Weird AGC Behavior
Locked
 
|
Has anyone experienced anything like this?
I am using a K3 (FW version 4.39; DSP version 2.73) with a KPA500 amp connected to the K3 with the Elecraft AUX cable. I normally have the AGC set for AGC-S when operating SSB or digital modes. If the K3 is in receive mode for several minutes, the AGC turns itself off without warning (accompanied by a hugh volume increase from the speaker). While this doesn't happen every time, it has happened several times. It seems to be most likely to happen if the Noise Blanker is turned on and the KPA500 amp is on and ready for operation (as opposed to being in standby mode). When I installed my KPA500, I upgraded the K3's firmware to the above versions. I have no idea what is causing the AGC to turn itself off, or if it has anything to do with the firmware upgrade, the amp, or both, or neither. I would appreciate any help that exorcises this demon. 73 de K6SBA David in Santa Barbara CA ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

David,
Are you running Ham Radio Deluxe? If so, that is what is turning the AGC off. My understanding is that this is a problem with the fast polling rate used by HRD. Last I heard (more than a month ago), Simon was looking at some sort of fix, but I have heard no further information. 73, Don W3FPR On 9/19/2011 12:22 PM, David Inger wrote: > Has anyone experienced anything like this? > > I am using a K3 (FW version 4.39; DSP version 2.73) with a KPA500 amp > connected to the K3 with the Elecraft AUX cable. > > I normally have the AGC set for AGC-S when operating SSB or digital modes. > If the K3 is in receive mode for several minutes, the AGC turns itself off > without warning (accompanied by a hugh volume increase from the speaker). > While this doesn't happen every time, it has happened several times.

Are you using Ham Radio Deluxe? That's a known bug of HRD. 73, ...

Simon has sold HRD so I would not hold your breath for a fix.
