Re: [Elecraft] Sherwood receiver test on KX3

It appears that the kx3 does not have dynamic image rejection, rather a one time calibration for image rejection. Has there been any talk of the KX3 implementing dynamic image rejection? Perhaps a future SW revision where the image rejection goes to 90 dB. The Flex products implemented dynamic

[Elecraft] Sherwood receiver test on KX3

The Sherwood test of the KX3 says this in the notes for the superscript V At 1 kHz performance is opposite sideband rejection limited. On CW consider switching to 8-kHz IF. Note: Roofing filter disabled in this mode. I do not see anything in the manual about the 8 Khz IF mode. It is my

Re: [Elecraft] Sherwood receiver test on KX3

So if you are running an panadapter and turn on RX shift then what happens to the panadapter display? Are the frequencies shifted on the display by 8 KHz? The Sherwood data would indicate to me that using the 8 KHz shift is a good thing to do all the time if you do not have the roofing filter and

[Elecraft] general coverage receive on X3

wiil the KX3 receive at ~8.5 MHz or ~12 MHz without diminished sensitivity? If the sensitivity is diminished, by how much? tks Dennis -- View this message in context: http://elecraft.365791.n2.nabble.com/general-coverage-receive-on-X3-tp7559086.html Sent from the Elecraft mailing list

Re: [Elecraft] general coverage receive on KX3

I am not talking about the need to desense because of an IF frequency but that the front end ham band filters may still be active when doing SWL. It is my understanding that the K2 can receive SWL but its front end filters are ham band only so if you are between any ham bands the sensitivity

Re: [Elecraft] general coverage receive on KX3

the kx3 manual describes these front end filters as follows The relay-switched low pass filters are used during both transmit and receive. A few of the filters are dedicated to one band but most cover two bands. The signal on the antenna side of the filters pass through a forward/reflected power
