is there some support for request for "AUTO CW ON/OFF" firmware
function as some rigs are having (FT-897)?
It means SSB mode choosed, RX in SSB mode normally but when Key is
activated (touched for CW sending) there is automatic shift of carrier
and CW is transmitted (as in standard CW mode, SEMI or FULL-BK etc.)
then going back to SSB mode for RX. Hope you understand :-)
This is very useful during UHF/SHF contests (with transverters) when
calling CW CQ but takers are calling in SSB (mostly or very often). No
need for switching mode (you have SSB all the time) and to touch dial
knob to reply etc. Very comfortable and (I hope) not so serious for
firmware.
I know this is very special and on HF bands there is probably no reason
for such function, my experience is based on serious contesting on
higher bands (1296 and up).
This facility is essential on all VHF/UHF bands - and that categorically
includes 50MHz.
VHF/UHF DXers switch freely between SSB and CW to deal with weak and
fading signals. If someone calls CQ on SSB, but cannot copy your SSB
reply, what you need is the ability to switch to CW and have your signal
come up where the other station can hear it.
Yaesu rigs automatically shift frequency to do this, so what the other
operator hears is your CW signal at the normal pitch that you have
selected. Obviously the reverse applies too - when you switch back to
SSB, the signal is very nearly tuned in.
Until recently, Icom rigs did not have this option - when you switch to
CW, you'll be calling at zero-beat, fiddling with the XIT (which way???)
and cursing Icom's name!
As Lexa says, this isn't difficult to provide as a firmware option, so
please let's have it.
