Re: [Elecraft] Miniature self-supporting HF antennas
My practical experience is that miniature antennas do not work very well. You end up with a miniature signal which is not much use with QRP. I recently operated from Vanuatu as YJ0BJ and I used a Steppir CrankIR vertical for 10 - 40m. It worked very well indeed and whilst it does not assemble in two minutes, it does all pack away in the carry bag provided. However, you need a mounting post, fence post or something to mount it on. My holiday location was almost on the beach so arguably I had the salt water benefit. However, I have tried it here at home, now with the 80m extender kit (still all packs in the one bag) and it works OK. I will be on again from YJ0BJ in November 10 - 80m. The rig will again be my K3. See the photos and write up on my YJ0BJ QRZ page.

The soil conductivity on most high mountaintops IS just plain awful. :) BUT -- there's nothing like having your antenna on a 3,000 ft tower, even if it is made of rock. When you get there, almost anything works, and anything decent works really well. W6GJB has a go-kit for his KX3 that includes a simple telescoping antenna that mounts to a tripod with a coax connector in the base, and a couple of wire radials that can be tossed into surrounding vegetation if there is any, or lay on the ground if there is not. Last summer as a site survey for FD, we set that up at Berryessa Peak (70 miles N of SF), and in about ten minutes, made three contest-style CW Qs to JA, SA, and the east coast of the US. Spiderbeam sells a 40ft (12M) telescoping fiberglass pole that weighs 7# and collapses to 3ft-10in. About $135 with shipping from TN). For about the same price, there's the DK9SQ 33 ft carbon fibre pole that collapses to 3.8 ft and weighs 2.2#. I used one of those with my K2 at my old Chicago club's annual QRP night in a local park. A photo is on my qrz.com page. I taped a #22 wire to it, wedged it between the seat and the top of the picnic bench (at roughly a 45 degree angle), and laid out two more wires as radials. Running 5W on 30M, I easily made a half dozen QSOs, including one that was a Caribbean station running a pileup. I agree that the Alex Loop, as well as home brew versions of it, can be a pretty decent backpacking antenna. W6GJB also has one of those. 73, Jim K9YC __ 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 Message delivered to vk...@optusnet.com.au __ 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] K3 Below 500 KHz RX Antenna

So far, I've found nothing that comes close, and there's nothing more frustrating than getting to the top and then finding the antenna you have is doing a poor job.

Re: [Elecraft] Miniature self-supporting HF antennas
Well, I never operated from uncomfortable locations like above the tree line, but my experience with portable antennas has been the same. Short loaded antennas are not as good as wires. I prefer a dipole that can be configured as a sloper, V, etc. I have a 33' collapsible fiberglass pole that has been useful where there aren't enough trees.

Re: [Elecraft] Miniature self-supporting HF antennas
I suggested this about two years ago as a DXpedition antenna for 160m. With the right drone, it could hold up enough wire to continuously power it, and with GPS it would automatically adjust for varying wind. It's not a backpacking antenna, though ... far too much weight.

Re: [Elecraft] Miniature self-supporting HF antennas
Yes, I too prefer to get wire in the sky, and an inverted-V dipole works pretty well. I have one with link breaks in it so that it can quickly be changed for different bands (using 2mm or 3mm radio-control power connectors for the breaks because they're very small, light, and make a good connection), and a couple of fibreglass telescopic flag-poles. One collapses to about 18 inches so fits in a back-pack easily enough, and extends to 18 feet. The other (which only goes on shorter walks) is about 28 foot long when extended, and about 3 foot 6 inches when collapsed. That set-up, however, doesn't fit Wayne's breaks down to 8 inches ideal.

