In case of problems:
LED switches from GREEN to RED when operating software to TX.
Some radios may go into TX but send no DATA.
Some radios will not go into TX.
[a]
Some radios such as Icom 706 require baud rate to be set at 1200.
This selects the appropriate pin on the 6 pin DATA socket for PTT (1200 rather than 9600).
This does not in any way affect the speed of any DATA transmission it simply selects the pin used for PTT.
[b]
Some radios FT857 etc require radio to be in “DIG mode” which you should define as “USER-U”.
LED does NOT switch GREEN to RED when operating software to TX.
[a]
The soundcard is NOT SELECTED for both INPUT and for OUTPUT.
[b]
The drive level from the PC is too low to activate the interfaces PTT line – increase drive level.
Use the Windows “balance” control if you wish to reduce DATA drive while maintaining a high PTT drive.
One audio channel is used for DATA, the other channel being used for PTT.
[c]
The soundcard is “muted”.
It is not always easy to see if Windows has muted the audio.
The easy way to “un-mute” the soundcard is to view the driver in device manager, right click and remove
the driver.
Switch the interface off then back on and Windows will re-install the driver “UN- muted”.
LED rapidly switches between GREEN and RED when operating software to TX.
[a]
The drive level from the PC is too low to activate the interfaces PTT line – increase drive level.
Use the Windows “balance” control if you wish to reduce DATA drive while maintaining a high PTT drive.
One audio channel is used for DATA, the other channel being used for PTT.
NOTE:
When using the YL02A DATA lead your radio will need to be in the correct mode;-
FT-920
FT-990
FT-1000MP
FT-1000MKV
FT-2000
FT-5000
FT-9000
