Re: [Elecraft] General Coverage Module (K3)
Hunter, My instinct would be to remove and re-seat that board. That could solve the problem. A defect in the board is unlikely. All this assumes you have the correct mode in your K3 (e.g., not listening to BC band in CW mode). 73, Phil W7OX On 6/6/16 1:40 PM, Hunter Ellington wrote: I have the General Coverage Module in my K3, serial number 6969.

[Elecraft] General coverage bandpa
Harlan, I chose the main receiver since I assumed most casual listening outside the ham bands would not involve both Rx. Also, I use the main receiver on the 500-KHz band for operating with an experimental license. The general coverage board is required to operate out of a ham band in TEST mode. That is how I transmit on the 600 meter band; taking 1mw level RF to drive a modified surplus NDB transmitter (the K3 replaces the original xtal osc.). But I guess it would reduce to a personal decision for deciding which receiver to install it in. 73, Ed - KL7UW From: Harlan hsherr...@reagan.com To: Elecraft Email elecraft@mailman.qth.net Subject: [Elecraft] General coverage bandpass module Message-ID: ryi94mxyxvb12xk8ndr13xd9.1362970670...@email.android.com Content-Type: text/plain; charset=utf-8 For those with the sub receiver and only one bandpass module...

Re: [Elecraft] General coverage bandpa
I put BPF boards in both receivers but if I had only one it would go in the sub RX. 1) I am more likely to use the out of band Rx for listening to the AM Band and using the Sub RX with a separate antenna eliminates the losses associated with the pin diode T/R switch. 2) I am likely to want to use the main RX for normal ham operations while listening to something else (WWV, route weather, SW BC, etc.) and having the second RX available for the SWLing even when using the transceiver normally just makes sense. On the other hand, if I had a need to *transmit* outside the ham bands I would have no choice other than to put the BPF in the main RX. 73, ...

Re: [Elecraft] general coverage receive on KX3
I am not talking about the need to desense because of an IF frequency but that the front end ham band filters may still be active when doing SWL. It is my understanding that the K2 can receive SWL but its front end filters are ham band only so if you are between any ham bands the sensitivity falls off, perhaps quite a bit due to the ham band filtering. so I am really asking if the front end filters of the KX3 can change/switch to accomodate SWL across the most common range of 3-16 MHz. tks Dennis -- View this message in context: http://elecraft.365791.n2.nabble.com/general-coverage-receive-on-X3-tp7559086p7559100.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] general coverage receive on KX3
the kx3 manual describes these front end filters as follows The relay-switched low pass filters are used during both transmit and receive. A few of the filters are dedicated to one band but most cover two bands. The signal on the antenna side of the filters pass through a forward/reflected power and SWR bridge to the HF-6 meter antenna jack (BNC), or to the optional KXAT3 automatic antenna tuner. Latching relays are used to minimize power consumption. The RF band-pass filters are used for both transmit and receive. Filters are selected with low-loss CMOS RF switches. The band pass filters significantly attenuate receive signals at harmonics of the RX frequency, particularly the odd harmonics. These filters can seriously degrade SWL sensitivity at non-ham band regions. Wayne or another designer will be able to answer this question if they are watching this.

Re: [Elecraft] Elecraft General Interest: SFGate: Robert Helliwell, radio science pioneer, dies
Jim, It was possible to hear whistlers from storm centers long before you could hear the thunder. I doubt the whistlers you heard was from a storm that was close enough to hear the thunder: Very low frequency (VLF) radio waves shoot past the ionosphere and into the next region of space, the magnetosphere. Here, the atmosphere is completely ionized. The Earth's magnetic field controls the motions of charged particles, creating channels of ions aligned with the horseshoe-shaped magnetic field lines. These channels trap VLF radio waves, guiding them between opposite hemispheres along a path that reaches up to 15,000 miles from the surface. http://news.stanford.edu/news/2011/may/robert-helliwell-obit-052011.html I visited the lab when I was a freshman (before the advent of dirt) as part of the tour they gave incoming engineering students. -Rex- K1HI Rex Lint Merrimack, NH WWW.QRZ.COM/db/k1hi __ 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

