[TenTec] Omni VII with digital mode, VA2AM, Rejean

[Réjean Léveillé]

Seen that I am new with Ten-Tec radio I will split my questions.
I got going Omni VII for RTTY with FSK in transmit without any problem. My concern is on the receiving side, I already have a Rigblaster plus for the digital mode and to run RTTY or PSK31, the signal out from the accessory-1 seems to loud. I must keep my sound card line-in all the way down to almost zero otherwise I get flagged overflow (WinPSKse232) and MTTY high noise floor. I use to connect my sound card with other rig with 600 mv output and the line-in setting was almost half scale.
Is there an adjustment I could do or TT output is settled at 1 volt from the factory?
Thank you, 73 Rejean
