Re: [Elecraft] Antenna Question

One way to do it with a single piece of stiff coax is to place a standoff about a foot long above and below the rotor. Then form the coax into a spiral of several turns between the standoffs. Rotation will just tighten or loosen the spiral and not stress the coax at all. The standoffs also take

Re: [Elecraft] Interlocking two K3

The simple fix is to move the 470-ohm resistors to be inserted between pin-1 and Pin-7. The resistor is used to limit current draw when pin-7 is grounded (inhibiting Tx). With pin-10 directly connected to pin-7, pin-7 will go directly to low when pin-10 does. If you want a little more

Re: [Elecraft] Interlocking two K3

The time that the lockout of both transmitter is quite short, in milliseconds, so the solution to that problem is for the first operator to recognize that condition is to stop and then start again. It should not happen frequently. 73, Don W3FPR On 10/8/2016 12:59 PM, irdixon+lists wrote: Hi

Re: [Elecraft] Antenna Question

I use LMR400-FLEX for my rotor loops and have had no problems. It has been up since 1999 or 2000. LMR400-FLEX is the designator for the stranded center conductor version. I also have used Davis FLEX LMR400 equivalent and if I remember correctly Davis-FLEX that is what is stamped on the feedline.

[Elecraft] K3S Time Display Bug

It turns out that at least on the K3S, if you stay on one frequency for a long time, with the time showing in the VFO B area, that displayed time drifts slower and slower, losing 8 to 10 seconds (or more) over an hour. This isn't RTC drift -- the RTC is fine -- it's the way the display

Completely agree. If access isn't a problem and the additional loss of more flexible cable is tolerable, that's a great solution. I haven't used Davis Bury-FLEX but heard very positive reports about it. 73, Josh W6XU On 10/10/2016 6:21 PM, Bob wrote: For sure a consideration.There never

There is a stranded center conductor version of the LM400, do not remember what the designation is. I plan to use some for the same reason, going around a rotor to a HexBeam. 73, John WB4UHCK3 #2165 On Monday, October 10, 2016 6:16 PM, "hsherr...@reagan.com" wrote:

Re: [Elecraft] K-pod SSB macro

I use 2 "M buttons" for Data A and RTTY. Like you I use the other two for CW and SSB. Another hack that might work is to set the mode to CW and then use a macro to "press" the mode up button to switch to whichever of LSB and USB was last used. 73 Bill AE6JV On 10/10/16 at 5:32 PM,

Re: [Elecraft] K-pod SSB macro

pjd, No command that I know of, but let me offer a compromise being a combination of the M1-M4 per band memories and the Macros that are fired from the K-Pod. The closest thing I can think of is to set up the M1-M4 memories for each band. I use M1 for CW mode, M2 for data mode, and M3 for

Re: [Elecraft] Antenna Question

As is military practice as well. If you really want to get picky, the 400 should come up to the connector [sealed of course] and supported on the tower, and then the jumper forms the drip loop to prevent water running down the coax from running over ... and eventually into ... the connector.

Re: [Elecraft] Antenna Question

With an unbroken feedline, a failure or antenna swap can require soldering connectors up the tower. Not fun. If you're concerned about the additional loss of a barrel connector at 50MHz, you should be using feedline with lower loss than LMR400 up the tower. Wrap the barrel connection with good

Re: [Elecraft] Antenna Question

You'll get lots of suggestions, but I believe the use of a single unbroken feedline from the antenna to the shack (when possible) trumps the inconvenience of properly engineering an install that does NOT put unnecessary repetitive bending moments on the line. Do the research There's all

Re: [Elecraft] Antenna Question

LMR400 is really stiff. When I used it as a rotor loop, I made a couple of hoops around rather than directly flexing the cable around the tower. Not sure if that makes sense. In any case, doing it again I would definitely use a more flexible jumper for the rotor loop running to the antenna. In

I don't know the suggested turning radius of LMR400.  In my system I use about 6 foot jumper of RG213 to do the section around the rotating section.  I use a KLM 8 el and the total length is longer. Mel, K6KBE From: John Stengrevics To: hsherr...@reagan.com

OK all. I'm installing a 6m rotating beam and feeding it with LMR400. Would you connect the LMR to the antenna and allow it to move with the rotation, or run a short length of something much more flexible between the antenna and LMR? I have my concerns that the solid heavy inner conductor of
