Re: [Elecraft] [K3] [P3] IF Out / IF In Cable

Wrong use of 75/50 ohm cables is a cause of unreliability on scopes: they're 
made for 75ohm connectors and if you plug in a 50ohm plug is will eventually 
splay the centre contact and cause intermittency.

 Yes, the cable impedance does not matter but the connectors do.  The
 75-ohm cable probably has 75-ohm BNC plugs, which as I recall have a
 smaller pin.  They might not make reliable connections with the 50-ohm
 sockets on the K3 and P3.

 Go ahead and try it, but if the connections seem flakey you should get a
 real 50-ohm cable.

[Elecraft] [K3] Internal 2m module

2012-09-17 Thread Kjeld Holm
Dear Elecrafters,

 

Tnx to all who responded.

 

Your/my conclusion was that I needed also K144RFLK that locks the
transverter to the TCXO in the K3 for stability on CW and SSB.

Re: [Elecraft] [K3] [P3] IF Out / IF In Cable

2012-09-17 Thread Jack Smith
There seems to be confusion over 50/75 ohm connector mechanical 
compatibility.

50 and 75 ohm N connectors are not mechanically compatible as the center 
pins are different diameter--50 ohm has larger pin diameter. Over time, 
a 50 ohm N male connector can damage the 50 ohm female N and a 75 ohm N 
male may not make reliable contact with the 75 ohm female N.

However, everything I can find in terms of published dimensions, 
specifications and measured diameters says that BNC pins are of 
identical diameter in 50 and 75 ohm variants. The difference in 
impedance seems to be handled in the dielectric dimensions and material.

Many HP 75 ohm BNC connectors, for example, have no plastic dielectric 
at all in the female version--the center socket fingers have nothing 
supporting them but air.

It may be that in ye olde days of the early 1940's when the BNC was 
invented pin diameters differed, but if that was the case then, it seems 
to have vanished in the last few decades.

be a bit better if a series diode in KX3 is removed that adds about 0.6V

[Elecraft] MIL-STD 348B BNC Dimensions

2012-09-17 Thread Jack Smith
MIL-STD 348B (3 Feb 2009 edition) contains the reference dimensions for 
RF connectors meeting US military specifications.

The center pin diameter for 50 and 75 ohm BNC male connectors are 
defined in figures 16 and 85 respectively. In both drawings, dimension 
D is the pin diameter and is (min) 0.052 [1.32mm] / (max) 0.054 
[1.37mm] diameter in both Figures 16 and 85.

In the absence of definitive information to the contrary, this should 
remove any doubt that 50 and 75 ohm BNC center pin diameters are 
identical, at least if they are made according to MIL-STD 348B.

Some offshore manufacturers seem to regard specifications are advisory, 
not mandatory, of course.

The cable you reference is built with RG59 (75 ohm) which should put to bed

Re: [Elecraft] [K3] [P3] IF Out / IF In Cable

 Personally I don't want a 75 ohm cable in the shack where I might use it on

There are times when 75 ohm cable is preferred, regardless of the rated 
load impedance of the rig or power amp.  A high dipole (as a fraction of 
a wavelength) is a closer match to 75 ohm cable than to 50 ohm cable. 
Excess loss in the coax due to mismatch is determined by the match 
between the antenna and the line, NOT between the rig and the coax, 
although some matching may be required at the rig to keep the output 
stage happy and transfer full power to the load. In addition, because 
the current in 75 ohm coax is one third lower for the same transmit 
power as in 50 ohm coax, 75 ohm coax of equivalent size and construction 
typically has a bit less loss than 50 ohm coax. The 80/75M band has a 
bandwidth of nearly 10%, so 75 ohm coax provides lower SWR on a high 
dipole over a greater bandwidth.

Yes, it's wise to be aware of cable impedance so that we're not 
generating mismatches by inserting cable of the wrong impedance, but 
don't throw the baby out with the bathwater. :)  I use mostly 50 ohm 
coax, but have at least 300 ft of Belden 8213 feeding my two high 80/40 
dipoles, and several resonant lengths of CATV hard line feeding my 20M 
and 15M yagis.

There are also some really neat broadband matching tricks that one can 
play with resonant lengths of 75 ohm cable. I'll be talking about that 
at Pacificon Antenna Forum next month.

[Elecraft] KX3 a teacher for the K3...

2012-09-17 Thread Phil Townsend
The KX3 has really helped me learn the ins and outs of the K3.

The K3, I was able to run it and make contacts but it is such a large body of 
work it has taken me along time to get it.

The KX3 for some reason really helped to put the K3 into perspective. Really 
helped... s

Would I buy a KX3 to learn the K3?

Sure...

But then I think the KX3 it so cool, It simply had to be designed and built in 
Calif. Santa Cruz no less...

[Elecraft] [KX3] KXPD3

How did field testing of the KXPD3 paddle upgrade turn out? I'm about to pull

Re: [Elecraft] [KX3] KXPD3

2012-09-17 Thread Thomas Horsten
Hi Robert,

I posted two updates, one just after I got the KXPD3 upgrade kit and
another after I'd used it for a couple of days. These were posted on the
KX3 group (join if you are not there already, most of the KX3 talk goes on
there). Anyway, for those of you who haven't seen it, I'm copying the two
updates below:

Hi all,

I received the field tester upgrade kit this morning. It took about 10
minutes to install. The only problem was the size of the screw hole in the
PCB was a bit tight, but I didn't need to drill as long as I carefully
tightened each of the mounting bolts one turn at a time (this is a known
problem and will be fixed in the final version).

