[CQ-Contest] "Contesting Secrets" Presentation - 2BSIQ Two Bands Synchronized Interleaved QSOs

[José Nunes CT1BOH]

Hi

In the footsteps of N6TJ's most valuable legacy - Contesting Secrets - I
made a presentation to CTU - Contest University Italy about 2BSIQ Two Bands
Synchronized Interleaved QSOs.

This 49 slide presentation explains in great detail, CT1BOH's journey into
2BSIQ - Two bands Synchronized Interleaved QSOs.

There are nine sections. The first four explain what 2BSIQ is and how it is
done. The next two explain the origins of 2BSIQ and the road CT1BOH took
into it. The last three sections provide valuable insights about this
contesting mode compared to others and the key factor to obtain super high
rate QSOs (6,7,8,9,10 QSOs per minute).

4 - “Secrets” of 2BSIQ

10 "secret" points to keep in mind

5 - Origins of 2BSIQ

SO2R, Inband, TO7A Interleave

Why isn't TO7A making more QSOs


6 - CT1BOH road to 2BSIQ

Alternating RUN from KH7R in 2000
Dual CQ with advanced SO2R
Understanding Multi-Single Inband operation
Inband technique
Increasing QSO total with Inband
CR3A, P33W, 4O3A teams
TO7A/UT5UGR interleave QSO mode
TO7A/UT5UGR YouTube videos
357.8 QSO/hour rate is not good enough?!
TO7A 20% QSO increase far from 40%
TO7A graphical waterfall reveals the problem
Perfect interleave synchronization graphic waterfall
2BSIQ concept is born
Training 2BSIQ with CW simulator for CQWW CW 2015

7 - Is 2BSIQ better than SO2R?

2BSIQ increases QSOs but...

Is that enough to overcome the decrease of multipliers?

Comparing S&P, RUN, SO2R, 2BSIQ from a baseline score
Adding 20% more QSOs makes 2BSIQ equal to SO2R
Comparing CR3E (SO2R) with CR3OO (2BSIQ)

8 - Can the SOAB world record be broken with 2BSIQ?

Targetting EA8BH record

2BSIQ opens a new possibility

CR3OO, TI5W and ZF2MJ operations

Is the record still possible this cycle?

9 - Is zone 33 still the best QTH for record breaking

Super High QSOs rates with 2BSIQ

TI5W and ZF2MJ minutes with 10 QSOs

% of USA in normal and super rate minutes

Impact of high % of USA, simultaneously on the two radios

QSOs per hour according to % of USA for CR3OO, TI5W and ZF2MJ

The importance of having many hours with USA

Why hours with higher % of USA are better for 2BSIQ

Time to fly to zone 9 or 10
