Re: [Elecraft] K3 Variable amp keying delay not long enough!!??
I would be tempted to replace the 120VAC relay with a dc relay and key it directly from the rig. Don't forget to fit a diode across it to squash the back emf. This may have other ramifications and might not be this simple, but it's well worth consideration. David G3UNA The FAQ for the K3 promised a 0-50 ms amp keying delay. We got only 0-20 ms in the latest release.I don't think 20 ms is enough in my case, based on my primitive research. Several experts have said mine might need as much as 30-35 ms. My amp's relay is a 30 yr old Potter Brumfield open frame model with a 120vac coil. To make things worse, since the K3 will not switch 120vac, I must use another relay with a 12vdc coil in the line between the K3 and the amp, which in turn pulls in the PB relay. This exacerbates the matter by taking even more time, and I'm afraid to try anything for fear it will damage the K3 and the amp. Am I wrong?? Anyone care to comment?? One of the many reasons I bought the K3 was to be able to operate at least semi break in CW and VOX with my old amp without hot switching, by virtue of having ample switching delay. I've waited months for the feature and am disappointed.. However, I hasten to add this: As a K2 user/owner/builder, I expected much in the K3. I got much more than I expected. I gave up a nice Icom Pro 3 for the K3 and don't miss the Pro 3 one iota. The K3 is unbelievable in what it can do and how superbly it does it. And getting new firmware is icing on the cake.

Re: [Elecraft] K3 Variable amp keying delay not long enough!!??
Some lack of communication between Greg and Wayne I expect regarding the published figures. Luckily, this is a simple thing to fix one would hope. I sent in a list of relay transit times on 2nd April. It was quite clear that 20mS was needed for the smaller coaxial relays like the very commonly used CX540 and up to 50mS for the very high power relays that you might use on a 1.5kW 6m amplifier. I was surprised to discover the maximum delay was set to only 20mS as this is not enough; a margin is needed. The CX540 is common and http://www.nts-electronic.com/cx540d.htm tells me it takes 20mS to engage and 15mS to release. Tohotsu relays are very common. The CX230, CZX3500, CX600, CX800, CX140 and CX120 are often used in amateur applications (because they are cheap). They also all specify 20mS. For really high power SSB electronics (Germany) do a specialist range of relays. These specify 30mS for the HF400 series, 40mS for the HF500/1500 series and 50mS for the HF4000 series. wayne burdick wrote: George, Before settling on a max of 20 ms we looked at a number of amplifiers and got input from several experts.

Re: [Elecraft] K3 Variable amp keying delay not long enough!!??
Hi George, you are right with 20ms limit, it is also little bit short for complex system like VHF/UHF EME station or similar extreme.

Re: [Elecraft] no issues with output power on ssb!
Fern, I urge you to keep up-to-date with the firmware, maybe not updating immediately new firmware comes out (as on the very day), but certainly within a few days (weeks at most). A lot of us will download ASAP in order to help spot problems and advise Elecraft accordingly, only with our help can they find the more obscure problems. That's not to say they don't test and double test etc., but some issues are so obscure, only a certain operating condition or way of using the K3 will find it. If you want to use things like the second receiver or digital voice recorder, you're going to have to upgrade anyway. It is impossible to write code without a bug (I should know, I've been trying to do so for the last 38 years), I defy anyone to be able to do it. When the code is of firmware of this sophistication, it becomes even harder. There will inevitably be issues, the significant thing with Elecraft's code is the great lengths and effort they go to, to find and reduce the bugs and their response to bug reports and the speed at which they fix problems.

