Thanks Don. Got it working. Now to get my Flex 3000 working (I have an early model K3 (S/N 157) and a Flex 3K (S/N 150). Interfacing the K3 is a lot simpler than integrating the Flex 3K with all the station peripherals. I've been so busy with work over the last couple of years that I do not have the time to work/play with the radio configurations as much as I would like to.

Re: [Elecraft] Elecraft Amps
As I recall Eric stating when they first were developing the KPA800/1500 kits that some portions (high voltage boards) would be pre-assembled for product liability/safety considerations. There probably are a few KPA800/1500 beta amps existing somewhere since I believe they were doing some early field testing back in 2006 or so. In 2005, Eric had a working prototype of the KPA800 in his room at the Holiday Inn (QRP hotel - kind of ironic). I believe they had a KPA800 and KPA1500 at the Hamvention in 2006. And in 2007, the K3 took centerstage. Time flies I guess. Doesn't seem like it was almost 4 years ago that the amps were shown at Dayton.

Re: [Elecraft] K3 compatible Pan adaptors
Not being facetious, but you can take the IF output from the K3 and feed it to the antenna of an IC756P3 or IC7600, etc. Just tune the Icom to the IF freq of the K3. An expensive panadapter - yes. Just make sure the Icom never transmits or the K3 will be history. I guess this has been done with K2, etc. I have an IC7600 but have never tried it yet. I also have the LP-Pan. But if I want SDR, I'll just use my Flex3000. As you can see, I am an equal opportunity ham - Yaesu, ICOM, Elecraft, and Flex, not to forget Kenwood. I still favor the K3 above the others.

[Elecraft] CW and VOX
Yesterday, suddenly my K3 had no RF output on CW. It had been a few days since I was on so I was kind of mystified since it worked fine last week. The TX light was flashing, and I could hear the TX relay in the PW-1 amp clicking. In desperation, I went to SSB mode and there was full output power when I spoke into the MIC since obviously VOX was on in SSB mode.. I did not consciously notice the VOX missing on the display in CW mode. I went back to CW, and then I noticed the VOX was not displaying. I never consciously turn off VOX but obviously I held the Band switch a bit too long and turned off VOX during a band switch last week. I never use the QSK option. So I experimented a little bit. I turned on VOX and QSK then I turned off VOX, then turned off QSK, and SEMI appeared in the VFO B display briefly for about a second. I keyed the K3 and the TX light flashed and no RF output. Am I correct in thinking that you cannot be/should not be in SEMI mode unless VOX is turned on. I am on firmware level 2.38. Without VOX or QSK turned on, you should not be able to put the rig in transmit mode by touching the key. I generally glace at the new firmware releases to see if there are any relevant fixes I'm interested in. If not, I just choose not to upgrade firmware. The funny thing was that I did remember to make sure I was not in TEST mode since that essentially does the same thing. Essentially, if VOX is off, QSK is off, and you are in CW mode, you are in TEST mode by default. Has this been fixed in a subsequent firmware release. It can be disconcerting to suddenly turn on the K3, get ready to chase a DX station, only to find you have no RF output, but everything looks normal. If in TEST mode, at least the TX symbol flashes.

This is discussed (briefly) in the K3 Utility Help, Troubleshooting section under "USB to Serial Adapter Troubleshooting". It's the last item on that page. The microHAM router acts as if it's talking to a K3 that understands just the documented K3 command structure. The microHAM router doesn't faithfully pass through data sent to or from the PC program. The firmware load process uses data streams that are not part of the K3 command structure. The K3 doesn't understand the K3 command set until its MCU firmware is loaded. You'll have to get the microHAM router out of the way so that it doesn't attempt to manipulate the data being sent to or from the K3 during firmware load. The most straightforward way to do that is to cable the PC directly to the radio with an RS-232 serial cable or a USB to Serial Adapter that doesn't change the data stream. The microHAM router has provided an "escape" string that supposedly gets the router out of the way so that programs like the K3 Utility can load through the router. It doesn't work at this point. The router seems to be confused by the sequence of commands the K3 Utility sends as it attempts to determine the K3's baud rate and firmware inventory. I'll continue to pursue this (I own a microHAM device), but at this point in time it just doesn't work.

