Relay noises??
Locked
 
|
Gday everyone,
Iv noticed over the last few days when the K3 is just turned on (from cold for the first 30sec. or so) turning the tuning dial causes relay chatter type noises in the transceiver!! Has anyone had any experiences with this? The radio is only a couple of months old. Ive also seen flashes in one of the gaseous arrestors on TX soon after installing the atu board (it seemed the k3 was in a confussed fault condition (swr was ok)) cheers, Graham VK3XDK |

Hi,
I think there might be a minor bug in the K3 firmware when switching antennas in Diversity mode. Context: Have 2 antennas, connected to Main and Aux, that even on the same frequency give you signals which are different enough that you can tell the difference. In normal (non-diversity mode) make sure you have both receiver and sub-receiver antennas set to Main. Switch to diversity mode. Click B-Select Set sub-receiver antenna to Aux. Click B-Select ..so far so good, we are in diversity mode, subreceiver set to go with Aux antenna. Now, suppose I want to change the NR settings on Subreceiver. Click B-Select ooops, I can't hear what I used to hear through the Aux antenna, for some reason the sub-receiver is now connected to the Main antenna (the non-diversity setting for the antenna). Click B-Select the Sub is again on Aux antenna, and everything is normal Click B-Select the sub is again on Main antenna This behavior will not happen if the Sub was set to Aux antenna BEFORE going into Diversity mode. So is this normal ? Or it is a bug that was not spotted before because usually the signals between the two antennas do not vary strongly enough to be noticed, and/or people set their Sub antenna before going into diversity mode. I think intuitive operation mode would be to either have just one antenna setting for subreceiver regardless of being in diversity mode, or, have the different settings, but then when in diversity mode, make sure the sub stays connected to the Diversity setting. Thank you, Adi 2E0TTX ______________________________________________________________ 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 |

Adi I'm away from my shack to check your question but here's a little tip for you. It's not necessary to go into BSET to change the Sub RX antenna. If you HOLD RX ANT, it will toggle the Sub RX antenna between Main and Aux...just like TAPping RX ANT will toggle the Main antenna between ANT1 and RX ANT. I seldom use BSET and look forward to the dawn of the K4 when it should not be necessary at all! (i.e. all Sub RX settings will be visible on a large display at all times). :-) I don't know if you've discovered a bug but may check later when I'm at the rig. 73, Bill |

When you are in diversity, you are using many of the settings from RX
A in RX B. When you hit B set, you will also find that RX B uses the VFO B frequency, which will cause you to not hear the RX A frequency when for example fiddling with the NR or NB to see if they help reception. You need to remember to do It is clear that going to BSET drops out of diversity until you are finished with it. I'm not sure I would call that a bug, as once you know about it, you do the workaround easily enough, but it would be nice if it didn't do that. You have to drop the BSET to return to diversity phase lock. Dropping the frequency if you've been tuning around, particularly if all you want to do BSET is look at the B S-meter, is a pain in the patooey. None of the cheep fixes work (like move A->B as part of BSET) because VFO B contents may be intentional. If that was done as a quick way to drop out and listen elsewhere in diversity, I'm annoyed, and would want that behavior as an option that I could turn off. 73, Guy.

It is normal for the synthesizer relays to switch periodically as you tune the VFO dial. It is switching between different VCO frequency ranges.

I would expect the relays to switch occasionally but they actually chatter! (only when the rig is cold it seems)
Thanks for the replies. |

I subscribe to this too.