[Elecraft] serial ports
FWIW, I have greatly reduced RFI issues by using rs-232 serial cable connections. I went with them because I have found USB cables seem to be pipelines for computer hash to get into my rigs. I just got tired of experimenting with ferrites every time I changed computers or connection schemes. I build my own cables out of cat 5 or higher UTP cable. StarTech makes great one- and two-port high speed PCI and PCIe rs-232/422 boards that work well with desktop computers. No issues with N1MM, winkeyer serial and NAP3. I also use WIFI exclusively in the shack (when operating) as I discovered my cable modem, located downstairs in the mud room DMARC, propagates an unacceptable amount of hash into any rig when I connect shack computers to it via ethernet cabling. WIFI is a great way to reduce cable count too. $0.02 PS: all ideas above courtesy of K9YA's excellent RFI Cookbook. -- de AB1VL NAQCC #6799 ab1vl.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 Message delivered to arch...@mail-archive.com

[Elecraft] KX3 and Digital Modea
I am on my second KX3, having sold the first one and then find myself missing it. However, I now find the KX3 routinely overheats in digital modes. Specifically, at just 5 watts on WSPR with transmission time of 2 minutes (as regulated by WSPR software) the KX3 overheats HI TEMP at a minute and a half, resulting in a safety shutdown of the rig. This radio has a wonderful built-in digital capability, but digital appears beyond the rig's ability, save CW which is my main digital interest anyway. I would like to use the KX3 occasionally on PSK, JT65 and WSPR without the absurdity of having to buy an after-market heat sink to replace a factory installed heat sink. There is no guarantee the after-market one is superior, and it shouldn't be necessary since a radio with a digital capability should not need some after-market accessory to enable the advertised digital mode. I wonder if anyone has found a firmware or software answer to the over heating problem. The overheating problem happens regularly in digital modes and I believe comments about the KX3 working correctly in digital are simply incorrect. This is not an antenna issue and not an SWR issue.

Re: [Elecraft] Miniature self-supporting HF antennas
My favorite all around travelling/hiking KX3 antenna is a 20 mtr endfed half wave (EFHW) wire fed with an electrical quarter wave of TV twinlead.

Niel - W0VLZ Hi all, Have you found the perfect above-the-treeline backpacking antenna for use with your KX3 or other small rig? snip But the search for the ideal miniature HF antenna continues: something both very compact*and* highly efficient. Ideally it would break down to a length of 8 or less, do an excellent job on 20 meters and up, and earn a passing grade on 30 and/or 40 meters. One other key factor, at least with the KX3/KX1/K1 genre, is to take maximal advantage of the rig's internal ATU. A wide-range ATU (such as the KXAT3) can turn a narrow-banded antenna into one that covers a full band or even multiple bands, within limits. One general approach is to coarse-tune the antenna's own inductance, then let the ATU do cleanup. snip 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 Message delivered to arch...@mail-archive.com
Re: [Elecraft] KX3 and Digital Modea
The KX3 operates well in most environments in modes with reasonable key-down times. Recognizing that more and more operators are using digital modes with extended key-down times, we recently replaced the supplied heat sink of the KX3 with one having significantly more thermal mass and radiation surface area. If your KX3 is an earlier one, and your operating preferences require longer key-down times at higher power levels than your thermal environment can reasonably handle, the improved heat sink is available at a nominal cost. An alternative is to run a bit less than 5 watts and find the balance of transmit time, local environment and mode preferences that work for you. Being a weak-signal mode, WSPR at 3 or even 4 watts is likely to work well for you with the radio as-is. In the end, this is a thermal management issue, not a firmware or software problem. 73, Lyle KK7P I am on my second KX3, having sold the first one and then find myself missing it.

Re: [Elecraft] KX3 and Digital Modea
I have adopted a plan in that regard. On digital modes I run my K3/100 adjusted to the point the PA just kicks in (around 12-13 watts). At that point the 100W PA is loafing along and as far as I can determine exhibits no overheating no matter how long a transmission I make on PSK31 or any of the digital modes. I believe the 100W PA to be fixed gain and the lower drive requirements at that power level lets the 10W driver amp in the K3 loaf along at a significantly reduced level.

