CW transmitting - any clicks?
Locked
 
|
This may be a stupid question, but does the KX3 click at all transmitting CW? For example - when I stick my headphones on with my FT-857D it still clicks between RX and TX. It makes it impossible to have quiet, non-bothersome QSO's in camp when everyone else is trying to bed down for the night. I can throw some clothes around the rig but that doesn't solve the problem, just dampens it.

Steve,
Except for the noise my straight key makes, I've never noticed any noise from the KX3...

Steve,
The K2, K1, KX1 and K3 all have electronic Transmit/Receive switching, and I would expect the KX3 will as well, so there will be no relay clicking noise. 73, Don W3FPR On 12/1/2011 7:06 AM, Steve KC8QVO wrote: > This may be a stupid question, but does the KX3 click at all transmitting CW? > For example - when I stick my headphones on with my FT-857D it still clicks > between RX and TX.

It is only the very faint quantum clicking of PIN diodes... but you
need really good ears to hear it :) 73, Drew AF2Z On Thu, 01 Dec 2011 04:06:49 -0800 (PST), you wrote: >This may be a stupid question, but does the KX3 click at all transmitting CW? >For example - when I stick my headphones on with my FT-857D it still clicks >between RX and TX.

My K2 emits a very faint "tick" sound at the end of each dot and dash - I
can hear it if I put my ear near the back of the K3. This happens using the internal keyer and a straight key, although it's extremely hard to hear using a straight key as the mechanical sound from the key itself masks it even when releasing it very gently. It's not coming from the speaker. Have other people noticed this? I wonder what is causing it? It does this even with the power level set to zero and I have VOX+QSK set. 73 de Graham G3ZOD FISTS #8385 http://www.fists.co.uk -----Original Message----- Steve, The K2, K1, KX1 and K3 all have electronic Transmit/Receive switching, and I would expect the KX3 will as well, so there will be no relay clicking noise. 73, Don W3FPR ______________________________________________________________ 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 |

The last time this came up, Wayne theorized that it might be the sound of slight mechanical adjustments in the relays as power is redistributed. They aren't being switched, but the coil voltages may be changing slightly, inducing an audible modulation in the electrically shiftable parts. Hunting it down was on his rainy day list :).

I am sure Wayne has a lot on his "rainy day" list.
And as the old song goes, "It never rains in California... but man it pours." 8-) 73, Bruce, N1RX > The last time this came up, Wayne theorized that it might be the > sound of slight mechanical adjustments in the relays as power is > redistributed.

Like the K3, the Ameritron QSK-5 uses PIN diodes to perform the T/R
function. I hear the same "tick" from the QSK-5, only louder. Because there's a relay inside the QSK-5, some ops have come to the conclusion that the relay is generating the tick. It's not. The relay is used only for bypass purposes. To prove this, I removed the relay from the unit and the tick remained. As best I can tell, the tick noise is made as the diodes are biased. Now, why that would happen needs to by explained by a semiconductor subject matter expert. Some of the noise may be amplified by the manner in which the diodes are mounted -- much like the transfer of sound from a string bridge to the top plate of a violin.

Due to the superposition of click and not click, the answer is both until
someone listens, then it is either click or not click. Due to the same principle, my answer is both right and wrong until someone reads this reply. ;-) George, AB4FH |
