[TenTec] cw creation

Re: Name one for instance so we can check it out.

Yea, really! I know a lot of rigs unbalance the balanced modulator with 
a DC input to generate CW. And I read in this thread that an old Collins 
used the audio tone input to the balanced modulator. What other rig 
generates an audio tone on CW and uses it for anything other than the 
sidetone? I'm sure there must be one, can you name one?
...

In any case the best way to get a clean CW signal out of most rigs is to 
use CW mode and a key input, NOT SSB and a keyed audio tone input.

That is what this thread was about! The method a SSB rig uses to create CW.

Yes, and someone asked about using a sound card for CW generation. This 
may have the same result, but is not the same as the transceiver 
producing CW, when it is in CW mode, by generating an audio tone within 
the transceiver and sending it into the balanced modulator. I still 
maintain that using the rig in CW mode and keying it with a contact 
closure at the rig's key input (or using a builtin keyer) is in most 
cases going to produce a cleaner CW signal than running a sound card 
into it in SSB mode. There may be exceptions with certain rigs that 
produce bad CW. Yaeclix 1000s maybe.

...

A great many rigs use a single sinusoid audio tone to create a psuedo CW 
signal.

I await your list of rigs that do this.
