It's all about the Software

Sorry to ask. First time user. Googled multiple time and cannot find it. May be i searched wrong place? Where is the SDRC specific help and manual?

Which menu and sub menu to get to rit and xit?

How is the maths? Say display freq is 10 ghz, rit xit both plus 1khz, actual tx rx at 10g + 1k or 10g - 1k? Assume tcxo zero error. Many thanks

Hi Simon

No written manual as such but much information about the program is found at Simon's website, by carefully exploring all the drop-down menus at the top of the page:

https://www.sdr-radio.com/

XIT/RIT is achieved (as far as best of my knowledge anyway) by split operation using the settings in the TX DSP panel to turn off "Sync RX" and adjust TX frequency independently, plus buttons to sync RX frequency to TX or vice versa:
No offset is displayed as such, just the actual RX and TX frequencies in their respective places.
