Random numbers contests




UKEICC Random numbers contests   (scroll down for Information)


Results - 2nd October 2017 Random Numbers contest - CW

Thanks to everyone who supported our 'trial run' CW Random Numbers contest. Activity was slightly higher than in the SSB leg - remember these are 'trial runs' of the concept so we never expected a large number of entries.  We intend to run two more trial runs in early 2018, after which we will decide if the format is a viable one. The UKEICC team are not afraid to try something new, rather than saying 'that won't work' without trying it!  Positive thinking is our motto!

Well done Graham G4FNL on the highest score in this CW event, as well as the previous SSB event, and to Nigel G4S (G3TXF) for the highest score in the Checklog (sequential numbers) section.

See the Soapbox comments below.                                 73 Chris GM3WOJ, Paul EI5DI - Adjudicators.

Soapbox comments :

More fun than the SSB version! -- EI7GY

apologies to some contestants - mixing up run mode with s&p mode otherwise a good learning experience -- G0MDR

Good format pity about the low turnout SD worked FB -- G3KNU

Just a little checklog. Deliberately entered with serials from 001 which claims is OK but most seemed confused and asked for repeats. Although a novel idea I don't think I will enter again. -- G3YMC


Sorry but only could come for the last 20mins. Think I goofed up with random numbers but only intended to give a few q's away after such a late start. Hope a few more come on in the future. The random ser number exchange makes life interesting. K3 and N1MM+ with low 80m dipole. -- G4BYG


Enjoyed the new format quite a challenge! Hope I didn't make too many errors! 73 Phil G4NVR -- G4NVR

Let's hope more take part next time. -- G4OGB

Sorry, still no RANDOM Number generator yet! -- G4S

Seemed to be more participation than in the SSB leg. First time keying the TX directly from the keyboard and it seemed to go ok - which is just as well 'cos I couldn't get the key to pass through!!  Getting there slowly!   Enjoyed the event! -- GM3ZDH

Band condx dire but enjoyed this contest very much with random number exchange. Hope to seemore of this kind of test in tefuture. -- GM4OSS

Failed to set up sd with ic7300 but managed to set up flex 6300 with winkey simulation. The realised the contest had started as 19z not 20z! Low activity but interesting and nostalga trip with SD hi -- GW9J

SD worked just great thank you Paul Sometimes thrown by stations sending 599 before number Really enjoyed the format -- M0RBG

Great fun - prefer random to sequential serials. -- M4J

A great concept for a contest and it certainly makes you concentrate. -- M7R

Results - 25th September 2017 Random Numbers contest - SSB

Thanks to everyone who supported this trial run SSB contest, especially given the relatively short notice about the event. It was fun but was a long one hour here in the GM3WOJ shack - I am sure you felt the same. The QSO rate was low and 80m was full of the usual European nets, noise, etc this evening. I think most entrants liked the 'random numbers' concept - an interesting operating and logging test - we just have to encourage more people to take part in any future events.  Please send any comments or suggestions to This email address is being protected from spambots. You need JavaScript enabled to view it. 

The UKEICC team feel that wider publicity for the CW trial will help increase participation - please tell your friends about this.  We will assess the longer term viability of this contest format after the CW trial run on 2nd October. The next pair of trial run contests will be in January or February 2018, by which time we hope N1MM+ and other contest logging software packages will also support this new format.    

Congratulations to Graham G4FNL on the top score, achieved by extracting every conceivable form of 'serial number' from stations that called him!

Thanks to our UKEICC software expert for creating the new Adjudication software which is being used for the first time this evening.                   

Reminder - the next contest in the UKEICC 80m series is on CW this Wednesday - 27th September

Got the time wrong but getting set up I heard EI5DI on the frequency I had planned earlier to use so figured he must be right. Few stations on but this is a trial. Some operators were very fast with their numbers. It's quicker to give it slowly than have a station ask for a repeat. -- EI2KA

The 4-digit number format seems to work nicely. It's just a pity that activity was low. -- EI5DI

I like the format it's a welcome change Needs to be supported by other popular logging programs to make it viable -- EI7GY

low activity -- G2AA

Great to have a new format for a change! Poor turnout though so maybe not so popular. Hopefully the cw session will generate greater interest? -- G3SWC

