Re: [Elecraft] K3 err msgs on powr up?

[Elecraft] Macro
This is a K-3 macro that I find useful for general DXing. To start, assume you are calling a DX station that has several other callers.You may have used your RIT or XIT or both, in order to get his attention on the best frequency.Suddenly he announces that he's listening up. You need to split, and fast, in order to be one of the first callers.You also must turn off the RIT/XIT, bring both receivers to the same frequency, and start tuning the pileup with the sub receiver. The other situation is that you arrive on frequency when the DX station is already listening to a pileup higher in frequency.The drill is similar. In both these situations you must remember to turn off the split afterward. By pushing one button, such as PF1, you initiate a macro that does the following: 1. Clears the RIT and/or XIT 2. Turns off RIT and XIT in case they were on 3. AB (all) so both main and sub receiver are identical (if filters are identical) 4. Turn on the sub receiver 5. Move the main receiver up 2 Khz. Here is the string: RC;RT0;XT0;SWT13;SWT13;SB1;UP5; L mix R is set to A Ab.Now you use the _main_ receiver to tune the pileup and transmit to the DX station.You did not use the SPLIT button. By avoiding its use you reduce the chance for transmitting on the wrong frequency later if you forget to turn it off.You transmit where you are listening in the pileup with the main vfo. To return to normal, simply toggle the sub receiver off with a single keystroke. 73, Jim W6YA __ 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] External PAN with PMSDR question on filters
Actually, there is more to it than just the 5-pole filter offset. The panadaptor offset between the carrier and the IF center can shift as filter width increases because the K3 doesn't let the lower edge of the filter fall below 200 Hz. In CW mode for example, using a pitch of 600 Hz, there is a change in the offset required when the filter width exceeds the point where the IF center can be offset by the CW pitch frequency (where (200 + width/2) 600). I noticed this when hacking PowerSDR/IF-Stage here to make some improvements. The definition for command FI in the K3 Programmer's Reference states: FI * (I.F. Center Frequency; GET only) RSP format: Fi; where represents the last 4 digits of the K3’s present I.F. center frequency in Hz. Example: If = 5000, the I.F. center frequency is 8215000 Hz. Intended for use with panadapters, which need to keep track of the exact I.F. center frequency as filter bandwidths and shifts are changed by the operator. If you don't account for all this the position of the filter passband relative to the carrier frequency isn't displayed correctly on the panadaptor.

Re: [Elecraft] Heathkit Returns!
This Heathkit thread has been very interesting to me as a manufacturer of professional audio equipment that uses a lot of vacuum tube circuitry. When I did the first designs for our products 20 years ago, I had a Heathkit-style assembly procedure in mind. In fact, at one time, I made an assembly manual that copied the Heath format with the check-off boxes, solder or don't solder, etc. When I started out, I was building each unit myself, and as much as I enjoyed it, after a while I thought I was in Heathkit-hell. Now I have six assemblers who do 95% of that work, and they do a better job of it than I could do. I rotate them through the nine products we make so they don't get burned out building the same thing all the time. Parts are readily available for this type of construction. DigiKey, Mouser, and Newark are all on our suppliers list for those components we do not buy in sufficient quantity to purchase directly from the manufacturer. Prices can be high, and for us a major challenge is finding replacements for parts that are become unavailable. But the parts you need to build almost anything are out there if you're willing to do a little searching. Although all our products use vacuum tubes in the audio path, we also use a lot of solid-state components in peripheral circuitry. For example, we build an audio compression amplifier that uses a pulse-width modulator as the level control element (with a FET switch). It always makes me smile to see a printed circuit board with SMT parts on it just an inch from a point-to-point tube socket. We hand-solder all those SMT parts. Take a look at the products we make and you will see how I was influenced by the equipment I loved from the 1950s. www.dwfearn.com 73, Doug K3KW The demand for leaded parts may be lower, but don't count them out. We can still purchase all of the parts for our full kits without any trouble. That's hundreds of different leaded parts from dozens of vendors. (Our full kits include the K1, K2, KX1, transverters, and nearly all of our mini-modules and accessories.) Take through-hole ICs, for example: Digikey shows about 400 different 8-pin DIP dual op-amps in stock from 17 different manufacturers. They stock over 700 types of DIP-package Microchip PIC parts. The SA612AN 8- pin DIP oscillator/mixer found in many ham designs is carried by at least half a dozen vendors, with thousands in stock. Interesting I/O chips like the TI TPIC6595N 8-bit shift register/ peripheral driver are still widely available in DIP packages -- I counted 9 vendors for this part. Or how about a leaded, 10-K, 1/4-watt, 5% resistor? Digikey has well over 2 million in stock from three manufacturers. Finally, consider transistors. I found 21 stocking vendors for new 2N's, and there must be tens of millions of them available surplus. Digikey alone stocks 10 different kinds of TO-92 JFETs.

