[Elecraft] KAT 500 and the Yaesu FTDX10

[Greg Chartrand via Elecraft]

Thanks Joe,  I have the cbl-yne and looks like it will work OK.
I also have a kpa500 to work with the  kat500. These with the ftdx10 is a 
completely new station for me and is a majordownsize but hopefully easier to 
maintain. 
Appreciate your help.Greg

[Elecraft] FS: K3/P3 Combo

[James Bennett via Elecraft]

My new K4D has arrived! Thus, selling my trusty K3/100 and P3 combo. The K3 is 
serial number 4359 and was built by me as a kit. The P3 is serial number 878 
and was also built by me as a kit. Both have been in nearly daily operation 
since being “born”. They’ve been in a non-smoking environment since day one. 
Neither has had a bit of trouble (other than replacing a cracked VFO-B knob) 
and neither has ever been back to Elecraft for any service. Both are at current 
firmware versions. While the K3 does not have the “K3$” upgrades, it still 
works very, very well.

The K3 includes the following:

K3/100 100 W Transceiver
KAT3 Antenna Tuner
KRX3 2nd Receiver
KFL3A-400 400Hz, 8 Pole Filter (x2)
KFL3a-1.8k 1.8kHz 8 Pole filter (x2)
KFL3B-FM FM-bandwidth 8 Pole Filter
K144XV-100-K 2-m Module
K144XV REFLOCK
KXV3A RX Antenna, IF Out & Transverter Interface

All interconnecting K3>P3 cables & power cables are included.

Printed manuals Included:

K3 Kit Assembly Manual
K3 Owner’s Manual
KRX3 Subreceiver Installation & Operation Manual
KAT3 100-Watt Tuner Installation Manual
KPA3 100-Watt Amplifier Installation Manual
K144XV 2-Meter Installation & Operation Manual
K144XV Ref Lock Osc. Installation Manual
KXV3A Interface Option Installation Manual
K#\3 & KX3 Programmer’s Reference
P3 Panadapter Owner’s Manual

Spiral-bound Elecraft K3 Fred Lady (SK) manual

Price is $2,400 shipped UPS anywhere in US. If you want to pick it up at my QTH 
in Eagle, ID I can knock off $125.  I’ll accept PayPal, Zelle,  or personal 
check (must clear before shipping).

Re: [Elecraft] USB > RS232 Connection Question

[Curt Nixon]

Win 10 should discover the converter cable by itself and you then just look
in device manager to verify the com port number it gets assigned.  Set your
control software to that com port and all should then remain same.  Serial
com parameters need to match of course.

[Elecraft] USB > RS232 Connection Question

[Eric Fitzgerald]

Hello All,

It's been quite a while since I hooked up my older K3 to my computer - 
it's been running virtually flawlessly for many years. I just got a new 
laptop and before I connect it to the RS232 port via my vintage Elecraft 
USB to serial cable, I'm wondering if I have forgotten any "gotchas" 
about the sequence and/or any drivers required.  It's been so long I 
just don't remember.  Besides my shack computer is running Windows 8.1 
and this new laptop is running Windows 10.


I figured I'd ask before I just plugged it in.

The reason for this new laptop is that I am taking the old K3 (#3045) on 
the road in a few weeks to activate grid DM17 and a few SOTA summits in 
wilds of Nevada.  Here is the beginnings of the "Gridpedition" blog here:


http://kg6mzs.com/grid-expedition-to-dm17/

...and my general SOTA blog is here:

www.kg6mzs.com

For those that might want to follow along at home.

TIA & 73

Eric KG6MZS

Re: [Elecraft] K4 Data Mode Questions

[Rick NK7I]

Others with more knowledge in this area can confirm/correct this but I 
try very hard to not max any audio control, ever (except the 'power' 
control on the WSJT program, max it and ignore it forevermore).


If the setting is at max when it turns from bits to actual audio, it 
would be LOUD, which is not good because it could cause splatter, 
distortion and random artifacts from the device(s) used.  Shouting, is 
rarely effective.  Too loud also dulls the listener (the app, can't hear 
the quiet stuff over the roar).


My goal is 30-70% drive from the device (radio or computer), making up 
the difference at the other end as needed (same rule, don't crank up the 
'ears' side either, you might hear more than you want).


The "trick" is balancing the not shouting and no hearing aid required 
audio in a manner that everything plays nicely together.


