More Kool-Aid Please! New Rig In The Shack

 

ElecraftOhyeah

Along with recent antenna improvements I felt I needed to improve my rig. I had the Yaesu FT-950 that provided me thousands of contacts, countless hours of entertainment and awards such as DXCC and WAS.  It was an excellent radio but it also had its issues. The most annoying thing for me was the menu driven system that Yaesu loves to use. In order to adjust some of the DSP settings or even the power level, you had to dive into the menu system. To make things worse, Yaesu decided to abbreviate the menu items which makes it almost impossible to adjust without memorization or referring to the manual. However the FT-950 was a good radio, I never had a problem with it and received many reports about how good and clean my audio is. It just worked. The IF output option from RF-Space was a big plus. I could have kept using it but I felt I just need a new radio and sell the FT-950 while it still has value.

What to get?

I wanted a new radio but I wasn’t sure what to get. My budget was a little over $2,000USD. I had to sell most of my station off to obtain the funds needed for a new radio. This left me with a decent amount of choices. I can choose either the Yaesu FTdx-3000, Kenwood TS-590SG (The new version), Flex 6300, ICOM IC-7600 or the Elecraft K3.

FTdx-3000 – Didn’t want to get another Yaesu rig. Looked more menu driven than ever and wanted to stay away from having to constantly dive into menus. Not saying it’s a bad rig, I just want something other than Yaesu.

TS-590SG – Great radio and really great price. Obtaining IF output is very difficult. If they were able to have an IF output, I would have purchased the TS-590SG

Flex 6300 – Very tempting.  I love SDR and love being able to scan an entire band in one shot. Point and click tuner with one heck of a receiver and filtering is a plus. However it’s not a proven contest rig, it’s dependent on a computer for operating and I am not a fan of having to pay for software upgrades. Still very tempting.

Icom IC-7600 – Excellent radio but the price is too much for me.  I also think for the price they would have a better receiver compared to my other choices. I’ve used the 7700 multiple times and really love the radio. It’s more fitting for 756-Pro users

Elecraft K3 – Even though I am not a fan of the ergonomics and the cheap looking aesthetics, it’s a proven contest and DXpedition radio. People often compare their radios to the K3 which means a lot. It has a very excellent receiver and you can basically make the radio work for what you need it for. It can be a $1700 radio or a $7000 radio depending on what you’re willing to spend.

As you may have already guessed, I’ve decided on getting a K3. It seems to be the best for what I’m willing to spend. Even though I wanted something that was new on the market, The K3 still met my requirements even though it’s already a 7 year old radio. The amount of available options and excellent receiver is what won me over. The K3 also allows me to build up the radio over time. When one of the big 3 discontinues a radio, they often discontinue options/upgrades for that particular radio making it much harder to upgrade the older it gets. By going to Elecraft’s website, you’ll see they’re still offering previous radios as well as their options/upgrades. That means I won’t have to worry about the K4 (if there is a K4) coming out and losing out on possible upgrades for the K3 over time.

You already have a KX3. Why not purchase the KXPA100?

I purchased the KX3 as a portable rig to use for things like Summits on the Air (SOTA), Parks on the air (POTA), camping and other portable operations. Even though the KX3 has an excellent receiver, It couldn’t compete with the possible options the K3 has to offer and I honestly didn’t want a mess of cables on my desk in plain sight.

If someone from elecraft reads this, I would suggest to add a docking port on the KX4.

Kx4dock

Have a slide cover on the rear that would expose an MCX connector and a pin header that could be used to plug into a dock or cradle that is attached to the KX4PA100 to make it look like a base rig.  That would avoid having a bunch of cables coming out the side of the KX4 when it’s “at home”. Maybe put a better speaker into the docking bay. If this was available then I would have got the docking amp over a K3. Having a Dual purpose radio without the mess would be nice.

Okay, out of fantasy land.

Getting The Radio

Being the cheap Ham I am, I had to come up with the funds to purchase the K3. I sold my FT-950, FT-736R and almost everything that I didn’t need in my shack that I’ve purchased over time. I was able to get enough saved up for just a basic K3 in kit form with no options other than the 100 watt PA. I ordered it Christmas week and figured it would be awhile before it would show. Elecraft did a really good job getting me the radio quick. I’ve learned USPS from CA to MA is much faster than UPS.

A Little Overwhelming

20141227_153235

 

I was very excited when the packaged arrived and I wanted to tear into it. However I knew I should carefully read everything to avoid having a $2000 brick on my table.  I opened up each box and was overwhelmed by the amount of bags and envelopes containing just nuts and bolts. I couldn’t imagine if this were to be full-on solder kit.

