Re: [Elecraft] KX2 ... Any KX2 users on this list?
Hello Gordon, this is another KX2 user ;-) I bought mine last year and did not really use it regularly so far, just a bit listening on the bands, but that should change very soon. Today a fellow OM (also owner of a KX2) helped me to configure WSJT-X and I had my first FT8 QSO with my KX2. But my main use will be SSB... until I manage to be good enough in CW to be on air. 73 DH4FT, Thorsten Am 30.01.20 um 04:05 schrieb Charles G.

Re: [Elecraft] KX2 ... Any KX2 users on this list?
I can confirm the good reports on the KX2. I've been using mine for a couple years for portable operations, without a hitch. The receiver sounds almost as good as my K3. The battery is good for 5 or 6 hours of CW contest operation at 10 W. If you really want to keep the weight down, the KX2 battery can charge a phone. A modified USB car charger plugs into the battery connector. That battery could charge a phone several times. One very slight annoyance is that Elecraft never fixed the filter software: It only works at bandwidths of odd multiples of 50 Hz: 250, 350, etc. I happen to like mine at 400. 73, Scott K9MA On 1/30/2020 22:20, Joseph Shuman via Elecraft wrote: I have been using a KX2 with the ATU a little over a year, my first and only radio.

Re: [Elecraft] SWR Calculation
Not directly that I'm aware. Personally, I have a Bird 43P on the output of the amp. That way I can read the forward power and then reflected power with a reasonable amount of accuracy. Then using the Bird VSWR Nomograph I can accurately determine VSWR. With 500 watts output then if the reflected value is: 0.6 watts = VSWR 1.07 1.1 watts = VSWR 1.1 2.5 watts = VSWR 1.15 5.0 watts = VSWR 1.22 8.5 watts = VSWR 1.3 15 watts = VSWR 1.4 28 watts = VSWR 1.6 55 watts = VSWR 2.0 If you have more than that, you need to do some antenna work. 73 Bob, K4TAX On 1/30/2020 12:58 PM, Richard wrote: Is there any way to make the KPA500 display rateflected power?

Re: [Elecraft] Diversity Comments
Hi Dennis, I don't intend to discourage experimentation, but its useful to be aware of the underlying science before investing time, money and effort with low probability of a successful outcome. The type of diversity we employ -- two receivers feeding two human ears -- isn't likely to improve SNR for signals buried in noise. Its greatest benefit is in combating fading. Some independence in fading characteristics can be obtained either with: - two antennas of the same polarization separated by about one wavelength or ideally more, or - two antennas of opposite polarization. Antennas very close to the ground -- for example, Beverages and BOGs -- are always vertically polarized, NEVER horizontal. Why? The electric field of the horizontally polarized radiation broadside to a wire close to the ground -- or laying on the ground -- is effectively "shorted out" by its proximity to conductive soil. But a horizontal wire has vertical polarization off the end of the wire. The electric field off the end of the wire is perpendicular to the ground and is not "shorted out" but its still lossy when the antenna is very close or especially when laying directly on conductive ground. A BOG performs best when its not laid directly on soil, it should be kept at least supported a few inches above the soil by vegetation or other means. The only exception is if the BOG is laid on sand having little to no moisture or organic content. 73 Frank W3LPL - Original Message - From: "Dennis W0JX" To: donov...@starpower.net Sent: Thursday, January 30, 2020 2:00:39 PM Subject: Diversity Comments Good Morning Frank, Thank you for your complete and useful comments regarding diversity reception. I have been operating my K3 in diversity since I purchased it in 2009 without understanding the technical requirements for useful diversity receive. There is no way that I can achieve a wavelength or even half wavelength separation between my receive antennas! I use a Hi-Z 4 square RX antenna system which I always have connected to the K3 sub RX. That system, of course, is vertically polarized. I initially began using 450 foot beverages into the Main RX and that seemed to provide some diversity RX benefits. These were separated from the HiZ system by about 100 feet. However, due to growing noise sources surrounding me, I had to abandon these antennas. Then in 2012, I began to experiment with flag loops connected similar to DHDL's. These have proven to be much lower noise antennas and have been my favorite receiving antennas for some time. Because these are vertically polarized, I assume that diversity reception does not occur because the HiZ system is also vertically polarized. My main question to you is this: For diversity to work, is it necessary for BOTH antennas to actually hear the DX signal? This seems logical to me but so often on 160 or 80, one antenna system hears the DX station and the other does not depending on angle of arrival of the DX signal. Perhaps diversity receive is not as useful as it appears to be if your conditions cannot be met. On the other hand, isn't there some added benefit from the combining of signals? BTW, I am installing two 300 foot phased BOGS aimed north. It will be interesting to see how they will perform in diversity mode since they are horizontally polarized. 161 and hope to work you in the Marathon this weekend.

Re: [Elecraft] K2 On The Air!
Mark, big congrats! I am really happy that you successfully finished your K2 and it is working as it should. You made a great job! I have my own K2 #4800 still in the setup and I will never sell it as I like it too much :) I am sure you will make a lot of nice QSOs and you will enjoy it. See you on the air soon. - 73 - Petr, OK1RP "Apple & Elecraft freak" B:http://ok1rp.blogspot.com MeWe: https://bit.ly/2HGPoDx MeWe: https://bit.ly/2FmwvDt -- Sent from: http://elecraft.365791.n2.nabble.com/ __ 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

Re: [Elecraft] KX2 ... Any KX2 users on this list?
Yup, I’ve got one here - it keeps my K3-Line company. Use it for QRP operating, usually in the back yard when weather permits. Nice little rig. Jim / W6JHB > On Jan 29, 2020, at 7:05 PM, Charles G.

Re: [Elecraft] K3S, VOX and WSJT-X?
The major issue I've found in using VOX for data modes lies in the fact
that any noise {hum, buzz, clicks, broadband noise, Windows sounds,
RFI, etc.} coming out of the computer can and will trigger the VOX.
This is specially true if the VOX gain is too high. Also, the VOX delay
does affect turn-a-round time and must be set to minimum. That in
itself then requires the operator to change VOX gain and Delay when
reverting to SSB. Of course if one doesn't use VOX for SSB it is a non
issue. And if in digital modes the VOX Gain is high and such that the
system is driven into distortion, VOX audio chain, that will affect the
delay time.
I agree with Don in that I find CAT is the better and most assured mode
for transitioning between RX and TX. As to CW using VOX with the K3S,
that is totally internal to the radio. A very different condition than
one running an external application.
At the same time, I am not exactly clear on using multiple decoders. I
presume from what I've read, then each decoder has the option to
transmit. Thus the issue of conflicts with port assignments will likely
arise. Me, I prefer to keep life simple and use one mode at at time,
running the application from the base application and not from within
other applications. I find life to be simpler and much less stressful
but more reliable, thus not having to frequently determining what
changed and why it doesn't work today.
This is totally independent on running one application and one decoder
or multiple applications and decoders. It is not a race, it is a
hobby. Thus coming in first has little merit.
Just remember, we are all going to get to the same place at sometime in
the future. The mortuary cooling slab could likely be one place.

zero volume and full volume, and it will work well for keying the

Re: [Elecraft] KX2 ... Any KX2 users on this list?
I have used a KX2 for several years. Very pleased with it overall. I use it portable at home to make operating outdoors easy but I also enjoy SOTA and POTA operations when time and location permit. For a time I used it as my only rig coupled with a KXPA-100 amplifier. It has a very nice, well thought out, feature set. Tim N9PUZ On Wed, Jan 29, 2020 at 9:07 PM Charles G.
