new K3S (10195) and audio level drop when KPA500 in Oper mode
 
|
Good morning,
I have a new K3S, serial # 10195. All was going well until I hooked up my KPA500 to the K3S using the Elecraft supplied aux cable (E850463). In standby mode (on the KPA500) the audio level on the K3S is nice and loud, BUT when I press the OPER button on the KPA500 the audio level on the K3S all but disappears! If I then press STBY on the KPA500, the audio level on the K3S returns to loud. Only the E850463 cable connects between the two Elecraft components. The KPA500 is about 1 year old and has performed flawlessly to date. Do I have a Firmware issue with the "older" KPA500 and the brand new K3S? Thank you for any suggestion on how to resolve this issue.

Perhaps your KPA500 key line is being pulled low? Might be a cable issue.
I think there's an asterisk on the left side of the KPA500 LCD that shows when the PA KEY line is being pulled down. 73 de Dick, K6KR -----Original Message----- From: Elecraft [mailto:[hidden email]] On Behalf Of jim rogers Sent: Saturday, August 29, 2015 9:07 AM To: [hidden email] Subject: [Elecraft] new K3S (10195) and audio level drop when KPA500 in Oper mode Good morning, I have a new K3S, serial # 10195.

Jim,
Did you check what the K3S power level displays when the KPA500 is in Operate mode? It could be set for very low drive. I have mine set up to lower the drive from 100w to 30w when the KPA500 goes from standby to operate. If you have the setting for per band mode enabled, you will need to check it on each band.

Warren,
His problem was in receive, not transmit. So I don't understand how the drive level setting could have anything to do with it. 73, Don W3FPR On 8/29/2015 3:52 PM, Warren Merkel wrote: > Jim, > > Did you check what the K3S power level displays when the KPA500 is in > Operate mode?

Have the units been moved? Updated? Disconnected/reconnected since working?
If so: Please power off the amp and rig. Pull the cable and check for pushed/bent pins. Just a shot in the dark.

Don,
Of course it wouldn't in RX. Excuse me. I was under the impression that the OP was referring to TX and the TX "audio", so I'll stand on my comment. Just trying to help sort it out. The OP didn't specifically state RX or TX so how do you *really* know? Warren On 8/29/2015 4:35 PM, Don Wilhelm wrote: > Warren, > > His problem was in receive, not transmit.

Jim;
Dick’s advice is sound. When in OPER mode, the KPA will display an asterisk on the left side of the display when PTT is applied. If you are seeing that indicator, check the PTT connections to see if there is a short to ground. When using the KPA with your K3S, you should only use the AUX I/O cable, nothing should be plugged into the PTT jack on the KPA500. If this is the case, then check the AUX I/O cable to make sure that no pins are bent. If you see one bent over, try to straighten it without breaking it (might be difficult) and try the cable again. There were no firmware changes for the KPA500 for the K3S. The interface and use is identical to that with the K3. The latest shipping firmware is V1.38, which is what you should be using in your KPA. - Jack, W6FB Elecraft Engineering > On Aug 29, 2015, at 9:06 AM, jim rogers <[hidden email]> wrote: > > Good morning, > > I have a new K3S, serial # 10195.
