Hello everybody!!!! I think I made a mistake! Testing the T-4XB I had connected my 2-C to the RX connector of the T-4XB. A dummy load was connected to the antenna connector and a mute was connected betenn the 2-C and the T-4XB. The 2-C function was on EXT mute, but one time I set it on "ON" so the mute was excluded. That was by mistake and I tuned up the TX to the dummy load. I heard a strange strong buzzing sound from the receiver and the S-meter all the way up. Actually that happened even twice, also speaking at full modulation. Now I see at least 40db less in the second IF stage at 455Khz. At that moment I didn't really got the problem as I was all focused on the T-4XB. I also hoped that the relay was enough to save the RX and I thought that all the power would have been dissipated into the dummy load.
Where should I check first? Tubes, or could also coils and preselector be damaged? 73, Frank IZ2OOS _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
