Re: [Amateur-repairs] Creating a LSB and USB Test Signal!!

I'd just inject a 1KHz tone into the mic jack or aux audio input and crank the RF output of transmitter to minimum.  No fancy test gear is needed.  Transmit on USB or LSB,or AM.  Use the MOX function for transmit control.

Subject: [Amateur-repairs] Creating a LSB and USB Test Signal!!

 

I have been working on a receiver that has a USB and LSB problem. I am using my Icom IC-705 radio as a test source. I want to replace this with something that will generate a USB or LSB Test Signal continuously so I can inject it into the receiver and then check stages of the radio etc. etc.
I have most test equipment available but was wondering if anyone has done this and what type of test equipment setup they have used.. 
Thanks in advance for your help...
