16711RE: [perseus_SDR] Re: CW and CW-R
- Nov 3, 2011Hi Lasse,
No you are not a Simpleton and thanks for the help! Just checked the tones
and they seemed to be matched up. So I will forget the bar over the CW and
RTTY modes. For some reason I thought the tones were reversed, that what
you get with no sleep. I assumed wrongly that if you are on CW-R it was
reverse from the Icom. What was messing me up in the beginning was BobCAT
after the modes where added so I was really chasing my tail. I had a lot of
things going on and to sort out.
So if this is like Harry's I am good to go.
Thanks Lasse for hanging in there with me!

I may be a Simpleton...
I still do not get what's wrong with your set up!
Icom CW and Perseus CW-R are technically the same! Just different names due
to the fact CW never have had a standard. So when a designer decides that CW
for his (or her) radio will use one of two sidebands the opposite sideband
will be reversed.
IF they instead had name it CW-LSB and CW-USB, noone would be confused :)
When Commander sends its CW command (CI-V sub-command $03) it will set both
your Icom and your Perseus to the same CW-LSB setting Nevermind that Perseus
shows CW with a bar over it....
Do you get the demodulated tones to go higher in one RX and opposite in the
other.. then you do have a mismatch.
If so, let us know!
