Hi again fellows! Last mail I said my K2/100 want regulate down power on lsb ,but usb sounds fine. After some investigations I found this not to be true. Here is what actually happens. And Eric or Wayne! I would like your thoughts on this also.
First ! My setup is : K2/100 #3829 Butternut HF9V Groundmounted with radials in ground. Alinco power 80cm below K2 at 14,1V. All bands 10-20meters ssb and 10-160cw is working as it should. No hum or ripple at all. Audio OK. Not hifi , but no one report bad so for me all except bad is OK. (I just one of the guys that want to get understood!) (Married??? YES!) 40/80meter ssb? Well! Audio partly OK. 40meter audio OK. 80meter audio on antenna OK ,with dummyload it is broken up. If I set 50 watts on 80 meter and switch to 40 the rig put out 100watts anyway. If I then wistle high pitch loud in mic. power goes to 170-180 watts. It wan't regulate down power. If I set power to max and wistle low tone and pitch and the regulate down the rig will respond and regulate power. It will then remember powersetting until bandchange again , and if I switch to 80 that memory is lost and an setting of 50watts is not remembered. It wan't regulate down until I wislte low tone/pitch while I regulate from max and down again. I tried to split the K2 and KPA100 and the result was the same. I don't think the KPA100 is straying over to the K2. For me it seems like the KPA100 is strying to it's microcontroller. Why? Because when I whistle , sometimes the fan tries to turn during whistling. When I stop whistling , the fan stop. I had done the refastening of hardware on the KPA100. It had get loose after 10 hours of fun. Did not get things better. Is this a grounding problem or something else. If I was advised to check that and this I would do it and report back. Also the KSB to carrier balance is rechecked and adjusted. It is no difference on usb/lsb other than usb puts out a litle lower gain than lsb , but problem is the same. I can live with this now ,but not if I was to run a 1KW PA with the K2 witch is my intensions for later. HELP!!!! Have a nice weekend all!
