Re: [Elecraft] K3 RX does not always work at power up
Does your K3 have gold pins on the front panel connector? The old tinned pins were apt to cause a lot of weird/intermittent problems. Glad you were able to fix the D25 issue.

George, something like that happened to me a while ago. Reloading the firmware fixed it. 73, Dave K1ZZ Sent from my iPhone > On Nov 2, 2022, at 12:56 PM, George Fremin III wrote: > > > > The K3 that went deaf and I replaced D25 in - has had another issue > that I have not understood - and it is only annoying when it happens. > > Sometimes I will turn it on and it all seems fine but it hears zero > signals - it is not that it is deaf it is more like it is not > working.

[Elecraft] K3 RX does not always work at power up
The K3 that went deaf and I replaced D25 in - has had another issue that I have not understood - and it is only annoying when it happens. Sometimes I will turn it on and it all seems fine but it hears zero signals - it is not that it is deaf it is more like it is not working. It does have receiver hiss that makes you think it is fine and it seems to transmit (although I have not tried to listen to it to confirm) but it just does not work at a receiver. I should try the TX next time. Power cycling the radio once or twice usually makes it work right away and it is fine. It does not fail like this at every power on. This radio is being used as a remote radio - and I leave it on almost all the time - that is one reason this is not been more of an issue and often I forget it does this - until I power it on. Like last night after replacing D25 - and the radio seemed deaf - but even more deaf than before as it coudl not even fainly here the signal generator. Then I remembered the power on issue and I turned it off and back on and it came to life. It is an older K3 that has been mostly upgraded to a K3S. Single receiver. 2m module. Newer pre amp.
