[OZAPRS] TT3 works on HF but not on VHF

[Russell]

Hi David,

Just checking ,  The TT3 is set basically for hand held operation when first
constructed. (microphone input grounded)

If you use the TT3 for mobile use it is advisable to remove R8 a 2K resistor
from the board (just cut it, or switch it)

Regards

I got my replacement TT3 which now shows a valid GPS light, and I
tested it on 40m and it worked fine. I then reconfigured it for VHF
and tested it on my mobile antenna but no success. It transmits fine
and I receive it on my base.
Thinking my mobile which is very immobile at present (repairs) had a
dicky antenna or was located in a bad spot, I then set up the same
radio and TT# on my 2 meter J beam which I normally use to access the
repeater- still no luck.
 
The TT3 is configured.

The TT3 is connected to GPS and show valid GPS and transmits-
confirmed receive signal on my Kenwood 2m rig.
My radio is an Icom706MkIIG
The TT3 triggers transmit via the mic socket
The rig dial is set to 145.175 MHz
 
Why is my signal not decoded and not appear on the internet?