For your information. --O. Johns W6ODJ Begin forwarded message: -- This article was sent to you by someone who found it on SFGate. The original article can be found on SFGate.com here: http://www.sfgate.com/cgi-bin/article.cgi?file=/c/a/2011/05/23/BABK1JIVEQ.DTL - Monday, May 23, 2011 (SF Chronicle) Robert Helliwell, radio science pioneer, dies mailto:dperl...@sfchronicle.com;David Perlman, Chronicle Science Editor When Robert A. Helliwell, a Stanford electrical engineer, heard a mysterious series of high-pitched, drawn-out whistles coming from his laboratory's radio receiver more than 60 years ago, his curiosity led him to a pathbreaking series of experiments exploring Earth's magnetic field and the belt of energetic particles beyond it. With great delight over the years, he regularly welcomed visitors to his lab to listen to what he called his whistlers, the eerie electrical warbling generated by lightning flashes in Canada's Arctic and that had sped for thousands of miles through the ionosphere to Stanford. Professor Helliwell, a distinguished radio science researcher, died May 3 in Palo Alto of complications from dementia. He was 90. During his research, Professor Helliwell once enlisted a powerful Navy transmitter to send signals from Annapolis, Md., to a Chilean listening post in a lighthouse at Cape Horn. It led him to discover that Earth's ionosphere was not 200 miles thick, as scientists had believed, but extended at least as high as 20,000 miles. Continuing that research, Professor Helliwell sent radio transmitters into space aboard NASA satellites to explore the radio properties of the Van Allen Belt, where highly energetic electrons and protons trigger the aurora borealis, the brilliant northern lights. In Antarctica, where the atmosphere was unsullied by radiation from urban power lines and radio noise, Professor Helliwell and his students installed a very low frequency transmitter at Siple Station, a research base 900 miles from the South Pole, and deployed an antenna array 13 miles long. It sent radio signals to Canada and, because the Antarctic ice sheet is 1 1/2 miles thick, the antenna in effect was 1 1/2 miles high above Earth. Little of the very low frequency radio energy, therefore, was absorbed by the ground and the signal from Siple was able to follow Earth's magnetic field lines far out into space before returning to Earth in Roberval, Canada. It was like a lab experiment in space, recalled Donald Carpenter, an emeritus professor of electrical engineering at Stanford and one of Professor Helliwell's former students. He was always a very curious guy, Carpenter said, and if you came to him with a question, he'd answer, but you'd come away with still more questions. He was a gold mine of insights into the behavior of the ionosphere and the magnetosphere, and the Van Allen radiation belts. Professor Helliwell's radio frequency experiments at Siple Station were his crowning achievements, Carpenter said. The scientific world honored him for his work there, and in 1966 the government's Board of Geographic Names named a stretch of mountains along the coast of Antarctica's Victoria Land as the Helliwell Hills. Professor Helliwell was born in Red Wing, Minn., and joined the Stanford faculty in 1946 after earning all his university degrees there. His high school sweetheart, Jean Perham, also graduated from Stanford. And when Professor Helliwell joined the fencing team as an undergraduate, she did too - going on to become the university's first female fencing coach. Mrs. Helliwell died in 2001. Professor Helliwell is survived by his sons, Bradley of Sedona, Ariz., David of Arcata (Humboldt County), and Richard of Colorado Springs; a daughter, Donna of Sunnyvale; four grandchildren; and one great-great-grandchild. A memorial service will be held at the Stanford Memorial Church on June 7 at 3 p.m. E-mail David Perlman at dperl...@sfchronicle.com. -- Copyright 2011 SF Chronicle __ 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] Elecraft General Interest: SFGate: Robert Helliwell, radio science pioneer, dies
The transmitting station SAQ in Sweden regularly puts their big transmitter on the air at 17 kHz. The transmitter is an Alexanderson Alternator - a fascinating mechanical beast that did an excellent job generating pure CW back in the days when most stations were running spark. Google will turn up a wealth of information and photos of it. Of course electromagnetic waves are not sound waves. You can't hear them with only your ears even at such low frequencies. Back in the early days of radio the consensus among the experts was that the longer the wavelength (the lower the frequency) the longer the range, so much effort was put into very low frequency systems that operated in the same frequency range in which we hear sounds. And electromagnetic waves at those frequencies do penetrate earth and water better (Navies still use them to communicate with submerged submarines). It was that flawed thinking that got us Hams pushed onto the useless Short Wave bands were the experts were certain we'd never get out of our own backyards running only a kilowatt or less.