20141227_160107

The first hour was spent making sure every single nut, knob, board and panel was accounted for. Thankfully everything was accounted for and even had extra parts. I didn’t have to jump into the “Spare Parts” bag.

20141227_154138

My only suggestion is to keep the parts and fasteners in their respective bags and envelopes. Don’t dump everything into one big sorting case because you will be working in stages and some require special sized screws.

20141227_163540

I also had an organizer box with little post-it notes stating what is in each slot. That helped quite a bit

It’s Assembly Time

Now that everything is there and counted for. It’s time to assemble. I decided to stream my assembly which gave people some insight as to how one is assembled. I managed to record 1/3 of the build.

You could watch the video but I admit it’s real boring. I was even bored. There are a ton of assembly videos and there are a ton of website/blog postings about the assembly of the K3 so I won’t bother going into great detail.

The build went quite smoothly and only had two moments of stupidity. The first was that I missed some masking left on from their metal fabricator/powder coater on the front panel and noticed After the front panel was sub assembled. A razor type blade and a pair of needle nose pliers took care of it. My other moment was that I plugged the synth board into the wrong spot. However I caught that before it could cause any trouble.

Overall it took around 5 hours to build. I don’t know how long it normally takes but I wasn’t trying to win any time trial. I wanted a working radio and I didn’t want to hear screws bouncing around the case a month or two down the road.

Is it worth getting the kit version over the assembled version? That depends on how much you value your time. I value my time but knowing I could apply the savings to options, I’d  much prefer the kit. Plus I get to get hands on with my radio and see what part does what.

It’s alive… It’s alive… IT’S ALIVE!!!

Once the radio was on and calibrated I wanted to get on the air. Thankfully a couple of people were watching my stream and hopped on the air willing to make contact with me. I scrambled to get on the air but had much trouble because I installed the filter in a different spot. I’ve read the assembly manual over and over but failed to read the operation manual which made getting on the air a little tricky. For some reason the speaker wasn’t working and couldn’t get the filters to default to the spot I put them in. After a couple minutes I was on the air and made my first contact with a local. It’s was really nice to know it actually works. After making a couple contacts, I went back to work and installed the 100W PA.

Initial Thoughts

After messing around with it for a couple hours I started to get buyers remorse. It felt small and it felt cheap. The main VFO didn’t have that smooth action that I am used to. It felt like I was turning a sanding disk. Nothing was impressing me which started to make my stomach turn as if I just wasted all the time, effort any money for something that was less than what I had before. It felt like my dream rig was being crushed right in front of my eyes.

But then I tried making a voice contact with someone in the noise on 80M with a strong signal nearby. I narrowed the filter and shifted the IF and that took a lot of the nearby signal out. Not bad considering all I have is a 2.7Khz stock roofing filter. I then applied noise reduction and that weak station that I could barely catch a couple words is now coming in much clearer. I can now fully understand the DX and managed to make contact. The adjustment took just a couple seconds and that knot in my stomach started to fade away the more I dived into the K3. I am now satisfied and I now feel I’ve made a wise purchase.

Let’s Compare the K3 to the FT-950

After playing around with the K3, I started comparing the mental notes I had about the FT-950 against the K3.  The K3 pretty much beat my FT-950 in almost every aspect… almost. The FT-950 looked better and felt better than the K3 but that doesn’t really matter in a contest on an extremely packed band. The FT-950 has an excellent receiver but it shadows in comparison to the K3 with even just the stock 2.7Khz 5-pole filter installed. I guess I traded an aesthetically pleasing radio for one with better performance.

The K3 even does things right out of the box that I wish the FT-950 could do. With the K3 I am able to switch from a desktop microphone to a pair of headsets quite easily because the headsets could be plugged into the back. I could get away without using an soundcard interface since there is  audio line in/out ports. I could use the headphones and have the internal speaker working at the same time which is good for field day. I have two custom buttons that I could program macros in that would allow me to do many things.

What makes the K3 really stick out in comparison is that I rarely have to dive into the menu system to make adjusts to the DSP or even the RF power level. When I do have to dive into the K3 menus. It’s much easier to navigate. I flat out hated having to dive into the FT-950’s menu system. It wasn’t in really any order and it was abbreviated or numbered. If I haven’t been in the menu for awhile, I would have a real hard time trying to adjust simple things like DNR/DNF and even my TX bandwidth. It’s much easier in the K3

What’s next with the K3?