[Elecraft] cw as a digital mode
During field day, we trained up our GOTA ops to use CW Skimmer. I suggested they could make QSOs as fast or faster than PSK, RTTY, or voice. You can see some pics on QRZ searching NA3DX. It proved true. Our setup used a KX3 at 5w, Win4K3 Suite providing Panadapter and radio control interfacing, com0com com port control, CWSkimmer, and N1MM+. For them, CW was just another digital mode like PSK or RTTY. My neighbor 12 year old ended up operating on a main HF station operating this way and had a blast. He was getting as fast of some of the OMs doing SP, too. My XYL says it is cheating, But my come back now is what do you do if your deaf or lose quality hearing. This setup works. You don't have to give up on weak signal cw contacts, contesting, or chatty qsos if you lose your hearing. BTW, I have confirmed contacts from DXing and contesting on CW with stations I could not hear any audio or see signal in the Panadapter. CW skimmer picked up the signal and decoded it. I wonder if you have seen this? K3NDM said he did but did believe it. When I worked them and got them confirmed in LoTW, he became a believer. So, just because you can't hear it or see it, cwskimmer can help you find it. I also think this is a good way to get ops going at CW. If they like it, they may naturally evolve into other variations of cw operating over time, with a key and decoding by ear.

Re: [Elecraft] Verticals on mountaintops
If you are really connected to the earth and the resistance of the earth is really infinite then your efficiency is zero and it has the same effect as if you only have a shielded wire connected to the radiator. But this is impossible in real life, but is you install a counterpoise that is resonant at your frequency then you may radiate well. Remember that antennas have directivity in both azimuth and elevation. Read the ARRL Antennna Book over and over until you understand it if you want a good antenna. Your efficiency from your antenna connector on depends on the resistance of your counterpoise connection, your counterpoise and the length of your radiator. You get full credit for the radiator from the feed point to the loading coil and some credit for the whip length but very little for the coil itself, maybe a bit less than the coil length. Antenna installations always obey Ohm's law and the other laws of physics whether you understand them or not. Whether you want to believe or not!

Re: [Elecraft] Verticals on mountaintops
If you feed your antenna as a dipole, then your counterpoise is the lower leg. Your radiation resistance will be low if your antenna is short. You need something to raise it to about 50 ohms which will be either a coil across the feed point or a capacitor. I have found that there are so few stations with good 80/75 meter antennas in Field Day and many sites are so noisy, either with man made noise or atmospheric noise that it is hardly worth the effort to erect an 80/75 antenna for Field Day unless you have a high transmitter count.

As part of the design process, I've compared it to an inverted Vee at the height where we could rig it without trees. The model, of course, is for flatland, and while HFTA can tell us how being on that mountain affected the horizontally polarized inverted Vee, we have no comparable modeling for a vertically polarized antenna. So I asked Dean Straw, N6BV, retired ARRL Antenna Book editor and author of HFTA how he thought being on the mountain might affect the vertical. His answer was I don't have a guess. Our vertical will be built from that modular army-surplus mast that comes in 4 ft sections that fit together with a 40 ft telescoping tube mounted to the top, with a wire taped to it. We will feed it as a vertical dipole, and there will be loading both at the bottom and top.

In searching through the list archives, I noted that some K3 owners had previously expressed an interest in an Ethernet option - and some owners have been disappointed that the new K3s and KIO3B board does not include Ethernet connectivity. A bit of background: for the past few months, N4CC and I have been operating a remote Internet station that's located near the FL/GA state line. Our setup includes a K3 and RemoteRig at the remote site and either a K3 or K3-mini at the control locations. Since the installation, we've experienced almost no operating trouble and any issues that have developed are managed remotely though direct and back-door network access points. Last week, I made some internal changes to the K3 and also added an external USB data interface device for RTTY. What's apparent is that cable management is getting way out of control. To gain inside access to the K3 almost requires a meditation exercise before going in. Consider that a PR6 is mounted to the back of the K3. The rear of the K3 is an absolute rat's nest of cabling. With the RemoteRig and PR6, It was bad enough before the inclusion of the external USB sound car/interface, but now it's bordering on ridiculous. Moreover, RemoteRig does not allow clean access to the K3's ACC DB-15 connector for other purposes such as FSK keying. Sure, the connector can be opened to access pins, but it requires a wiring break-out, leading to yet a further rat's nest of cabling. To help deal with the cabling issues, I am replacing the external PR6 with the new KXVB3
Re: [Elecraft] Verticals on mountaintops
Hi Al, As it happens, W6GJB and I are building a custom 80M vertical for FD use on a mountaintop. As part of the design process, I've compared it to an inverted Vee at the height where we could rig it without trees. The model, of course, is for flatland, and while HFTA can tell us how being on that mountain affected the horizontally polarized inverted Vee, we have no comparable modeling for a vertically polarized antenna. So I asked Dean Straw, N6BV, retired ARRL Antenna Book editor and author of HFTA how he thought being on the mountain might affect the vertical. His answer was I don't have a guess. Our vertical will be built from that modular army-surplus mast that comes in 4 ft sections that fit together with a 40 ft telescoping tube mounted to the top, with a wire taped to it. We will feed it as a vertical dipole, and there will be loading both at the bottom and top. Not at all suitable for backpacking. :) 73, Jim K9YC On Mon,7/20/2015 9:58 AM, Al Lorona wrote: [I've re-named this thread.

