[Elecraft] K3 with microwave transverter - Frequency display
The K3 displays the frequency for bands above 1 GHz by missing the most significant digit. I would rather it missed the least significant one. Then 1296 would read 1296 rather than 296. This is I feel justified on the grounds that, for non-GPS locked systems, by the time one is over 1GHz the last 100Hz or so of resolution it is a bit less certain. Secondly, I seem to be having trouble with direct frequency entry on 2320. The IF is 144MHz via an XV144 but if I try to enter 2320.200 I can't. I can enter 144.300 on 2m so I think this is a problem only over 1 GHz.

[Elecraft] A vote of thanks to Don...
Hello Don, I will always be very grateful for the time and expertise you offer so freely to this group. Your volunteer effort is extraordinary. As a result of your support, I've completed a K1, a K2/100 and am now about to put together a K3. Yes, I had problems along the way, and although I come from a non-technical and non-electronic background, I had the confidence to give these projects a go only because I knew that friendly help was available from you when the inevitable disasters, all of my own making, occurred. You make a major contribution to our hobby and, I would add, to the on-line dimension of the Elecraft experience. It doesn't escape my attention that you do this as a volunteer. I'd like to say thank you.

[Elecraft] New Utility Problem
After downloading the new utility program, I notice when using the terminal function, I am getting garbage characters rather than the decoded RTTY or PSK31. These seem to be TB000 and similar numbers and letters. I am using the utility with my K3 #3720 with the P3 and most recent firmware. I din't have these characters until I downloaded the new utility and firmware.

Re: [Elecraft] K3 RTTY - PSK D
Rich, Yes, I have RTTY working in AFSK mode. I am trying to make it as LEAN as possible. If MMTTY can bring the FSK as a digital signal which can be fed into the K3 as digital signal (0/1) that would be nice and Lean. Just as N1MM and CW over one cable for the K3. Of course I can use two cables, one for N1MM rig control and one for MMTTY and feed that to the ACC connector using an optocoupler or so. Again, not as lean as the nice CW solution. 73 Arie PA3A Op 23-1-2011 0:37, Richard Ferch schreef: The MMTTY/EXTFSK combination can use DTR on a serial port for FSK keying, but I have no idea whether EXTFSK would work through LP-Bridge. Without EXTFSK, MMTTY uses TxD for FSK keying, not DTR, and that cannot be shared with radio control. If you are already using MMTTY, by any chance does that mean that you have an audio cable from the K3's LINE OUT to your computer's sound card? If so, a second audio cable from the sound card's output to the K3's LINE IN is all you need to do AFSK RTTY. The K3's AFSK RTTY is just as good as its FSK RTTY, so there is no reason to insist on FSK. 73, Rich VE3KI PA3A wrote: __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] KRC2 Question
I'm thinking of ordering a KCR2 Band Decoder from Aptos. I'm trying to figure out how it could be configured to control antenna selection based on mode of operation. My station has Yagi beams for UHF/VHF weak signal work, and also verticals for FM and repeater use. I know I can get the KCR2 set up to select the appropriate relay readout for a given band, but I can't see a way to automate the process of selecting between the two available antenna on (for example) 2 meters. Obviously I can do this with a manual switch setup. Any way to automate it so that I won't forget to change antennas when I switch from SSB to FM?

Re: [Elecraft] KRC2 Question
Lew, You are correct, the KRC2 cannot do that directly, but it does have the AC outputs that can be put to use such that with a bit of external diode logic it can be semi-automatic. I say semi-automatic because the selection of the AC outputs depend on tapping or holding the 4 buttons on the KRC2. Secondly, the KRC2 does not decode 2 meters, so you would have to improvise something. It could be made to work after some fashion by using the band data outputs of the K3 and substituting the decode for 2 meters with some other band. I believe that a less expensive band decoder and a manual switch is the KISS solution. The K3 has no output that indicates the mode, so a SMART solution involving a dedicated processor that polls the K3 for the relevant data on the RS-232 bus would be the only automated solution that I can think of. 73, Don W3FPR On 1/23/2011 9:22 AM, Lew Phelps K6LMP wrote: I'm thinking of ordering a KCR2 Band Decoder from Aptos.

[Elecraft] [k3] Audio distortion on strong CW signals - after a while
This is something I have noticed in contests recently, and just now in a qso with a strong local - after a few minutes, the audio becomes distorted, what we used to call a T7 note. I have read about distortion caused by banging up against the audio limiter, but this happens even at very low audio output. I also have the impression that it does not occur when I first turn on the radio, and that when I'm transmitting a lot, in contests, it starts to happen earlier and earlier, sometimes emerging at the end of a brief contest QSO. Amp or no, makes no difference, and it appears to happen on all bands.

Re: [Elecraft] KPA3 Fails Calibration
Good suggestion Greg! Tried in manually, same issue. Think it is a power supply problem, RF may be getting into my power supply, shutting it off.

