Blog ImageThe RSGB has presented revised rules for their VHF contest program. They state the following:

The RSGB Contest Committee has revised the VHF General Rules relating to the use of the DX Cluster and other spotting/chat networks (including internet facilities for example ON4KST) in RSGB VHF and UHF contests.

The revised rules are listed below:

4i. The active use (posting messages, arranging skeds, self spotting etc) of the DX Cluster and other spotting networks (including internet facilities for example ON4KST) to assist an entry to a contest on 6m, 4m, 2m and 70cm is banned in all RSGB contests with the exception of three IARU Region 1 co-ordinated contests (50MHz Trophy in June, 144MHz Trophy in September and 432MHz to 248GHz IARU in October) and the 144MHz Marconi contest in November where permitted by the IARU rules for these contests. You may spot a DX station as long as your operating frequency is not given.

4k. All information must be copied off air at the time of the QSO and on the band in use. Databases must not be used to fill in missing information. The DX Cluster, talkback channels etc must not be used for passing or confirming any contest related information.

These revised rules take effect from midnight 30th April 2007.”

These are excellent rules, the RSGB should be commended for taking such actions to clean up bad operating techniques!

Now, take a close look at paragraph 4k:

“All information must be copied off air at the time of the QSO and on
the band in use. Databases must not be used to fill in missing
information.”

This is brilliant! The paragraph makes is absolutely clear that QSO’s made with the JT65 Deep Search (DS) module are not considered as valid. Because this is exactly what DS does, it automatically fills in information that has never been received via the RF waves!

Furthermore, it never shows the operator what it actually has received, so regardless of what the inventor of Deep Search (K1JT) says, there is no operator control over such a communication method.

The computer matches traces of info with database info, to print full messages. It is printing the messages after going through an extensive guessing process where the operator has no effect on the output.

Anyhow, these new rules immidiately started a debate where JT65 users defend their Deep Search toy, even saying that it complies with the RSGB rules…

See what our good friend Bernd, DF2ZC had to say:

Oh how strong I wish some people would finally understand that the DS decoder DOES NOT FILL IN MISSING INFORMATION PARTS such as missing letters of callsigns but tells the program which possible callsign combinations to search for in the noise… the permanent repetition of incorrect statements doesn’t make them correct statements.

Take a minute to analyze what he just said….
To me it is quite obvious that Bernd has not at all grasped the functionality of the Deep Search module.

Facts are the following:

The DS module will print 100% of a 56 bit message (calls), after having received 14 bits or less, i e <25% of the message. It uses a database on the computer to get the missing information.

If that is not filling in information from a database, WHAT IS?????

I am so glad we CW operators have no problems with this, we just copy the calls and the reports in full, and log the contact as a good one!

CW is King!!!!
