Re: [Elecraft] KPA500 No Output on 6m
Hi Dave, More information would be helpful. Are you seeing your radio's output thru the KPA500 (and on the meters) with the amp in bypass mode? Is the radio's PTT properly keying the amp? Etc.

Re: [Elecraft] KPA500 Issue
In my case, it was not the PIN diodes themselves, but failure of R9. I'm away from my shack right now, so may not have the resistor ID correct. It is a 48 Ohm resistor. I fixed the problem by parallel connecting a pair of 1/4 W, 100 Ohm resistors across the open one. Problem solved. Been fine since. There is documentation of this problem. A German ham wrote to me with a link to the solution. If no one steps forward before tomorrow, I'll try to post the info in the morning. 73, Jim - WS6X On Thu, Mar 31, 2022, 6:40 PM Andy Durbin wrote: > "However, what I’m seeing is that when the amp is in OPER mode, my receive > signal strength drops way, way off to the point I have to go full AF volume > to hear signals.

Re: [Elecraft] KPA500 TR switch mod kit
You might be referring to this from an Elecraft repair invoice: "Replaced Q5, D7, R3, R9 and R24 for Transmit/Receive MOD (Improves robustness in Transmit/Receive circuitry)." My KPA500 was back to the factory in March and had this mod installed. That didn't help much in the "robust" department, because my amp went south almost immediately after its return. Apparently the PIN diodes D8, D9 and/or R7 have failed. I received many replies to my question on this forum from others who had the exact same issue. The symptom is recieve signal is attenuated about 20 dB when Operate is engaged; normal in Standby.

Re: [Elecraft] Digest questions / new K4 list or group
The digest is a real pain for the very reason you mentioned... many subscribers, for whatever reason, don't remove all the non-pertinent stuff. I have seen one post that was 3 digests deep! To avoid that, you have 2 choices. Either change your delivery to individual emails, or unsubscribe and go to the site at your leisure. Jim - WS6X On Tue, Sep 8, 2020, 7:55 AM Steven G.
