Re: [Elecraft] KX3 2m external amplifier

[Edward R Cole]

Thanks to Mike and Bill for buying my 2M80 amps (assembled or partial 
kit).  I built twelve amps so far and most were to be driven by KX3's 
with 2M module.  I set nearly all amps to be driven by 1.5-2.0w so 
the KX3-2M would not have to run full power.  The 80w RF module that 
is used is not in production so now limited quantities available 
(from RFParts).  I have identified a replacement power module which 
should run 60-70w.


But there are quite few surplus 2m linear amps available.  Mirage, TE 
Systems, and RFConcepts.  I have a RFC 2-23 linear which runs 2w/30w 
and RFC 3-17 linear which runs 40w/170w.  I have three 2m sources: an 
old FT736R (30w), DEMI 28-144 HP (50w) and the KX3-2M which not up to 
stuff running only 1.5w.  I use either the RFC 2-23 or a surplus MOT 
amp that runs 1w/60w (FM) with my KX3-2M.


I am not taking orders for a couple months as I am working on some of 
my own projects while summer wx is still here:
6m 1kW amp and possibly building a new 18x26 foot ham shack which 
will require running all new cables to my four towers and dish.  Take 
a look at the amps here: http://www.kl7uw.com/kits.htm

Ed, KL7UW, built me a nice 80w 2m amp for less than $400.

[Elecraft] Macro help

[Leroy Marion]

I am having some success with the  Kpod marcros.   I have read thru the
programing reference

 

But still need some help I am a macro beginner. 

 

1.   What would be the one tap turn on the diversity one hold same
button turn it off macro. I can make it do it but it does not turn off the
SUB RCVR when I use mine. I am trying make one that does not change the VFO
frequencies as well. Just enable diversity/return to where it was.

 

2.Can one tap/hold the Fine/Coarse VFO resolution.

 

 

 

My others seem to work OK, so if someone can help with these two I
appreciate it.

Re: [Elecraft] KX3 2m external amplifier

[Tim Tucker]

You can call the owner and talk to him yourself and make your own
determination on where they're made.  He has his name, address, and email
address right there - email and ask for his phone number.  I know quite a
few people (including myself) that have purchased several of those power
supplies direct from him and have not had any problem with RFI.  I have
also purchased one of the chinese versions that look the same and threw it
out almost immediately because it was so bad.  If you bought one direct
from him that was noisy, I'd call him up and send it back for him to
replace to test out his advertised 2 year warranty.

While I don't doubt that you're successfully using these, I previously 
looked into these supplies and find the claim that they are made in 
California to be highly questionable. At the least, I don't see where 
the products are marked "Made in USA" nor does it say this anywhere that 
I can find on their web site. They refer to copies as "offshore clones" 
and so on, but no where do they refer to their own supplies as made 
here. Selling 30A supplies for $50 full of hand inserted through hole 
components, it seems frankly impossible that they are manufactured using 
California labor.


If you have information to the contrary, please post as I'd love to be 
wrong. Since we all own Elecraft gear, I'm guessing that many have the 
same strong preference for USA made products that I do.

Thanks Jim...  I was going to try one of those to test the claims
made...  Even had someone offer to pay me my cost +$10 if I decided I
didn't want it after testing...

The business owner claims they are "quiet" and says there are
"counterfeits" being passed off as "his" power supplies.

Really would be nice to have a SMPS that was quiet, modular, and able to
be put in parallel for more power out...

[Elecraft] Great KX3/PX3 Covers

[Larry D. Warner]

I just received my new Ultimate Combination Kit for the KX3/PX3 this week.
Installed easier than I thought and it looks and works great.  I appreciate
all the time Scott invests in quality product.  It shows.  I ordered in
December but he was having problems with production and new molds.  These
covers are well worth the wait.  Now I'm anxiously waiting for the new KX3
mount he is designing.  I highly recommend all his products.

 

Regards,

 

Larry

Re: [Elecraft] K3 Transmitting CW in SSB mode

[Don Wilhelm]

Stewart,

It is not in the early manuals since it was not available then.
Look in the new manual (I am looking at D10) which you can download from 
the Elecraft website.  See page 55, the CW WGHT description.  Also see 
page 36 SPLIT and Cross-Mode Operation.


If you look in past firmware release notes, you will see it described in 
the release that included this function.


It is a good idea to review the firmware release notes when new firmware 
is announced.  If you want the function mentioned, download that 
firmware (or a later level).

The U7 also makes a great audio interface between computer and radio. If 
you don't already have a good one, you might consider hanging onto it 
for when you work RTTY, PSK, JT65, etc. It is, for example, far superior 
to a SignaLink USB and the sound cards built into most laptops, to the 
extent that the U7 provides much better decoding of weak signals. If you

Re: [Elecraft] comparing P3, LP-Pan, SDRPlay, others?

