[GreenKeys] Normal and Reverse

[Ralph Mowery]

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.

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!