[Elecraft] General Digital Contesting Help
Group, I would like to attempt to try and do some digital contesting with my K3. It took me a long time to get HRD and its associated software working and I finally can use the DM780 software fairly good. What I am not able to figure out is the proper set of calls and responses that contestors are looking for. So can someone point me in the proper direction on how to go about understanding how contesting works and how to log. I have been trying to read up on the internet, but I am missing some basic points of knowledge to pull it together. Thanks in advance for your help.

[Elecraft] GENERAL COMMENTS FROM WB8IDY
I usually don’t comment on these types of forums, and invariably someone will find fault with your comments and take you to task. However; in spite of that I feel burden to share the following perspectives with this group. I have had 69 years of experience, many levels of electronic maintenance, from vacuum type electronics, in the 1950 through large scale integration using computers and digital logic. Through this time the following has happened to me. 1. I have seen the following go out of business – Heathkit, Collins, Drake, and many others. As companies grew larger, they forgot their roots and those things which made their product so great. 2. I have IC 821 that was a great radio. Company after 6years has decided not to support the radio can’t get parts. Solution: Throw it way and buy another radio. The same manufacture has decided not to sell another produce last year because they new they had a lot of field problems because of the complaints of the customer. Their solution was to not support the radio any more. I ask you is that customer service ? We all now the answer. 3. Some manufactures have proprietary hardware chips and software. When you have problems and they have chosen at the corporate level not to support or move support services overseas to off shore companies, what happens. We have all had this happen to us with some computer companies. It is ex-asperating. I could go on, on and on, so here is my point. Elecraft Company is doing it right. Bring jobs back from over seas back to USA. Designing a great product. It appears they won’t leave you in the dark. Your support and further purchases depend on your satisfaction. So lets continue to help support in all ways to make this company stay in business.

Re: [Elecraft] GENERAL COMMENTS FROM WB8IDY
Brian, I will only take a small issue with you. I agree we should support any company that brings good, cost effective products to the HAM market. And yes the company should support these products for a reasonable period of time. But as soon as these products become non competitive, just because they are from a US company, does not mean we should buy their products.

Re: [Elecraft] GENERAL COMMENTS FROM WB8IDY
I don't disagree with Brian's plaudits for Elecraft's focus on customer service but that wasn't the primary reason that the companies he sited went out of business. In a book entitled The Innovator's Dilemma, the author showed that large companies get caught when technologies change. Heath, Drake, Collins and others were leaders before solid-state technology advanced. They were simply not quick enough on their feet to make the switch to solid state that allowed Yaesu, Icom and Kenwood to eat their lunch. And, now, that software-defined radio has moved from edge-of-the-art to state-of-the-art, those companies are being surpassed as leaders by companies like Elecraft. Historically, leaders in one technology are not able to make the leap as quickly as new innovators who don't have the legacy baggage to drag behind them. IBM led in mainframes, but DEC and HP led in minicomputers, and so on. Nokia led in cell phones, but is having its lunch eaten by Apple, HTC, LG and Samsung in smartphones. Customer service is just one part of the complex reasons why new leaders emerge.

Re: [Elecraft] GENERAL COMMENTS FROM WB8IDY
I wasn't active in ham radio at the time of Heathkit's demise, so I don't know what they were doing or not doing in the ham radio arena, but they certainly were't lacking for expertise in solid-state electronics. I built their AR-15 stereo radio kit while I was on a Navy ammunition ship in Vietnam, and later built their H-89 computer, which was state of the art at the time, albeit primitive by today's standards. These were very well-designed solid state products. Heathkit had many others, including an excellent color TV that had only one vacuum tube in it - the picture tube. I know they had solid state ham products, such as a two meter amplifier. I have no idea how they stacked up to the competition in terms of quality and value. However, since they were truly leading edge with solid state hi-fi and computer kits, among other things, I am puzzled by the assertion that Heathkit was not able to move from the vacuum tube era to solid state products.