In supporting the Triode Board and Tetrode Boards, I have often measured 30ms switching delays in typical older amplifiers that use 2-pole and 3-pole open-frame relays. Such amplifiers are still being used in very large numbers - and indeed they are still being manufactured. Since the K3 will be used with a wide range of unknown amplifiers, a 20ms delay is not long enough to guarantee there will be no contact arcing when the RF appears. To make things worse, since the K3 will not switch 120vac, I must use another relay with a 12vdc coil in the line between the K3 and the amp, which in turn pulls in the PB relay. This exacerbates the matter by taking even more time, and I'm afraid to try anything for fear it will damage the K3 and the amp. Am I wrong?? Anyone care to comment?? That is correct. Attempting to switch 120V AC will damage the K3, and an intermediate relay will add even more delay. But we have to draw a line somewhere. At some point we have to stop blaming the transceiver manufacturer, and accept responsibility for modifying the amplifier. The modern interface standard is that the amplifier PTT input has an open-circuit (unkeyed) voltage of no more than +12-15V DC, and that the amp can be keyed by switching this input to ground with a current of a few milliamps. All modern transceivers meet that interface standard, and the K3 meets it very comfortably. Amplifiers that require high-voltage, AC or negative switching are 30 years behind the times. If the owner wishes to use the amplifier with a modern transceiver, I think it's clearly his responsibility to bring the switching interface up to date. Every design is different, but modifications are out there on the web, and none of them should take more than an evening's work. If Elecraft can move a little too, by stretching the maximum keying delay to at least 30ms, then everyone could be happy. With a little more effort, some of these slow relays can be speeded up electronically, without the trouble of changing to faster relays. The link below gives details of a circuit that can be used to speed up any RF relays operating from a +12-24V DC supply: http://tinyurl.com/6n8wjg -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek/boards ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2: What do you have in your portable/travel kit?
A type of antenna that I keep packed for use at short notice is a halfwave centre fed dipole for use as a vertical, where part of the coax feeder forms the bottom half of the dipole. With this arrangement the coax feeder comes away from the bottom of the antenna not from the centre, radials are not essential and matching is easy. The complete antenna and feeder could be made using a single length of coax. Although it is a single band antenna there might be a modification, which I have not yet tried, to get it to work well on two perhaps three bands. I have used this scheme to feed Half Squares and other types of phased vertical arrays.

Re: [Elecraft] K3 Variable amp keying delay not long enough!!??
Ian, Your remarks are quite appropriate. My question to those needing 50ms delays is: What are you doing now with your XYZ radio? The sequencing problem for complicated VHF/UHF setups is complex. Just delaying the RF out of the transceiver is an unlikely complete solution. It almost always requires lots of external hardware and sequencing logic/delays that is specific to the harware being used. Designing and building that is part of the endeavor. I don't understand why people are so adverse to using the inhibit line provided by the K3. It will prevent hot switching. BTW people using AC relays should be aware that they will also operate just fine on DC. (115vac relays work fine on 24VDC). Once converted for DC operation, they can be speeded up by methods like you point to. 73 de Brian/K3KO -- View this message in context: http://www.nabble.com/K3-Variable-amp-keying-delay-%3E%3Enot-long-enough%21%21---tp17139573p17146677.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

On HF, I tried the no counterpoise antenna by M3KXZ with very disappointing results. On VHF, I've had good results with the coax antenna by LA1IC described (in Norwegian!) at http://la2t.org/teknikk/vertikal2m.html. Choking off the radiating part of the coax is challenging, because we're trying to choke a voltage node. I was told that the coil which terminates the radiating part of the coax on the 2m antenna is chosen to resonate as a parallell trap at 2m with its stray capcitance. On the HF antenna, I just wrapped the feeder around a large toroid 10-15 times, and that did not work well. My 2m antenna needs are modest, so take this with a grain of salt. 73 LA4RT Jon ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 60m setup?
While playing with my K3, I selected 5.0 mHZ for WWV using manual Freq ENT. When I then changed bands with the rocker switch the bands would go from 80m to 5.0 to 40m. I vaguely remember seeing one of the 60m freq 5403.5 when I first fired up the rig back in March. Did I inadvertently erase the 60m channels or were they never there? I looked thru the manual but could only find on page 37 how to set up Channel Hopping. Are programmed memory freqs how we access 60m? I then manually programmed the 60m freq into Memory 1-5 and included the * for channel hopping...however, the MV did not work to save the freq..so then I went to page 16 and programmed the memories via VM. So now I have the 5 60m freq in memories 1 thru 5. When I try to start scanning (Channel hopping) by holding 'Scan', I get Set A/B on the lower LCD. I tried to put 5330.5 in A and 5403.5 in B and press 'SCAN'. Then it said MV req. I set memory 1 to 5330.5 and B vfo was 5403.5..So I followed the instructions of MV and set #1 memory and tried 'SCAN' agn...this time the B vfo defaulted to 5.000 mHZok, I give up...what am I missing? 73 Tom ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Once converted for DC operation, they can be speeded up by methods like you point to. Two points there - The first one is, it does not fail safe if the connector is unplugged for any reason. The same applies to sequencing via an external PTT source if the radio defaults to VOX on CW. Feedback is always going to be the best way as long as it can not be bypassed by mistake. What you should do is both requiring a minimum delay to occur before transmission and also use the inhibit line. The second is a most useful tip. How general is this or is it only some coils have the correct impedance/resistance ratio? Will there be any other issues? What about long term dissipation?

