Feidaxin 450A - Settings for duplex use

I don't plan on using duplex on any channels other than 1-8 (leaving 5 for emergencies of course) - in fact I really only plan in using channel 4 - our local repeater - but will set up all 1-8 for mobile use. Tim.

Thanks Steve.

Thanks Mike. I think I understand.

I now have Channel 31 set to 477.175MHz, the repeater offset at 0.75MHz and the repeater shift at - (Thanks to Steve). I assume this means when on Ch 31 I transmit at 477.175MHz and receive on 477.175MHz - 0.75MHz = 476.425MHz (The channel 1 repeater output freq). If I turn on Reverse mode, I transmit and receive on 477.175MHz - just like if the repeater shift was set at 'same', or the offset value set at 0MHz.

What I'm now unclear on is how the radio knows which channels to apply the offset value to. Is it a 'global' setting for all channels? It appears reverse mode cannot be saved (ie. it turns off when you change channels), and the repeater shift is a global setting.

When on Channel 31 you should be transmitting and receiving on the same channel.When you are on Channel 1 duplex you should be transmitting on + 0.75 Mhz.- Steve

To operate on Repeater 1 you should have recv on 476.425 and transmit on 477.175.

Can't you just program separate transmit and receive frequencies into a memory for the 8 Repeater channels ?

If you want to operate Simplex on Chan 1, just program another Memory for recv and transmit on 476.425.

The offset value and or shift doesn't appear to be channel specific on these radios. Only the reverse mode is channel specific, but this is not a 'saveable' setting.

You are better off NOT using Offset and Shift.