Re: [Elecraft] GENERAL COMMENTS FROM WB8IDY
I believe Heath and Drake had the first two synthesized HF amateur transceivers on the market. (SB-104 and TR-7) And both had solid-state gear before that. I don't think their problems were being late adopting new technology. IMO Heathkit went belly-up because of poor execution on a number of their designs. The SB-104 for example had multiple issues (horrible birdies, poor sensitivity, poor dynamic range, intermittent oscillations, etc.) The reports of Drake's death are greatly exaggerated. Although they no longer manufacture ham equipment the company is alive and well.

Re: [Elecraft] GENERAL COMMENTS FROM WB8IDY
What killed Heathkit was that the Big Three were able to bring products to market that were cheaper and had more features due to mass production and, in the case of Kenwood, had a contempary and stylish product. Heath did not catch up until the early '80s and by then it was too late. To a prospectvie ham (me) looking at a Heathkit catalog from late 1980/early 1981 and seeing their ham offering that had (at least to me) an early '60s styling to it caused me to look elsewhere until they introduced an up-to-date kit in 1982 or so. That said, I did build an HW-8. But the TS-520/820/530/830 models were certainly attractive to me. Also, the Big Three owned the VHF FM market early on due to frequency synthesis and memories in a small (for the time) attractive enclosure. Even in performance oriented amateur radio styling plays a part. 73, de Nate N0NB -- The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true.

You could say the same of me and Elecraft - I new of Elecraft's reputation and many of my club friends have K2s, but I was not happy about the looks and display of the K2 (ok, so I know better now). I was about to buy an FT-2000 when the K3 was announced - that was it for me - I put the money into the K2 on 2nd May 2007, one of the first buyers and I paid for a fully loaded K3 up front - I'm very glad I did (but it was a long wait :-) 73 de M0XDF, K3 #174, P3 #108 -- Times are bad.

Re: [Elecraft] General Coverage Question - K3
I've not got one in my radio but you should be able to hear it click in as you tune well out beyond the edge of a ham band. So maybe put it into really coarse fast tune mode and head off the top end of the 80 meter band until you hear it click into place? You could also pick a frequency way between bands and turn the KBPF3 on/off and compare amplitudes. Keep in mind I believe that you have to power cycle the radio after making changes to options that are installed. ~Brett (KC7OTG) On Sat, 2010-03-20 at 19:00 -0500, Don Cunningham wrote: Well, I have completed K3, s/n 4076 and all checks well at the low power level with one exception.

Entering a direct freq is easy... Press FREQ ENT (red button high right from the knob). Then use the red numbers to enter the freq (and you can abbreviate).

DSP noise blanking is applied after the hardware AGC, as in all other rigs I know of that include DSP NB, but I believe it is pre-DSP-AGC. Lyle may want to comment on this. I know we spent about a year optimizing the gain balance! 73, Wayne N6KR On Dec 8, 2009, at 9:39 AM, Duncan Carter wrote: Is the DSP blanker input level also subject to AGC?

[Elecraft] General Coverage Receive Module
I see that the general coverage receiver module can be installed in either the main or sub-receiver. I was planning to install it on the main board as I have the widest filter (13MHz) there. But before I do, I wanted to hear some pros and cons for installing on either board.

Mike, I believe it can be installed in both receivers - 2 modules would be needed. I like to monitor 10 and 15 mhz. Also like to monitor the 10 meter beacons.

[Elecraft] General Covverage Receive
Wayne, Lyle. and Company, I have a K2 and enjoy it very much, however, the one thing I wished it had was General Coverage on the Receiver. With the announcement of the K3 I see there is something about it but not much has been stated as of yet. What is the Freq. Range of the General Coverage part of the K3 and can one use all the bells and whistles between the Ham Bands that are available on the Ham Bands, as far as receive goes? I enjoy now and then going between the bands to see if there is any Intelligence there.

Re: [Elecraft] General Covverage Receive
Hi Joe, Yes, you can add general coverage receive filters to the main receiver and/or the subreceiver. This is the KBP3 option (see order form). The rig automatically selects the narrow ham-band filters when you're in the ham bands, and the wider filters when you're in-between ham bands. This option has no effect on ham-band performance and is extremely easy to install. 73, Wayne N6KR John Kinnunen wrote: Wayne, Lyle. and Company, I have a K2 and enjoy it very much, however, the one thing I wished it had was General Coverage on the Receiver.

