CN, EM, FN and so forth) are covered for a discrete amount of time. Furthermore, when the grid field decays, an operator must re-cover the multiplier. Hypothetically, at any given moment, an operator's grid field is a needed multiplier while an operator must sustain his/her concurrent grid field.

One may consider, if the grid field is allowed to decay, then an operator cannot re-cover the multiplier? Points are awarded for active grid fields at the end of the event.

Ward further proposed covering most if not the entire spectrum of allocated frequencies. His concept is the upper most reach for ham radio related activity. The appeal of such an event slices through clustered interests and turns on the power button for the entire community at all levels.

Proposed Benefits.

  1. Increase understanding of propagation properties in relationship to ionospheric functions.
  2. Foster operator skill development.
  3. Promote station engineering across all levels to meet event demands.
  4. Performance measurements relating to skill development and decision making processes.
What a demonstration of amateur wireless communication where the entire or nearly entire allocated spectrum is operationalized while maximizing activity for a given period of time. Experimental Contest Day needs a sponsor.

Propagation Planning

RadioSport's Wikipedia project, Contest Compendium, is a primer for entry to re-entry level operators like myself. Carl, K9LA suggested the following when planning for propagation during an event.

  1. Know the contest.
  2. Run Predictions for the Paths for Your Most Important QSOs.
  3. Be Flexible During the Contest.
An excellent, well written Wikipedia knowledge unit. Propagation planning for contests (link).

Explore WebSDR

Worked All Europe (WAE) DX CW is global with popular appeal, perhaps, one if not the big time favorite of Eu-ops? My antenna system rarely pulls out a transmitted signal ranging from the Arctic regions of Radio Arcala to the southern tip of Africa. Basically, my confirmed Q visualization map revealed an ionospheric abyss beyond the Atlantic seaboard.

However I wanted to experience sight and sound of WAE this weekend and what is my solution?

WebSDR and I want to examine an idea related to Xtreme Category. My station configuration is one high frequency (HF) transceiver (Yaesu FT-100), one wire antenna system (Center Fed Doublet at 33-feet), and one antenna tuner. Ultimately, an entry level configuration, with limited real estate for antenna system expansion.

RadioSport operators like looking to the horizon for opportunity and potential for station expansion. Additionally, the hunt is always on for improving the dB quality of one's transmitted signal. Budgetary constraints also drive innovative methodologies that is, looking at the problem from a different angle.

Different Angle.
>Yaesu FT100 + VFO A + VFO B = Single Operator 2 VFO (SO2V).

>SO2V limitation 1 transmitter + 1 receiver on any given band at any given time.

>VFO B + software controlled radio (SCR) + WebSDR = Availability of second receiver minus the expense of a second transceiver.

>WebSDR + SCR + VFO B x typing frequency into program command line = Availiablity of second receiver facilitating next level SO2V within a CCR and/or HOA defined community.

My thought process for example, if I'm utilizing a geographically equivalent or near equivalent WebSDR, functionally, I can search another band for multiplers and utilize program command line function.

>Type frequency into command line (SCR) = cycling between VFO A or B for efficient SO2V operation x WebSDR.

I observed Level 1 signals on the waterfall display or spectrum analyzer on 40m last night and quickly discerned a difference. Level 1's appeared brighter and consumed additional bandwidth on the waterfall unlike other signals. Additionally, filters are available, waterfall settings, and an s-meter compliments of software instead of hardware.

Benefits of RadioSport WebSDR for low power, low profile operators may include the following?
  1. WebSDR is not geographically specific however regional coverage facilitates searching for an available CQ frequency.
  2. A pair of active receivers on two bands, simultaneously.
  3. Switch to multiplier using command line function within the contest logging program like N1MM Contest Logger.
  4. Monitor propagation changes as the RadioSport event progresses.
  5. Confirm maximum usable frequency charting.
I'm entertaining an idea without ramping up cost for hardware. Why not, for the sake of experimenting, utilize computer speaker output plus transceiver speaker output, without headphones? Then gradually build-in the hardware necessary to feed speaker outputs into a set of cans. Feasible? Yes. Fatiguing? Probably. However I can test my idea during a State QSO Party.

Is this a good fit for Xtreme Category? I'm using off-the-shelf technology, readily available parts, and testing an idea. One can only explore and discover.

P.S. I'm listening to K7UEB Walla Walla University WebSDR at the moment.

This Weekend In RadioSport | Log Eu

RadioSport Eu | WAE DX CW.
Worked All Europe (WAE) DX CW storms RadioSport arena this weekend. Are you ready for the QTC challenge? A QTC is a minimum block of 1 Q and a maxium block of 10 Qs that includes the following data; time, call sign, and reported serial number. This caliber of exchange requires absolute concentration with bonus dividends. Every successful QTC exchanged counts as 1-point for sender and receiver. However, if any of the data is miscopied, then zero bonus for the series.

WAE DX CW log submission deadline changed according to the current edition of CQ Contest Digest. On the other hand, I'm wondering aloud, will a RadioSport USA contest sponsor consider a similar QTC style exchange, perhaps, grid square and serial number?

Why Is Xtreme Category Feared?

What is up with snark? What is up with slamming the door in the face of imagination and possibility? What has happened to can-do spirit and let's get the team behind this one? CQ World Wide announced Xtreme Category for the purpose of innovation, instead, a greater percentage of commentary is snarky at the current Xtreme poll. That's disappointing in my logbook.

Why is Xtreme Category feared?

What a fantastic opportunity at excelling and I'm looking around the shackadelic thinking about future possibilities not limitations. One operator suggested extremely small antennas, well, what type of antennas are inside one's mobile device? Think. Think, about the one who invents an extremely small antenna that functions like a dipole for those operating within CC&R and/or HOA defined communities. Has one thought about patent possibilities that develop as a result of the Xtreme Category?

Fear stinks like a pile of too much information. Intuitively, Xtreme Category, is feared because it upsets status quo. A familiar, routine that instinctively (n = 124) or 68% of the poll respondents safely answered no. However, (n = 26) or 14% answered an innovative, let's take on the challenge and create something, yes.

Xtreme category is not about right now instead it is about long term vision and innovation, in other words, change. The domain of wireless communication is moving ahead at Internet speed and commerce. On the other hand, another respondent waits for an uptick in Cycle 24 to quash Xtreme Category relevancy, totally missing the potential. An uptick in sunspots is not solving our relevancy dilemma when competing against an array of entertainment devices nor will sunspots stop the march of progress.

I, for one want to meet those 26 innovators because they are not afraid.
