RE: [Elecraft] Questio when using a Heil Proset
Hi Ross, Looks like you have to switch OFF the bias. Use Main Menu item MIC SEL to do that If the MH2 works OK that means Bias is ON now. For the Heil ProSet (with #4 or #5 dyn. element) you might need the HI range mic gain (you can set that in the same menu). See p.51 of the Owner's Manual (rev.D). -- Enno, PF5X K3 #1263 I have just received my K3 and have been using it on data, and it is working well, But I have a problem, when trying to use the Heil Proset it receives ok but when I try to use the PTT I get a loud audio noise over the top of my speech, it sounds like someone giving a loud raspberry. Trying the MH2 hand mic everything works perfectly, there is no noise and using the monitor, my speech sounds normal. The problem with the Proset also occurs if I try and turn on the K3 manually.

[Elecraft] Solar Panels
Harbor Freight ('Arbor Fright for our VK readers...HI!) has a 3 panel
setup which comes with a controller and 2, 12 volt compact flourescent
lamps. Claimed power is 45 watts. Usual price is $249.
Got mine at the local Harbor Freight store on sale for $199 and was
able to use a 15% off cupon to reduce the cost to about $180 after
Pennsyslvania and county confiscatory sales taxes.
The stand for the panels is a fixed angle steel device sure to rust
quickly. I made one of aluminum angle stock with variable angle.
Measured peak power output in mid-summer for my installation is 3 amps
(about 39 watts.) The panels appear to have reverse current protection
diodes.
I regard it as a good value for @ $180. Were I to do a whole house
system, I'd go with Kyrocera and spend the extra dollars.

Tim Colbert K3HX

[Elecraft] K2/KPA100 40M SSB ALC Problem?
Hi All, My K2 ser no. 4688 and KPA100 bought 11/07 work FB on cw. On 40m SSB I have noticed a fault condition with my KPA100. On power cycle or mode change, if the power control is not set to maximum, but set so the KPA100 is 'in-line' say 20w. The power output by the KPA100 will be the full power output i.e. 100w and not 20w. This is correctly indicated on the K2 power meter accompanied with voice peaks coming through the speaker. You can imagine the problems this causes if driving an amplifier. This fault condition can be cured by doing either of the following: 1) Select ALC function on the K2 meter. 2) Whilst talking into the microphone vary the power ctrl to full then back down to the required power level. In both cases the ALC suddenly wakes up and brings the power down to 20w. The worrying thing is that I described this fault condition to another similar ser no K2 owner and he tried and found the same thing happening on his. It's early days yet and we have yet to get together and really nail down the similarities, but I ask you what hardware problem could be sorted by a simple front panel key press? I hesitate before suggesting this is a firmware problem as so many owners have not noticed this before. Please could any K2 owners of a similar ser no try this simple test and post their findings?

Re: [Elecraft] [OT] Software for Learning Morse Code
Mike, Just Lean Morse Code is my favorite. The G4FON is great but requires an add-on to allow entering text on the screen. The Just Learn Morse Code program lets you enter copy as you hear it and corrects it giving your the total percentage correct and a list of all charcters with the number of each missed, listed in the order of most missed down. I still use the G4FON software for somethings! It is great for randomly generated QSOs Many years ago I wrote an article about learning code (see www.jackandginger.com) but finally got it together recently using the Just Learn Morse Code program. BTW, I passed the 10 WPM Code Proficieny test in August of this year and in September I got the 15 WPM endorsement. Last week I took the 20 WPM test and almost passed it. I expect to pass it on one of the qualifying runs in November. Since I built my KX1 last year I have been operating almost exclusively CW!

