K2 Sidetone Problem
Locked
 
|
I have upgraded my firmware to the latest revision. (and replaced the I/O controller). The sidetone is gone. There is no option to change the source, it stays on U8-4 when I tap the display button.
When I put the old IC back, the sidetone returns. My K2 is an older (1644) rig and I don't have the 100 watt option or the the KIO2 option installed. Does anyone have any ideas?

I'd like to suggest that the two non-numeral keys on the keypad (i.e..
SPOT and AFX) be used for access to general-purpose memory with M->V and V->M. I guess these keys would then refer to memory locations 10 and 11, joining 0 through 9 of the other keys. I don't really pay attention to the numerical key labels for memory access, just the key positions on the keypad. So the two extra memory buttons would be quite useful even without numerical labels. Why not put them to use for memory access. 73, Drew AF2Z _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Hey guys,
I just went ahead and did the U8-4 mod and of course the sidetone was there. Maybe the firmware was changed so you didn't have a choice. Everything else seems to work OK. Thanks and 73, Larry, NU4B

Larry,
Version 2.04p firmware does have the sidetone source toggle, so it should work. Are you really tapping the DISPLAY button or are you really pressing it (a HOLD operation). If all else fails, go to the KIO2 or KPA100 manual (download them from the Electrtft website), and make the Control Board wiring change - it consists of one cut and two added wires (plus a .001 uF capacitor) - not really a lot ot it. The U8-4 sidetone source is more reliable than the U6-25 and several of us who deal with K2 support and repair situations have been lobbying Wayne to eliminate the selection and glue it to the U8-4 source, which would require that owners of K2s below SN 3000 would have to make the wiring change if new firmware is installed. 73, Don W3FPR gearjam wrote: > I have upgraded my firmware to the latest revision.

Folks,
OK, I looked at the firmware chip that I received just today, and it is level 2.04R instead of 2.04P. I do not have confirmation, but from Larry's report, it may be that the sidetone source is now fixed at U8-4. If so, it will solve a lot of problems that users have, even though it may prove to be a minor inconvenience for those who still have older K2s without the sidetone source change. I am going out on a limb here without confirming information, so be gentle if I am later proven incorrect. 73, Don W3FPR gearjam wrote: > Hey guys, > I just went ahead and did the U8-4 mod and of course the sidetone was > there.

That is exactly the difference, and the only difference, between 2.04P and 2.04R. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Lyle,
Thank you (and Gary, Scott and others thank you and Wayne for that change). Now the documentation for the firmware needs to catch up - it is not mentioned in the sheet that is shipped with the firmware. I am copying Ron on this so he has a 'heads up'. 73, Don W3FPR Lyle Johnson wrote: >> OK, I looked at the firmware chip that I received just today, and it >> is level 2.04R instead of 2.04P. >> I do not have confirmation, but from Larry's report, it may be that >> the sidetone source is now fixed at U8-4... > > That is exactly the difference, and the only difference, between 2.04P > and 2.04R. > > 73, > > Lyle KK7P > ------------------------------------------------------------------------ > > > No virus found in this incoming message. > Checked by AVG - http://www.avg.com > Version: 8.0.169 / Virus Database: 270.6.21/1669 - Release Date: 9/12/2008 2:18 PM > > Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I just received the firmware today (Sat) and I checked and it was 2.04R. And your right the documentation was not up to date yet. At some point I would have had to do the mod anyway. (My first thought was something was wrong. Panic first, ask questions later. Hi) Thanks again for all the info.
- Larry, NU4B

Hi Larry, I had the same problem and it was because of a not working I/O controller.Elecraft sent me a new one and the problem was gone. 73, Chris-OE5CSP |