[Dave Fugleberg]

I used a Softrock and a Xonar U7 USB sound card for awhile til I got my P3.
I tried a few different SDR software packages, which each had their pros
and cons.
Now that I have a P3, my Softrock and U7 are for sale.
The Softrock I have is overkill for a panadapter - it's a RXTX Ensemble in
a KM5H case, when all that's really needed is a receive-only unit. The U7
is about 6 months old- I only bought it to see more of the band at once.
If anyone is interested, please contact me off list at w...@arrl.net.

Re: [Elecraft] KX3 2m external amplifier

[Bill Frantz]

I have a 2M amp about 80 watts from Edward R Cole, KL6UW. I 
drive it with my 5W HT. It seems to work well, although I just 
got it working a month or so ago and have been away most of the 
time since. Note that Ed will set it up for the drive level you need.


Pluses: Solidly built. Automatic T/R switching, or by control wire.

Minuses: Little/no protective circuity. Class A so it draws a 
lot of power with no input.


I built mine as a kit and it was a fun build. Since I was an 
early adopter, I asked Ed a lot of questions and got very useful 
support throughout the process.

Re: [Elecraft] KX3 2m external amplifier

[Charlie T, K3ICH]

My TE Systems 1452G amp puts out a tad under 400 watts with 4 watts drive.
AND it is biased for linear service.

I've been very happy with a vintage RF Concepts 2-417. It's rated for 170W
out with 45W drive. However, I used it very successfully driving it from my
TH-F6A 5W HT. I never measured the output with that drive, but it was
clearly considerable. Also, the preamp is quite good. These are readily
available used, best guess is price around $175-250 for one in good condx.

Re: [Elecraft] KX3 2m external amplifier

[Mel Farrer via Elecraft]

Any of the older ones rated at less than 10 watt in and a linear version not 
Class C will be fine.  I have used the KLM, Mirage and TPL units with success 
on two meters with various rigs both FM and SSB.  There are quite a few on the 
used market, just make sure it still works as advertised for rated output.  

Good luck.

Re: [Elecraft] KX3 SDR

Did not mean to imply that the Raspbery Pi or BBB panadpater was anywhere
close to the PX3, but that looking at the code could help with OP's original
question.  Built mine while waiting for PX3 and yes they are day and night
re functionality and ease of use.  I love my PX3

Re: [Elecraft] comparing P3, LP-Pan, SDRPlay, others?

[brian]

If you have SKIMMER on the subrx's IF, you also need a different RIG 
file for SKIMMER to do this.


It's really neat though.  Send SKIMMER spots to the logging program. 
Click on them there and VFO A goes to the spot.  Click on spot in 
SKIMMER and VFO B goes to the spot.

True.  However if you have a KRX3, CW Skimmer can use VFOA for TX/RX pileup
and VFOB for RX DX frequency *without any other program needed*.  Since I
already have a KRX3 (necessary for diversity), I created a simple Macro to
program VFOA for TX and VFOB for RX (see my previously referenced link for
the Macro) allowing Skimmer to jump the TX frequency to Skimmer's 599

Re: [Elecraft] KX3 2m external amplifier

[Tim Tucker]

I've used mine with the Mirage B-320-G quite a lot.  It works great, both
FM and SSB with no issues.  I've also used it with a little Tokyo Hi-Power
35 watt amp and had no issues, either.  There really isn't anything
complicated about getting the KX3 2m going with any amplifier - just make
sure the one you choose will deliver the power you're looking for with 3
watts or less input.

My neighbor W6GJB and I both have K3s with Elecraft 2m transverters. His 
is internal, mine is external (I've owned it for more than ten years). 
Several years ago, we searched for and acquired vintage (30 year old) 
brick amps that drive with either 2W or 10W for an output of about 150W. 
They have built-in preamps. These vintage amps were made during the 70s 
and 80s with the Mirage and RF Concepts name, and were built in Northern 
California. They also made versions of these amps that required higher 
drive levels -- 30W and 50W, I think, and they also made versions for 
440 MHz. I own some of those too, which I use with the FM rig in my 
shack. The Mirage name was later bought by MFJ. We found four of these 
vintage amps in good condition in a few days simply by asking on two 
local club reflectors. I don't remember what we paid, but I do know that 
we considered them a bargain. :)


Those older amps are a great fit to an Elecraft rig with an Elecraft 
transverter. We use the version that drives with 2W so that we can run 
the transverter at the lowest possible power, thus reducing heat.

Here's another neat thing you can do with Skimmer and a script to

As I said "Skimmer is the only SDR program I'm aware of that calculates
exact frequencies for its decoder dots" and I haven't researched newer
programs since 2011, so there are probably others now.  

BTW your comment assumes the calling station in question is still there for
CWT-like behavior to work.  The 599 function will send the K3 to the
frequency of the *last* station worked in the pileup, even though he's
probably no longer transmitting.  

Here's another neat thing you can do with Skimmer and a script to control it
via a mouse wheel.  I use the wheel to quickly tune up or down the band in
contests.  No need to mess with carefully positioning a mouse, pressing a
knob, etc.  Note that this is Blind Skimmer mode (no callsign decoding)
which is legal for unassisted contest categories.