[Elecraft] K3: what voltage is needed for ALC input (p.15 of ACC)
Sorry subject of previous posting was not indicated what radio I was talking about == Scanning through the K3 manual (Rev A2) I saw that the ALC voltage to be applied on pin 15 of the ACC connector needs to be in the 0 - +5V range. This worries me a bit because many (if not virtually all) linear amps output a NEGATIVE ALC voltage for feedback to the transceiver. I currently use my FT1kMP which needs 0 ~ -4V in combination with a SPE 1K-FA solid-state amp. It is fully interfaced including the ALC and that is working very well. The SPE outputs between 0 and -11V regulated by u-processor such that the right output is generated Is the +5V maybe a typo (i.e. should it be -5V) ?? -- Enno, PF5X mail2web - Check your email from the web at http://link.mail2web.com/mail2web ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Wood bits
Forstner bits are available to 1/8th inch, but are expensive. The reason not to use them is that the cutting edge would dull in no time due to the copper clad board. A real waste of a good bit. Mike K4ELV - Original Message - From: Jeremiah McCarthy [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Friday, July 27, 2007 10:56 AM Subject: [Elecraft] Wood bits On this side of the lake these bits are known as brad-points...There is another similar type known as Forstner, but they are much more expensive and I am not sure they are available in the smaller diameters... Jerry, wa2dkg Not sure if this is what you are looking for, but, I've tried using wood drills (the ones with the point which only cut on the outside edge, good for thin sheet metal, too) to make copper lands on a plain board. I think they are also known as torpedo drills. I've seen kits made up of lots of little squares or circles of pcb material that you stick onto your main copper clad board. That's a little more messy, but works. I prefer the drill method, it also starts a hole for your component wire.

[Elecraft] Hate the word ham
I certainly agree with Jozef. There is something called tradition. We are hams, and should be proud of that title. It took much effort in days past, unlike today. When I recieved my Extra class license it meant something other than the fact of successfully memorizing some answers. We now have Extra class operators. The FCC changed ham radio in order to get more numbers. Never mind quality, let's have numbers. Never mind the traditions. By the way I do remember my Elmer from 1956.

[Elecraft] Staking Toroids on K2
All, My K2, serial no. 05625 is complete and has been on the air for three weeks today, but I'm still in the process of adding accessories. I've mostly run it on 80 and 40 m with excellent results. One question I have for the group- Has anyone found a need for protecting the vertically mounted toroid inductors from mechanical shock events during portable operations? If so, what staking material is recommended? I am concerned about degrading exposed conductors with anything I might use for an adhesive. I think the GE Silicone II adhesive I have on hand is used for preventing corona or ionization around high voltage terminals so maybe it would be a good candidate? 73 Mike Mussler AI8Z K2 serial 05625 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I recalled a msg sometime ago from someone who gave instructions on how to use a straight key. I thought I saved it, but can't find it. Could someone pse send the directions. I recall it was a simple direction. Oh yes I now have a new problem. Since I keyed the rig I can no longer bring up the menu!! What happened??

[Elecraft] KTB1
Scott, We talked yesterday about a problem I have with subject kit. When I did the smoke test(before installing it in the K1)I did get 12 volts on the Digital VOM. I then tried to remove the batteries and found one batt to be too hot to handle. Out of curiosity I remeasured the voltage and got 11 volts. When the battery in question cooled down I removed it and noted it's casing was separated near the bottom of the batt. My first thought was that I had installed the diode improperly, thus my call to you. There is no rush to get this done. If you like I could remove the switch, diode and wiring harness and send all to you to examine. 72/73, John ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I haven't used my KX1 since I completed assembly a few weeks ago. At that time all seemed well. In preparation for a trip I got the unit out to test it.

[Elecraft] K2 AGC problem on 40m
Hi all, i would lik evening I reconized a AGC problem on 40m band. My signal meter shows S8 to S9 and it sounds like RF-Gain is turned counter clockwise. If i use ATT to reduce the signal level it does not help. The signals will drop down but it still sounds like AGC is to high. I assume it is related to the big signals from broadcast band here in europe. However, further I am not sure if my ALC is working correct. I recoginized following : If I disconnect my antenna from K2 and turn AGC ON/OFF I hear a recognizable difference. I tried to adjust R1 to get the same level. In my case I got the same level if R1 is set to the minimum value. If I do so it looks like the RF- Gain pot has no effect anymore. I assume this is not the intention. I turned it back to the recommended value to get 3.8 volts now. Any ideas where I can investigate are welcome. 73 de Joerg (DL3QQ) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] potential antenna coil forms ?
Greetings, In the course of my occupation I have aquired a bunch of heavy cardboard tubes. These are all 3-1/4 external diameter and approx 1/8 to 3/16 wall thickness. Before sending them to the cardboard recycling dump I though of offering them to the antenna coil experimenters out there. Some of them have what appears to be a plastic coating and would likely be somewhat weather resistant, but even the plain ones could be spray on plastic (or brushed on epoxy or poly resin?) coated. A list how many available and the lengths follows (the plastic coated ones identified with letter P) : (2) 32-3/4 P (2) 24-1/2 (3) 18-3/4 P (4) 18-3/4 (3) 16-1/2 (6) 15 P (5) 14-1/4 (1) 12-3/4 P (3) 12-1/4 (2) 10-1/2 I'm offering these free, first come first served, but you pay the postage, or you can pick them up if you're local. I think they can be sent parcel post without any wrappingI'll just stick a mailing label on them and send them out. When it arrives just look at the postage sticker and reimburse me that amount.