I've always liked the random number idea as I feel that the challenge of a contest should be about exchanging real information correctly under adverse conditions.  I'd be even happier if it was a random 8 bit alpha numeric sequence! -- G3UUT

Panic computer seized up could only work one qso. could not cure and had to put SD 1916 on another comput so lost 17 minutes. It was fun but very slow with few operators. Used SD as usual which worked ok on another laptop. -- G4DDX

Good fun. Very different. SD worked well even if it was just 8 QSOs! -- G4DRS

See my previous BOUNCED entry! -- G4S

Could do with a headset microphone for this one! Enjoyed listening to FNL getting people's dates of birth out of them - but it worked! -- GM3ZDH

Just the final few minutes after Cwops morse lesson -- GW4J

Should have read the rules more before the start but rushed into shack at 1900z and just started with wpx ssb template in n1mm. Gave out rs and then seq serial number and then halfway I started adding 00 to the sequential number hi hi - assume all entries I sent are correct. Hope n1mm supports it ready for cw as I don't want to mess with other software. 73 Steve -- GW9J




These two 80m contests (one hour on SSB and one hour on CW) are 'trial runs' - the UKEICC team want to find out if this format is likely to be popular with contesters before proceeding further. *Your* support is needed if they are to become a longer-running series of contests.

SSB - Monday 25th September 2017 - 1900-2000z       3600-3650kHz

CW - Monday 2nd October 2017 - 1900-2000z            3520-3550kHz

The concept is one that has been around for years, but not fully developed by any of the contest sponsors (as far as we know). Instead of a sequential serial number, your contest logging software generates a 4-digit pseudo-random number, in the range 1000 to 9999, which you send to anyone calling you when you are running, or to any station that you are calling when S&P. In turn, they send you a pseudo-random number which you log as the received exchange. Sending of RS(T) is optional.

Paul EI5DI has already added these contests to his SD software - see the information below. If you want to participate fully in these trial runs, we suggest that you install SD, V19.15 or later. (Note - for the CW event, use of a WinKey with SD is recommended, as smooth CW cannot otherwise be guaranteed) Other contest logging software writers have been contacted, but will take longer to implement a suitable template. SkookumLogger by K1GQ (for Mac OS) now also supports these events - see below.

You can also participate by using your usual contest logging software, sending sequential serial numbers, but logging sequential or random numbers from other stations. One suitable template would be CQ WPX (SSB / CW) with serial numbers starting at 001. These 'non-random' entries will be treated as Checklogs, but will be very useful to judge support for this format and will be listed in a separate table in the Results. Note - the adjudication software will deal with any logged number i.e. 1,2,3 or 4 digits that you log.

These contests will be an interesting and challenging test of operating skill and logging accuracy.

One unavoidable 'down side' of this contest format is that someone listening to the event without having any prior knowledge will not be able to participate. (This is not the case with our UKEICC 80m contests which have the instantly recognisable 4-character QTH locator exchange)

For these trial run events, there are no sections/categories (QRP/LP/HP, Assisted/Unassisted etc) and no penalties for logging errors (other than the loss of that QSO point). In future events there would be categories and penalties for inaccurate logging. Scoring will be 1pt/QSO.  Note : SO2V, SO2R and networked PCs cannot be used for these trial runs, but are definitely included in future plans.

Cabrillo logfiles should be uploaded before 2100z on the day of the contest via the UKEICC log submission robot. (Select 'Random Numbers SSB Contest' from the pull-down menu) Adjudication is then done automatically (using a new specially-written software module) and the Results will be posted on this website as soon as possible after 2100z.

The UKEICC team hope to expand the random numbers concept in future events - there will be two more 'trial run' events in early 2018.

Approved loggers :-
1.    SD by EI5DI - from www.ei5di.com - V19.15 or later. The relevant options are "UKEI Random, CW" and "UKEI Random, SSB". These are free and unrestricted options for these two trial run UKEICC Random Number contests - there is no need to register and no key file is required. The manual is SD.PDF (17 pages), included with the installation files.

2.   SkookumLogger by K1GQ - version v.2.1.12  (Mac users Download from here.  Users should create their log using UKEICC Random from the Regional section and, in addition with this version of the program, perform a Reset Log command from the Log menu before logging their first contact - this will ensure the random number to be sent for the first QSO is correct.  (This initial reset won’t be necessary in v2.1.13 which won’t be released until after the first trial events).
