[Elecraft] K3 S-Meter Calibration

In case anyone wants to compare, I just calibrated my K3's S-meter with an in-cal HP 8640B.The new firmware (Version 1.87/1.69) includes the magic S-meter that reads the same no matter what (pre-amp, attenuator, etc.) and since the firmware documentation said recalibration is required,

[Elecraft] FS: KX1

Well, it breaks my heart, but I've got my K3, and I've now Pelican- cased my K2 to be my new portable rig, so it is time to sell the KX1. The details: KX1 4-band (80, 40, 30, 20) Serial #702 Built by an Electrical Engineer with extensive building experience and the proper tools - me :)

[Elecraft] FS: KPA-100 Built and tested

I find myself now with a K3, a K2/100 and a KX1. I don't need them all, so here is what I would like to do. I'm going to sell the KPA-100 and use the QRP K2 as my travel radio. I will also be selling the KX1 before long, but for now, let me offer a perfectly functional KPA-100, built by me

[Elecraft] K3 Line-In for PSK31 not working

Alan - I have used PSK31, MFSK16 and RTTY using Hamscope with no problems. However, the rear panel LINE IN (mono) and LINE OUT (stereo) jacks are 3.5mm, NOT the old trusty 1/8 inch (they are slightly larger). I initially used some 1/8 plugs I had, and they worked, but were loose and

[Elecraft] DSP for KX1 and K1

The nature of the KX1 (and the K1, hope to build one of those soon) would argue for a very low power, simple DSP. Since they are CW only rigs, Autonotch doesn't make sense to me (wouldn't it attack the CW note you are trying to hear?). Also, the KX1 built in crystal variable filter works

[Elecraft] Elecraft Net Report for January 6th and 7th - Minor correction

Kevin - Just a note to congratulate you on being able to hear me on the 7045 KHz net yesterday evening. The band was way down here in TN and the QSB was rapid and deep. The minor correction is that I was on K3 serial # 175 for the net - my K2 (# 5540) was asleep and resting. As usual, 100

[Elecraft] K3 Receive 500 - 700 KHz

Yep, just did it tonight on K3 serial number 175 - works great! Listened to WSM (650 KHz, showing S9 + 40 but I'm close) and some others. Mostly you hear AM broadcast radio stations, of course. I also tuned around the 2-3 MHz areas and found the nearby shortwave station (WWRB) and the 6

[Elecraft] TXG Message

Regarding the TXG message: I just finished the assembly and alignment of K3 SN 000175. During the low power transmitter gain calibration, I got the same message. It happened to me in the 60M band. Apparently, after doing the synthesizer cal, the VFO stops on some frequencies unsuitable

[Elecraft] K3 S/N 175 Received

Sorry for the late report - I just got back in from out of town: K3/100 kit S/N 000175 Invoice 47515 Ordered May 2 with 50% deposit Received via UPS on Dec 20th. With luck, I hope to have it on the air by Sunday, Dec 30th. Merry Christmas! - Bill K4DXU

[Elecraft] Dayton experience

Just got home a few hours ago. Let me add to the comments of the others regarding the K3 and Elecraft at Dayton: 1 - The K3, in terms of looks and quality, is a world beater. The way the controls feel, including the pushbutton functions incorporated into some of the knobs, is first

[Elecraft] W1 Enclosure by W8FGU

For those of you looking for an enclosure for your W1 wattmeter, let me recommend the units made by Dave Van Wallaghen, W8FGU. I received my enclosure earlier this week, and installed my W1 into it today. Everything fits perfectly, and it really completes the W1 and converts it from a

[Elecraft] Case for W1 Wattmeter

I know several folks have asked for ideas about cases for the naked W1 wattmeter. I recently acquired a Pelican 1040 MicroCase (they are sold new on Ebay) and it works great to protect the wattmeter during transport, etc. I mounted the BNC jacks on the bottom of the board (and used elevated

[Elecraft] Re: KPA-100 Power control unstable on 40M

Steve - Much obliged. I tried the mod you addressed and that has settled it down. Just a slight overshoot when set at 100W. More when running lower (25W), but not as bad and I don't really care since the KPA-100 has plenty of headroom down there. I used the 1K and 3.3K values on the

[Elecraft] Unstable power control on 40M SSB

Folks - I just completed the KPA-100 amp for K2 #5540 and everything is great except for one problem. My memory tells me that I have seen something on this before on the reflector but I cannot remember the solution. Anyway, I am seeing unstable power control on 40M SSB. 40M CW seems

[Elecraft] Re: Suggestions for a paddle

Gentlemen - Amen to the Begali paddle! I've always been allergic to Iambic mode (it seems to want to talk when I want to shut up!) but I liked the thick feel of the iambic paddles. Begali shipped me a Simplex Mono, problem solved. It is a mechanical work of art. They gave me great

[Elecraft] Raspy Audio from K2

John - I saw your message on the ECraft reflector. I have tried exactly the same thing in my shack, and I always will hear a raspy audio sound, even from perfectly functioning rigs that get FB on air reports. I have never had time to track down exactly what is happening, but don't get

[Elecraft] Changes for KPA-100 Rev. D and the Toroid Guy

I just happened to have received a Rev. D KPA-100 a few days ago (I have not started on it yet). There are new loose schematics in the front of the Rev D manual with instructions to use them instead of the ones already bound in the Rev D manuals - the loose schematics are labeled Rev H,

[Elecraft] K2 #5540

K2 #5540 is now alive! It was purchased at Dayton, and first came to life about 2 weeks ago. It is a base K2 at the moment, but I have the KSB module on the bench now, and probably will purchase the KPA100 around Christmas. No assembly problems, everything checked out the first time.
