[Elecraft] UK Elecraft net report for Sunday 2nd November
We managed without too much continental QRM this week. Topics were: Memory (band switching) use with the latest firmware. LP-100 power meters (several stations on the net are now using them) IF shift when reducing bandwidth on SSB. Suggestion that the centre frequency should be 1.35 KHz not 1.5 KHz... Notch, manual vs. auto, K3 notch vs. Perseus notch. Fitting PL259 plugs Overall audio quality. Circuit differences between the latest release of circuit diagrams and the earlier ones (PA differences in particular) K2 DSP settings. Filter offset issues/problems when using the 2nd receiver. Stations were: M0GJH, Andrew G0MJW, Mike G0VGS, Ian M1PAF, Paul G4ARI, Tim GM3SEK, Ian GM0ELP, Doug G4NWJ, Jim 73 until next week.

Re: Re[Elecraft] minder - UK Elecraft net Sundays 0900 local, 3630 KHz
Dave Thanks for running the Net every Sunday. I would like to propose a change of frequency for the net. Down here on the south coast I am clobbered badly by continental QRM. Can we try around 3.720Mhz, Normally it is much clearer of the continental traffic. Regards Rod G3YHM Dave G4AON wrote: > > The frequency as always is plus or minus the QRM.

[Elecraft] UK Elecraft net - change of frequency?
Rod (G3YHM) posted a message proposing a change to 3720 KHz to reduce continental QRM. Can I have the views of others as it makes no difference to me what the frequency is. The original frequency of 3630 KHz was chosen so that we might have been able to run wider bandwidth modes such as AM and ESSB, both of which are available with the K3 provided it is fitted with the 6 KHz IF filter. There are so many stations on 80m between 0900 and 1000 on Sunday mornings that running such wide bandwidth is not desirable. Operating, or even testing, AM and ESSB higher in the band is not a good idea at any time. Note there are daily AM nets running on 3615 and 3625 KHz. Options to consider are: 1. Stay put and operate at the same time. 2. Stay on the same area of the band and start an hour later for potentially less continental QRM. 3. Move higher in frequency at the same start time. 4. Move higher in frequency and start an hour later. Can you e-mail me off the Reflector with your preferences and I'll see how it pans out. Regular net members views will be considered before others. 73 Dave, G4AON ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2-100 Alignment & Installation problems
Page 46 of the manual where I turn on the K2, I DO NOT see NO PA PS as called for in the manual. When I tap display my voltage has dropped to 11.3 volts. Measured at the source it is still 13.5. Measuring the voltage at Junction of C77 & R11 I get 74.1 volts which is not in the range specified. At J3+ lead I get -0.004 volts. Page 47 adjusting C27 to move the 4Mhz oscillator frequency has no effect on the oscillator. When I place the K2 in Tune, the display only shows power and does not show the SWR. C1 has no effect on SWR. Page 48 after connecting high current power supply the voltage readout at Display is still 11.5 volts and voltage measured at source is 13.85. I looked at the troubleshooting instructions and found nothing that would help me with this "low voltage display" problem nor the low voltage at C77 & R11. Does anyone have any ideas???

RE: [Elecraft] So you want an analog s-meter for the K3?
The BG command does indeed truncate to S9 when CWT is selected. SM does not. I chose BG because it reports during TX. I'll be switching to SM because the BG data currently being reported during transmit is either SWR or CMP, depending on the RF/ALC selection; although the programmer's reference says it reports RF or ALC levels.. This may change.

Re: [Elecraft] Bigger K3 S-meter
Agreed A calibrated S meter could be useful tool in many other ways. - Measuring field strength and patterns of antennas. - Reporting on things like BPL and other radiated and conducted measurements that seem to be a daily threat on HF. Just knowing they close to S9 plus plus minus 20 db is not a professional way to build an argument against such pollution in professional circles. Having a calibrated S meter and adding something a like calibrated loop with a known antenna factor would make collecting and surveying potential RF pollution data very easy. While we don't need 0.1 db accuracy 1 db of accuracy is easily achieved in SDR radios. http://www.vk1od.net/bpl/QueanbeyanBplTrial2.htm - Using a good S-meter would also be a reliable way of surveying a potential new QTH. The data could be used to compare signal noise levels to the thermal noise floor, or even compare what you are measuring to the surveyed ITU noise levels on HF. It would be nice knowing that your potential new QTH is in a QRM silent location. It would also be good comparing noise floors amongst hams for various locations. - It would also be useful knowing how accurate and reliable propagation programs are on a daily basis since they do predict signal levels. This might come in handy if one wanted to build a DSP based DF system which relies on ionospheric data. - As a general level meter around the shack, it could even be used as an accurate power meter. So to me a well calibrated S-meter can take the place of many expensive instruments that most hams dont have access to on a daily basis. It is a very useful tool. When we use some sort of absolute reference our understanding of what we are measuring on a daily basis increases our understanding of what we are doing in our hobby. While we on this subject if further work is carried out on the K3's s-meter you might as well follow the IARU's recommendation for S-meters and make it quasi peak in nature. Besides these days, with the competition increasing in the new radio market with radios like the Perseus, ADAT and the newly released cheap Flexradio models, all which offer a very accurate S-meters as a feature. It would do no harm to the K3's reputation having a feature that some consider desirable, that's marketing not rocket science. 73 Craig ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Correct Link..
Not to discourage innovation, but I ran the program and as expected it did only the meter on the radio already does. I have spent too many years working with computers to think anything is neat just because it is done on the computer. Personally I will not use it, as I don't want to have to start a computer program in order to use the radio, unless the computer brings something really spectacular, such as panoramic reception, or digital modes. (While the K3 can do digital modes internally, for my personal purposes I consider it a useless gimmick, just like this software S-meter). - Original Message - From: "Julian, G4ILO" <[EMAIL PROTECTED]> To: Sent: Sunday, November 02, 2008 11:31 AM Subject: RE: [Elecraft] Correct Link..