[Elecraft] General SMD Soldering Question
This is distantly related to the mainstream of QA on this net.I intend to use my new K2 to drive a Icom IC-2KL amplifier. Please imagine for now, there is an intermediate amp between the K2 and the 2KL. One of the twin PA boards on the 2KL ( a backup, I have 2 of them) is unfortunately, smoked. My immediate task is to solder a pair of 1KV Syfer ceramic SMD 0.1 mfd caps between two troubled pcb tabs in the PA output coupliing stage, where the previous incumbents were vaporized, by previous owner. I think he/she ran it into a low R/high C load on 80 or 160. This is a heavy solder job at least as heavy as the KPA100 (judging from the manual). I think I may need to solder extension tabs to the caps, which are about 5mm wide, to bridge a 10-15mm gap between the tabs on the PA board. Of course, I need to clean up all the carbon residu on the PA board and tidy up the tabs first. How does one go about this task? Is a solder iron loke a Hakko 936 the best tool or should I use a hot air SMD soldering unit or even an oven? Should I use solder paste or ordinary 63/37 Kester 44? What temps shuld one use? I normally run the Kester 44 at 750F, as per the recommendation on their website. Comments much welcomed.

RE: [Elecraft] General SMD Soldering Question
Wyn, If you have the hot air gun or oven and solder paste and know how to use it, by all means go that route, but if not, then just use the Hakko - you will be soldering two widely spaced tabs on the capacitors rather than finely spaced leads like are encountered on SMD ICs. Yes, the Kester 44 will work just fine if the diameter is small enough to properly control the amount of solder applied. If the copper area is large, crank the heat on the Hakko a bit higher or use a larger iron. Since you have a 15 to 20 mm gap on the PC board, why not use capacitors with leads rather than the SMD variety (unless you already have the SMD caps in hand). The extension tabs that you add will likely have just as much inductance as the capacitor leads. Of course, if this amp is for use at VHF/UHF, then any extra inductance may matter, but likely not for HF. 73, Don W3FPR -Original Message- This is distantly related to the mainstream of QA on this net.I intend to use my new K2 to drive a Icom IC-2KL amplifier.

[Elecraft] General Trasverter Operation Question
I am using a cross-needle, MFJ tuner in between my XV-50 and antenna. The interaction between the tune and transverter is confusing me a bit and I was wondering if someone could educate me as to what is going on? I set my transverter output power to something around 20 watts, as measured on the XV-50 LED display ... then put K2 into tune mode ... and then adjust the controls on the tuner to minimize the reflected power and maximize the forward power, which has the effect of minimizing the SWR (indicated by the crossover poinit of the two needle indicators). At least, that is what I think I am supposed to do. But as I do this, as I lower the SWR indicator on the tuner, the power output on the XV50 goes up into the red zone, lighting up all of the LED's on the front panel. This worries me, and I then back off the power control on the K2 until I am back to 20 watts or so as measured by the XV-50 display. Am I on the right track here? Or am I doing something stupid?

Why would you need a tuner between the K2 and the XV-50?

RE: [Elecraft] General Trasverter Operation Question
That's normal Joseph. Here's what's happening. The XV output power is determined by measuring the RF voltage at the antenna connector. That is converted into a level that lights the power LEDs. The problem is that the output power measurement is ONLY accurate when the XV is terminated in a 50-ohm non-reactive load. As you adjust your tuner for a low SWR, you are changing the load the XV sees and so its output power indication is thrown off. Simply use enough output power to get a good indication on your SWR meter, then adjust things for the lowest SWR you can get while ignoring the LED power indicator. Then, when you have the SWR set to minimum, set your K2 output for 20 watts (or whatever you want) indicated on the XV. As long as the SWR is very low when you set the power level, it'll be accurate.

RE: [Elecraft] General testing for key clicks: AGC
Thanks, guys. It seems my problem was one of absent mindedness. I had left the noise blanker on in my 930. The result was that I was hearing K2 key clicks that weren't actually there. Once I disabled the noise blanker, things sounded great. As you two noted, the AGC was not affecting the testing. I also took a look at the RF envelope on my scope and was pleased to see what Elecraft had shown in the key click mod document. -Michael N9BDF = Vic, K2VCO wrote: I doubt that it matters.