Re: [Elecraft] K2 power control
Don, I checked U6. pin 7 is okay - 5 V pin 8 is strange - 5V always (receive and transmit) I could not find a bridge somewhere on my board causing the 5V on pin 8. It looks like output of my Firmware chip is defect. This means I have to replace in my K2 Firmware chip and U6 :-( Maybe you can not help, but someone else. My antenna tuner KAT100 doesn't work anymore since the same time when the problem starts in my K2. The tuner is not recognized by K2 anymore. All LED's are dark and you will not hear the typical clip of any relay. I know in the meantime the reason for my problem. I mad a mistake in AUX cable. The KAT100 got 12 V to the AUXBUS and 8V to the VRFDET. I assume the Firmware chip and the EL5146c are also killed here. I need to order spare parts from Elecraft in US to fix my problem.

If pin 8 does have the 5 volts, then the firmware is properly enabling the chip, but if the voltage is not present, the problem goes back to the KPA100 firmware chip. If pin 7 does not have 5 volts on pin 7, then that must be fixed first - check the regulator at U3. This latter possibility is not as likely since the firmware chip uses this voltage too, and if you can turn the PA on and off in the K2 menu, the firmware in the KPA100 is probably working. 73, Don W3FPR -Original Message- Don, I checked the voltages during quick keydown.

[Elecraft] KAF2 vs DSP
I only have the KAF 2 filter, and have never heard the DSP, but I am very happy with the KAF 2. If anything, position 2 boosts the cw signal, and I don't find any ringing on the cw note. I never use the KAF2 on SSB . I consider the KAF well worth the money, especially since I got it used at a good price.

[Elecraft] Antenna feedline question
I use 450 ohm ladder line to feed a 130 ft inverted vee. But, I don't bring the 450 ohm line into the shack. I stop it at the eave of my roof, where it is terminated in a 4:1 balun. From the balun to my homebrew tuner, I use a piece of RG 213, which is approx 10 ft long. In other words, the RG 213 is all that comes into the shack. The 450 ohm ladder line is about 65 feet long and the apex of the inverted vee is about 70 feet up. This setup gives 1:1 swr, for all practical purposes, on all bands except 160, and works great on 75-80, 40, 30 and 17 meters. I have monoband beams for 20, 15 and 10 meters, so can't vouch for those bands as far as effectiveness is concerned when compared to coax fed dipoles.

[Elecraft] KPA100 No PA PS??
I have had the basic K2 up and going for a while, and have been using it while I build the KPA100. Got the KPA100 built and all the inital tests were fine on RX. I came down to the shack today (school club statio) to align the TX (since I don't have a 50w dummy load at home) and I ran into a problem. I was adjusting C1 and all was fine. OK, on to the next step. I had the plastic handled screwdriver in my hand while reading the manual, and I dropped it. Right into the opened KPA100. A couple sparks went flying. It looks like it hit the ground jumper on the front of the board since there is a black spot on it. Who knows what else it hit. Here's the problem. Ever since then, I get the NO PA PS message, even without a PS connected to the K2. I can just plug in the PS to the KPA100, and it turns on. I also get audio from my antenna connected to the KPA100. There is no antenna connected to the K2. Then after the NO PA PS message goes away, the audio goes to zero (no antenna) but the rig stays on. Connecting the antenna to the K2 shows that it reverts back to the K2 antenna port. *BUT* it doesn't do this ALL the time. The other times I turn it on, it just thinks the KPA100 is gone entirely, and I don't get a NO PA PS message. It just turns on and is silent. Again, this is with EVERYTHING plugged into the KPA100. The speaker works all the time. Any ideas??? I am thinking (hoping?) it's just a chip that I can order easily. Where should I start testing?

