Perhaps the RxAnt is selected? Easy to do, easy to miss. Done it more times than I care to remember. 73! Jack, W6FB > On Jul 26, 2019, at 7:42 PM, Mpridesti via Elecraft > wrote: > > Sorry- did not fully see the problem > > The receiver is not working on any band not just 40. Sounds like b

Re: [Elecraft] Sudden K3 failure

Sorry- did not fully see the problem The receiver is not working on any band not just 40. Sounds like band noise on all bands (sounds the same on every band). Did a comparison with a second K3 to confirm the no receiver problem on all bands. Previously found by rotating some of the tmp conne

Re: [Elecraft] Sudden K3 failure

Confirmed that at an early stage of the trouble shooting. No difference with either antenna selected (only one port has an antenna). Regards, Mark, K1RX > On Jul 26, 2019, at 7:28 PM, Dennis Moore wrote: > > Any chance you accidentally switched antennas on 40m? > > Dennis NJ6G > >> On 7/

Re: [Elecraft] Sudden K3 failure

Any chance you accidentally switched antennas on 40m? Dennis NJ6G On 7/26/2019 13:21, Mpridesti via Elecraft wrote: Although I was able get the TX running again by merely doing a small twist to all the TMP connectors that were reachable with top cover removed and behind the front panel, unabl

Re: [Elecraft] Sudden K3 failure

Although I was able get the TX running again by merely doing a small twist to all the TMP connectors that were reachable with top cover removed and behind the front panel, unable to bring back the receiver front end on 40 m. I hear noise and very weak signals but nothing like the normal band noi

Re: [Elecraft] Sudden K3 failure

I would get some Deoxit and remove the KPA3 from the main board. Apply minimal amount of Deixit to the connector pins and insert/remove the Amp about 10 or 15 times. Wipe pins with lint free tissue and re-apply Deoxit (use toothpick) and insert the amp firmly and reassembled the radio. Let u

Re: [Elecraft] Sudden K3 failure

Mark, While you may be correct about the TMP connectors, open the K3 and rotate the TMP connectors a bit to wipe away any oxidation. If it continues to fail after that, email supp...@elecraft.com for further ideas on how to proceed. Tell them what you have attempted so far. 73, Don W3FPR

Re: [Elecraft] Sudden K3 failure

Interesting Powered up radio again and worked fine again. Within minutes failed again so I am suspecting the tmp connectors as suggested by K1XX (and others) and the SYM area. Regards, Mark, K1RX > On Jul 25, 2019, at 9:40 AM, Mpridesti via Elecraft > wrote: > > Appreciate all the sugg

Re: [Elecraft] Sudden K3 failure

Always try reloading your backup configuration.  Usually works for me. George, W3HBM On 7/25/2019 8:24 AM, Mpridesti via Elecraft wrote: > [This message came from an external source. If suspicious, report to > ab...@ilstu.edu] > > Yesterday while just listening to a SSB

[Elecraft] Sudden K3 failure

Yesterday while just listening to a SSB QSO, the receiver just went quiet and when I tried to transmit, got nothing. Power setting was at 75 watts and varied properly but meter and external output monitor was showing nothing. Thought the filters stopped passing RF. Rechecked the filter sett
