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
Kenwood Radio
– NO DATA OUT.
No TX audio but led switches to RED (TX).
Do NOT configure your software to activate PTT via the CAT system.
Operating PTT via the CAT system on a Kenwood radio will open the microphone for input and mute the DATA input.
