Re: [Elecraft] K3--CAT IS command will shift IF while in TX
I had noted the same problem with HRD but attributed it to HRD. I had not been playing with the IF shift, but did have some RF feedback problems that came from an USB dongle soundcard I was experimenting with. It also messed up some of my other settings, so I just reloaded a previous configuration I had saved with the utility. That took care of the problem and I didn't think about it again until I saw this post. Jim - W0EB I was asked by John, K0VET, to verify a behavior he observed last night on his K3. He was playing with HRD and found that by changing the IF Shift while transmitting that it took him off frequency. He demonstrated it for me and sure enough, his radio went off frequency (1.947 LSB). I fired up the K3 utility and issuing the following commands, IS 0500; and IS 1800; I was able to replicate the behavior on my K3. As soon as I stopped transmitting and transmitted again I was back on frequency even though the shift was still in effect on RX. So, what I surmise is that the IF shift is not locked out on the CAT port while transmitting. Both John and I have the latest 4.22 firmware loaded. The front panel Shift control does not exhibit this behavior. 73, de Nate N0NB __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