Re: [Elecraft] KX3 SDR

I built that one using a Raspberry Pi a couple of 
years ago, pre-PX3. Worked fine for what it is, 
but ergonomics are not even close to that of a PX3.

Re: If you want to point and click to EXACT frequencies, I recommend CW Skimmer

Both CA Skimmer and Rocky have this feature.  All you need to do is click 
within a pixel or two of the desired signal and it pulls the frequency to zero 
beat the signal.  I have only used it on CW, so I don't know if it works for 
other modes.  It is similar to the CWT function.

If the P3 and PX3 don't have this feature, they should!  It would complement 
the "Elecraft Quality" that they build into their radios.

Re: [Elecraft] KX3 SDR

[Lyle Johnson]

Sorry, I was thinking of the KX2 which always has the IF shift enabled.

In a KX3, the center of the IQ stream is approximately the dial setting. 
I say approximately because some modes (AM, FM) or submodes (narrow SSB 
using Weaver demodulation) there may be some offset regardless of the 
setting of IF shift.


Thank you for your careful reading, Greg!

73,

Lyle KK7P


The signals at the IQ jack on the KX3 are analog, not digital. They
are centered approximately 8 kHz away from the dial frequency as the
KX3 uses an internal offset of 8 kHz.  Depending on the firmware
release and user settable options, that offset may be on either side
of the center of the IQ audio.

Do you mean always 8 kHz off, or is this only if the IF shift is
enabled?  I would expect a 0 offset without that.

> Can anything  besides the P3 be used to point and click for QSY?

If you want to point and click to EXACT frequencies, I recommend CW Skimmer
with LP-PAN.  Skimmer is the only SDR program I'm aware of that calculates
exact frequencies for its decoder dots.  When properly set up (which takes
some doing), you can dead zero beat decoder dots simply by clicking them. 
This was one of my gripes about the P3.  It's difficult to position the
cursor exactly and then press the knob without applying any torque which
will slightly shift the frequency.  

Another useful feature of Skimmer in large pileups is its "599" function. 
You can watch the display for a magenta 599 to appear and then click to the
exact frequency of the last station worked.  I've worked stations in very
large pileups without ever actually listening to the pileup itself.  I do
dial in a small XIT offset so that I'm not dead zero beat with others using
the same technique.  For determining the pattern that the DX is using to
work the pileup, it's simply a matter of watching the 599s to appear to see
whether the DX op is working up the band, down the band (and by how much) or
random tuning.

Here's a recent post about how to do this (note that a KRX3 is required)
including a link to the Skimmer page which showing the 599 function in a
very large pileup:

Re: [Elecraft] comparing P3, LP-Pan, SDRPlay, others?

[Arie Kleingeld PA3A]

NAP3 + Softrock IF + built-in stereo line in (96kHz samplerate) is best 
bang for the buck if you want to see the band, point & click and solid 
integration with K3 and other software.


The combo here is:
- software: N1MM logger + NAP3 + LP-bridge
- hardware: Softrock-IF, built-in soundcard on 5 year old laptop (can 
run at 192kHz) or back in the shack an 8 yr old vista-Dell with $50 
soundcard.


Use the point and click when scanning the band and looking for certain 
stations or QRM free frequencies.

Re: [Elecraft] P3 - Center/Top Spectrum Frequency Stays Zero?

[Charles Johnson]

Same exact issue here. The P3 screen also became slow to refresh, like once 
every 5 seconds. Turn K3 and P3 off/on solved the issue. This only happened 
after a screen capture.

Closing the “COMM PORT” and reopening did correct it.  I have had other issues

Re: [Elecraft] P3 - Center/Top Spectrum Frequency Stays Zero?

[Don Wilhelm]

Bret,

Do you have the RJ-45 plugged completely into the K3S?
Push on the cable (not the hood) until you hear a click - or pull back 
the hood and push directly on the plug, again until it clicks.

Re: [Elecraft] QSLs

[Edward R Cole]

First off, my thanks for all the suggestions from several people.

Here is how I make my QSL's:
1. The photo is opened with Paint (it is found by clicking "START" 
then clicking "ALL PROGRAMS" and a dialog window opens which I click 
accessories and click Paint.
2. I use text from Paint to add lettering on the image; be sure to 
click transparent text else the test window will produce a white 
rectangle within which the test is inserted.  Word Art is also handy.

3. Once I have the photos with added text set up I save the file.
4. Next I open MSWord and insert the photo, sizing it so four images 
fit a 11-1/2 by 8 inch page; select Landscape format for this.  You 
just insert the image four times resizing to fit after each one is open.
5. I use MSWord to produce the back side text and save it under a 
different file name.
6.Then I use a plain sheet of paper to test print the cards; you may 
need to move the images on the MSWord document in order to align well 
for using 4 segment card stock.
7. One side of the card is printed using the image file; then I open 
the text side and print the backside of the cards
8. Take note of how to insert the unprinted card stock so you print 
on the blank side and not on the side that was already printed.

9. Separate the individual cards using the perforated lines on the card stock.

Hopefully you have a little art sense for layout of your cards.
