The normal/reverse is confusing.  What is called  normal and what is reverse depends on the service.

All you have to remember when using a ssb transceiver and feeding audio into it is if one way does not work you can either switch sidebands or use the normal/reverse switch on the demodulator.  Either one will work but do not switch both at the same time or you will be back to where you started.

Subject: [GreenKeys] Normal and Reverse

This issue that Mark K1HF had, really brings to light this issue of normal and reverse is a curious one. The MD-522 used with the GRC-106 (iirc) the term “normal” means mark low space high. And given this is a USB only radio then the space tone would in fact be a higher frequency carrier signal than the mark.

However, curiously, in order for my CV-2460 to interoperate with the Saturday rats nest, I need to set it to R/R (reverse transmit/reverse receive). So the CV-2460 is either expecting a different “normal” or expecting to be used in an LSB environment. Given it is navy equipment, I suspect it was not expected to be used in LSB (nick?). Therefore, it might appear that the navy had a different opinion of “normal” than the army.

No idea about any of this, I’m just happy I can get it to work!