RE: [Elecraft] K3 max power out 63W?
I was using the internal wattmeter in the K3. I don't have an external wattmeter. I hooked the radio up to an oscilloscope today and the power maxes out between the 60 and 70 watt setting. The scope is an old Tektronix 422 and the absolute measurements probably aren't that accurate, but the relative measurements should be valid. Here's what I get: Setting Output 10 9 20 16 30 23 40 31 50 46 60 67 70 77 80 77 90 77 10077 11077 12077 The measurements are subject to interpolation of a fuzzy line on a small, old crt on an old 15MHz scope, so I'm not as concerned about the actual numbers as I am the fact that they level off after about 65 watts indicated on the power setting. The measurements were take on the 160m band into a dummy load with the ATU bypassed and an indicated SWR of 1.1-1. I'm thinking that one of the finals in the KPA3 has failed.

Re: [Elecraft] K3 RF Feedback Problem
I bit the bullet and removed L4 and L7 this morning. It is not difficult; they are both on the back of the front panel board. I jumpered the pads with wire. I am now getting superb audio reports from critical local stations that were guiding me in reducing RF on my audio. My MC-60 mic is back in good graces. It works. Monty K2DLJ Even in balanced audio systems, the same rules apply. Had the K3 been designed with a truly balanced, 3-stage instrumentation input for its mic pre-amp, the inclusion of L4 and L7 on the shielded return paths would have the same effect. The saving grace in an instrumentation-input circuit (or in the alternative, an audio transformer input) is the inherently large common-mode rejection ratio (CMRR) across a very broad frequency span that limits the presence of RF on a twisted-pair audio line, even in the total absence of the cable shielding. For nearly 100 years, the Bell System and its progeny have used unshielded twisted-pair balanced audio systems in the presence of outrageously-high RF fields with no measurable detriment to performance in many instances.

Re: [Elecraft] K3 RF Feedback Problem
I bit the bullet and removed L4 and L7 this morning. It is not difficult; they are both on the back of the front panel board. L4 on the front panel board is related to the issues some folks are having when using the front panel mic connector with various audio routers. It can be shorted with a jumper from pin 8 of the mic jack to ground. L7 on the KIO3 audio I/O board can also be bypassed for the same reasons when using the rear panel mic jack in similar installations. L7 on the front panel board is for reduction of noise from the RS232 serial port lines and should definitely not be bypassed! 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Using K3 with AMP
Don Wilhelm wrote: George, What K3 jack are you connecting the amp to? You should be connecting to the KEYOUT jack. If you have connected to the K3 PTT input instead, I could understand that you might have difficulties like you describe. Or to the "KEY" input next to it, it if was in CW mode... ~Iain K4GM-George wrote: For several years I keyed my Dentron Clipperton L amp from the jack on my Pro II. I did not use any buffer and it always worked fine because the voltage/current being keyed are w/i limitations of the Pro II. Without powering up the AMP I ran a cable from the AMP to the jack on the K3 I just received. I noticed that WITHOUT AC power to the amp when I moved the standby switch to operate the K3 PTT was keyed and the rig put out normal power. This is w/o the AMP being ON. Any thoughts from anyone? I do have an AMPKEYER available to use between the units but thought I could key the AMP directly. Why would my STANDY/OPERATE switch on the amp operate as a PTT switch? Do I need to set a parameter in the K3? Of course all equipment share a common ground connection. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] SS... aka - More Fun
So.. with the temp outside in the 70s, and no wind... partly cloudy skies... it was a nice day, to spend, at the radio.. trying to get a WAS and a sweep.. well... neither one was readily available... at least with the conditions as they were. However, and here is the good part... I had my K2 set up with three antennas, and with the bands open, but long, this morning at 2 and again at 2... local time, I ran, with all 5 watts screaming out the antenna, holding the freq rather nicely, and when the crowding began... the rx stayed right with me, and only when the run faded because the crowd, was where? All over me... I found as I opened the rx back up. ON top and on both sides. So.. I figured this was a good time to go try it again.. and I did... and again and again.. on 80, and on 40 then the true test... up on 20... down in the middle of KW alley... here is the test that doesn't show on the bench... a rx that shows up good on the bench is one thing.. altogether a different animal when it comes to KW alley in the middle of SS... however... I found that actually putting the pressure on the rx was a joy to watch and lisen to. No funny stuff, and the constant pressure from the electric fence kept out by the nb, was also a joy. No ill effects at all. I knew the rx had nice specs.. proved it on the service bench. But putting it into the fray at a full press, was fun. How did it do? Well the op failed after about 18 hours... but it made over 300Qs and 72 Sections not a sweep, but popping through piles was a breeze... and that is about 85% rx... and 15% antenna when they stack up that deep. No, didn't get WAS, missed it by ND, and DE... and a sweep was left out by a handful of VEs missing. 6 maybe. anyway.. it was a blast, Now, Thank you Elecraft... to put it the best way for the moment.. That was fun, and my head doesn't hurt. --... ...--Dale - WC7S in Wy _ Stay organized with simple drag and drop from Windows Live Hotmail. http://windowslive.com/Explore/hotmail?ocid=TXT_TAGLM_WL_hotmail_102008___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
