The NRD-525 can do it with a little trick. I bet the 535 and perhaps
others can do it too.
This RX has a BFO to tune the listening tone of a CW-signal only. This
is set to 800Hz in top position but you can vary it to at least
pus/minus 1.5 khz. So setting it to zero beat on the carrier frequency
is not a big deal.
Ok, I'm a little confused here. I thought the carrier frequency of a CW
transmission was where the was *no* tone. Otherwise, how would you know if
they were transmitting on 6999.2 or 7000.8 KHz (assuming zero beat at 7000
KHZ)? Either freq would give you an 800 Hz tone.
My NRD-525 did it, though there may have been an offset that could be
changed. I've since sold it so can't verify. I suspect the NRD-535 does
also. My Drake R8B also zero-beats in all modes by default. The Icom R-75
does NOT do this in CW mode, you can only adjust the offset between 300 and
900 Hz.
There is another thread relating to this a bit further down called "What GC
SW radio would you buy for about $1500".