I do not use the ATU on my K3 on 40m since I have the SteppIR BiggIR vertical, and the K3 SWR reading shows only 1 bar which tells me it is seeing 1:1 SWR which is close to the LPA100 reading of 1.04:1. The LP100 just shows the unvarnished truth sometimes about the actual antenna resonance. It is a great tool.

[Elecraft] Firmware upload to K3 using Microham MK2
It has been a while since I updated using my own laptop. Can I use the Microham MK2 interface with the "No radio mode, and router query disabled, and 38400bps settings? I just loaded the new K3 Utility so the utility software is current. The last time I updated from this laptop, the FP flash memory did not exist. I thought there was initially an issue with using the MK2 to update but that may have been resolved in the intervening timeframe.

[Elecraft] K3 not keying PW-1 amp
I finally unboxed my PW-1, after it's repair by ICOM, and plugged in the K3. I connected the KEY-OUT to the SEND2 connection on my PW-1, connected the K3 to INPUT2, set the power down to 25w, powered up the ICOM PW-1, pushed in AMP/PROTECT so it was GREEN, the K3 is in CW VOX mode, keyed the K3, and the PW-1 only reflected 25w output. The PW-1 TRANSMIT light never lit up which says I'm not keying the PW-1. I have the K3 PW-1 negative ALC mod installed, but did not connect it up to the PW-1. I ran the PW-1 with the K3 from last December, through June of this year, configured this same way with no problems, 25w of drive will output around 1100w on 40m CW. I don't need the ALC mod but it is a nice safety net if I actually connect up the ALC connection on the PW-1. Last year, I had the ICOM756ProIII connected to input 1and the ACC1 interface to the PW-1 was connected, which basically supplies power to the PW-1 antenna switch when the amp is in the off position. The PW-1 Is in the INPUT1&2 position. Does it make a difference that there is no transceiver connected to INPUT1 and ACC1. That is the only real difference. I know that there are a few (more than a few) K3 owners with PW-1 amps. I am probably doing something wrong but it sure isn't obvious to me. My firmware level is 2.38 on the K3. I guess I could try plugging into the Input 1, send 1 inputs on the PW-1 to see if that makes any difference. The PW-1 manual does not indicate that a transceiver has to be connected to the input1 connections on the PW-1.

[Elecraft] K3 can't go to USB
I normally operate CW. I recently installed the CW rise time mod, the AGC mod, the ALC mod for the PW-1, the KXV3 option. The firmware is at 2.38. I tried to go to SSB on 20m last night and it will only find LSB now. Any thoughts?? I sent a note to support but haven't heard anything yet. I thought I'd try the list. I can't recall seeing any emails regarding this particular error. Maybe I'm doing something wrong but I know that I have used the K3 on 20m SSB many times, and did nothing out of the ordinary to do so. Is this a firmware quirk??

[Elecraft] VP6DX on 20m CW
Tonight I got VP6DX with the K3 at 1w to the SteppIR BiggIR vertical on 20m CW. They have great ears. I saw where KR2Q got them with 300mW earlier on 20m.

RE: [Elecraft] Amplifier Hook Up - PW-1
K3 #157 (factory-assembled) ordered on May 2 arrived on Xmas eve. Here's my question. How do you connect an ICOM PW-1 amplifier to the K3. I know that the ALC is a yet to be resolved issue. I have an IC756ProIII already connected to the amp so the K3 will be the second exciter. Has anyone connected a PW-1 to a K3 yet? I have to run a cable from the send2 connection on the PW-1 but what does it connect to on the K3. There are no amplifier connection diagrams in the K3 manual (yet, anyway!!) Incidentally, in a side-by-side comparison, the K3 receiver wins hands-down - no contest. I really want to try the K3 with the PW-1 in the Stew Perry Challenge this weekend.
