Re: Best way to wire 2 wires from Molex into 1 in a Powerpole (WAS: Need mating connector for Kenwood PS-30 power supply)
It's always better to use a larger gauge than smaller, Don.? I would combine the two connections at the radio end of the cable.
The "standard" APP accepts 15A, 30A, and 45A pins.? I always use the largest pins (45A) for transceivers and the smaller ones for accessories.? I have an adapter made for the IC-7610 with a pair of fuses, APP plugs on one end, and splices to the Icom-supplied power cable.? The adapter manufacturer used #12 wire.? In FT8 use, that wire heats up but Icom's cable (perhaps #10) does not.? Heat is bad!? My project list includes replacing that adapter with one using #10 wire.? BTW, the crimped butt splices do not get warm.
There is a lot of Amateur Radio "advice" around.? Much of it is bad because it's based on anecdotes, not science.? The worst of it is about antennas.? My advice to posters here is to confirm you assertions with multiple trusted sources before posting.? Let's at least slow down the proliferation of bad advice, if not kill it altogether.? Excellent mentors know when to not provide their anecdotes unless they label them as such.? That's the difference between facts and opinion.s

Re: Need mating connector for Kenwood PS-30 power supply
PowerWerx sells all three versions of APP pins (by Anderson) separately from the housings.? Two seconds on Google (typing and the responses) finds this.? I will never buy non-Anderson APP stuff again!? Like in many applications, "cheap" is often more expensive in the end.? Cheap hams (sorry for the redundancy) usually spend more and waste time in the end.

Hi? Donald Hellen,You need this cable: Donald Hellen < donhellen@...> escreveu no dia sábado, 6/08/2022 à(s) 21:31:
I may have found one for less, a pair of matching ones but it looks like it has
the correct female. Can someone verify this is the matching one?
Also, would it be a good idea to get a Molex crimp tool? I've used long nose
pliers before but it doesn't do it neatly. I plan to solder the 10 or 12 gauge
wire to the connector then to Anderson PowerPoles on the other end. I do have a
PowerPole crimper. I just have to hunt it down.?

Re: Need interface cable or instructions on building one
Here's a simpler interface. Like it says in the text, you can choose other transistors to handle the voltage and current. Here's the link...
Let me know how it goes. Bob. W4JFA On Sun, Aug 7, 2022, 11:34 AM Wayne Carpenter KN2Z 21-215F @minicowman via <mwcarpe= [email protected]> wrote:

Re: Need interface cable or instructions on building one
Awesome! Thank you Bob!? I can certainly give that a try.. and I might even have both of those semiconductor items on-hand.. If not, I know where to find some. As I mentioned, I have the manuals/schematics for both the radio and the amp so verifying pin IDs shouldn't be an issue.? I'll post here when I have it ready to try out.? Thanks again.

Re: Best way to wire 2 wires from Molex into 1 in a Powerpole (WAS: Need mating connector for Kenwood PS-30 power supply)
I have a Kenwood power cable that is factory made and has the two wire cable from the Molex to the power supply. There are also line fuses in each wire of the cable. I was able to slip the boot off of the Molex connector and see how they connected the #10 stranded cable to the Molex connector. There are NO solder joints.
The black and red wires were separated about 2-1/2 inches back from the cable end.
Each wire was stripped back about 2 inches then the strands of each wire were divided into two equal smaller twisted wires. That now makes a red wire with two stranded bare twisted wires about 2 inches long and a black wire with two stranded bare twisted wires about 2 inches long.
The connectors were then crimped onto the 4 wire ends. Heat shrink was placed over each bare wire and shrunk. Another short piece 1/2 inch long was then placed over the 2 smaller heat shrink and the wire insulation to cover that seam and then shrunk.
Of course, the boot is factory molded but that covered all the heat shrink and Molex connector. As far as a final cover for your installation that is your choice of materials.
Hope this helps. The cable has worked fine for me and has been safe.

handle the current (it's a bit much for a single pin to handle). The Powerpole

two Molex pins for each polarity into a single connection on the Powerpoles.
Is it best to use two smaller gauge wires from the Molex and run them both into
one Powerpole, or use a crimp connection to merge it into a single 10 gauge wire
(it might be 12 gauge). The thicker wire would go into the Powerpole. I could
also solder a Y together and do it that way but it adds a soldered connection in
the middle between the Molex and Powerpole connectors.
I don't see a problem with using a butt splice connector but technically these
are made for one wire into each end. Would a crimping of two smaller wires be
good enough on one end of the butt splice?
This isn't likely to flex much in operation, but I might as well make this work
as well as possible and make it look professional.
I still need to hunt down my Powerpole crimper but I am not in any hurry.

Re: [Amateur-repairs] Need mating connector for Kenwood PS-30 power supply
Thanks for the warning. It would be easy to put the wrong ones in. I don't know why the typical installation wasn't female pins in the female connector shell and vice versa but that seems to be the usual way to doing it (the way you said). What's really confusing is that there are so many different combinations of squares, rounds, and Ds to prevent plugging the wrong ones together in a production line but it sure makes it confusing to the end user trying to repair things.

Re: Need interface cable or instructions on building one
I built this for a Henry amp to Kenwood TS-850 and TS-870. There's a pin on the "DIN" socket that has 12 volts (power supply voltage) on transmit. Pin 7 in my case. Use that and ground. Pin 7 (in my case) has a maximum current draw of 10mA. This circuit draws just under 4mA on transmit. You need to verify the pin number and maximum current draw for your radio. My Henry amp has a spike of over 200 volts when TX relay disengages. That's why that darlington was chosen. If you build this you can test it with 12 volts DC and verify current draw etc before you connect to your radio and amp. Bob.

Re: Need mating connector for Kenwood PS-30 power supply

I agree with Bill.
Crimped connections can last much longer. Solder joints tend to concentrate flexing in a very small area. Don't use solder where any flexing is at all is expected. Use the proper crimping tool and use it correctly. Poorly crimped connections cause a lot of problems. If I recall correctly, (unreliable) the pins of a molex require a special crimper. A regular electricians crimper might make a mess out of those pins. Perhaps someone here has a more trustworthy memory. :)

?
Wrapping tape around a plug and socket is very poor practice if used to provide physical mating strength.? Again, professionals never do this.
?
Having worked in commercial broadcasting, as well as military communications maintenance, many in those fields won't hire the average ham for the above reasons--sloppy and unprofessional practices.? There is no good reason (except for temporary expediency) to use such practices.? All of us Amateur Radio operators can be professionals in our chosen avocation.? I encourage all hams to search for and achieve excellence.? If we invest hundreds and even thousands of Dollars in our stations, a few more for proper tools and even connectors will bring us reliability and even pride in our accomplishments.

Re: Need mating connector for Kenwood PS-30 power supply
HI Donald,
If you're not going to use it with an original radio directly, why don't you
cut it off and put the Anderson Powerpole directly onto the lead out of the
power supply. You could chop it off a couple of inches from the connector
and then use an Anderson Powerpole on it so that you can later use it on a
radio again.
