Hi all, Plenty of notice this week :) I will be running the UK Elecraft net on 3658 +/- QRM at 09:00z tomorrow (Sunday 28th Feb). The net is always well attended and a great place to try out settings and discuss mods etc. I look forward to hearing you all then. 73 Ian -- Ian J Maude, G0VGS SysOp GB7MBC HB9DRV-9 DX Clusters Member RSGB, GQRP 9838, FISTS 14077 | K3 #455 http://www.amateurradiotraining.org __ 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
Re: [Elecraft] Programming language and tools used by Elecraft and other for PIC programming - OT
What I would find most useful is a code in a PIC that decodes K2 auxbus commands to set an output pin according to the selected band. A bit like a KRC2 but embedded. Then I could build my own transverters/amplifiers/switches. I realise auxbus is proprietary so the PIC would have to come ready programmed.

Re: [Elecraft] Programming language and tools used by Elecraft and other for PIC programming - OT
Eeh you wos lucky, we had 't toggle boot strap in't PDP 11/05 in Octal on front panel to even get Assembler! I kid you not. Digital PDP 11/05 with Teletype. On power up, I used to load a bootstrap program of about 20 instructions with switches (0 or 1) on the front panel, so it would read a machine code loader (this was a 16 bit m/c and the code was written as a series of Octal lines, 1 per instruction, on a crib card). Then you could run the machine code, via another short instruction, so it would recognise the TT. Then you could load the BASAC (yes not BASIC, but a Solatron version called BASAC) interpreter written in Assembler into the CPU. After that, you were cooking on gas, could load ASCII tapes of programs etc. When was this?

[Elecraft] Power supply voltage reading different than K3 reading
Picking nits here, everything is within spec but... I just received an Astron power supply. Out of curiosity I was looking at the voltage readout on the K3 and noticed it was at 14.7 VDC. I adjust the Astron to 13.8 VDC and looked at the K3 and noticed a difference in the voltaged, I would have suspected a lower reading NOT a higher reading. So checked my other ps. anyway... Astron SS-25 @ 13.80VDC: K3 reading 14.0 VDC Gamma HPS1-a @ 13.49VDC: K3 reading 13.7 VDC What's going on here? I tend to trust my DMM, although...

[Elecraft] [OT] - Spectrogram software for Linux
As has been mentioned several times recently, audio spectrum analysis software can be very useful for aligning the filters in a K2 and for lots of other purposes as well. Spectrogram is frequently mentioned as a good program for Windows. For those of us who run some variant of GNU Linux, the Baudline program (available as a free download at http://www.baudline.com) provides much the same functionality. I've been using it for several months now and find it fast, very powerful, and easy to use once you get the hang of the somewhat different user interface (you WILL have to read the manual.) The manual is well written and easy to understand if you have some familiarity with sampling and basic signal analysis concepts. 73 -- Joe KB8AP __ 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

Re: [Elecraft] K3 - N1MM and RTTY - DATA/DATA A OR USB mode ?????
N1MM shows PSK mode on top of the logging window when the K3 is in Data A mode but seems to transmit RTTY OK. Depends on what you have set in the Mode Control tab of the N1MM Logger configuration dialog. I generally set RTTY to RTTY for FSK and set PSK to PSK (DATA A) for PSK. If you want to use AFSK for RTTY, I would set RTTY to AFSK and use AFSK A as the data mode in the K3. The only way the data mode matters to N1MM Logger is what it records in the log. If you set N1MM to record contest mode, it won't care what the radio mode is. 73, ...

[Elecraft] KIO2 - DS cmd shortcoming
I'm writing some code to work with the KDSP2 and have run into what I believe is a shortcoming in the DS command. When moving into kdsp2 menus where two numbers can be modified (e.g., filter, nr, nt settings) a flashing decimal point indicates which of the two numbers will be edited. However, there seems to be no way from the DS command to determine if a decimal point is flashing. Have I overlooked any way of finding this out? Thanks!

