RE: [Elecraft] Update SSB roundup and/or test
Even the second receiver has a big influence on how your signal sounds. At present I am building my version of a wideband monitor receiver designed by Ian G4COL, and featured in the RSGB Rad Com of November 1990. As this has no pass band filtering to colour the received signal, combined with an MP3 recording process it should provide the most accurate assessment. 73 Stewart G3RXQ On Fri, 25 Feb 2005 20:06:17 -0500, W3FPR - Don Wilhelm wrote: This sounds like a purely subjective form of 'testing' to me. There are too many variables to make a good judgement of one's audio quality. -- The position of the transmit passband with respect to the audio frequencies being transmitted is a large factor (FL1 BFO adjustment). -- The width of the transmitted passband is a secondary factor. -- The perception of the listener for 'what sounds right' may differ from your interpretation. The best way to test your transmit audio is to listen to it on a second reciever (with the K2 operating into a dummy load and the other receiver having adequate attenuation so it is not overloaded). Record your transmitted signal and play it back to hear just how you sound - you may even have another person who knows how your voice sounds normally listen since we seldom really know what we ourselves sound like. Using these same techniques, you can properly evaluate changes that you make. You can get good intelligible audio at most any bandpass width if the demodulated audio contains the audio frequencies required for best intelligibility of your own voice - each voice is a bit different in that respect. If you want information on the critical audio frequencies for intelligibility and fidelity, check out some of the articles that Bob Heil has published - there was one good one in QEX a while back (Google may show you some of them). I have no direct relationship with Bob Heil, I just feel he knows his products and audio technology quite well as it applies to Amateur Radio. 73, Don W3FPR -Original Message- My main interest was the SSB audio differences between lets say the first SSB K2's , my self modified 3155, and 4000+ models. I have a 1.07 rev SSB chip. Some early #3000's may have earlier chips. I have not asked for any audio checks from any of the 100+ QSO's. Nobody I worked had a K2. I reasoned if I did not get any complaints using 4:1 compression with the older 2.2 khz wide filter, I had good audio. I would like to see how my audio sounds to a fellow K-2 and also try a 50W amp for 20M only I built. I will be on 14.155-178 on Saturday after 2 PM EST. I also wanted to see if the SSB filter mod is for me or not. I found on RX it really works very well on 1.8Khz for RX this is good. I find not having PBT not such a loss with good 1.8KHZ filtering. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: FW: [Elecraft] Looking for local K2 ops
Oops, I said KDSP2, when I meant to say KPSK2, my name for that tight little board over TP2. I Got a nasty RF burn on my lip in 1981 from a HW-101, D-104, Unbalanced short low crappy ungrounded antenna, and haven't had much use for sideband ever since. But I did struggle with my KSB2 recently (Somehow, over the years, FL1 set itself back to 2.2 instead of op1) and I did want to dust off the [luckily plastic housed] MH2 if someone needed me. I got some pretty pictures out of Spectrogram, but since the rig was transmitting on a filter I wasn't looking at, it sounded pretty horrible. Don't even know how to tell how poorly.

[Elecraft] Mostly OT: TS-820
Hello group, I'm not sure where else to ask this question. I can't seem to get anything but an answering machine at the Kenwood Amateur Radio Tech support Center. While waiting for a new K2, I would like to get on the air (after a considerable absence) with an old (but very good) TS-820S. The problem is - too much interference with the computer and TV at rated output. Since the neighbors are pretty close, I probably would interfere there as well. I have done short tests at qrp levels with no interference. However: Is it advisable to reduce the drive to qrp levels (for longer than short tests) without damage to the 6146 finals?

