When I use PP's for any other voltage or reason the 12V power, I put the
together in a different configuration. If the pair are at right angles to on another they won't go together with the standard formation.

When you're displaying Date or time or whatever (there are several other
things that can be shown in DISP mode). Simply turn the VFO B knob to change to the other values... The K3 is VERY consistent in that if something is displayed in the top line of text the VFO A knob adjusts it and if it is displayed in the bottom line of text the VFO B knob adjusts that. ~Brett (N7MG) On Mon, 2010-06-28 at 10:56 -0700, [hidden email] wrote: > So - I had my new K3 out at our Field Day (W7S - Sammamish ARES/RACES > Group) operation; and it worked great!

That's never safe.
The safe thing to do is to use HV connectors that cannot physically plug into the LV socket. My 24V connectors from power sources are all physically larger than my 13.8 v connectors. 73 Tom ----- Original Message ----- From: "Eugene Balinski" <[hidden email]> To: "Grant Youngman" <[hidden email]>; "Elecraft Email" <[hidden email]> Sent: Monday, June 28, 2010 12:25 PM Subject: Re: [Elecraft] Power Poles... > One method to avoid confusion is to use different color > power poles for different supply voltages red-black for > 13.5V, green-black for 24V, White-black for 5V, etc > > Many sites sell the various color options. > > 73 > K1NR > > K2 SN 6k... > > > On Mon, 28 Jun 2010 10:48:20 -0500 > Grant Youngman <[hidden email]> wrote: >> That was the point. >> >> The other point was -- How hard is it to build a power >> pole connector, put it together properly, and LABEL the >> darn thing to avoid disasters like plugging a 24v supply >> into a 12v radio? :-) >> >> Grant/NQ5T >> >> >> On Jun 28, 2010, at 10:38 AM, Tom W8JI wrote: >> >> > >> > ----- Original Message ----- From: "Grant Youngman" >> <[hidden email]> >> > To: "Elecraft Email" <[hidden email]> >> > Sent: Monday, June 28, 2010 10:29 AM >> > Subject: Re: [Elecraft] Power Poles... >> >> It would also be simple enough for the manufacturers >> to solve the polarity problem by using a bridge rectifier >> at the power input, although that has a definite downside >> as well. >> >> >> > >> > It sure does have a downside.

Labeling is a good idea, and probably not become a potential for an
error if your station is static (you assemble it and never make a change). But someone like me that is always building/modifying/rearranging the hookups, labels (alone) will not prevent an "accident". I run my 28v power to a separate barrier terminal strip from the 12v distribution, and make it a 100% process to always measure the voltage of a new connection with a vtvm before connecting to the equipment. Same rule for making new cables (check polarity and continuity before use). But realizing that I am "human" I used distinctly different connectors for running HV and other level voltages. Never use a RF connector for dc. So my 3.6 kV PS cannot physically be connected to the wrong connector (they look like BNC but are MHV and will not mate). Lots of caveats in construction philosophy! Another thing I am doing these days is making connection diagrams and schematics for everything. I keep them in a master drawing 3-ring notebook so always handy for a moments reference if I have a senior moment and do not recall exactly how it is supposed to go. Very handy in troubleshooting when stuff doesn't work. I operate 16-bands 600m-3cm, 17-antennas, three towers, and one dish (If I have counted correctly). I have 26 coax connections to outside the shack.

Anderson does make a "retention clip" that snaps into the alignment holes that would be otherwise used for the roll pins. Might solve the issue you are having.

John, If one has to tape them together, the most likely problem is that they were not assembled correctly. Properly assembled APPs are very good and have an adequate amount of pullout resistance. The specification is 25 lbf - so yes, they will not withstand a 25 pound pull force, but that is quite substantial - at anything below that they should stay together. I have never had any problem with them, and I use them on all my DC connections. 73, Don W3FPR John Ragle wrote: > Aside from "Polish Solidarity" this long string of emails about the > Anderson variety only confirms my experience-based opinion that these > connectors are very poorly designed and should be avoided.

I have a 3x2 set for the control head in the car, and I found out the hard way that looking at them the mating ends have to be as follows: One set: 1-2-3 The other set: 4-5-6 4-5-6 1-2-3 For sanity's sake I use six colors and of course have the R/B placed for use with a standard APP-equipped 2-wire power cord if necessary. -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Remember that a standard is only what one designated it to be. Once, it's accidental. Twice, it's a custom. Three times, it's a standard. Four times, it's ordained from on-high. -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

If you don't feel a click when you put two together something is wrong. I use them with my rigs as well as my electric powered remote control airplanes. My biggest plane generates about 7kw (7000 watts) of power and significant g-forces while flying, never a problem.
