Hi Paul, yes of course.
1. Remove all cables and use some ESD protection (at least discharge themself to grounding point) 2. Unscrew four main thumb screw and open the KX3 carefully 3. In the middle you will find flat (like PC) flex cable (we say ribbon cable) conecting both sides together 4. Even although it seems that on both sides the flex cable is seating well in > remove it carefully on both sides. You will have two parts of KX3 > still connected together with battery cable (if installed as shown on Page 41, Fig. 62 of manual) + the flex cables on the table. If the battery opt. is not installed then you will have two separated KX3 parts + ribbon cable on the table. See the page 40, 41 of the manual here: https://ftp.elecraft.com/KX3/Manuals%20Downloads/E740164%20KX3%20Kit%20Assembly%20Manual.pdf 5. Clean the pins in PCB with isopropylalcohol and blow out dust residues in connectors on the flex cable 6. Re-seat/instal the flex cable back to KX3 carefully. Be sure that the ribbon cable is oriented with the long tab toward the speaker and all pins are engaged when you will put it back to your radio. See Fig.61 on Page 41 of the manual here: https://ftp.elecraft.com/KX3/Manuals%20Downloads/E740164%20KX3%20Kit%20Assembly%20Manual.pdf 7. Check again that flex cable seats well fully engaged and there is nothing forgoten inside of KX3. 8. Close the top and bottom covers of your KX3 carefully and secure them with thumb screws. CAUTION: As you close the covers ensure that the flex cable folds into the space next to the CP board connector as shown. Do not allow it to fold toward the battery holders. If the flex cable resists pushing into the space next to the CP board connector, use your finger to gently crease it along the edge of the connector as shown in Figure 61 of the manual. 9. Turn on KX3 and enjoy with all buttons functioning again... :) Hope it helps. 73 - Petr, OK1RP On Wed, May 22, 2019, at 6:50 PM, Paul Gacek wrote: > Petr > > I took a tumble coming off a SOTA peak this weekend doing a rather > precarious summersault via my pack which had my KX3 in it. > > It now has failed in exactly the same way you described. > > Can you possibly re-share the fix as I’ll try it before sending the KX3 > (which has seen so many peaks and foreign countries) back to Elecraft. > > Paul > M0SNA/W6PNG > www.nomadic.blog > > > On May 22, 2019, at 10:02 AM, Petr, OK1RP/M0SIS <indi...@xsmail.com> wrote: > > > > Hi all, > > > > some time ago also I reported that the MSG, PRE and ATTN buttons on my KX3 > > stopped working.
