SO2R/Advanced SO2R

Using 'advanced SO2R' mode and setting up scenarios

Advanced SO2R is a mode that frees the operator from the SO2R control equipment and controls the audio and transmitting of radio1 and radio2 automatically according to pre-defined scenarios and the moment of the QSO.

Using 'advanced SO2R' mode

Required Hardware

Advanced SO2R mode and setting up scenarios requires external SO2R control equipment of the last generation, communicating with Win-Test via a USB port . So far only EZMaster from HamRadioSolutions and MK2R from microHAM have this possibility

Understanding basic concepts

There are three dimensions that need to be understood:

• Transmission into radio1 or radio2

• Reception of radio1 only, radio2 only or radio1 in left ear and radio2 in right ear at the same time

• Different and automatic transmission and reception control of radio1 and radio2 according to the moment of the QSO.

The last dimension is the reason for calling advanced SO2R mode.

Moments of a QSO

A QSO can be divided into four moments: (1) CQ’s and end of QSO’s, (2) listening to the pile up, (3) sending call and report to station heard in pile up, (4) getting report from station.

Imagine the following contest CQ between CT3NT and ZD8Z.

• Moment1: TEST CT3NT

• Moment2: zd8z

• Moment3: ZD8Z 59933

• Moment4: tu 59936

• Moment1: TU CT3NT

What are the actions of the operator at CT3NT using Win-Test?

• Moment1 (CQ’s) starts when the operator at CT3NT push the F1 key in Win-Test.

• Moment2 starts when Win-Test finishes sending F1

• Moment3 (sending call and report) starts when the operator at CT3NT push Insert key in Win-Test.

• Moment4 starts when Win-Test finishes sending F1

• Moment1 (end of QSO) starts when the operator at CT3NT push the + key log the QSO with ZD8Z.

Setting up scenarios

A standard F1 message contains only the content of what is sent, i.e. F1=TEST CT3NT. When using Advanced SO2R mode the F1 message will have the content plus the scenario to control audio and transmitting. Imagine the following scenario:

F1= $R2R2 $F1 $R1R2

This simple scenario will do the following. When the operator push the F1 key, Win-Test will switch the headphones to radio2 only ($R2R2), transmit $F1 (the content of standard F1 message (TEST CT3NT) and when that is over will switch the headphones to left ear in radio1 and right ear into radio2 ($R1R2).

$R2R2 $F1 set up the audio headphone settings and transmission in moment 1 of the QSO

$R1R2 sets the audio headphone settings for moment 2 of the QSO

Now imagine a more complex scenario

F2= $R1R1 $F2 $R2R2 $TR2 $MSG1 $R1R2

When the operator pushes the F2 key, Win-Test will switch the headphone to radio1 only, transmit the content of standard F2 message (59933), when that is over switch the headphone to radio2 only, transmit the content of additional message#1 into secondary radio and when that is over switch headphones to left ear in radio1 and right ear in radio2. The above scenario is used when sending a report to a multiplier in the second radio and a quick call in run radio to keep frequency busy.

The user can configure the scenarios in the menu Operating | Modify the scenarios. There is a wizard with five pre-defined scenarios, but the user can change them and use his scenarios according to his skill and his SO2R expertise.