Re: [Elecraft] OT: Heathkit Catalogs
I know this is getting 'way off topic and extended, but I have been very interested in how pervasive the Heathkit experience is among the Elecraft community, so I'll add my own experience with Heath. I built an AR-15 stereo receiver while I was in the Navy, on an ammunition ship in the South China Sea during the Vietnam war. I can't tell you what a thrill it was to fire it up and pick up an FM station from Manila as we were heading back into port to the Naval Station at Subic Bay. Some years later, I built a Z-89 all in one computer, primarily for use as a word processor. Its Z80 processor addressed 64K of memory (yes, K, not M). The entire CP/M OS was 31K, and it had a BASIC interpreter. It had space to install two 5 floppy drive units, which was a big advance, at the time, over the RadioShack TRS-80, which used a cassette tape recorder for storage. Later, a third party came out with a memory-based hard drive that replaced one of the floppy drives, predating the recent trend toward silicon-based storage by three decades. This served me very well as a line-oriented word processor, using a program called WRITE (Writer's Really Incredible Text Editor), which was developed by sci-fi writer and Byte magazine columnist Jerry Pournelle. For its time, the Z-80 was The Best. Even better, in many respects, than something called an Apple. (There was a competitor called Orange, too.)

[Elecraft] K3/P3 using a MFJ Matchmaker
(The following would be a nice mod to be built into the radios. The f/w could prevent accidental Tx.) I don't know if anything like this has been mentioned before. Furthermore, I don't know how many people use a product like the MFJ Matchmaker (TM) to tune their manual tuners. A similar product is also available by at least one other mfg. I happen to have the Matchmaker. I use open-wire feedline, so I find the Matchmaker very handy. It emits spread-spectrum noise, but doesn't transmit RF. With the unit turned on, one adjusts the tuner for minimum S-meter reading on the radio's frequency. I initially make a quick-sheet of settings for each 50 Khz across the bands and use it to get me in the ball-park when I change freqs. Then I tweak the tuner. Now to the point. With the P3, a nice Vee occurs in the noise at the center of the screen (vfo-A) when the tuner is adjusted correctly while the Matchmaker is turned on. That is very nice when the band is crowded and the signals cover up the noise from the Matchmaker. I don't have to find a quiet spot to tune. I can now quickly tune the tuner right on a frequency in use without causing any interference by watching the P3. It is much quicker for 'search and pounce'. I have taken a picture of what the Vee looks like if anyone is interested.

Re: [Elecraft] K3 #250 now working...no err msgs
I suggest using the little bottle with the thin tube applicator on top (www.caig.com). I have both the spray and the bottle. The spray rather soaks everything in the vicinity which is probably not harmful but certainly wasteful and can have fluid even dripping long afterward. The only place I use spray is in renewing scratchy potentiometers in old boatanchors where I can put the thin plastic straw into an opening and give it a blast (then stuff absorbent paper around the pot to catch all the drips, Hi!) When I got the little 25 ml bottle I thought I'd use it rarely. After more than 5 years of de-oxing countless contacts it's the spray that is almost never used yet the little 25 ml bottle is still 90% full! True it's not as fast as spraying a multipin connector, but it doesn't take long to squeeze a tiny drop on each pin. The manufacturer, Caig, says it contains a lubricant and compound that protects connections from corroding again. IMX, it does just that. 73 Ron AC7AC -Original Message- Gentlemen, Thanks for all your support and suggestions. Dale from Elecraft suggested removing the front panel, spraying the pins with Deoxit.

Re: [Elecraft] K3 err msgs on powr up?
Wayne, Would you have an idea which SN, or at least the approximate date, the cut-over to gold-plated connectors occurred? Did this include all connectors, or just the front panel ones? 73, Ken, NU4I GW0ETF wrote: I have K3 #145 and this problem has plagued me plenty in the past. I now know it *is* a problem with the FP connections as Wayne describes. I've more or less stopped it by using Deoxit on the pins; clearly there is an issue with oxidation(?) of the pin surfaces. We switched to all-gold plating on the mating connectors in production. BTW, Jorge states the radio performs normally even when the errors appear. Have you checked for example that the KAT3 works when Err AT3 appears, and that you get 100w out when the PA error appears? Mine certainly didn't. Recent firmware releases allows continued operation even if error messages appear. The problem should be fixed as soon as possible, but sometimes -- like at a DXpedition or during an emergency -- the show must go on. 73, Wayne N6KR __ 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] Heathkit Returns!
I do not even need to reply. Mathew, Wayne, Don have done so eloquently. I think there might have been a point when components were difficult to acquire but not today. There are many specialty houses to make custom pcb's (I use ExpressPCB). But most of my one-of boards are RS project boards (similar to vector board) with spacing for thru-hole mounting. I find I can also use 1206 and 805 sized chips on that board. Mouser, Digikey, Nebraska (surplus) Sales, RF Parts, etc. And my Anchorage-based supplier Frigid-North Co. The biggest issue is having patience for the mail or UPS to bring the components. Not being able to run to the store requires a bit more fore-planning. I also have tried to accumulate common parts like a resistor and capacitor for a personal inventory. I picked up a APC chip cap demo box off one of the prize tables at a VHF conference. Analog Devices offers free samples of almost everything they make. I've gotten samples of two of a lot of AD stuff. Other companies do that too. So I maintain it is hams who have abandoned HB (for whatever reason). There is a healthy HB community in the QRP, mw and eme worlds. TAPR bunch too. The common perception is I can't do that. Well, you do not know until you try. Building stuff is the real joy of ham radio for me. 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-100w, 1296-60w, 3400-?