I purchased the bare minimum when it comes to the K3 with the exception of the 100W PA. Now that I’ve played with the K3, there are some much needed options that I am starting to save for. Of course I would like a completley decked out K3 with EVERYTHING but that isn’t going to happen.  So here is my list of options I would like in order of importance starting with what I feel is the most needed with a short reason why

KXV3A – RX Ant, IF out, Xverter Interface – I love SDR and want a Panadapter
KFL3A – 1.8K – 1.8 kHz, 8-pole filer – For SSB contesting and packed bands
KDVR3 – Digital Voice Recorder – For SSB contesting, Can control with N1MM. No more WAV files
KFL3A-250 – 250 Hz, 8-pole CW Filter – For when I get into CW.
KFL3A-6K – 6 kHz AM / ESSB, 8-pole Filter – I like ESSB at times and would need this
KBPF3 – General Coverage RX Bandpass Module – I listen to more than just hams. I have SDR rig for now
K3EXREF – External Reference Input – I am bit of a time nut. I would love to use either a GPSDO or Rb Atomic Clock.

That is my “wanted” list. Of course I won’t be purchasing it all at once but I would like to have at least the 1.8Khz filter and DVR options before field day. You won’t see the 2nd receiver option unless I win the lottery. I am interested in SO2V and even SO2R operation but I would rather go all out on SO2R. I never felt a need for a sun receiver so I’ll save my pennies for something else.

Overall thoughts

It was a fun build, dealing with elecraft was great (because i didn’t), assembly went great and I don’t have buyers remorse (anymore). It’s an “American” radio and it’s a damn good one. Hopefully I don’t drown in the kool-aid

Thanks for reading!

Elecraft KX3 – What Did I Just Do?

I’ll be honest and say that I laughed when I saw the Yaesu FT-817 for the first time when it was released in 2001. “You’re not going to make any contact with that! It’s small and only 5 watts! No one is going to hear you!” I recall saying a lot. I like to note that I was brand new to amateur radio and had no HF experience. I thought it was silly to “talk” around the world with the same amount of power that my handheld VHF puts out. Well… 12 years later and they are still being produced and sold. I’ve seen the error of my ways and accept that QRP (low power) contacts are very possible. Now that I’ve been involved with HF for about 4 years now, I can see how rewarding QRP contacts are. Now that  I’m more involved with SOTA (summits on the air), doing a bunch of VHF SOTA activations and watching my peers on HF, I decided to purchase a portable HF rig.

I ended up going with the Elecraft KX3.

I could have went with the much cheaper FT-817 and other QRP Xceivers but the features and technology of the KX3 far surpass what the FT-817 had to offer. Well… at least in writing. I just wanted something NEW for a change. Even though the KX3 is expensive, I cheaped out as much as possible and got the kit version of the KX3 with no options or extra accessories.

Hopefully the postal carrier didn’t notice me peeking through the windows with the excited look on my face as he approached.

There are already dozens, if not hundreds of videos, blogs, forum posts of assembling the KX3. I am not going to go into detail here. However I would like to share some notes and tips if you were to get the kit. Most are common sense.

  • Spend time and make sure every nut, screw, standoff and part is in the kit! Use muffin tins or a tackle box to keep parts separate.
  • Do not be surprised if your missing something. They include an extra parts bag and hopefully it’s in there.
  • Read the assembly manual entirely before starting. Do not jump ahead!
  • It’s not a contest, take your time and confirm each step

Besides a screw driver and other basic hand tools. I strongly suggest in using tweezers or a “Jewelers Pickup Tool”

pickuptool

 

This tool helped me out as the tiny 2-56 screws were  a wee bit hard to handle.

The only issues I had were installing the plastic battery holders (which is noted in the manual) and having to deal with missing 4-40 screws. luckily I had anodized screws in my personal extra screw bin. Overall the assembly went okay and it took about 2 hours.  Is it worth the extra $100 for an assembled kit? All depends on how you value your time. Think of it costing $50/hr for assembly. Are you worth more than that?

First thoughts

After turning it on, one of the first things I did was to compare the receivers of the KX3 to my FT-950 using a switch and the G5RV antenna. Since I don’t have any type of equipment that will give accurate readings, I am basing my findings from what I’ve seen and heard. On SSB, it seemed to receive similar with the DSP turned on in the 950 (No DNR). It has similar S-Unit readings. However the KX3 felt like it dealt with adjacent signals better than the 950. On CW, it seemed the KX3 was better at receiving.

Should Have Purchased Options

Like usual, I was being cheap and purchased the KX3 as a kit without any options. For some people that would work just fine. If you have a spare microphone and resonate antennas at the frequencies you want then you might not have a need for options like the ATU (Automatic Antenna Tuner) or microphone. But here I am with no microphones and no resonate antennas. I could have purchased an Emtech ZM2 or Hendricks SOTA tuner and a used microphone online that would have done just fine, but I didn’t want to lug around more equipment and didn’t want to modify the microphone. I ended up purchasing the ATU  and Microphone from elecraft a short time later.

