I seem to be missing the point of this PTT CW keying thing... Is it for
transverter/linear/mast head pre-amp use on VHF/UHF?
A useful feature that was mentioned a long time ago (and put on the back
burner I think), was adding a programmable transmit feature to one the
"PF" buttons to give a carrier for linear/ATU tuning. I have this
feature on my Kenwood TS-480 and find it invaluable. Pressing thw 480's
PF button toggles a carrier on and off (regardless of mode), the carrier
level can be adjusted while it's transmitting via the normal power
setting route and can be set anywhere from 5 to 100 Watts in one Watt
steps (the power setting limits of the 480). The power level is stored
and occurs regardless of the main power level setting, so for example if
I'm set for 5 Watts of QRP CW, pressing the button gives me 10 Watts for
the external MFJ auto ATU. If I'm using my valve linear and have the 480
set at 25 Watts on SSB, pressing the PF button gives me 10 Watts to tune
the linear with. This is similar, if not the same functionality, as
those external 3rd party button boxes do for the Yaesu FT817/857/897 rigs
Has this use of one of the three PF buttons been included yet?