[Elecraft] laptop digital interface (Mac specific query)
I own a MacBook Pro laptop -- current vintage, which means it has only one audio port. It's a 3.5mm jack that is designed to interface with the headset plug on Apple's earbuds plus throat mike headset. The plug on the Apple headset has a tip plus THREE rings, rather than the usual two for a 3.5mm stereo headset jack. The 3.5mm jack on the Mac (the Audio Port) is supported by firmware/software that seems to detect when a plug is inserted that has less than a tip plus three rings. If I insert a standard 3.5mm stereo headset plug into the Audio Port and select Use Audio Port for Sound Output in Sound Preference, sound indeed flows to the headset. If I connect the K3 Line Out jack to the Audio Port on the Mac and select Use Audio Port for Sound Input in Sound Preferences, I get good quality sound input (verified by recording a QSO overheard on 40 meters) with sound recording software on the Mac). If I insert the Apple headset into the headset jack, Sound Preferences re cognizes that it has both an external microphone and Headphones connected to the Built in Input and Built in Output (respectively), which is of course the single Audio Port jack on the MacBook Pro. I've been working to set up my Mac for digital work with my K3 using an iMic USB interface. Now, however, it has occurred to me that, since the Line In and Line Out jacks on the K3 are equipped with isolation transformers, I ought be able to modify an Apple headset to interface between the K3 and Mac. To do this, I think that all I would have to do is cut the Apple headset apart. I'd connect a 3.5mm mono plug to the wires that goes to the throat mike, and a 3.5mm stereo plug to the wires that go to the left and right earbuds. I'd insert the mono plug into the K3 Line In jack, and the stereo plug into the Line Out jack. The other end of the cable (with the Apple four-conductor configuration) would go into the Mac Audio Port. If I have it right, the Mac would think it was hooked up to a standard Apple headset, and the K3 would think it was hooked up with separate audio lines to Line IN and Line OUT Is there any reason that this wouldn't work? Even more importantly, is there any reason that I shouldn't even TRY to make it work? (That is, would I be running the risk of damaging either the K3 or the Mac by putting voltage where it ought not to be). I have confirmed that I can input sound from the K3 to the Mac with a stereo cable connecting the K3 Line Out jack to the Mac headphone jack. I can't think of a way to verify that the sound output, which is at an appropriate level to drive headphones, would properly drive Line IN on the K3. But it seems to me that, worst case, the signal just isn't strong enough.

[Elecraft] Elecraft CW Net Announcement
Good Evening, The week has been rather good. I have spent much of it at the bench working on circuits and a little software. One of these days my web site will go live. I took a good hike on the semi-dry terrain before the clouds broke and the rain returned. The nearby stream is very low; I doubt it will last more than a few weeks after the dry season returns. At least the ferns and bryophytes are happy. The cedars love having their feet wet and grow quite large near or in the stream. I found an odd sight: a cedar and a hemlock so mooshed together I am sure there was little bark between them. I know trees of similar species can share vascular systems but I truly doubt this disparate couple could. The bands were happy this week. Both fox hunts were not too tough, at least into Oregon. I moved one rig into the front room and put it on my bench. Two antennas also made the move so I can monitor the bands while I work. I got to hear some SWBC stations so I can get the news of the world without getting on the Internet. This setup is also useful to monitor how the bands are working. However, when I tried to listen to 41 meters all I got was SSB. I had forgotten the SWBC stations there had moved :) I am happy the sun is awakening nicely. It has been a long winter, now for spring.

[Elecraft] K2 - Poor Audio Reports
On 160 mtrs, SSB as I move up the band I begin to get poor audio reports at about 1.900mhz. The tuner is showing less than a 2:1 swr at that point and I retune often as I move up. The antenna is a dipole centered on 1.825mhz. Other than adding a shorter element to the dipole, any ideas what I need to do to fix the problem? Any ideas why I'm getting the poor audio reports?

Re: [Elecraft] K2 - Poor Audio Reports
Logic tells me to first hook the K2 to a dummy load and listen to yourself in another receiver. That should tell you a lot.

[Elecraft] [K3] LED brightness
Question for K3 owners: Do you find that the setting of your LED brightness has an effect on the level of high frequency audio artifacts heard? i. e. LED BRT = 8 corresponds to louder audio tones? Note that I am NOT trying to re-open an old topic, only trying to determine a correlation between two states.

[Elecraft] K3 DSP Board Testing Procedure
Does anyone have side-by-side test results from old and new DSP boards? Or, can someone suggest a good test procedure to quantify low frequency performance improvement? I have one modified and one unmodified K3 and plan to run some tests.

Re: [Elecraft] K3 DSP Board Testing Procedure
Would be interesting! Beats me why Elecraft can´t present the facts, I´m sure they have measured since I bet they know how to. / Jim SM2EKM -- Oliver Sweningsen wrote: Does anyone have side-by-side test results from old and new DSP boards?