[Elecraft] K2 : troubles with level on AF speaker
I'm Cyrille DERORY, a french who is living near the city of Brest. This is my first K2 (serial 4542) with optionals : SSB, 160m, KIO. The AF sound is ok with headphones connected on the front panel. However without headphones, the audio signal is very low AF power on the internel speaker or on the jack for the external speaker. After verifications, all components for the audio part are in the right position : on the control board : R16 .R20, C23 .C30, Q6 and Q7 on the RF board : R35, R36, C105, C106 I've even tried to change the speaker but the AF signal is still very low power. AF gain R3 is working. Any idea ? Thanks in advance. Cyrille. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] K2 : troubles with level on AF speaker
Cyrille: My best guess is that you have reversed the wires in SPK-J1 - The connector on the cover. OR you have reversed the ground (earth) on SPK-J2 - The speaker jack on the rear of the cover. Remove the cover and set it away from the base, Disconnect the internal battery if you have it, just to make sure there is no ground (earth) return. If volume is increased then the ground connection is reversed somewhere. Rich, KE0X ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] VCO Alignment Troubles
Hello all (again). I'm attempting to align the VCO and am having trouble making it lock on all bands or get to the right voltage range. I've verified all components on the board and touched up the solder on the pertinent components and relays (and verified all paths/continuity), but nothing changed. Here are the voltage values I get when attempting to set L30: Low High 80M 1.937V 6.000V 40M 8.000V 8.000V 30M 0.597V 0.710V 20M 0.589V 1.148V 17M 3.054V 3.250V 15M 1.962V 2.944V 12M 1.131V 1.251V 10M 2.336V 4.060V No setting of L30 will cause 40M to lock. I also hooked up the frequency counter to TP3 per a suggestion previously on the list and it measured 8.something MHz on 40 (which doesn't seem to be right. I adjusted the spacing on the turns of T5, either pushing them apart or moving them closer. I was able to bring the lower 20M voltage up to 1.5V, but then the VFO wouldn't lock on 80. Thanks in advance for any help you can provide.

RE: [Elecraft] Mostly OT: TS-820
Tom, I don't know about the TS-820S, but if the finals are run in linear mode for both CW and SSB, you can safely reduce the drive without hurting anything. If your TS-820 has a drive control, I would think it would be safe to use it to reduce the drive. OTOH, (just as a cautionary note) a few manufacturers used to run the finals in class AB for SSB, but changed the bias to class C self-bias techniques for CW (mainly to obtain greater output power in CW - but this was usually only true for ancient boat anchors). Some class C stages use the drive power itself to develop the grid bias (using rectification using the grid to cathode junction) - these designs will have runaway plate current if the drive is removed or substantially reduced. If you have fixed bias on the grids for both modes, it is very likely safe to reduce the drive level. 73, Don W3FPR -Original Message- Hello group, I'm not sure where else to ask this question.

RE: [Elecraft] VCO Alignment Troubles
Tim, Check and re-check the capacitor values. From the bands that seem to me to have strange voltage readings, C73 (should be 47pf) and C74 (should be 20 pf) are the most likely culprits. Other things to check: be certain the menu parameter for D19 is OFF - check the relays K13, K14 and K15, set the K2 for the band to be checked and compare the set/reset condition of each relay by checking continuity from pin to pin. The chart on the manual page just before the schematics shows which relays are set for each band and the schematic shows all relays in the reset position. The relay pin numbering is similar to that of an IC - you can locate pin 1 by finding the round solder pad on the board. 73, Don W3FPR -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Tim Cailloux Sent: Saturday, February 26, 2005 11:20 AM To: Elecraft E-mail List Subject: [Elecraft] VCO Alignment Troubles Hello all (again).