The kit consists of a new PCB with stainless steel fixed contacts, new
contact screws with rounded ends, and two alternative springs to choose
from with lower tension than the original.

I selected the lowest tension spring and set the contact spacing at three
quarters of a turn from the inner (fully closed) position.

The paddles feel completely different. I tried sending some of the text
from the upgrade instructions and didn't have a single missed dit or dah,
and both the spring resistance and the crispness of the action is improved
by an order of magnitude. I wouldn't say it rivals my Begali Sculpture but
it is much closer to that feel than it was before.

Now I just hope it stays that way, I guess with a portable rig, dirt on the
contacts will be a bigger issue than for a home key, but out of the box, no
complaints at all, thanks to everyone at Elecraft, you've done a great job.

I did a video of my upgrade, but unfortunately my phone ran out of memory
after 5 minutes, so the most interesting bits didn't get recorded. Maybe
I'll post it anyway just to show the unboxing and the kit content.

WX for the weekend is looking like we're in for a bit of Indian summer,
with full sunshine and 27C, so I hope I'll be able to get some outdoor
operating done with the KX3, maybe a WFF activation on Sunday. I'll report
back after a while and see how it goes.

73, Thomas M0TRN


After posting my first impressions just after the upgrade, I've used the
upgraded KXPD3 for several real QSO's and I wanted to give an update.

My KXPD3 already had the PCB mod performed which had greatly reduced the
intermittent contact problem. So I didn't expect the upgrade to make that
huge a difference (only compared to the unmodified PCB which was pretty
horrid in this respect).

But I actually find that the upgrade kit does far more than that. It takes
the key and transforms it from a sub-Bencher feel to a near-Begali feel.

To get reliable operation on the paddles before, the contact spacing needed
to be over 1mm. I think the main reason was the shape of the end of the
contact screws. Per the suggestions previously made on this list, I'd tried
filing down the ends of the contact screws to get them more rounded, but I
hadn't done a very good job at it. The new contact screws are stainless
steel and already rounded from the factory. Also the contact posts are now
stainless steel as well. Finally, the spring tension was too high for
comfortable operation at a very low spacing.

So the spacing needed to be at least 1mm or so for the key to be workable.

It's probably down to a combination of all the upgraded materials,
including the lower tension contact spring, but the key works perfectly now
with sub-mm contact spacing. I am using a spacing of about 0.3-0.5mm, which
corresponds to about three quarters of a turn of the contact screws, and
have locked them in that position. This, in combination with the lowest
tension spring, gives an unsurpassed feel that I have only before
experienced in my Begali Sculpture.

I can now send clean code at 35 WPM with these paddles, something that was
unthinkable before. Although most of my QSO's are at 25 WPM, it is nice to
be able to send QRQ when the opportunity is there, and that's now possible
with the KXPD3.

The only thing I am missing slightly is individual tension adjustment of
the left and right paddle. Since I use paddles with my left hand (but in a
default configuration with dits on the left), I tend to use my Sculpture
with a slightly higher spring tension in the left paddle. But in such a
tiny key I wouldn't expect that.

In short it's now a paddle that works extremely well and where the
precision label is 100% justified. To be honest I thought that  was
stretching it a bit in the original incarnation of the KXPD3.

[Elecraft] laptop power supply to power KX3

2012-09-17 Thread Jeff Herr
While at work I went through our stock of power supplies for the various
makes of laptops we use.
I found that Toshiba supplies are specified 15v and ranged in current
capability from 2.5 amps and up.

Dell, Lenovo, HP, Acer, Asus all use 19v supplies.

Those Toshiba supplies are very small.

[Elecraft] KX3 - Reminder - Special Event Station K2N on Wednesday 19 September

2012-09-17 Thread stan levandowski
We'll be operating three (3) KX3s from Radio Central aboard the historic 
USS SLATER (DE-766) on Wednesday 19 September, from 1600 UTC to 2400 
UTC.

We're calling it the QRP CW DE-Xpedition.

Full details, participants, frequencies, QSL info are under callsign K2N 
at qrzed dot com.

We'll be using the SLATER's authentically restored shipboard antennas - 
one KX3 connected to an 80 foot vertical on the starboard side for 20 
meters; one KX3 connected to a 70' vertical on the port side for 17 
meters, and one KX3 connected to a 190' long wire running amidships to 
the fantail for 40 meters.  Our counterpoise is a 1200 ton warship 
sitting in the Hudson River at the Port of Albany, New York.

An unexpected surprise was to have Piero Begali ship us four 
pre-production Adventure paddles to put through their paces - two dual 
lever iambic versions; two single lever mono versions.

I've had the mono version here at my shack for a few days now, for 
*practice* ;) Sorry but no pictures and no product review from me. 
It's not my place.

Let me just say this:  WOW-- its graceful lines, its creative design, 
its diminunitive size, its sturdy construction, its crisp action, its 
Begali feel.WOW!

It's going to be very,very difficult to say goodbye to this 
KX3-friendly paddle on Wednesday night.

On Thursday morning, I will begin siphoning off dog food money and 
grocery money so I'll be ready to purchase one when they go into 
production!

Hope to work many of you on Wednesday,

 This is a QRP event using the SLATER'S maritime antennas and a 1X1 call 
 of K2N.  We have some fun, call attention to a historic ship, and call 
 attention to QRP ham radio operations all at the same time.  And we made 
 up our own QSL card.
 
 Exactly as advertised on qrzed dot com under K2N - truth in 
 advertising
 
 Where's the problem?

 Historic the ship is, but ham radio operating from it is *not*, unless 
 the
 authentic original naval communications equipment is being demonstrated.
