[Elecraft] K3 RX Problem
I just purchased a new to me K3-10 S/N 501. I have discovered it has a RX sensitivity problem. After some troubleshooting, I have discovered that the RX is not low on sensitivity (about .25 uV) but has a high noise level when receiving thru the ANT 1 or 2 ports. The background noise with no antenna connected is 10 dB higher on the TX/RX ports than when it is receiving thru the RX only ports. Possibly this is related to the PIN diode antenna switch? Has anyone on the list experienced this? Thanks!

Re: [Elecraft] K3 - RX Problem after latest firmware update
OK Stewart. I did not think that would really be the problem but I wanted to rule it out anyway. I'm passing this on to Wayne as he is going to have to find what in the firmware that may be causing this to happen. I tried last night and could not reproduct it, but I have seen very few reports of similar situations. Tnx for your patience while this is sorted out. - 73, Greg - AB7R Whidbey Island WA NA-065 K3#0009 and 0319 On Tue Mar 11 9:12 , Stewart Baker sent: >No TCX0-3 fitted.

Re: [Elecraft] K3 - RX Problem after latest firmware update
This was true with some early optional TCXO-3 units that had exposed SMDs on the bottom of the can. There was a capacitor that could potential short to the metal socket where the missing pin would have been. Hence the addition of the insulation. This is not a problem with the standard reference oscillator as there are no exposed parts on the bottom. Stewart, Do you have the optional TCXO-3 and what is the radio's serial number? - 73, Greg - AB7R Whidbey Island WA NA-065 K3#0009 and 0319 On Mon Mar 10 13:16 , "Bruce Bowman" sent: >Hi Stewart- > >Like you, I had a problem with my K3 going dead.

Re: [Elecraft] K3 - RX Problem after latest firmware update
Hi Stewart- Like you, I had a problem with my K3 going dead. Unlike you, I bought a factory-built unit. I did that because I wanted to know it was working properly from the start. That turned out to be one of those things that sounds like a good idea but doesn't withstand close scrutiny. What I saw initially was an occasional error message (ERR PL1) when switching to another band, then the audio would decay to nothing over a 2 second period. Sometimes I could get it to recover by chnaging bands, sometimes not. Since it was factory built, they had me return my K3. They found the TCXO3-1 oscillator was grounding occasionally. The oscillator would continue to operate, but grounding it (the case? some component? dunno) caused the frequency to be pulled about 20 KHz and the receiver would die. They replaced the oscillator (probably unnecessary), added an insulator and re-ran VCO calibration. It's been rock-solid ever since.

[Elecraft] K3 - RX Problem after latest firmware update
I am not sure if there is an obscure problem after the latest MCU and DSP update. Maybe others could check and see if it happens to them ? Any band on SSB if I have the DSP set to ALT1 with the Low Cut set at 0.15 Hz , then after going onto transmit the receiver appears to be dead. If I set the DSP to NORM by pressing the knob the receiver suddenly bursts into life... This happens whether there is any transmit audio or RF out. 73 Stewart G3RXQ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
