Re: [Elecraft] WSJT-X Problem with K3S

In MSK144 the T/R periods for meteor scatter are normally 15 seconds on 50 MHz, so it is important for all stations to have their clocks as accurate as they can, within half a second will do, but the closer the better. Just to explain further, on meteorscatter it is possible for many stations

Re: [Elecraft] WSJT-X Problem with K3S

Many thanks to all who provided their suggestions. I decided to try Joe's (W4TV) suggestion and elect RTS. That appears to have solved the problem of the transmit staying on. My only remaining problem is a 100 to 200 millisecond spillover into the next sequence. I have synched my Mac to

No slight to Joe, who knows what he's talking about, but why not use Jim's suggestion. I don't use any of the imaginary modes, but I do use VOX exclusively on RTTY and PSK. I do wish VOX gain was remembered by mode, however. Request #39. N7WS On 1/12/2017 11:55 AM, John Stengrevics wrote:

Now that the thread has morphed to RFI: I was getting complaints from my wife that my transmissions were getting into the home theater audio when she was watching TV. Specifically, it was getting into the new powered woofer. I determined this was only happening on 6m and at 1000w. So I

Re: [Elecraft] WSJT-X Problem with K3S

In that case it's probably statistically slightly more likely that a CAT command (seems like about 5 bytes) would get garbled going across the USB than whatever bit stream went across the USB to turn RTS off. One would be an op-code (probably 8 bits) plus 5 more bytes, versus the other being just

Re: [Elecraft] WSJT-X Problem with K3S

Nick, Yes, the K3S connects directly to USB, but inside the K3S is an FTDI USB to serial converter. It has the RTS and DTR signals and they are properly routed to the K3S. The RS-232 circuits in the K3S are retained just like as they were with the K3. 73, Don W3FPR On 1/12/2017 1:15 PM,

Re: [Elecraft] WSJT-X Problem with K3S

You should really do what Joe suggested. It is highly unlikely that RFI would ONLY affect the one CAT command. It more likely is some kind of timing entanglement which will be difficult to diagnose. DO try what Joe said: On Thu, Jan 12, 2017 at 1:08 PM, Joe Subich, W4TV wrote:

Re: [Elecraft] WSJT-X Problem with K3S

there is no physical RTS line involved like there would be in an old-style COM/RS232 device- there is only serial data going across a USB cable to a logical COM device inside the K3S. It most likely wouldn't change anything in this case. The physical RTS line is moved from the computer to

Correct. The K3S is connected directly to my Mac via a USB cable. John WA1EAZ > On Jan 12, 2017, at 1:15 PM, Nicklas Johnson wrote: > > Unless I'm mistaken, doesn't the K3S connect directly via USB though? If > the problem is happening because of common mode on the USB cable,

Re: [Elecraft] WSJT-X Problem with K3S

Unless I'm mistaken, doesn't the K3S connect directly via USB though? If the problem is happening because of common mode on the USB cable, there is no physical RTS line involved like there would be in an old-style COM/RS232 device- there is only serial data going across a USB cable to a logical

Re: [Elecraft] WSJT-X Problem with K3S

The other thing, too, is if your antenna is just relatively close in proximity to your shack, it won't matter how well balanced your feedline is; you may still end up with cables inside your house that are resonant at or near the frequency where you're transmitting, or at least near enough to

Re: [Elecraft] WSJT-X Problem with K3S

John, The first step to solving RF-in-the-shack problems is to work on your antenna system. Better common mode chokes on your feedline(s). See the information by Jim Brown K9YC at http://audiosystemsgroup.com/RFI-Ham.pdf. If you still have problems after taking those measures, then use

Two things: one is to go through the usual steps around keeping RF out of the shack. There are a lot of resources around this online regarding baluns, "ugly baluns" and so-on. The other thing I've done is exactly as you've said: several turns of computer cables through ferrite. Watch your cable
