[Elecraft] [PX3] Reduction of radiated noise at VHF - a solution

Since I purchased my PX3 I have suffered from radiated noise at 144 MHz. It takes the form of various buzzy spurs evenly spaced across the band and quite easily seen on another SDR. Even with just a power connector and no other leads connected I got this QRM. I was told this was normal and had

Re: [Elecraft] P3 Showing Transmit Signal

That would be from me… Amazingly, this was on 80 meters, and was heard all over the bay area up into central CA. At times the “echo” was louder than the direct signal! There are at least two recordings from that event. Very strange, and extremely interesting. While it was ongoing, both 40 and

Re: [Elecraft] KX3 VSWR problem (WD4SDC)

Hi John, Resonable question. The load was a Narda type N 20W dry load good from DC - 12GHz - borrowed from work;) And I did test it just to make sure someone else did not "abuse" it (bench test equipment). Also tested the N->BNC adapter. Trust, but verify your test equipmentgood advice.

Re: [Elecraft] Need a KFL1-4 Manual

Mike, I'm sorry, my two cents worth. Maybe if you asked "Nicely" where you could get one, someone would help you. I have a K1, but not a 4 channel board, so I don't have a copy of the manual. But I would like to thank everyone at Elecraft for their excellent service. Have a Happy Thanksgiving

[Elecraft] Happy Thanksgiving!

I would like to wish everyone at Elecraft a Happy Thanksgiving. One of the many things I am thankful for is my K3S. I have fully enjoyed this rig. -- ​73​ Steven Stuckey - AC9GK - Indiana __ Elecraft mailing list Home:

Re: [Elecraft] K3 / K3S Power Supply

I have an Astron though not rack mounted. It's an RS-35M and has been on for 11 years continuously save the occasional power outage. How far away from the radio position is the rack? The power cable supplied with the K3/S is about 5ft and I think #12 diameter conductor. On 11/25/2015 7:55 PM,

Re: [Elecraft] elecraft@mailman.qth.net

Your problem would have never occurred to me. I check all antenna connections and ground connections each fall. This includes the service ground for the house. No details on the how it is done - I will leave that to the relector's abounding experts. Suffice to say, a poor ground can not only

Re: [Elecraft] K3 / K3S Power Supply

I've used a pair of RS-35A for years - one is at least 30 years old and predated the K3. In all that time I've had exactly one failure - lost a diode in one of the bridges in the newer (10 year old) supply. The RS-35A is rugged and quiet (no noise like most switching supplies) - I have no

Re: [Elecraft] K3 / K3S Power Supply

I have an Astron 20 and a 35 - for over 30 years they have been running. That said, they are heavy to annually move around, clean, and check the connections - and gaining weight annually (perhaps related to my advancing age). I took Elecraft at faith and purchased the PowerWerx switching

Re: [Elecraft] K3 / K3S Power Supply

I have a RS-70A that I turned on 13 years ago; it has 'suffered' through many house power losses here in the country, but has not missed a beat over the years. Except for my amplifier, it powers everything else in my ham setup. IMO, the Astron's are unbeatable! 73, Tom - W4BQF -Original

[Elecraft] New KX3 - No SSB output

Happy Thanksgiving to all! My Thanksgiving Eve was great when the UPS man walked up and delivered the long desired KX3. I spent the next few hours putting the kit together and it felt like it went together without a hitch. I then decided to make my first QSO and wanted it to be DX so I worked

Re: [Elecraft] Need a KFL1-4 Manual

In my experience, the employees at Elecraft are in a class by themselves. Several times I have made requests for obsolete or undocumented information that required one or more people to interrupt their assigned job responsibilities and pay attention to me. In every instance they came through

What are you seeing on the ALC meter? What Mic? Sounds like you have no audio drive. Check mic settings. Do you hear your audio in the monitor? -- View this message in context: http://elecraft.365791.n2.nabble.com/New-KX3-No-SSB-output-tp7610849p7610850.html Sent from the Elecraft mailing

Re: [Elecraft] K3 / K3S Power Supply

Yep and unless they've changed their design recently, all their linear regulator supplies have as their heart, the venerable '723 chip for voltage and current regulation. If I remember correctly, that IC was introduced about 50 years ago ! I know just about everybody makes 723's now, but

Re: [Elecraft] New KX3 - No SSB output

Keith, Do you have the mic plug in all the way? Remove it and plug it in again. Did you turn on bias? The MH3 needs that to be on. Do you have your mic gain set to a high value? If so, turn it down to a low level - set compression to zero initially. Then bring up the mic gain until you see 5

Re: [Elecraft] New KX3 - No SSB output

Bob and others, The ALC meter is not moving at all...not a single bar. I am using the Elecraft MH3 that came with the KX3. I do hear myself in the monitor. I double-checked to make sure the Power Setting was not at 0I saw some blog postings around people doing that by accident. I have

Re: [Elecraft] K3 / K3S Power Supply

John, I asked the same question of the fine Elecraft folks and they recommended Power Werx. Been very happy with it for the KX3 and K3S. http://www.powerwerx.com/power-supplies/ David A., KC0XT, LA > > On 11/25/2015 7:55 PM, John Maass wrote: >> ​Seeking recommendations for a quality power

I also have an RS-70 and I think it’s been turned on even longer than that ... Recently, though, as part of going more minimalist, I put it into semi-retirement and bought the PowerWerx unit. In the shack, i’ve never heard a whisper of RF from it. But I did find that if I set the PowerWerx

Re: [Elecraft] New KX3 - No SSB output

I‘m not sure what you mean by “mic setting” at 3-5. Have you tried setting the mic gain higher? I keep mine at about 25 for the MH3. Works fine. Grant NQ5T K3 #2091, KX3 #8342 > On Nov 26, 2015, at 9:01 AM, kb3...@comcast.net wrote: > > Bob and others, > > The ALC meter is not moving

Re: [Elecraft] New KX3 - No SSB output

I think that is it! I was mis-reading the manualit is the Mon setting that should not be higher than 3-5 or you get clipping. I moved it up tp 25 as you suggest...and the ALC bars are moving. I will try to see about making a contact before the crowd shows up for Thanksgiving in a bit and

Re: [Elecraft] KX3 VSWR problem (WD4SDC)

Steve: Is it possible your dummy load is not 50 ohms at 6M? In other words, is your dummy load designed to work at VHF frequencies? Maybe it's only designed for HF frequencies. Just a thought, but it could possibly explain your problem. 73, John AA0VE Jim Rodenkirch wrote I'm not sure

Re: [Elecraft] New KX3 - No SSB output

RE:  I have the Mic setting at 4 (manual recommends 3-5).  Page 15 of the manual recommends the MONITOR set to 3-5, not mic gain.  It also says "Mic gain for the Elecraft MH3 us typically 15-25." I suspect your mic gain if set at 3 to 5 is too low. MarkKE6BB
