Next to be programmed is the Input/Output values which are shown below.
Don’t be tempted to use ‘Valid Signal’ instead of ‘Carrier Detect’ as this means the data, which
doesn’t have a CTCSS tone attached, won’t enter the rebroadcast unit so only the voice signal is
sent.
Likewise ‘PTT Ext Data’ must be used rather than ‘PTT Ext’.
A ‘Data Volume’ of 15 as recommended earlier results in good but not ‘punchy’ audio. If you are
using the programming software set at Level 3 then you will also have access to the audio level
controls. None of these other than the ‘Compression Gain’ need to be changed but bringing this
up from 0 to 6 or even 12 will increase the level of transmitted audio without risk of distortion to
the GPS data.