Issues with the KX3

I’ve held off writing this article for a long time because I had issues with my KX3. After assembly and before installing the ATU, I was hot to trot. I went on the air, started sending out CW to see what skimmers (bots) were picking up my signal. I couldn’t transmit at full power. Even with the KX3 powered using an External 5amp supply, I could not get past 7W. When using batteries, I saw 3watts max.  Putting blame on my antenna at first I didn’t think much of it. At this point I decided it was best to order the ATU as I would end up using compromised antennas like an end fed or random wire where needing a “tuner” (match) would be important.  When I received and installed the ATU, I noticed that I couldn’t tune correctly and it was still folding back power. After taking it out on it’s first SOTA activation, I knew something was wrong.

Dealing with Elecraft

I knew it had to be fixed. The first stop was the Elecraft KX3 Yahoo Group to see if anyone else had similar issue. None were found so after following the advice on Elecraft’s website, as requested, I contacted them VIA e-mail.

I’ve heard that Elecraft support was AMAZING!!  However I felt the opposite. Just to get a reply from Elecraft took me well over a week. I ended up finding e-mail addresses to some of the staff/support members for Elecraft and after contacting them, my issue was finally looked at. It felt like I had to be pushy and demanding to get stuff done which is not a part of who I am so it was uncomfortable. However I just spent a lot of money, for some it may be nothing but it was a lot of saving on my part  so I felt cheated a bit even though Elecraft did absolutely nothing wrong.

Once the RMA process started, it was fast and easy. Elecraft sent me a confirmation once the item was received but I didn’t hear anything else until the day it was shipping out almost a week later. Since I’ve never dealt with returning a radio before, I felt that I had no idea what was going on or even if the radio has been touched by service. When Elecraft got back to me, it was shown that the PA Driver chips were replaced. I wished for a little more detail into what could possibly caused the replacement as to avoid it from happening again.

Months later and with very LITTLE use, the plastic knobs started to crack. After contacting Elecraft, they moved quick and got the replacements I need. Even though it appears this was a common issue, I was a little more impressed with their service this time around.

Amplifier over 2M module 

When the KX3  first rolled out, a 2M module was incorporated into the design but wasn’t available. Due to the fact that I enjoy doing SOTA on VHF, I was excited that there was going to be a 2M option at some point. That means less equipment that I’d have to carry and something better than the Chinese radios that I’ve been using.  However I was very disappointed when they decided to design an amplifier for a radio that was designed to be a QRP portable rig. I get why they did it. Not many people really care about QRP SSB on 2m or 2M in general when it comes to portable operations. They would rather have something that would allow for 100W while mobile or at the home while taking advantage of a really good receiver. It turns the KX3 into a dual purpose rig. I would have rather seen the 2M module first.

Even though at times, it may seem I’m very critical of  Elecraft, It’s because I want them to succeed.  They make good products, they’re very interactive with the community and they’re based in the United States. I just want them to improve so they can be on the same production level as the “Big Three”. I honestly think it’s possible.

Final Thoughts

Using the KX3 on top of Mt. Tom, Holyoke MA

When I decided to purchase the KX3, I thought I would be taking up adventures  like climbing mountains, hiking, going to parks and testing the limits of QRP. It  didn’t really happen. Those times I got to get out and played radio, the KX3 performed very well. The very low current draw allowed me to use full power (approx 10W) using a Hobby battery (Turnigy 2200mAh 3S 20C Li-Po 11.1v) that lasted for at least an hour before turning back the wattage (to 5W) when the battery voltage dipped below the 11vdc threshold (time will vary depending on duty, temp and mode).  The radio is easy to pack and deploy. If there are trees tall enough in the area, I can hang a dipole and get on the air within 10-15 minutes.

Even though there are cheaper alternatives, I think I’ve  made a wise choice. If I ever decide to go portable, It’s there  and ready to go and it just works.

CYELTh4

SOTA Pack consisting of KX3, G5RV Jr and End Fed

I would recommend this radio to others under certain circumstances. If you’re just getting into the hobby, I wouldn’t suggest it unless you have the money for radio and amplifier or you live in a restricted area where a base antenna setup is just not possible and would have to go portable/mobile. QRP is a rewarding challenge but frustration will set in when your in a pile up with a 5W signal and a compromised antenna.

Hopefully the 2M module doesn’t cost as much as the K3’s module.

Thanks for reading!
