Re: [Elecraft] CW Monitoring

If you want to quantify the CW element lengths and timing as they appear in the sidetone audio try an app called Precision CW Fistcheck. It displays a graphical representation of the individual code elements. 73, Drew AF2Z On 09/23/15 15:10, David Bunte wrote: A friend is having an issue

Re: [Elecraft] experience with CW and settings

Two more items to keep in mind from another (semi) rural resident: 1) Power pole lightning arrestors can deteriorate or be damaged by a strike and cause leakage/arcing. (Note that the noise from this can be intermittent rather than constant.) That happened on a pole near me. I walked around the

Re: [Elecraft] K3S proper grounding?

Is a Direct TV / satellite receiver involved? I have experienced RF getting into the Direct TV / satellite receiver causing it to change channels, turn on and off, and reset. It is the fact you are radiating RF which is the desired intention and this RF is getting into the "plastic box" of

[Elecraft] Fwd: Re: experience with CW and settings

Al's point is very well taken. I've encountered more than one device that is "Part 15 Compliance", when indeed measurements confirm it only has the "Part 15 Label". With companies performing self certification, first there is no assurance the results are accurate and second, manufacturing

Re: [Elecraft] K3S proper grounding?

I had the same problem and it occurred on 40 meters regularly as well. Low power (~80 to 100 watts) did not seem to bother the TV but it was a regular problem at power’s much over 100 watts. My solution which seems to work flawlessly so far with max power of 600 watts is that I took a whole

[Elecraft] K3S to P3 cable

Need a schematic of CBLP3Y cable. K3S comes with E980297 cable (RJ45 in K3S to RS232 in P3). Now the need is connection between those two RS232 to P3 (PC and XCVR). No point in ordering CBLP3Y cable. Price 30$ is OK, but postage 50€ is not. BennyOH9NB --- Avast Antivirus on tarkistanut

[Elecraft] K3S proper grounding?

On 40m my TV turns off and on by itself when I transmit. I'm thinking that it's related to grounding because I've not figured that out yet. I have a roof mounted mast that holds my dipole. The coax comes down through the roof, routes through the attic down inside the wall to the station. I've been

Dale, if you use a handheld that can do AM on VHF or UHF and walk the fence you will find it pretty easy to locate the bad joint(s). Once they are fixed the noise goes away. For Wire fences I put a little grease on the join after I remake it to discourage future corrosion. For tape and string I

Re: [Elecraft] K3S Proper Grounding

You might just add a 0.05 mf 600V capacitor between the black to ground and a 2nd one from white to ground at each light. Likely the Romex comes into the box and the lamp is wire nutted on. Should be pretty easy to figure out how to install a couple of bypass caps. Before working on this,

Instead of a clip-on ferrite, if you're going to have the box open anyway might running the hot and neutral through a small ferrite (core or sleeve), or in addition to the bypass caps, possibly correct the problem? 73, Al On Sat September 26 2015 7:22:23 pm Bob McGraw - K4TAX wrote: > You

[Elecraft] K3S Proper Grounding

My problem with stray RF isn¹t the TV or other electronic appliances, but with the exterior motion sensor lights. 500 Watts on 20 meters turns one of the three pairs on (always the same one). Since they are hard-wired into the house, clip-on ferrite would be hard to do. I can live with it if I

Re: [Elecraft] K3S proper grounding?

I would think it is more related to the susceptibility of the TV to RF than to any grounding issues. You could try ferrites on the TV power and all other cables. 73, Don W3FPR On 9/26/2015 1:41 PM, ae...@carolinaheli.com wrote: On 40m my TV turns off and on by itself when I transmit. I'm

Re: [Elecraft] K3S proper grounding?

The problem has nothing to do with grounding. RF is getting into the house wiring. I suggest adding a choke balun at the feedpoint of the antenna to reduce "RF in the shack" and wrapping the power cord of the TV around a ferrite rod, toroid or bead for several turns. Google K9YC's RFI

[Elecraft] KX3 programming question

Re: [Elecraft] Connections for K3S, P3 Revisited

Be sure the RJ-45 portion of the K3S<->P3 "Y" cable is fully seated. Sometimes the rubber boot slides a bit on the connector and it appears to be fully mated, but isn't. It must be seated until the plastic tab on the RJ-45 clicks. There is a jumper connection in the RJ-45 connector on this

Re: [Elecraft] Connections for K3S, P3 Revisited WORKAROUND

Byron, The way you have it connected now, you have to use two "COM" ports, one for the K3S and another for the P3. It would be better to use only one. Since you have a USB to serial adapter working with the P3, I suggest you remove the USB cable (unless you are using the internal K3S

[Elecraft] K1 Initial Build, no LCD, but will display version on power up -- FOUND IT!

The issue turned out to be an OPEN RFC6 on the RF board, so no 6v to the RF board. I suspect that the Key In line (powered through a voltage divider) or some other line was presenting something the CPU couldn't deal with (algorithmically). Careful measurement of all of the voltages pointed us

I found a workaround by using the Elecraft RJ-45-to-Serial cable and a separate PC-to-P3 USB-to-serial. I am uncertain how to test the RJ-45-to-Serial cable, but at least it no longer "breaks" my K3S to PC USB. Data Terminal Mode in the P3 seems like a secret, but I'm hunting for it now. 73,

Good advice, both on the caps and pulling the breaker and checking that it's dead. Of the 38 24 VAC irrigation valves I had [before we sold the farm], 6 were directly under my low band sloping V and I turned them on and off at 30 WPM which is not an approved code speed for Irritrol valves.
