I don't think it will, or does. To get, say a 800 hz tone, one must off

I
know, vs. the R5000 which did read the carrier frequency in CW and RTTY as

I
recall.

However, if you can discover something in the manual, I'd be interested in
reading it.


That's what I meant. If a station is transmitting in CW mode on 7000.00 KHZ
and the radio is tuned to 7.000 KHZ you will not hear a tone, only the
"swish-swish" as the carrier is zero beat.


Yes, but one can't copy CW that way. Now, with the R5000, as I recall, the
offset was already built in at 800 or 1000 Hz... and if you tuned to the carrier
frequency, voila, you were copying code. That is what I meant! The R8x series
does not have that, so one must off tune from the carrier frequency.

Many publications always list the carrier frequency of a station, so unless the
offset is built in, one must always off tune from that listed frequency.

The same with USB/LSB/RTTY modes
on my rig. Naturally, this assumes a perfectly aligned radio that doesn't
read off by 20Hz like so many do. My unit uses Rev. 12 firmware (press and
hold the down arrow key while powering on to read your firmware revision) so
maybe others are different.

I was thinking there was a programmable offset but the manual doesn't give
any; I may have been thinking of the NRD-525.

The Icom R-75 on the other hand has a programmable offset but only between
300 and 900 Hz. You cannot zero beat that radio in CW mode unfortunately.