Re: [Elecraft] K2 knob - what are the options?
I bought a knob off of e-bay that was advertised for the K2 and other rigs. It fits the shaft fine but is too shallow so it sticks out from the face of the rig. -- The FT100 knob has a plastic pin (mold sprue) in the center of the shaft hole that must be snapped off (used a small screwdriver) to let the knob seat all the way on the shaft. Check to see if your ebay knob is the same. As to what is best...strictly a matter of your preference.

Re: [Elecraft] Blimp
I can relate to porpoising in a blimp. Friends of mine were volunteer pilots of the Fujifilm blimp, and I got to fly it twice. There's a yoke control for pitch and rudder steering, and to keep it flying level, you are always moving the yoke slowly--often to full extremes--to counter the natural unstable wanderings of the nose in two axes. Even without any boost, moving the garage-door-size elevators and rudders at the 26-knot cruising speed was not difficult, but it sure isn't anything like flying an airplane. The British AKS-600 Fujifilm blimp was the largest blimp ever manufactured, and the company is out of business now. --Dave Martin, W6KOW, K2 05120 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Containers for sorting parts
I already built K2 #4758, and getting ready to start a KPA 100 kit. To sort the K2 parts, I used plastic utility boxes with divided bins, and had no problem with the K2, but wonder if I was just lucky in that no solid state stuff got damaged, to my knowledge. I did put loose transistors in the plastic boxes, but all solid state stuff which came on the safety mat was not placed in any container before installation. I used an egg carton which was expanded polystyrene? for the hardware, and heard later this stuff is prone to build up static electricity. Was it risky to put hardware in the egg carton? I'm thinking it's not safe to have it anywhere on the bench. I always use an ESD wrist strap, and an ESD safe Hakko 936 iron, by the way. So, what is the preferred safe container?? Is the semi hard plastic utility box ok? I don't have any metal containers which are suitable.. Love my K2. It still amazes me after 8 mos of great service. In the ARRL dx test, it scored many EU stations on cw while running only 2 watts, using my Telrex 20m mono bander (which is about 50 yrs old) fed with 27 yr old Belden RG 213 coax. And I seldom had to call stations more than once. Go figger! It's also the only rig I ever had which draws unsolicited compliments on the nice cw note.

[Elecraft] K2 #5339 - deaf on 10 12m
Well, it's built! KSB2 and KIO2 installed and run fine. Only one problem so far - it's deaf on 10 12m. It's probably the LP or BP filters, but I'm not entirely sure. I tried the transmitter alignment on these two bands and couldn't get any more than 0.7 watts on the power display before the Hi-Cur warning came up. I had a very close look at all the soldered connections around the K10 relay and re-did them. I also checked the continuity of L21 L22. I then repeated the TX alignment and the power display got beyond 2 watts without the Hi-Cur warning. Only problem: the power meter on my ATU didn't register anything. Signal tracing is probably the best way of getting at a solution, but I don't have access to a signal generator. I would appreciate any help. 73 Bob 2M0KDZ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K2 frequency drift
Two questions for the group: 1. My K2, serial 5120, has worked flawless since I built it last fall...except that about a week ago, friends on a 20m net I work daily said I was low about 40 Hz in frequency. (Frequency calibration checked occasionally against both my external counter and WWV had been right on.) I transmitted first maybe 2 minutes after turning the rig on. So I dialed up about 40 Hz (.04 kHz) to get on frequency. In the next 15 minutes, I had to move the indicated frequency down slowly to the exact net freq. Drift was the obviously the problem. Since then, I've turned the K2 on early and found that by net time, it was on the exact frequency on the LCD. However, just after turning it on (room temp constand at about 68F), tuning WWV on 10 MHz (equalizing the stations's audio tone on USB and LSB) shows I'm low by 40-50 Hz, drifting up to indicated freq. in 15-20 minutes. I know that resistors RA and RD on the thermister board control drift rate, and some months ago there were comments here on how to compensate, but I didn't retain the thread. Anybody care to provide that advice again or new comments? 2. I'm currently building a KPA100 internal amplifier kit, and I'm wondering if the added heat creates drift or frequency calibration problems.

