[Elecraft] Fixed: K1 AF sidetone loudness proble
Hello, i got it fixed. The fix was described earlier in this thread - replacement of Q10 (2N7000 Mosfet) and Q11 (J309 JFET) on the RF Board did it for me. By the way: The J309 seems to be discontinued..

Re: [Elecraft] K1 AF sidetone loudness problem ?
Hi Don, thanks for Your reply - midwhile i found an other suggestion too in the mailing-list. Q10 and Q11 j309 and 2n7000 where changed and the click went away. .so i have a lot of possibilitys to work on hi. I will keep you informest. The k1 4 band is a vy nice radio - i wish the kx3 has ist form factor (but i know it is only possible by shrinking our fingertips.

Roland, Your suspicion about the T/R switch *may* be correct, but before you make any changes, check the menu for the T-R setting. The default is 50 ms. If you are using a small value, the receiver may be unmuting quickly enough that you actually hear a bit of the residual RF. I was not able to view your video - OneDrive just keeps 'spinning its wheels' as if it is loading, but I waited for over 5 minutes (two times) and it still did not load. 73, Don W3FPR On 1/11/2015 12:11 PM, Roland_DF1OE wrote: Hi Don, finally i did the reset of the radio and all the alignment procedures again.

Re: [Elecraft] K1 AF sidetone loudness problem ?
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!856authkey=!AJAxQrX x4ZPblzAithint=video%2cMOV authkey=!AJAxQrXx4ZPblzAithint=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.

Re: [Elecraft] K1 AF sidetone loudness problem ?
Hi Don, i did all the steps Mike suggested to me - some more e.g. resoldering some suspicious pads. The K1 is still in the workbench. I will start building the internal atu, but will first fix this issue. Before resetting the radio i will put a small audio/video file on the internet, and give you both a note for examining it. 72, 73 Roland, DF1OE -- View this message in context: http://elecraft.365791.n2.nabble.com/K1-AF-sidetone-loudness-problem-tp7596933p7596960.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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 Message delivered to arch...@mail-archive.com
