Re: [Elecraft] [K3] Noise on wsjt-x waterfall

Jim, K9YC suggested some places to look that I hadn't thought of. When I turned off the "Flatten" option in the waterfall window, the noise bands went away. What I think is happening is that the algorithm in wsjt-x that flattens the response for the window sees the total lack of energy outside

Re: [Elecraft] Experience with KX2 indoors

As I mentioned previously on this list, I operated WPX CW from northeastern France in 2004 with my 10 watt K2 (running 5  watts) and a W6MMA MP-1 mini-screwdriver antenna plus counterpoise from a 6th floor hotel room.  The antenna was sitting on a table near the window and I worked quite a bit

A similar change was released in KX3 firmware 2.38 on 1/3/2015. Max power was increased from 12 W to 15 W. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Nov 30, 2017, at 2:44 PM, Larry Reynolds lreyn...@verizon.net [KX3] >

[Elecraft] [K3] Noise on wsjt-x waterfall

I have a K3 which has been upgraded to have the Elecraft internal USB sound card. I tried adjusting the DSP bandwidth when running FT8 to eliminate a strong signal above the FT8 subband and noticed that there was a strong noise bar on the water fall for about 400 Hz below the high cutoff.

Re: [Elecraft] CW Contest and Elecraft K3s decoder

Yes, I find this to be true as well.   I also suggest one tweak the TEXT DEC value to something other than AUTO.  In my experience a value of 3 or 4 works well. 73 Bob, K4TAX On 11/30/2017 3:45 PM, Bill Frantz wrote: I get "reasonable" results. What I find is that the faster the sender,

Re: [Elecraft] CW Contest and Elecraft K3s decoder

I get "reasonable" results. What I find is that the faster the sender, the better the decode. The ways I have found to improve decode are: Use CWT to exactly tune the signal. Use narrow bandwidth -- 250 Hz or less on the DSP filter Adjust the RF gain to minimize noise while still having

Re: [Elecraft] Experience with KX2 indoors

I often use the KX2 indoors with one of two temporary antennas: 1) A 3.9, 7.2, and 14.3_MHz 76' trapped and coil-shortened center-fed inverted-V (dipole) with a SOTAbeams 1:1/15W balun, pitched on a 10m MFJ "fishing pole", and terminated on some 6' wooden fence posts. This connects to my shack

[Elecraft] Experience with KX2 indoors

I have a W4OP 40-10 meter end-fed mounted in the peak of the attic of my single story home. I managed to work VP6DX (Elecraft sponsored) a few years back with a 10W K3 on 40M SSB (two times, early mornings local) as no one else seemed awake to call. Also into Europe since on 40, 20 and 17.

[Elecraft] USB Charger from KX3 Battery

I'm planning to take the KX2 on a long trip, and it occurred to me that it might be useful to be able to charge my phone from its battery.  I just took apart a cheap automobile charger and wired a socket to its input.  It works down to about 8 V.  You could build your own, but at $3 it's hard

Re: [Elecraft] Experience with KX2 indoors

Paulette, As with any antenna, if you can get it outdoors and in the clear, your noise pickup will be drastically reduced compared to using it indoors. Although when mounted outdoors, the manual tuning may make it difficult to tune from the KX2 location - so put on a short length of coax,

[Elecraft] Experience with KX2 indoors

What is the experience of operators with the KX2 indoors.  I am going to start using a KX2 with a W4OP antenna and I am concerned about getting out a signal. Paulette WB9VHFMadison WI USA __ Elecraft mailing list Home:

[Elecraft] KX2 max output now 12 watts (experimental)

The latest KX2 field-test firmware allows power output to be set as high as 12 watts on 80 through 20 meters. (Max out is still 10 watts on 17-10 meters.) Supply voltage must be 12.8 V or higher on key-down. ~14 V supply recommended. Yes, this is only about 1 dB, but it did help me snag XF1IM

[Elecraft] K3 PRE function question

This is a pretty simple question regarding the K3 PREamp (not PR6). If I do not have the PR6 does the PRE on the front panel help with RX on 6m/2m (int module) or does it merely increase noise? Thanks -- Randy Lake N1KWF 73 Gunn Rd. Keene,NH