RE: [Elecraft] K2 first light, no first light !
Ken, Since you can see the display - and it seems to be proper, many of the front panel signals must be correct. I would look closely at the SR CK signal on the control board and on the front panel board since this signal is common to the circuits that you report as failing. Check the connectors on the all 3 boards and U6 pin 35 on the control board. This may or not be the problem signal, but is a good starting point. Re-check the soldering carefully (don't forget about the connector pins)and be certain all the pins of Control Board U6 are properly in the socket (not bent under or sticking out). Good luck and bst 73, Don W3FPR -Original Message- Am working on putting my secound K2 together, have run into a bit of a problem, am on the first light alignment and test, part 1, K2 powers up, info 201 comes on (and disapears) then the elecraft and 7100.cc c, everything seems fine to that point, but, not a single button will work, the VFO knob will not change the display, nothin, up till this point, every check, every resistance check was spot on, have checked all boards for any unsoldered joints,bridges,parts placement etc, (using a lighted magnifing glass,eyes are getting old !)anybody have any ideals as to where to start to check ?? 73 de K7ZUM Ken in GresHAM Ore Help: http://mailman.qth.net/subscribers.htm Elecraft web page: http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] VCO Alignment Troubles
Check and re-check the capacitor values. From the bands that seem to me to have strange voltage readings, C73 (should be 47pf) and C74 (should be 20 pf) are the most likely culprits. Not the caps (after a quick trip to Radio Shack to pick up a new 20pf and 47pf). Other things to check: be certain the menu parameter for D19 is OFF - check the relays K13, K14 and K15, set the K2 for the band to be checked and compare the set/reset condition of each relay by checking continuity from pin to pin. Would the voltages I got make sense if I had a K14 that wasn't latching? I checked it out and it appears to be staying in the reset position. It seems that the bands I'm having voltage issues on are all connected through K14 (40, 30, 20, 12) . (The first time I checked the relays, I did the check when 80M was the last band I used. This time I checked with 40 being the band.) D19 was off. I didn't even know about the second menu until I had to look up to verify the setting! I really hope it isn't K14. I'm not looking forward to having to replace a relay. tim ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] KDSP2 parts missing
I received my KDSP2 a couple of days ago. Just got around to checking out the parts bags this afternoon. I haven't done an inventory yet, but I did do a check to make sure all the big pieces were there and I cannot find the E100179 circuit board anywhere. It's not like there are very many places to look. Hi Hi. It's a rather small parts count and I do have the KK7P DSP module. The parts list says I am supposed to have one. I just wanted to query the group because I have cried foul twice now and wound up with egg on my face. Am I missing something I ordered the KDSP2 and the K60XV together and they both came in one box. The circuit board for the K60XV is in it's bag. In the KDSP2 bag I got a lot of small parts, but I do not see a circuit board. I have even looked in between all the pages of the assembly manual and have not discovered it yet. Any hints?

[Elecraft] K2 PLL Temp Comp mod kit parts question
I recently purchased the K2 PLL Temp Comp mod kit, and it came with Rev D (3 Feb 04) instructions. A couple places in the instructions mention replacing L31 (originally 10uH, which my rig has) with a 12 uH inductor. Yet the parts list states it should be a 10 uH, and I was shipped a 10 uH. Which is right? Considering the instruction sheet is over a year old, I would have thought any typos would have been caught by now. -- 73, Mike Boice, KW1ND Karns, TN Behold the power of the penguin Reclaim Your Inbox! http://www.mozilla.org/products/thunderbird/ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K2 PLL Temp Comp mod kit parts question
Mike, Yes, ignore that inductor change. The inductor necessary depends a lot on the crystal that shipped with your kit, and the proper value has changed from 10 uH to 12 uH and back a few times over the life of the K2. Put in the 10 uH (or re-use the one that is currently installed) and wait until you do the PLL range test before becoming concerned. Also relevant - check th eElecraft Builder's Resource Page on the Elecraft website and you will see a new note stating that a PLL range of 8.8 to 18 kHz is an acceptable range. 73, Don W3FPR -Original Message- I recently purchased the K2 PLL Temp Comp mod kit, and it came with Rev D (3 Feb 04) instructions.

[Elecraft] Blank display on 1st power up
I just did the 1st aliment smoke test. Put power to it for the first time. When I turn it on, after a second, something clicks. The display is lit but nothing else. No letters or anything. Now what? I wonder if it's one of those main chips. I got this kit partially assembled in a box. Thanks for any help. Roland in Stockton, Ca.