Luckily, this is a simple thing to fix one would hope. I sent in a list of relay transit times on 2nd April. It was quite clear that 20mS was needed for the smaller coaxial relays like the very commonly used CX540 and up to 50mS for the very high power relays that you might use on a 1.5kW 6m amplifier. I was surprised to discover the maximum delay was set to only 20mS as this is not enough; a margin is needed. The CX540 is common and http://www.nts-electronic.com/cx540d.htm tells me it takes 20mS to engage and 15mS to release. Tohotsu relays are very common. The CX230, CZX3500, CX600, CX800, CX140 and CX120 are often used in amateur applications (because they are cheap). They also all specify 20mS. For really high power SSB electronics (Germany) do a specialist range of relays.

I vaguely remember seeing one of the 60m freq 5403.5 when I first fired up the rig back in March. Did I inadvertently erase the 60m channels or were they never there? I looked thru the manual but could only find on page 37 how to set up Channel Hopping. Are programmed memory freqs how we access 60m? I then manually programmed the 60m freq into Memory 1-5 and included the * for channel hopping...however, the MV did not work to save the freq..so then I went to page 16 and programmed the memories via VM. So now I have the 5 60m freq in memories 1 thru 5. When I try to start scanning (Channel hopping) by holding 'Scan', I get Set A/B on the lower LCD. I tried to put 5330.5 in A and 5403.5 in B and press 'SCAN'. Then it said MV req. I set memory 1 to 5330.5 and B vfo was 5403.5..So I followed the instructions of MV and set #1 memory and tried 'SCAN' agn...this time the B vfo defaulted to 5.000 mHZok, I give up...what am I missing? 73 Tom ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3: Older Amps - small rant
I just one to make a point that there are so many older amplifiers out there (SB-200, 220, 221 to name a few) that it will take another decade (if not more) to get them all out of circulation. Why? Because they are cheap right now. Look at the price of an Acom, Alpha, or a QRO and the price of the SB series or the L4/L7 series is quite appealing. An L7 went for $1600 on E-bay the other day while the next week, two other L7s went for $900. Prices for used amplifiers are all over the place but seem to be high. The SB Series go for $500 to $800 dollars while the Ten Tecs, Alphas (depending on model) and the like go for $1200 to $2300. Even the Ameritrons of the 800H and higher ilk are going for $1700 to $2400 dollars. Some of the more expensive amps still have open frame relays in them which is cheap, but is not what the customer wants or needs. Going to vacuum relays or PIN diode switching just adds to the cost of the unit. So there are a plethora of older amps out there that are using open frame relay for T/R...which means slow. Yes, there are ways of speeding them up, but most people don't bother. The old SB series are so numerous and many people do not take the time to upgrade the T/R circuitry because it is tricky to do. If you are an appliance operator I doubt that you would tackle it. But, for a around a $100 bucks these older amps could be upgrade with vacuum relays The amplifiers are becoming more expensive because of the expense of parts...tubes, switches, etc. Tubes are outrageous except for the Chinese 3-500Z and the 811A and maybe the 572. The cost of the 3CX800 and the 8877 are just through the roof. The older, slower amps, will be around for a long time. It is about dollars. Not everyone can afford the Acom, Alpha, QRO, Command Technogies, or the Ten Tec. (Used or New) I appreciate the time and effort that Wayne and the crew are doing to have the K3 interface with these older amps. I am just not sure how they are going to work out the Knife Switch issue. Lee Buller K0WA In our day and age it seems that Common Sense is in short supply.

Ian White GM3SEK wrote: That is correct. Attempting to switch 120V AC will damage the K3, and an intermediate relay will add even more delay. snip Amplifiers that require high-voltage, AC or negative switching are 30 years behind the times. If the owner wishes to use the amplifier with a modern transceiver, I think it's clearly his responsibility to bring the switching interface up to date. Every design is different, but modifications are out there on the web, and none of them should take more than an evening's work. I agree. One simple modification that you can make without changing the relay is to provide a 28-30 volt DC source in the amplifier. This will operate a 120 volt AC relay reliably (and may make it quieter, too). The K3's switching circuit will handle 30vdc easily.

