Neil,
You need to jump in the way back machine and go back a few years. The
TW-1 was a talking SWR/power meter made by LDG that went out of
production several years ago. It covered HF and 6 meters. The TW-2
was for 144 - 440 mhz and is also no longer made.
They may turn up for sale from time to time, but most blind ops who have
one aren't letting go until something better comes along.
There has been recent discussion here about the powermaster/hampod
combo, or the Wavenode WN-2, and the desire for something a bit more
affordable for a lot of hams.