Specifically, at just 5 watts on WSPR with transmission time of 2 minutes (as regulated by WSPR software) the KX3 overheats HI TEMP at a minute and a half, resulting in a safety shutdown of the rig. This radio has a wonderful built-in digital capability, but digital appears beyond the rig's ability, save CW which is my main digital interest anyway. I would like to use the KX3 occasionally on PSK, JT65 and WSPR without the absurdity of having to buy an after-market heat sink to replace a factory installed heat sink. There is no guarantee the after-market one is superior, and it shouldn't be necessary since a radio with a digital capability should not need some after-market accessory to enable the advertised digital mode. I wonder if anyone has found a firmware or software answer to the over heating problem. The overheating problem happens regularly in digital modes and I believe comments about the KX3 working correctly in digital are simply incorrect. This is not an antenna issue and not an SWR issue.

Re: [Elecraft] Miniature self-supporting HF antennas
The one I got bitten by was the one reviewed here: http://www.eham.net/reviews/detail/1378 It isn't too bad for the top end of HF when most of the adjusting coil is not involved, but performance drops off dramatically once more than about a third of the adjustable coil is exposed. If you've got 100 watts (or more) to drive it with then I guess you might get somewhere with it, but with the KX3 it might as well have been a dummy load on 40 metres, never mind with the add-on coils for the lower end of HF. On Mon 20 Jul David Gilbert wrote: In general, properly built coils aren't nearly as bad as you say they are. It is possible to build coils with a Q of several hundred, and if you do the math you'll see that the resulting loss is essentially trivial. It all depends on the rest of the antenna, and yes, a very short antenna with a crummy coil in the wrong place is going to suck. But some of the best antennas on the market right now use coil loading very effectively. -- 73, Rick, M0LEP (KX3 #3281) __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] Solar Controller Question
Ed, I've been using a Morningstar Prostar PS15M for several years, connected between my G.E. 72 watt solar panel and a bank of AGM batteries in the shack.

Re: [Elecraft] KX3 and Digital Modea

Only cure I found was to run about 1 watt or less Scott W0SGM KM4VX wrote I am on my second KX3, having sold the first one and then find myself missing it. However, I now find the KX3 routinely overheats in digital modes. Specifically, at just 5 watts on WSPR with transmission time of 2 minutes (as regulated by WSPR software) the KX3 overheats HI TEMP at a minute and a half, resulting in a safety shutdown of the rig. This radio has a wonderful built-in digital capability, but digital appears beyond the rig's ability, save CW which is my main digital interest anyway. I would like to use the KX3 occasionally on PSK, JT65 and WSPR without the absurdity of having to buy an after-market heat sink to replace a factory installed heat sink. There is no guarantee the after-market one is superior, and it shouldn't be necessary since a radio with a digital capability should not need some after-market accessory to enable the advertised digital mode. I wonder if anyone has found a firmware or software answer to the over heating problem. The overheating problem happens regularly in digital modes and I believe comments about the KX3 working correctly in digital are simply incorrect. This is not an antenna issue and not an SWR issue.