Re: [Elecraft] K3 Variable amp keying delay not long enough!!??
Hi George! We start to bump up against shortening the first dit on CW when delays longer than 20 mS are selected. We'd certainly like to support longer TX delays, but it will take a little head scratching and f/w work to make it happen. We'll certainly strive to do as much as we can in this area. If you and other members on the list can send me the max delay supported by other rigs currently on the market, that will help us figure out if this is reasonable. I was unaware of any commercial rig supplying much above 20-25 mS of keyout to RF delay. The K2 provides 10-12 mS of delay and we've had very few complaints even with that. What delay does the Pro-III support? Were you able to drive your amplifier in semi-break-in with it? I am unaware of any current production Ham rig that supports directly keying high current AC relays with greater than 20-25 mS long delays. (But I could be wrong :-) That's why many VHF ops, who require long delays for their transverter and antenna switch chains, usually use a foot switch to manually key everything before generating RF. One other thought, just looking at the theoretical worst case relay settling time may overstate the delay required. What is the time delay for the amp RF path itself? Also, the worst case settling delay is usually specified for DC or low freq AC loads. At RF, the contacts may be close enough, with enough contact to provide a very low impedance RF path well before this time, even if they are still settling. In any case, we'll keep looking at this. 73, Eric WA6HHQ == George wrote: I don't think 20 ms is enough in my case, based on my primitive research. Several experts have said mine might need as much as 30-35 ms. My amp's relay is a 30 yr old Potter Brumfield open frame model with a 120vac coil. To make things worse, since the K3 will not switch 120vac, I must use another relay with a 12vdc coil in the line between the K3 and the amp, which in turn pulls in the PB relay. This exacerbates the matter by taking even more time, and I'm afraid to try anything for fear it will damage the K3 and the amp. Am I wrong?? Anyone care to comment?? One of the many reasons I bought the K3 was to be able to operate at least semi break in CW and VOX with my old amp without hot switching, by virtue of having ample switching delay. I've waited months for the feature and am disappointed.. However, I hasten to add this: As a K2 user/owner/builder, I expected much in the K3. I got much more than I expected. I gave up a nice Icom Pro 3 for the K3 and don't miss the Pro 3 one iota. The K3 is unbelievable in what it can do and how superbly it does it. And getting new firmware is icing on the cake.

When Wayne revisits this feature, a reasonable goal would be 30ms, which would accommodate the vast majority of HF amplifiers. (The FT-1000 series have the same adjustment range.) Whatever the transceiver/amplifier combination, the way to adjust the transceiver's key-down delay is to use a low level of drive, and start at the maximum delay the transceiver can provide. Progressively shorten the delay until severe clicks begin to appear at key-down, because RF is arriving before the relay contacts have fully settled. Then increase the delay to a safe value at which no clicks appear, even at full power. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek/boards ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2: What do you have in your portable/travel kit?
Hello Jon, My apology for a slow response, waging war with the grass all day! To terminate the radiating part of the coax I use a high impedance trap whose inductance is a length of the incoming feeder wound as a solenoid, with the turns spaced slightly. To determine the capacitance required to resonate the coil formed by the outer of the coiled coax I use an air variable capacitor, then replace it with a length of open ended RG-213 as the capacitor. The important thing to note here is that the capacitor made using coax must not be connected as an open ended stub, which could upset the trap. I would also suggest that relying on stray capacitance to resonate a trap is a questionable approach. During my first attempt I used a large quantity of cores over the coax which did not work well because the choking impedance was too low, in fact I blew some! With this method of feed it also becomes a relatively simple task to feed a top loaded T antennas from ground level without the use of a high impedance matching network, placing the current maximum at the top. For multiband use I had considered using Close Coupled Resonators in a fixed installation, but not for something to be rolled up. Thank you for the link to LA1IC's antenna, much appreciated. 73, Geoff GM4ESD Jon K Hellan LA4RT wrote on Friday, May 09, 2008 1:28 PM How do you terminate the radiating part of the coax? I've tried antennas based on this principle both on HF and 2m. On HF, I tried the no counterpoise antenna by M3KXZ with very disappointing results. On VHF, I've had good results with the coax antenna by LA1IC described (in Norwegian!) at http://la2t.org/teknikk/vertikal2m.html. Choking off the radiating part of the coax is challenging, because we're trying to choke a voltage node. I was told that the coil which terminates the radiating part of the coax on the 2m antenna is chosen to resonate as a parallell trap at 2m with its stray capcitance. On the HF antenna, I just wrapped the feeder around a large toroid 10-15 times, and that did not work well. My 2m antenna needs are modest, so take this with a grain of salt. 73 LA4RT Jon ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Only thing different from yeste4rday -started on new band RTTY (12m - no QSO with K3 there before) - had to change to FSK-D. Firmware - latest.