Re: [Elecraft] KPA3 Fails Calibration
I think the K3 Utility's messages are a consequence of the K3 shutting off unexpectedly. When the tune button is pressed (simulated by a serial port command), it's followed with a TQ; command, which is sent to verify that the transmitter is on. The K3 has turned off, so it can't respond to TQ; That's the StartTune: Unexpected response message. If any error is detected during calibration, the K3 Utility attempts to restore the K3 to the state it was in before calibration started. The K3 Utility sent a command to start the transmitter, so it tries hard to shut off the transmitter. It loops about 10 times on an RX; / TQ; query to verify that the transmitter shut off. No response was received to the TQ; command in any of 10 attempts. That's the StopTune: Unexpected response to TQ; message. Finally the K3 Utility attempts to restore everything it changed in preparation for calibration. It attempted to restore the KAT3 to its original setting (BYPASS is used for calibration) and to restore the 50 MHz power setting, which had been changed to 50 watts for calibration.

Re: [Elecraft] K2 / KPA100 - net shorted on KPA100 -- C31 / D13 ... failure modes ?
Yep, that was it. You can add this to the list of do's and particularly the DON'Ts of the KPA-100 assembly: * When soldering Q1 and Q2, be careful not to nick the nearby components with the solder iron(s). * If the checkout step of resistance measuring D13 cathode fails and you read something like a short to ground on this net, this could be caused by C31 shorting out as a consequence of the solder process failure above. C31 had shorted out - I guess the two foils were shorted when I hit them with my auxillary solder iron. Replacement done with 2x100 nF / 63V polyester caps in parallel, and we're back again in the alignment buisness. 73' Brian OZ2BRN K2 / KPA100 # 6936 PS: and Don; Reason for asking was to check any other issues the group would have suggested at the same time, now that I had to take off the whole heat sink anyway, in order not to take it off too many times and risk damaging the heat transfer pads in the process. Den 22-01-2011 21:40, Don Wilhelm skrev: Brian, Why speculate, just remove C31 (it needs to be replaced anyway) and remeasure to confirm that C31 is indeed the problem - it quite likely is. 73, Don W3FPR On 1/22/2011 3:11 PM, OZ2BRN Brian Lodahl wrote: Hi there, After 100 % flawless work with the whole K2 journey, the KPA100 and all the add-on modules with bell's and whistles, it seems my turn has come now to have a build error on # 6936, or more specificly; the KPA-100: When doing the 2nd alignment step of KPA100, I measure all the resistances OK but one; The cathode of D13 seems very low resistance to ground and not10 kohms as expected.

The intial checkout in 1st alignment step round confirmed all diodes pass and having the expected forward and reverse voltages / resistances as expected, so I assume for now the Diodes are OK still.

Re: [Elecraft] Fw: K3/K144XV/P3 Signal Strength Readings
I realize that IARU Region 1 recommendations officially apply only to Region 1 (Europe, Africa, Middle East, N. Asia) but since I don't know of any other official recommendation that's the one I used for the P3. I was not privy to the IARU committee's deliberations, so I don't know why they recommended S9 = -73 dBm on HF and S9 = -93 dBm on VHF and above, but I can speculate. One reason may be the fact that antenna noise levels (and signal levels for that matter) are generally much lover above 144 MHz than below 30 MHz so it makes sense to adjust the S-unit scale downward. Another reason may be that most VHF/UHF transverters have gain and 20 dB is probably a representative value. So the S meter on the HF transceiver typically will read about 20 dB higher when the transverter is being used. My understanding is that is exactly how the K3 works now. However, since the gain of the K144XV is actually around 25 dB, that results in S9 = -98 dBm rather than -93 dBm. I believe it is on Wayne's list to correct that in K3 firmware.

I *was* beginning to feel a little isolated by lack of comment from anyone hihi! Although I did receive one reply offlist reporting experience similiar to mine. The Brand-E community is rather USA-centric, in case you have not noticed ;^). You bring up something that falls in the something-is-other-than-fantastic category that is not conducive to cheerleading or provides an opportunity to express economic patriotism, hence you were ignored. Hence your posts, my post nothing else but somebody saying Yeah, I noticed the same thing to you directly. Is a bit of a shame, because it gets in the way of sorting out a product that has things that need sorting out. I was not aware of the 1990 Torremolinos recommendation as such but a recent thread here on the reflector http://mailman.qth.net/pipermail/elecraft/2011-January/143651.html noted the ambiguity about 6m and Alan Bloom of Elecraft concluded that it was generally accepted that it should be treated as in the -93dbm category like 2m. However, you are correct to point out that it is a Region 1 (ie EU) recommendation and I have not been able find out whether or not there are similar or different recommendations for Regions 2 and 3. Compared with my FT847 (another rig that straddles the -73/-93dbm boundary) the S meter on the K144XV/K3 reads low on 2m and there have been a number of postings on the reflector from at least two of the IARU regions, if not all three, by people who feel that at present it reads low compared with what they are used to on other rigs. This suggests to me that other commercial rigs for 2m do use the -93dbm standard - as the P3 now does. Unfortunately I do not have any test gear that will produce a known 50 microvolts or 5 microvolts on 2m to do some checking. I accept that this doesn't seem to accord with your findings on your rig, Brett, if I properly understand them. As general comment, though, the rig doesn't seem to show enough difference in db between S1 and S9 on the bands you mention. It was the FT-847 that I was describing - one product from one manufacturer with Brand-Y's rather peculiar approach to RD is obviously not the best way to judge overall state-of-play of the industry, but it is a start I believe a more thorough look at how products are set up how they actually perform will find not many following this Recommendation (do the likes of the really good, long established respected transverter manufacturers really add 20 dB gain to the output of their products in order to comply?). S-meters are of course S-meters, we both I suspect are long enough in the tooth to understand their limitations, but a 20 dB delta is not insignificant I really do wonder about this Recommendation that is so old, may not be followed we cannot now see for ourselves why it is we were told things should be this way. It merits looking at further, especially if as I suspect (though my experience is only from IARU R3 what they get up to in their conferences), there was zero involvement of anyone other than national societies in drafting it. To anyone with a relevant professional background, this point alone is a bit of a show-stopper. 73, ex-VR2BG/p. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home:

Amen to that!

Hello Don, I will always be very grateful for the time and expertise you offer so freely to this group. Your volunteer effort is extraordinary. As a result of your support, I've completed a K1, a K2/100 and am now about to put together a K3. Yes, I had problems along the way, and although I come from a non-technical and non-electronic background, I had the confidence to give these projects a go only because I knew that friendly help was available from you when the inevitable disasters, all of my own making, occurred. You make a major contribution to our hobby and, I would add, to the on-line dimension of the Elecraft experience. It doesn't escape my attention that you do this as a volunteer. I'd like to say thank you.

Re: [Elecraft] k3 Utility 1.4.1.8 download problem
Barry: I triggered the latest version. Read below. You don't have to go to the ftp site now. This turned out to be a K3 Utility bug, which showed up in Tx Gain calibration if your K3 has the K3 CONFIG menu: “AUTO INF” set to something other than NOR. Users of a SteppIR controller might normally have this set. Earlier versions of the K3 Utility turned off Auto-Info and restored it after Tx Gain calibration was complete. A few months ago I made changes to remove Auto Info setters in an effort to be compatible with LP-Bridge’s requirements. Larry, N8LP, indicated that changing Auto Info interfered with rig sharing and that was a reason (perhaps not the only reason) that the K3 Utility wasn’t able to run under LP-Bridge. When Auto Info is on, a fair number of unsolicited responses are generated when the band is changed. The calibration code issues a band change setter, then reads the existing frequency on the new band (so that the “last used” frequency on each band can be restored), then changes to the calibration frequency. The frequency setter is issued during the flurry of unsolicited responses and apparently was lost (on some radios but not others), and the retry code reissued a confirming frequency query rather than reissuing the frequency setter. I’ve changed the K3 Utility Tx Gain calibration routine to re-issue the frequency setter in these circumstances. I’ve asked our web site owner to move the newly fixed version to the Elecraft K3 software web page. That sometimes takes a little while depending on workload. If you are suffering from this issue and don’t mind being a bit of a pioneer, the new K3 Utility version is available from this FTP site: ftp://ftp.elecraft.com/tmp/K3/K3UTIL/K3_Utility_Setup_1_4_1_8.exe Thanks to John, N1JM, for testing the new version and for supplying before and after fix traces. Thanks to Jack, W6FB, for an earlier note that suggested that my retry code should reissue the setter rather than the getter. You were right, Jack! Thanks to Adrian, VK4TUX, for noting that I had an extra period in the hyperlink to the FTP location in an earlier message. Neither of my K3s did this in my repeated tests of Tx Gain calibration with Auto Info on. Band change time is variable. 73 de Dick, K6KR From: elecraft...@yahoogroups.com [mailto:elecraft...@yahoogroups.com] On Behalf Of John Merrill Sent: Saturday, January 08, 2011 10:52 AM To: Elecraft_K3 Subject: [Elecraft_K3] Power gain calibration Must be doing something wrong.

Re: [Elecraft] Blue Tooth
I received a Bluetooth headset as a gift, and found I couldn't use it with my radio because of the delay. It made it impossible to send CW. There are audio-to-bluetooth adapters, but if you buy one for your rig you might want to make sure you can return it if there is an unacceptable delay.

Re: [Elecraft] Blue Tooth
One matter that I think should be considered is the frequency profile of one's hearing loss. A bluetooth headphone set will not normally provide for the frequency compensation that your audiologist has built into your hearing aids. Putting a headphone set over the top of hearing aids will generally result in feedback howling. An in-ear bluetooth headphone can be very comfortable, but with hearing aids removed, will not provide frequency compensation unless you add a filter circuit between the audio signal and the bluetooth transmitter. If your hearing aids are bluetooth enabled, then for a few dollars, you can buy a bluetooth transmitter that plugs into any audio output. The transmitter battery is re-charged from a USB port on a computer. Hope this helps 73 Kevin VK3DAP / ZL2DAP On 24/01/2011 6:15 PM, Dave Sergeant wrote: On 24 Jan 2011 at 12:46, Max Kempson wrote: After many decades of Ham Radio (licenced 1953) my ears are showing lack of sensitivity and signal to noise!