RE: [Elecraft] Blank display on 1st power up
Roland, That sounds like the behavior one would see if the control board is not properly plugged in. Since you received the kit partially built, you should first gain confidence in what the previous builder has done. I suggest that you go through the steps in the manual (starting at the beginning) and recheck everything - component values, proper orientation of components, and the soldering of each component. I know it is a large task, but is the only way I know to check things. Chances are very good that the components are not at fault - the most common cause of problems is improperly soldered connections, second is incorrect components (or incorrectly located components). Actual component failures are way down on the 'trouble' list - they may fail, but that is rare. 73, Don W3FPR -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Roland Elvie Whitsitt Sent: Saturday, February 26, 2005 10:12 PM To: Elecraft@mailman.qth.net Subject: [Elecraft] Blank display on 1st power up I just did the 1st aliment smoke test.

I and number of other builders missed this for some reason. Difficult to do afterwards as it needs the LCD display removing to really get at it.

[Elecraft] The audio filter
The two blue pots on the audio filter seem to offer a great range of audio filtering. However with the pots and software, I cannot get on effect I want. It might be impossible to do even if I mod it. I simply want to lower the noise floor. The noise floor is low. However I wanted to try to get it to sound like a TR-7's noise floor. Perhaps I should consider the DSP kit/up grade? My chip on my audio filter is a rev one. Is there a firmware update? Or is this chip limited to how much it can do with the multiple op-amp chip? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Mostly OT: TS-820
Hello Tom, Having spent countless hours in the company of members of the 6146 family, from their conception, please be assured that even with zero RF signal drive a 6146B will be undamaged provided that 1) Supply voltages are within specified limits 2) Real DC bias is used for the control grid (Grid 1) 3) Dissipation limits are not exceeded - in major part controlled by Grid 1 bias and 4) The circuit is stable and also free of parasitics. Grid 1 should be RF loaded, as it will be in the transmitter. In other words the same rules that apply to most tubes. I do not know the Final's circuitry of the TS-820S, but I would guess that it is two 6146s in parallel biased somewhere between AB1 and AB2. So the caution about parasitics is relevant, but if that was a problem, it should have shown up before when adjusting the output tank. I also assume that there is a real DC bias supply. So have some fun! Good hunting! 73, Geoff.

I can't seem to get anything but an answering machine at the Kenwood Amateur Radio Tech support Center. While waiting for a new K2, I would like to get on the air (after a considerable absence) with an old (but very good) TS-820S. The problem is - too much interference with the computer and TV at rated output. Since the neighbors are pretty close, I probably would interfere there as well. I have done short tests at qrp levels with no interference. However: Is it advisable to reduce the drive to qrp levels (for longer than short tests) without damage to the 6146 finals?

[Elecraft] Elecraft CW Net Announcement
Good Evening, Once again I had a very late night in the big city. The campiest production of a Shakespeare play I've seen since the scene in The Magic Christian. Last night I made a good contact into South Dakota on 40 meters and the Fox hunt went well on Thursday evening so that band may be good tomorrow evening. New Hampshire was a little tough but Missouri was easy. The first took many many calls but the latter took just one. Hopefully 20 meters will be a bit stronger than it was for me on Thursday and Friday. But we shall see what tomorrow brings us. Please join us : Monday z (Sunday 4pm PST) 14050 kHz Monday 0300z (Sunday 7pm PST) 7045 kHz Visit our web site: http://ecn.visionseer.com/ for net details. Thanks Dan. I hope 160 meters is being kind to all you folks trying for a few contacts this weekend. If you are from South Dakota or Delaware please stop by and visit for a moment. Those are the last two states we need for Elecraft WAS. No special requirements or exchanges necessary on ECN just check in and enjoy hearing folks around the continent report on their weather and their week. Take care, Kevin.
