Hi Don, finally i did the reset of the radio and all the alignment procedures again. I managed to get the loudness of the sidetone ok (but i am still thinking one oft he T/ R diodes openes slowly ), but as a result now i have a strong "burst" at every tone (only if hf is on). Even if the sidetone is off and hf is produced the burst is heard - it grows loude with the af gain, so it is produced before the AF amplifier - hope so.
You can see/hear it in this little video: https://onedrive.live.com/redir?resid=FBF8BAC7649FCD9B!856 <https://onedrive.live.com/redir?resid=FBF8BAC7649FCD9B!856&authkey=!AJAxQrX x4ZPblzA&ithint=video%2cMOV> &authkey=!AJAxQrXx4ZPblzA&ithint=video%2cMOV The burst is vy loud and a pain even in the headphones - so i keep on searching. and will look on the frontpanel U2 and so on.

You may want to try resetting the K1 to factory defaults (which wipes out your menu settings and replaces them with the stock factory defaults). Before you do that reset, record all your menu settings so you can restore them - but some such as the CAL OPF values will have to be done from scratch. Do know that the sidetone level on the K1 does vary with the setting of the AF Gain control, so if you are change the AF Gain during transmission, the sidetone level may increase/decrease with the AF gain. Still, a loud sidetone with SL L set to 1 should be very quiet. If the reset does not correct it, I would first replace Front Panel U2, next FP U1, and last FP U3. 73, Don W3FPR On 1/9/2015 9:57 AM, Roland_DF1OE wrote: > Last Year i built my k1 #3310 - i got one of the last 4-Band filter boards. > With the k1 i had some fun as TF/DF1OE/p last year in iceland...