[Elecraft] Buzzy K2 speaker
My K2 had a very irritating buzz (sympathetic vibration) at about 400 hz. I noticed if I pressed on the top cover, it quit. No amount of adjusting the four speaker mounting screws worked. That ruled out the speaker itself, I reckoned. So, I took the top off, turned it upside down and put pieces of Q Pad around the speaker, covering most of the vacant area. Hot dog! Buzz went away. Q Pads are +/- 3/32 inch thick fibrous pads with one sticky side, are used in cars to quieten vibrating panels and can be found at professional auto paint stores. Used 'em on my old Ford diesel and quietened it down. CAVEAT: Since the pads are kinda heavy, and are hanging from the top panel, I can't vouch for how long they will stay stuck. They did stay stuck to the bottom of my old diesel's oil pan for years and may still be there. I traded the truck. However, they work so well if they drop down, I will figure some way to hold em up. My ohmmeter says they are nonconductive. The pads come in packs of several roughly 10 sq pads. Maybe a friendly hot rod shop would sell just one, which is more than enough area. Another idea is to affix 1/8 in thick aluminum pieces with contact cement. 73 from N4YM, George ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] OT - troubleshooting NIR-12
Hello: I know this has nothing to do with Elecraft gear, but having built the 3 radios, I knew this is the place to come for experienced troubleshooters. I have an old JPS NIR-12 DSP unit, that, after applying power, decided to quit. The power lamp will not now light. This unit does not have a fuse. So I decided to get out the DVM and attempt to see what's going on. The DC power jack goes to a T-network consisting of two 0.1 uf caps with a bead inductor before going to a DPDT switch. Beyond this is a 0.1 uf cap in parallel to ground and then a series 1N4004 rectifier diode to a 1000 uf electrolytic capacitor in parallel to ground. From there it branches to a couple of voltage regulators to get different voltages. When voltage is applied, I get 13.7 volts on the cathode side of the diode, but zero on the anode side (and beyond). I initially thought that this diode was at fault and desoldered it and replaced it with another 1N4004. But, alas, this was not the culprit. I desoldered the 1000uf electrolytic, but my capacitance meter reads it correctly at 1000uf. Can somebody help shed some light - voltage ? - here ?

I could use more sidetone volumn when transmitting. My shack gets kinda noisy at times. The level is currently set for max, 255, I think. Anyone know how to boost it?? 73, N4ym, George ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] KAT100 problems...
Hello Mike, the problem sound familar to me. When i build KAT100 everything worked fine for some hours. After a while same problem like you described appeared on my KAT100. One relay click sounds a bit different and i could not match all bands anymore. I thought a relay would be not okay, but the reason was a defect in one of the small condensators connected to a relay. How i identified the component : I turned ATU to Cal mode and meassured voltages on all 6B595 pins connected to a relay. I found one voltage below power supply voltage. After replacing the condensator it was working fine again. It happends two times allready that a small condensator failed in my KAT100. 73 de Joerg (DL3QQ) -Original Message- Date: Tue, 29 Nov 2005 16:36:02 +0100 Subject: [Elecraft] KAT100 problems... From: Mike Sexsmith To: elecraft@mailman.qth.net Hello all, I have a K2 setup (#4819) with the 100 watt tuner/amplifier in separate EC2 enclosure. Things have been FB for 3-4 months, but recently while using 100 watts the tuner is unable to get below a 9.9 SWR on 80 meters, even though other bands tune fine. KAT100 Tuner also does not seem to remember tune settings anymore when returning to a previously tuned frequency. It will retune from scratch each time... I rotated through the relays and all seem to click ok, although the relay for 80 m seems to sound slightly different...When using just the base K2 separated from EC2 the KAT2 internal tuner works fine and remembers settings. Board parts placement and solderwork appears ok. Is the relay itself the most likely culprit, or should I be looking at something else first? Could someone please point me towards things to check in order of likelyhood? Thanks for any help!

