Today I discovered a strong microphonic birdie at 21.273MHz in main and subreceiver. I'm sure it wasn't there prior the KRX3 installation So I tried the hints posted here at the list, rerouting of the TMP-Cables and refastening of all the screws. After a couple of hours try, a screwed up TMP-Cable (thank God there was a spare cable with the KRX3), two extra ground connections from TMP-Cable plugs to the shielding, I succeeded to reduce the birdie to almost inaudibe. But when I installed the top cover again, the birdie in the main receiver got stronger. With removed top cover the birdie is barely audible, but as soon as I get close with the cover it reaches S4. I tried to position the TMP-Cabels again, but no success. Every time I put on the top cover, it came back to S4. Finally i gave up after another 2 hours try. A quick check of the other bands showed also a S4 birdie in the main receiver at 50.047.8MHz.
Does anyone know about this and maybe got a solution to this? 73 de Roland, DC1RS -- View this message in context: http://n2.nabble.com/Birdie-after-KRX3-installation-tp2165027p2165027.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
