Hello all,

I programmed my GT-5R with CHIRP-Next and all was fine, except when I tried to program a simplex channel in my radio to access my SHARI AllstarLink node.

In the memory tab, I set "Duplex" to "off", as the logical choice among "+", "-", "split", and "off". But when I tried to transmit after loading that channel into my radio, it would not transmit (no RF, display color didn't change).

It is working as expected. Duplex: 'off' is TX disabled (not simplex, not +, not -, not split)

Duplex: '(none)' or '{blank}' is TX freq = RX freq (aka simplex) # CHIRP-legacy or CHIRP-next respectively

So I went in, looked hard at the settings, and discovered there was another option lurking in plain sight - " " (blank).

When I selected (blank) and loaded the radio with the modified channel, it worked fine (TX as expected, in simplex).

If I look at the (actually pretty good) GT-5R manual that shipped with the radio, it says I have three choices for that field, menu item 25, SFT-D:

"OFF [0]" TX = RX (simplex) "+ [1]" TX higher than RX freq "- [2]" TX lower than RX freq

There's no mention of "split" or "off".

This is menu 25 (SFT-D) in the radio. It is only applicable when the radio is in VFO mode and has no direct correlation to the Duplex setting in CHIRP

In short, the only valid options appear to be "-", "+", and "off", which I guess could be set to " " (blanks).

Again, this setting has nothing to do with channels in MR mode and no direct relationship to the Duplex setting in CHIRP.

I just thought I'd share this here, I'll open an issue on the chirp-next website to get this fixed.

Don't open and issue. Nothing is broken so there is nothing to fix.