[Elecraft] Jumping K2------ No longer jumping
Thanks to all who responded to my former problem, which was that my K2 would shut down and bark raucusly when power was set to 12 w, or higher; while at the same time reverting to a formerly used frequency. I switched to a higher capacity power supply, and have not been able to duplicate the problem. I trust the problem is resolved. The weaker power supply must have been shutting down momentarily upon overload, although I could not detect it through metering. So, all is well at the moment. The little rig did fine during the CQ WW test, to my great satisfaction. And now, special thanks to my good friend Roy, W4WFB, who suggested the power supply was the culprit. I have dubbed him my Elecraft Wizard. He is one of Elecraft's biggest boosters, and it was because of his love for K2s that I bought #4758 in the first place. It is amazing how much help is available on the reflector, and how quickly it comes. Thanks again, everyone. 73, George, n4ym ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Jumping K2
Hi all My K2 # 4758 has gone strange. All is well if power is set to less than about 10 watts. But lately, if power is set to 12 w or more, it shuts down and emits a loud and nasty sounding howl, which only lasts a moment. It promptly comes back on, but the frequency changes to a previously used frequency. This was not a one time happening, but can be duplicated. It seems to be so on all bands. The only options I have is the KAF-2, (which I love), and the noise blanker. Other than this problem, all is fine, and I am very pleased with my little sweetheart of a rig. I can understand its shutting down, but why is it changing frequency and barking at me?? In its earlier days when it shut down, it did so quietly and returned to the same frequency. Any ideas?? Tnx and 73, George, N4YM ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K2 sidetone is back!!
To all who responded with help on sidetone (of lack thereof) I can't believe how much help I received from you guys on the reflector as to how to get my sidetone back. And how fast help came.

Quite a few of you are using the Samlex SEC 1223. I have a European version with 240v input. There is supposed to be a pair of jumper points inside which allows you to switch to 120v input. I can't find my handbook . Can anyone confirm the two jumper point refernces and also where are they located on the board?

[Elecraft] K2 problem with tracking ALC on 40m
Hello, i finished my K2 / KPA 100 including SSB and DSP build last week. The build was done without problems and i am on air. During my tests i found one strange thing on 40 m SSB operation. Someone told me my audio is not okay. I recognized : On 40m SSB operation the output of the PA is much higher on normal modulation level, when i compare it to other bands. I turned on ALC meter to check the the level. ALC was very high. After a short moment the level was adjusted automaticlly, like described in the documentation. I am surprised, why is it adjusted when ALC meter is enabled only ? After switch back to RF meter, the output is like on the other bands. If i switch to another band and go back to 40m the problem is back again until i enable my ALC meter. Is this a known problem ? Any hints where i can investigate ? 73 de Joerg (DL3QQ) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Re: Inverse sidebands today?
Roland, Alternatively you COULD be losing your mind !! :-) Heheheh But I'll bet Tom's right.. 73, Vic GW4JUN K2 1926 I'm not sure if I'm losing my mind or what's going on. I'm hearing upper side band on 40 meters and lower side band on 20. If this is normal then I am tripping in some alternate universe. Or is something amiss with the k2? Though I can't be absolutely certain, I'd bet you set your SSB filters (at least SOME of them) up to have them centered on the WRONG SIDE of the xtal filter center point. This will cause you to receive SSB on the wrong sideband. _ Holidaying in Orlando Florida ?

[Elecraft] RE:Morse is far from dead
Thank you lee, I was cleaning out my closet 2 years ago and contacted a local ham club to donate my gear from 1972 when I was a Novice. I met with a real Elmer and when he took my gear, he told me about the new modes and changes that had happened in 30 years. He had my interest... then he set the hook. 5 wpm for all classes of license. Code was the toughest thing I learned and 13 wpm seemed like 130 back then. I am now an Extra, and probably one of those guys that was groused about a couple of days ago with dismal code on 40 meters. I passed my extra about the time I got some gear and I hope that the 20-30 wpm crowd will take the opportunity to slow down and have a QSO with one of us code challenged guys every now and again. The best practice is when you are working someone better than you. At least you are listening to what good code sounds like and can strive to emulate it. I doubt that I am alone out here, being an extra that has barely communicated in CW. But my long term goal is to be good enough to pass a 20 wpm test, just like a real Extra. Thanks for listening to my story, hope to work some of you on the bands soon. 73, Bob AD7BP Message: 3 Date: Thu, 21 Jul 2005 19:50:16 -0700 (PDT) From: Lee Buller [EMAIL PROTECTED] Subject: [Elecraft] Morse is far from dead, gone and buried beecause of people like Elecrafters To: Elecraft Reflector elecraft@mailman.qth.net Operators who enjoy the mode need to be active in the promotion of CW.
