Re: [Elecraft] CW issue
Turn on the 15 db attenuator in the receiver or put a 20 dB attenuator in the line from your antenna to receiver. If the key clicks continue, it is a good bet they are being transmitted. If they go away, it is front end or mixer overload. On 1/29/2016 8:21 AM, Gmail wrote: I have a 6 meter beacon, 50.63 MHz, about three miles from my house.

Thanks Don, Using yours and others suggestions I determined it was the transmitter.

Re: [Elecraft] CW issue
Ray, It could be that the beacon is actually generating those keyclicks. Try turning off the preamp in the K3S and or turn your beam so the side is toward the beacon. Are the keyclicks eliminated? If so, it may be too strong a signal into the K3S, but if they continue, they are likely being generated by the beacon. Remember that the K3S has input protection. In the form of a Carrier Operated Relay and has a mechanism to turn off the preamp if the signal is too strong. If you tune to the beacon frequency, turn on the preamp and point your beam at the beacon do you hear the COR relay clicking in the K3S or is the preamp turned off automatically? If so, that is too much signal into the K3S. 73, Don W3FPR On 1/29/2016 9:21 AM, Gmail wrote: I have a 6 meter beacon, 50.63 MHz, about three miles from my house.

Re: [Elecraft] CW issue
Probably an Icom, they are bad for key clicks. Check his website or QRZ page and see if it says what he is using for the beacon.

Very unlikely. Is your Noise Blanker turned on? That can cause clicks. Otherwise, I'd say the beacon has REALLY bad clicks. Clicks should not be audible farther than 2 kHz from a signal, and even that would be considered dirty. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
