Hi Dick, I would be interested in participating. Using a Flex 6700 via the KXUSB cable from amp direct to USB port on radio. Set up to track the TX slice on radio. Been working fine. Flex has a setting to auto poll. I also have written a flow for Node Red to monitor and control the amp via a web browser.

Re: [Elecraft] Elecraft K3 problem
Hi Per-Tore, I don't know if there's an easy way to check the PIN diodes in the T/R switch, especially since the SMD components of the switch are mostly on the underside of the RF board. Here's where I would start: 1) Find spots on the RF board (top side) where you can measure the control voltages 7R and 7T. Verify that these change in opposition to each other, i.e. if 7R is high, 7T should be low and vice-versa, when changing from RX mode to TX mode and back. 2) Presuming that both voltages 7R and 7T behave properly in switching from RX to TX mode and back, I would measure the voltage on the drain of Q7, the MOSFET switch, when 7R is high. Assertion of 7R should pull the Q7 drain voltage low, which causes sufficient current to pass through both PIN diodes D26 and D27 to enable the RX signal to pass through, presuming there is not a problem with PIN diode D25. 3) It is possible that the Q7 drain voltage could be pulled low if only one of PIN diodes D26 or D27 functions properly and the other has failed open, so test (2) is not conclusive. 4) If you have a scope with a 10X probe, I would check for presence of RF on the anode of PIN diode D43 when in TX mode - any frequency on the VFO within the scope bandwidth should suffice. D43 must be forward-biased by the 7T voltage in order for RF drive to be coupled to the low power (10 Watt) PA assembly (Z2 on the block diagram). The fact that you have not been able to detect any transmitted power in TX mode whether the 100 watt PA is bypassed or not may indicate that the low power PA is not receiving drive from the mixer. The 7T voltage is supplied to the anode of D43 via the low power PA input connector, but it's unlikely that the simple path internal to the low power PA board is at fault, i.e. 7T is not reaching D43. I haven't had my K3 opened up for many years, nor have I experienced the problem you described, so I can't easily point out where to access the circuit points mentioned above. There is another set of PIN diode switches around the mixer, but I would start with those closest to the low power PA before going further back up the signal processing chain. 73, Mike, K8CN -- Sent from: http://elecraft.365791.n2.nabble.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] Elecraft K3 problem
Would not that make the rx dead? I can hear strong signals. But the tx is giving no output. - 73, Per-Tore / LA7NO -- Sent from: http://elecraft.365791.n2.nabble.com/ __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Did you check the antenna selection? -- 73, -John NI0K https://www.qrz.com/db/NI0K LA7NO wrote on 7/27/2020 7:50 AM: Hello, The K3 suddenly stopped working. One day all OK, the next day serious problems. Serial no.: 07818. It has ATU and 100 W PA installed, and also a P3 connected. Both K3 and P3 were earlier well calibrated. Supply: 14,5 VDC. Symptoms: - Rx seriously reduced sensitivity, only strong signals to be heard. - No Tx output. Tuning not successful, no SWR indicated (only the 3 hyphens). - Same on all bands. - All displays, controls and menus apparently working normal. - Mic-gain & ALC normal indication on SSB. All menu settings seem to be OK. Connected an XG3 and injected a -73 dBm signal. It showed up on all bands with signal level about -100 dBm, so around 30 dB attenuation. Connected a LP-100A and a 50 ohm dummy load. Whatever we tried, the LP-100A indicated zero power out on all bands. Same on both Ant1 and Ant2. Bypassed the ATU: no change. Set power to < 10 W, effectively bypassing the PA: no change. It is clearly something that is common for both Rx and Tx. It is independent of the selected band. Apparently not related to ATU or PA. So, it could be some relay problem, or related to the SWR bridge or LP-filters. Hope you can give some helpful ideas on how to proceed.

Re: [Elecraft] Elecraft K3 problem
May be a LO problem. Check all of the TMP cables. Wes N7WS On 7/27/2020 5:50 AM, LA7NO wrote: Hello, The K3 suddenly stopped working. One day all OK, the next day serious problems. Serial no.: 07818.

[Elecraft] Audio output routing confusion
After 6 months off the air, I find myself confused by the K3's audio output choices. While I'm able to hear the Main A VFO and Sub RX VFO through my one speaker, I can't figure out how to (or if) hear both the Main RX A and B VFOs through that speaker. Is there a way to configure this, or do I need a second speaker or must I use headphones?
