[TenTec] 2.8khz and Carrier Balance???

[Steve N4LQ]

Would someone please explain to me what changing the filter from 2.4khz to 
2.8khz has to do with carrier balance.
I see no relation. The carrier is nulled by balancing the dc voltage on U4 
of the TX Audio board. No filter is anywhere near there. U4 feeds DSB into 
the 9mhz filter but the carrier must be nulled before it gets there so whats 
going on with all this carrier balance talk I keep reading about?????

Subject: [TenTec] Adding 2.8 filters in Omni VI opt 3


I have had the Inrad 2.8 filters in my Omni VI for several years, both IF's. 
I think they're great. Plus the audio mod.

I just got my Omni VI back from S-ville having the TCXO unit installed and a 
realignment done. During that work I recieved an e-mail from Don at TT 
saying
they could not properly adjust the "carrier null" with the 2.8 filter in 
place, (9Mhz IF I believe), that I would have to have a 2.4 filter 
installed. Since I also have the Inrad 2.4 filters in both 2nd filter 
positions. Don just interchaged them and finished the job.

Just a comment, for what it's worth.