In the case of the Windows CODEC for my K4; the transmit (Playback, I 
renamed to CODEC to "K4 Transmit") is set at -3.7 dB and the TX | LINE 
IN (Sound card highlighted; level at 48).   This produces an ALC reading 
of BARELY under 5, any lower dips/flickers the last bar (YMMV), a very 
slight under drive.


On receive (Record, renamed "K4 Receive") the CODEC is -5.2 dB (Main RX 
| Line Out at 20) for a reading of 40-50 on the WSJT app, with no 
received signal (yes higher than the JT manual states, just make sure 
it's never driven into the red zone with loud signals).


Each of the settings in my K4 audio, are roughly half the maximum.

In this setup, nothing is beaten hard, no distortion, flat topping, 
artifacts or other issues (others watched and listened while I 
transmitted), so it's one less concern about running a clean effective 
station.  (This works for PSK/AFSK too, no changes needed.)


Which brings up one more point, ask someone knowledgeable nearby to 
actually look at on their scope and listen to your signal; trust the 
settings you chose, but verify they're working as intended.


Then operate exuberantly!

73,
Rick NK7I

Re: [Elecraft] K4 Data Mode Questions

[James Bennett via Elecraft]

Steve - that did the trick. Just before I read your reply I came across the 
TX>Line In in the Intro guide. Sure enough, there is plenty of ALC bar now. 
I’ve got mine at 40 and it puts me one bar below the “5” mark.

Re: [Elecraft] K4 Data Mode Questions

[James Bennett via Elecraft]

Hi Dave - thanks for the reply.

Understood about #1 - I forgot that WSJT-X can force the radio to do stuff.

On #2, I use a Mac so things are a little different. The Mac has an Audio MIDI 
Setup application, and it appears to me that the USB Audio CODEC is set to 
maximum.

Anyone else have input on this subject as a Mac user?

Re: [Elecraft] K4 Data Mode Questions

[rocketnj]

I'll answer #2 first - if WSJT-X is set to Data/Pkt (which it should) in 
setup/radio then yes, the radio will switch to DATA

#1 - I am guessing you are using the USB cable to PC for sound? Check Windows 
Line USB Audio CODEC and make sure level in Windows is 100. Then on radio tap 
TX and Line IN. Make sure it is set to sound card and I have my level at 32 to

Hope this helps!

Two questions on using my new K4D for data mode, specifically, FT8.

First, with both VFOs set to DATA mode, no matter what I do I am only able to 
get two bars on the ALC meter. I read in the operator’s guide that I should 
keep it under the “5” mark. On my K3, I always kept four solid bars and the 5th 
flickering. Obviously two bars is wy under that “5” mark, but why, when I 
advance the MIC level from 1 all the way to max, does the ALC meter only stay 
at two bars? I am able to make contacts on FT8 so the thing is working, but I’m 
puzzled. Should I be able to get more than two bars of ALC in DATA mode?

Second - the K4 seems to think for itself. After scratching my head regarding 
that ALC level issue, I decided to try using USB mode. I put both VFOs into USB 
and…… this sneaky radio automatically switched both of ‘em back to DATA mode as 
soon as I transmitted. Is that normal / expected?

[Elecraft] K4 Data Mode Questions

Two questions on using my new K4D for data mode, specifically, FT8.

First, with both VFOs set to DATA mode, no matter what I do I am only able to 
get two bars on the ALC meter. I read in the operator’s guide that I should 
keep it under the “5” mark. On my K3, I always kept four solid bars and the 5th

at two bars? I am able to make contacts on FT8 so the thing is working, but I’m 
puzzled. Should I be able to get more than two bars of ALC in DATA mode?

Second - the K4 seems to think for itself. After scratching my head regarding 
that ALC level issue, I decided to try using USB mode. I put both VFOs into USB 
and…… this sneaky radio automatically switched both of ‘em back to DATA mode as 
soon as I transmitted. Is that normal / expected?

Re: [Elecraft] k3 no power out over 12 watts

[Michael Carter]

Hi Scott,

Check the KPA3 settings in the CONFIG menu
to be sure the 100 watt PA is not bypassed.

If the KPA3 is set to PA NOR in the CONFIG
menu, then you may have a diode failure
in the PIN diode T/R switch or the PA bypass
PIN diode switch.

Mike, K8CN

[Elecraft] k3 no power out over 12 watts

[NE9U - Scott Jasper]

Turned on my k3 couple days ago and I suddenly have no power out over 12 
watts.  Had been working fine prior to that.??


Tried running the power calibration routine.  5 watts calibration 
worked.  50 watts erred out.


rig is not in test mode.

any hints on anything to check?