The only thing that should be added to Vic's procedure is that you should keep the power output of the transmitter being tested down enough so that the signal in the monitir receiver is S9 or less. I've tested many rigs for klix monitoring in of my many ham receivers and AGC on/off does not make a bit of difference, as long as you do it as Vic and I described (which is the *only* proper way).

I doubt that it matters. What *does* matter is that you must listen *away* from the transmitter's frequency. To check for clicks, use your narrowest filter and tune off the signal frequency, both up and down. If the transmitter is producing clicks, you will hear them when the actual signal is outside the passband. Some rigs produce clicks 3 or more KHz from the frequency. Some people think that you check for clicks by listening to the signal and hearing how 'hard' it sounds. This is not the case; you can easily soften the signal to your ear by using a narrow filter. The real test is is the transmitter generating click energy away from the signal? -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Michael N9BDF asked: Should the receiver's AGC be disabled when testing a transmitter for key clicks -- does it matter? Does it make the transmitter sound worse or better? Yes, AGC can make the clicks worse, but the BIG issue is to avoid putting too much signal into the receiver. Unless your rig is no 'louder' (or registers on the S-meter no higher) than other signals on the band when you key your rig, what you hear is probably not what others hear. You'll hear stuff that's not audible a few hundred feet from your shack. AGC attack characteristics can make clicks worse, and if you are hitting the receiver too hard the receiver itself will produce clicks for you that aren't on your signal.

The only thing that should be added to Vic's procedure is that you should keep the power output of the transmitter being tested down enough so that the signal in the monitir receiver is S9 or less. I've tested many rigs for klix monitoring in of my many ham receivers and AGC on/off does not make a bit of difference, as long as you do it as Vic and I described (which is the *only* proper way). BTW, of the many rigs I've checked for klix, the K2 with the click mod is the cleanest of all. I believe the click mod is now incorporated in all new K2 kits. 73, de Earl, K6SE ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] general
G3RXQ's suggestion that Maybe the reflector could be sub-divided ? is a good one. I have to go thru the list and delete all the K2 info before I am ready to start reading. How about: K1, the one I want most. KX1, I would read this also. K2 K2 add ons Antennas, realliy important to me. General, so that I get the news of nets and EQP etc. All subject lines should start with one of the previous catagories. Maybe some day I will get a K2, then I can change my preferances. 73, Ty, W1TF __ Do you Yahoo!? Yahoo!

Re: [Elecraft] General Coverage
Bob, It is not abnormal - the amount of out-of-hamband range may be slightly different from one K2 to another. You may be running out of VFO tuning even though the numbers change. If you want to verify, check the voltage at the left end of R30 on the RF board. If it is less than 0.5 volts or much over 7.5 you have run out of range and it will tune no further. 73, Don W3FPR - Original Message - I'm the builder of #4175 and have a question concerning the lower end of the spectrum. I was attempting to listen for the VFO of the 2N22-40+ that I'm building at 2085-2185mhz. I don't hear the VFO nor do I hear anything else down there. I tuned into the AM broadcast band and couldn't hear a single station. Is this normal for the K2 or do I have a problem? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] General Coverage
That's normal because of the way the dial works. In normal operation the dial readout is not directly related to the VFO frequency. It's what the logic *assumes* would be the frequency, assuming the local oscillator can tune to it. There's no direct measurement of the local oscillator. The local oscillator frequency is only measured in CAL PLL. When you run the CAL PLL, you look up the internal counter to the L.O. output and the K2 logic measures the frequency of the L.O. at various tuning voltage levels. It then creates a table of values that says If a tuning voltage of 'x' volts is applied to the L.O. tuning, then the receiver ought to be tuned to 'y' kHz. And it's that 'y' kHz frequency that is shown on your dial in normal operation. Think of it as an old analog dial with numbers written on the face so you can see what frequency it's tuned to by seeing where the pointer is on the dial. Running CAL PLL tunes the K2 across the tuning range and writes numbers on the dial at intervals so you can see what frequency you are tuned into when you are operating. Unlike the old analog dial, there's no hard stop at each end of the range saying that you can't go farther. It'll just let you keep tuning and tuning and tuning. So, if you tune outside the L.O. range, the numbers will continue to change on the dial, even though the local oscillator can't be tuned to that frequency.