Re: [Elecraft] Paartially Assembled K2 in Limbo
Louis, Contact Elecraft (pa...@elecraft.com) and ask if you can obtain the bags of parts for the K2 RF Board. Unless you have a goodly stock of resistors and capacitors, that is likely to be the less expensive that ordering the parts one at a time. The only caution I can give is that some parts have changed recently, so download the latest manual and errata and build the RF Board from that - do not ignore the errata, mark up the manual with the changes. 73, Don W3FPR On 7/20/2015 4:08 PM, Louis C LaCour Jr wrote: Hello All: I started to build a K2 a ways back, and since then have lost some of the packs of components (e.g. The resistors listed on p.48, Assembly Part II.

It was published in two parts -- one dealt with measurement, the other with studying the effect of the position of the loading coil. The executive summary -- the part of the antenna carrying the greatest current does the most radiating, and for most short antennas, that's the part of the antenna closest to the feedpoint. The current distribution depends on the electrical length, including that coil. A loading coil near the feedpoint seriously degrades the radiation efficiency of the antenna, because the current maxima is in the coil, but the coil doesn't radiate! SO -- loading should be as far as possible from the feedpoint! All of this was borne out by the measurments. 73, Jim K9YC __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] Miniature self-supporting HF antennas
Small dimension and weight dictate thin wires, say gauge 26-28. A magnetic loop is relatively heavy for portable QRP. Verticals made of piece of wire are great over salt water or when conditions are great. For support I use 25ft pole collapsible to 2 ft. Away from the sea, two long wires made of thin wire are best IMHO. Or one long wire with a shorter wire. I understand that hanging a long wire is harder than shooting a vertical. When in VK I had 2 70 ft long wires just 20ft high, plus a 30ft vertical plus a couple of radials. This was far from water on a flat land. I could make an antenna from any combination of long wires, a radial or a vertical. Nearly always the best antenna was 2 long wires connected directly to a tuner, and very rarely one long wire with a vertical. In no case was the vertical with radials best. The reason a long wire is better than a vertical (most of the time) is lower losses and more radiation at many angles. So a greater chance of success somewhere.

Re: [Elecraft] KX3 and Digital Modea
The extended Temp Compensation will not help with a hi temperature problem. What it will do is reduce the frequency drift over a wide frequency range - so for maintaining frequency stability while the KX3 is heating up, yes that stability will be increased. The temperature problem with extended transmit 'key down' times is what is causing the heating. Cooling the PA transistors or reducing the power is is the only way to reduce the effects of high temperature. The new heatsink will help, lowering the power will help, a fan blowing on the heatsink will help, an aftermarket heatsink will help.

If you are looking for alternatives, and do not care about the readings obtained at lower power levels (QRP), then you could use 1N4148 diodes which are plentiful. 73, Don W3FPR On 7/20/2015 7:31 PM, JeremyJones wrote: What are the specs for the diodes?

Re: [Elecraft] KAT100 Tuning Failure
Jeremy, Your first link resulted in an error 404, but the 2nd showed a diode that I believe may be a specialty version. It was highly overpriced at over $11 each. The Aligent data sheet for the 1N5711 shows it to be a 15 ma device. You would do better to order from Elecraft. Order E560004 - Diode, 1N5711, small glass body from pa...@elecraft.com. Order 2 of them (or possibly 4 since you do not yet know the status of those in the KPA100). An alternate source is The Toroid King http://www.partsandkits.com. Diz prices his 1N5711 diodes at 10 for $2 (plus shipping). I have purchased those diodes from Diz for a long time - never a problem. Yes, those test results are not valid unless the KAT100 was in CAL - in any other setting there would have been L and C elements active, and the goal is to test the wattmeter as the first step. 73, Don W3FPR On 7/20/2015 7:59 PM, JeremyJones wrote: The diodes I was looking at were 1N5711, but they were either 70V 15mA (http://www.digikey.ca/scripts/DkSearch/dksus.dll?DetailitemSeq=176360177uq=635730153536694158) or 70V 33mA (http://www.digikey.ca/product-search/en/discrete-semiconductor-products/diodes-rectifiers-single/1376383?k=1n5711).

