I first suggest updating to the most current version of WSJT-X. On receiving FT8 signals, what is the DT time shown for most received signals? Should be less than 1 second and typically less than 0.3 seconds. If so there is nothing wrong with your computer time. Likely the delay is

[Elecraft] KPA-1500 and Remotehams.com

Hi all, I'd like to be able to use my KPA-1500 with Remotehams, but I'm not sure how to set this up. First off, the baud rate is limited in the RCFOrb server app to 115200, and secondly, I'm guessing I have to open a port somewhere?? If the only way to do this is drop the baud rate on the KPA,

[Elecraft] Time Sync Program for Mac

What’s a good simple stand-alone application to keep my Mac’s clock razor sharp for FT8? I find that WSJT-X 1.8.0 is triggering my K3S’ transmitter up to a full second late sometimes, typically 0.5 second late. Cheers! Richard — W4KBX

I didn't find the answer in the manual, so I'll ask here.   I do see in the manual where bleed resistors are applied to the unused antenna terminals to bleed off static charges.  {page 15, Antenna Selector. etc} My question, do the relays in the tuner take the center conductor of all

Re: [Elecraft] loss of RX sensitivity

If you have a vector network analyzer you'll discover that BNC connectors aren't all that great at VHF and above, l oss and impedance vary with connector axial alignment because the bayonnet shell doesn't support aligh the connector body very well. Strain relief is extremely important with BNC

Re: [Elecraft] loss of RX sensitivity

Pretty much my point made in another post. In fact, I often take a perverse view of these situations and ask myself, "Self, if you wanted to screw these two things together without the faces touching, how difficult would it be to do?"  And of course the answer is, almost impossible. Wes 

Re: [Elecraft] loss of RX sensitivity

This is one of those, "it depends" situations.  Depending on the location of the two center conductor insulators in the plug and socket, the serrated (toothed) surface of the female connector might well contact the mating plug surface, if there is a gap between the insulators. In fact the

Re: [Elecraft] loss of RX sensitivity

Andy, The PL259 to SO239 connector "end face" contact is provided only by pressure - it is not a sliding contact as you would find in a BNC or an N connector. The pressure is provided only by the tightening of the threaded portion of the PL259. I ask you - just how much resistance can be

[Elecraft] loss of RX sensitivity

" the threads of the PL259 are providing the only contact with the SO239" In the connectors that you are mating how do you prevent contact between the end face of the PL259 body and the end face of the SO239 body? You would need an insulating spacer for your statement to be true. 73, Andy

Re: [Elecraft] loss of RX sensitivity

Chuck, That is true, but is ignoring the fact that the threads of the PL259 are providing the only contact with the SO239. They must be solidly tight for reliable conductivity to the shield of the coax. All contact from the SO239 to the coax shield is by pressure contact. Finger tight may

Re: [Elecraft] loss of RX sensitivity

I've found that wiggling the body of the plug while tightening the threads makes the pl259 quite tight with the pins firmly seated in the notches. The motion allows the pins to find the deepest well of the notch. Chuck Hawley c-haw...@illinois.edu Amateur Radio, KE9UW aka Jack, BMW

Re: [Elecraft] loss of RX sensitivity

Yes, regardless of how good they look, always snug the PL-259 with a small pair of Channel Lock pliers. Finger tight is not good enough. Many of our connectors today are of inferior quality. Also due to the use of jumpers, the flexing and pulling is prone to damage the connection between

Real easy to see on a spectrum analyzer with a tracking generator. The trace goes wild as soon as you start turning the PL-259 connector by hand (please don't use pliers on your SA). 73, Ian N8IK On Mon, Sep 17, 2018 at 12:59 PM, Don Wilhelm wrote: > Drew and all, > > I beg to differ, unless

Re: [Elecraft] loss of RX sensitivity

Drew and all, I beg to differ, unless you meant something different than I read. The threads on a PL-259 connector are the only thing that connects the coax shield to the SO-239 jack. That is why hand tightening of PL-259 connectors is not sufficient. Use pliers to snug them up just a bit