[Elecraft] K3: One year and many thanks
Next week is an anniversary of sorts. It will have been a year since I first put my hands on a K3 at Dayton. N6KR was pretty busy at the Elecraft booth but I did have an opportunity to tell Wayne that I considered the K3 a risk-free investment. Only a couple of weeks prior, on May 5, 2007, I had given Elecraft my 50 percent deposit. I haven't been disappointed. This past year has produced some of the best fun I've ever had in 46 years on the air. The Elecraft reflector, for one thing, has been a total riot! I'll clamber out of bed before the break of day to read what has become a global seance on everything from the K3 to the nuances of radio station grounding. I'll laugh. I'll wince. I'll shake my head in amazement at the level of expertise that's so apparent in many posts. Beyond that, the colorful tapestry of personality and opinion, unfolding as it does in real time, highlights the best that ham radio and the Internet have to offer. Most of the time :) For me, the K3 represents a kind of hardware platform upon which the envelope of HF performance / features can be explored and expanded via software. Being even a small part of the dynamic, collaborative evolution of the K3 is at least half the fun. The other half arises from the sheer pleasure of operating a radio at the top of the competitive heap. The conduit for all this enjoyment is the corporate culture at Elecraft - sometimes referred to as The Mojo - which allows each of us to feel as though we are somehow part of the company. That's leadership, pure and simple, and I'm grateful for it. The usual disclaimers apply. The personality, feel and capabilities of the K3 will mature over time, but hopefully it will be a long while before this radio is considered a finished product. Meanwhile, I'm just having way too much fun. Hope to see ya'll in Dayton. And many thanks. 73, Bill, WA4KBD K3 #0224 K2/100 #5473 -- View this message in context: http://www.nabble.com/K3%3A-One-year-and-many-thanks-tp17156641p17156641.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] coaxial dipole (was: What do you have in your portable/travel kit?)
To make a coaxial dipole strip the external insulation from the end of your coax to a length about 10% longer than 1/4 wave. This leaves just shield (braid), center dielectric, and center conductor. push back a bit of the braid so it increases in diameter. Fold it back over itself and carefully stretch it backward until it covers the remaining external insulation leaving just the center conductor and center dielectric exposed. The folded-back braid should now form a cylinder over the coax. Trim this braid until it is 1/4 wave long. Trim the center conductor until it is also 1/4 wave long. You now have a dipole that is end-fed. The folded-back braid functions as both radiator and 1/4-wave stub to cancel the currents on the shield of the coax. For 2M I put this whole thing in a piece of PVC pipe and shoot in some foam insulation to keep things in place. It works just peachy. Caveat: you may find that turning the braid inside-out to make the outer element to be a real challenge. You can cheat by cutting the braid off, compressing it so it slips over the outside of the coax, and then reattaching it to the shield of the coax with solder. To be honest, that is what I usually do. ;-) Brian Lloyd Granite Bay Montessori School 9330 Sierra College Bl brian AT gbmontessori DOT com Roseville, CA 95661 +1.916.367.2131 (voice)+1.791.912.8170 (fax) PGP key ID: 12095C52A32A1B6C PGP key fingerprint: 3B1D BA11 4913 3254 B6E0 CC09 1209 5C52 A32A 1B6C ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 Alignment Problem Still Unsolved...
Still trying to align the filters on my K2, but was getting no indication the Frequency Counter Probe Assembly was working. So I ordered a new and and still nothing (when touching the side of C22, when doing Cal Fctr or Cal Fil). Removed the DSP filter, AF filter and Control Board. Cleaned and checked all contacts. Still nothing. Rig works fine on CW and SSB at 100 watts, but the filters can't be changed. Is there some menu setting I'm missing that allows the Freq Counter to work? Any ideas where I might check next? Thanks in advanceJay, W6JDB ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] [K2] SN6281 0n the air
I'm pleased to announce that the construction of K2 SN 6281 has been successfully completed by the students of the Dos Pueblos Amateur Radio Club ( Dos Pueblos High School, Goleta, CA) with the new Call Sign of KI6PRK, and is now on the air. The newly completed rig is a K2/10 with KAT2, KIO2, KSB2 and KDSP2 installed. No particular difficulty in building, one toroid (K1 on KAT2) needed to be rewound. After comparing it to the drawing it was found to be a mirror image. As a comment, were this a simple inductor or transformer, it wouldn't have mattered. But, as the pickup point for the SWR bridge, the mirroring of the windings causes the single turn pickup loop to work in reverse - swapping the apparent Forward and Reverse currents. As I told my students when they found this, if the Elecraft manual says 'exactly like the drawing' they mean it! We have a VE session this Saturday - getting ready for FD. 73 de WA6VNN, Al Trustee of KI6PRK **Wondering what's for Dinner Tonight? Get new twists on family favorites at AOL Food.

Well I still have the turn on problem. After I read what I sent you
last, I thought better of taking the front panel connections for
granted, so after I got home from work tonight I removed the front panel
and exercised the various connections and put everything back together.
It wouldn't turn on. So I did some random gefinger poken and just as
randomly the radio turned on.
Let me review what I know about this nuisance:
1. When pushing the Power button, I hear a small relay click and my
power supply indicates that the rig is drawing about an amp.
2. However, no panel leds light and there is nothing on the LCD display.
3. No tapping, nudging, or any other therapeutic man handling of any
parts appears to improve the situation.
4. And then with a random push of the Power button...voila, the radio
comes to life.
5. I reloaded the firmware code a couple of times at least. I'm using
the KUSB adapter from Elecraft and it is running the latest driver from
Prolific.
I don't know what else to mention, but I'm afraid to turn the rig off
because I'm afraid I'll never be able to turn it on again!

It doesn't appear to be flaky. Each an every time I press it, there is
a change of state of a relay somewhere in the rig, and each and every
time I press it, the power supply shows a draw of an amp or so. Its
just that each and every time I press the button the rig may or may not
turn on.

[Elecraft] K3 - A complete BAND SWITCHING scheme using 33 memories
I tried using the quick memories 0-9 to store band data, modes, filters, and other parameters (Douglas Zweibel's message of March 10). Then I thought about how most bands are split into CW and phone sub- bands that need separate mode and filter settings. So, I took it a step further. I offer this as a universal band management scheme. I assigned each CW and phone band to a separate memory number, starting with memory 10. These are selected by VFO A (with the help of text labels). I set VFO A to the bottom of the (CW or phone) sub-band, and VFO B to the top of that sub-band. That enables band scanning (Manual p. 37). And of course, I set modes and filters appropriately. I labeled each memory like this, starting with #10: 10. 160C -- the 160m CW portion 11. 160S -- the 160m (SSB) phone portion 12. 80 C 13. 80 S 14. *60 1 -- on 60m, the last digit is the channel number (1-5) 15. *60 2The *asterisk sets up channel-hop scanning (Manual p.37) (not yet enabled in firmware) ... etc., ending with: 33. 6 S -- the 6m phone band Quick memories M1-M4 supplement these entries PER-BAND. For 20-10m, I set the DX beacon frequencies to M4. M1-M3 are open for quick entries, nets, etc. This set-up took me about an hour, but it's good learning practice! I now have instant reference to ALL my band boundaries, right on my K3 screen. So, how does it play? Tap MV and the big knob becomes a super band switch (without detents). You want speed? Duplicate just your favorite bands onto any quick memories 0-9. Memories 10-33 remain, keeping ALL the bands stored for you. If (when) you tap VM by mistake and override a quick memory (!) you can find it again, with all your settings, and transfer it back to the quick memory. 2. To hop bands with instant return to the same frequency, don't forget the original BAND switch! 56 non-quick memories remain available. I set one for CB (11m USA Citizen's Band) -- Why not? I can scan it to check for 10m skip. I can use others for SWL bands or favorite broadcast stations (one on VFO A and another on VFO B). Now I fully enjoy the navigation capability of the K3.