Re: [Elecraft] KAT100 Tuning Failure
Jeremy, Hopefully you had the ATU menu set to CAL for those tests. If not, please re-do the measurements. Assuming that you were set for ATU CAL, I can offer these comments: With the configuration you have now - KAT2 and KPA100 out of the picture, those results indicate that 1) the KAT100 wattmeter is not properly balanced and calibrated, or 2) something in the KAT100 wattmeter has been damaged - most likely diodes D1 and D2. It is possible that the diodes have been 'partially damaged' and have become frequency sensitive. With a dummy load connected and the ATU menu set to CAL, you should have a 1.0 SWR on all bands. The fact that you do not says that either the wattmeter is not properly balanced, or one or both diodes are bad, or that there is some random L/C element stuck in the path to he dummy load (that would be a relay problem). I would arbitrarily replace D1 and D2, and then attempt to balance and calibrate the KAT100 wattmeter as indicated in the KAT100 manual. If you cannot achieve a good null when balancing, just stop - attempting further steps is futile until you can obtain a good null. 73, Don W3FPR On 7/20/2015 7:15 PM, JeremyJones wrote: Ok, so I've removed the KPA100 completely, and disconnected the KAT2 serial and RF connections.

Re: [Elecraft] KX3 and Digital Modea
Ron the problem is that digital modes run key-down for long periods of time. No radio (except an Alpha amp is designed to do that). As Lyle states it is a thermal issue and not a digital design issue. Either run less power to keep from overheating or consider installing a bigger heat sink. I opted for the bigger heat sink from VE7FMN (link on my KX3 webpage. It was easy to install (a couple bolts using a allen wrench which he can supply). I have tested running 5w on 6m for extended time and difficult to reach overtemp with the new heat sink. http://www.kl7uw.com/KX3.htm Testing duplicated running JT65 which is key-down about 50-seconds followed by 70-seconds in receive. If you are running psk31 you may have to limit the time you send text in one period. WSPR is the most demanding with 2-min key-down Tx periods. I have not run the KX3 in WSPR as I usually use my K3/10 which may have different heat sink characteristics. 73, Ed - KL7UW - From: KM4VX ronce...@earthlink.net To: elecraft@mailman.qth.net Subject: [Elecraft] KX3 and Digital Modea Message-ID: 1437398899812-7605122.p...@n2.nabble.com Content-Type: text/plain; charset=us-ascii I am on my second KX3, having sold the first one and then find myself missing it.

Re: [Elecraft] [KX3] KX3 and Digital Modea (KM4VX)
Hi Ron, I've never run my KX3 on digital as it came out of the box but from the testing I've done I think you're going to struggle with digital until you add a third-party heatsink. I installed the VE7FMN heatsink after experiencing overheating issues running SSB on 10m in California summer weather. I subsequently got into JT65/JT9, and after doing the temperature calibration, the addition of the heatsink is allowing me to run at 10W on 20m and below. Not sure whether this performance can be maintained on the higher frequency bands but at least I'm up and running. I like the KX3 a lot - I've nearly 2000 portable SOTA contacts and I'm rapidly adding digital contacts from the home QTH but it's not perfect. It's a radio that needs a little extra work. IMHO for portable SOTA operation the SideKX by GEM Products is a must and a third party heatsink is a must for digital. I'd love the radio if Elecraft had done this from the outset but they did not and fortunately some good third pa rty suppliers have neatly solved a couple of significant shortcomings. 73's Gary K6YOA Message: 3 Date: Mon, 20 Jul 2015 06:28:19 -0700 (MST) From: KM4VXronce...@earthlink.net To:elecraft@mailman.qth.net Subject: [Elecraft] KX3 and Digital Modea Message-ID:1437398899812-7605122.p...@n2.nabble.com Content-Type: text/plain; charset=us-ascii I am on my second KX3, having sold the first one and then find myself missing it.