[Elecraft] P3 - KXV3 Gain Mod Question
Had a nice QSO with Dwayne, KE5EFY this AM and got quite a bit of my new P3 set up. It appears to me that everything is working as it should, I got S-units to appear on the ordinate [they mean more to me than dBm on HF], got a few Fn switches set, and he walked me through the PEAK/NOT PEAK toggle. When I started building, I installed the KXV3 first, and had the K3 back on the air before I started the P3. In the P3 stuff, there was an IF Gain Mod, change one resistor on the K3 RF board. I had already re-installed the countable infinity of chassis screws into the K3, and screwing around with an SMD the size of a grain of pepper didn't really light my fire, so I put it aside. Now, with everything working just fine, I'm wondering what that mod really does? Do I need it? Incidentally, while installing the KXV3, I needed to cut jumpers W1 and W2. This is easier said than done. They are right up against a board that I wasn't told to remove.

[Elecraft] Power Werx S5-30DV Switching P/S Heads Up
I recently acquired two Power Werx S5-30DV Switching Power Supplies. While the P/S are nice and small, work on 110 / 220 and easily powered my K-3 and TS-480, BEWARE... The P/S come from the factory set for 220V (Slide Switch Selection on the back) The documentation sheet with the P/S doesn't mention the factory default setting of 220. If you power a K-3 or most likely any other rig without changing the input voltage setting to 110 if you run the P/S on 110 and don't change the input voltage switch to 110, you will have terrible AC on transmit when the RF level of the radio is increased over 10 Watts. 73, Jack W0UCE __ 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] P3 - KXV3 Gain Mod Question
Fred, Look at that mod on the Elecraft website - click on the K3 Mods + Application Notes. There you will find that the mod has been included on all new K3s since about 9/01/2009. If your K3 is older than that, the mod is needed - if it is quite near that date, then you should do the test indicated with the mod instructions to see if it is installed or not. If it is significantly later than 9/01/2009, then the mod is already installed. You only need to remove the front bottom cover to check or install the mod. Yes, you need it for proper (calibrated) operation with the P3, and it is shipped with every P3, so some obtain the part even though it may not be needed. If your K3 does not have the change, by all means make it - it is not difficult - alternately heat the ends of the installed resistor until it comes free - wick away the left-over solder from one solder pad - hold the resistor on place gently with tweezers or other suitable tool and heat first the end where you did not remove the old solder, then apply solder to the other end - check for continuity from both ends of the new resistor to the associated solder pad - if zero ohms, job is done - if not, resolder the offending end. 73, Don W3FPR On 9/12/2011 6:17 PM, Fred Jensen wrote: Had a nice QSO with Dwayne, KE5EFY this AM and got quite a bit of my new P3 set up.

[Elecraft] K2 s/n 1769
Every so often the Ham Radio Gods smile upon me. So here I am sitting in Wilkes-Barre, PA, after journeying 850 miles from the Atlanta area to attend our family reunion last Saturday. Due to the heavy rains the Susquehanna river had gone to flood stage and the Wyoming Valley was harder hit this time than in the 1972 Agnes Flood!! The river crested in W-B at 42.66 ft! The highest ever recorded. This flooded the lower areas that were not well protected by the US Army Corps of Engineers levies that were built after the 72 flood and then reinforced and heightened about 4-5 years ago. Everyone was told by the Luzerne County EMA that the levies would hold up to 41 feet. However, they never told anyone about the 3 ft fudge factor that they had included back in 2005!! So even if the river exceeded the 41 ft height the levies would contain it up to 44 ft. OK, so here I am sitting in the hotel room, bemoaning the fact that the reunion was cancelled. Its raining like unto a female bovine urinating on a planar surface of a non-synthesized mineral nodule, so I called a buddy of mine whom I Elmered about 20 yrs ago. After a little ham radio talk he wanted to know if I wanted to buy his partially built K2? Price: $350!! Man, I couldn't get to my wallet fast enough!!! The rains stopped! The sun came out and shown upon my face! I had achieved Nirvana!!! I picked up the rig and the extras on Monday. The radio was completedlacking only the final alignment. In addition to a fully assembled K2 he had purchased the ATU, NB, 160M/RX and the SSB options! None of these had been built and were still in their plastic baggies! So basically I got about a $1000 worth of radio for $350. This is a good thing! I had sold my last K2 to afford our to move from PA to GA about 3 yrs ago. I had regretted that decision for the last three years. Now, with this rig and the options I can add the DSP, and the I/O boards. The firmware will have to be upgraded, as I am sure that this radio, bought around 2001 or 02 has the original firmware. I have a new K2, and will have it on the air as soon as I do the final alignment and put the rest of the case together. I can take my time with the options and get back into some serious building for a change!
