View Full Version : What's this?
A real beginner's question?
What's this (http://www.drmrx.org/forum/attachment.php?attachmentid=35893&stc=1&d=1194017960)? I always get this on 1611 kHz and 729 kHz.
It's probably the carrier of a co-channel AM station.
I don't think that you have a co-channel carrier on 1611 khz. I think that this are interferences from the DWT itself or the PC. The DWT has a lot os these interferences an you can see themin weak signals.
I remember listening to 729 without any problems. I can listen to OldieStar 1575 with out these interference.
Thanks for your detailled answer ;)
...Well, image frequencies or mixer byproducts...
....Something like the one in the attached png. The pike is not an AM TX interference, its a RX's faulty mixer byproduct !
I just found out that the "birdie" on 729 and 1611 is actually QRM of my notebook's touchpad... :rolleyes:
Have you taken care of it and how ?
well I think the only way to avoid this QRM is using a usual PC mouse in future. :rolleyes:
