Excuse me, but what is this LDG TW2 being spoken of here? Also, does
anyone know where I can get accessories for the Wouxun HT's? The dealer
I was using no longer works with the Wouxun company.
thanks.

Tom,
You need to set to the proper band on the TW-2. Your choices are: 50,
144, 220, and 440.
To hear the currently selected band spoken do a quick press and release
of the FWD and SWR
buttons at the same time. To change band do a longer press of these
buttons and you will hear a tone followed by the newly selected band.
Repeat as needed to get to the band you want.
The manual says being on the wrong band will give you a reading, but
not
accurate.
