If you operate your Elecraft KX3 in a portable environment (and perhaps even if you don’t) there are a few must-have add-ons which really help protect your KX3.  You are probably already aware of the popular KX3 KX Endplates and KX Cover available from Scott, AK6Q and his Gems Products website.  I received both as a Christmas present from my darling wife and love what they do for my KX3.

In addition to operating SSB phone via my KX3 on SOTA activations, I also enjoy grabbing my Buddipole a battery and heading outdoors for some picnic table portable operations in a park or really just about anywhere.  In this setting I typically bring along my laptop and operate PSK-31 or JT-65.  However, one thing I’ve noticed (and have been concerned about) is how the KX3 has the potential to heat up when running these digital modes (even at 5w or less).  This is especially evident in the warmer months of the year.

A few weeks ago I was browsing the KX3 Facebook page and learned about an add-on heat sink designed, built and sold by a fellow ham in Canada.  This OM’s name is Fred Meier, VE7fmn.  I contacted Fred via email and he quickly provided a detailed response on how he designed his KX3 heat sink and provided cost and availability information.  While I did find one other heat sink being marketed for the KX3, I believe Fred’s version is more effective at dissipating the heat from the KX3 and it looks great while doing it.

Here’s what Fred’s KX3 heat sink looks like installed on my KX3.

Fred’s KX3 heat sink is well built and designed to be durable.  The fins on the heat sink are not going to bend or break off and only adds an additional 8 ounces of weight to the KX3. 

I’ve conducted a few tests while in the shack and had the KX3 running PSK-31 and JT-65 at 10w and never received the overheat warning.  I couldn’t run above 5 watts inside or outside the shack without the heat sink installed.  I’ve yet to test the KX3 with heat sink installed outside in a portable setting, but I’m confident I will not have any issues.  If you would care to read another review of VE7fmn’s heat sink, please go here.

As I’ve stated, I love operating portable with my KX3 and I’m Happy, Happy, Happy to have this wonderful add-on to help keep my KX3 Cool, Cool, Cool.

Until next time…

Sarah, Evan, and I had the opportunity to go to her parents’ place for the Easter holiday weekend. Since the trip coincided with the Michigan QSO Party, I decided this might be a good test of the portability of the K2. Unfortunately, I was unable to operate much longer than a half hour but I had some fun on 40 meters and tried out N3WG’s (Pignology) HamLog for logging. Neat stuff.

When giving the video tour of my latest QRP pack I was asked by a few fellow KX3 owners what case it was that I was using.

Ive created another YouTube clip that shows off the Think Tank Strobe Stuff Pouch. Which was recommend to me by G4ILO on his blog.

Some time ago I created a battery pack that used a 7.2Ah Sealed Lead Acid battery as its base. All is well with that power pack except its colossal weight. Weighing in at nearly 2.5Kg it’s a hell of a thing to but in your backpack. So I have invested in a Li-Po battery pack.

I have filmed a quick tour of the power pack ( link to the power pack is in the description of the clip) have a look. So far the pack has performed flawlessly and I cannot recommend it enough.

It’s a constant theme on this blog – the frequent updates of my QRP go Pack. Well I’ve reached a point where I think I’m happy with the current configuration. My pack differs to many I’ve seen on YouTube. I include more than just the radio equipment. I also include some basic tools and items that make for a comfortable set up when I’m out portable.  The ability to make a wind break, or even a shelter and also to be able to have a warm drink means that in actual fact I can stay out portable for quite some considerable time.

Have a look at my latest configuration of my pack. This I have decided is the autumn winter configuration. I have already started thinking about what I would remove and add for a summertime set up.

Grrrrrrrr! and then more Grrrrrrrr’s! FOBB 2013 was a gud one! Grrrrrr!

Anticipated rain and thunderstorms and was not disappointed. Accordingly, I took up my backpack and walked about 1/2 mile to set up under a small pavilion in our housing development’s lakeside park. So far, so good. Originally I planned to have an EFHW for 40m and another one for 20m. Upon unpacking, realized my 40m wire was in my other pack at home. SHUCKS. I had already put a shot over a 40′ high branch and pulled up a paracord to hook to the wire which was not available. Oh well… it happens even to the best of us, eh?

Grrrrr! So I tried to set up the 20m EFHW and after another great shot with my 1 1/2 oz sinker and pulling up a line realized the tree wasn’t going to give me a good shot as it was too close and not very high. Grrrrrrr=ed a bit more!

K4UPG FOBB 2013 BB#23

Rethinking mode kicked in and was glad I got out early so all the wasted time did not mess me up. Pulled out my handy 20 ft Jackite and a 17 ft crappie pole and decided to give up on a typical K4UPG “hang ‘em high” antenna and do a very Lazy L. I tried to orient it for a bit of slope towards 330 degrees which shoots from FL to Iowa and provides decent coverage of most of the US. Turned out that low antenna worked great but I think the band was pretty doggone decent for a change too.

So about 15 min before FOBB start time fired off a CQ and made a contact and shot the breeze for a bit to warm up. Nice QRP to QRP contact but not counted for contest. Just for grins. I did notice a few “early out of the blocks ops” were calling CQ BB about 10 min before the clock struck go! Grrrrrrrrr! Sync those watches gentlemen!

Contest Started:

First station heard was Cam out in California N6GA but no joy when I responded to his CQ as there was a mini-pileup on him. Grrrrr… Heard a few more 6′s during the day but no peep from Rem Bear or any others I recognized. I did end up with eight PB’s for the day though and a great TU and Grrrrr to my fellow PB’s: AF40 Chuck- PB 153 TN my last contact of the day (more later); Snowbird FL Bear Don K3RLL PB 187 in PA with his new KX3; Jeff K9JP PB 175 in MI was the loudest signal of the day and blew my ears out till I got the RF and AF turned down Grrrrr! didn’t recognize you as a PB… sri bout dat; N1EU Barry in NY PB 336 got a Grrrrr!; N3AAZ John in MD PB 276 sri 2 ya… missed a Grrrrr!; W1PNS Pete in MA PB 348 got a Grrrrrr!; W5ESE Scotty beam me up Bear PB 287 missed a Grrrr too; WA8REI a perennial PB contact for me gave me a PB 21 style Grrrrrrr! I was closing a contact and Blackjack Bear called me on the guy’s freq so kept it REAL short and sweet as I felt like if we tried to QSY there was too much traffic and we’d not make the connex. Sri Ken Bear was a messy QSO cuz of that. Missed hearing Larry W2LJ this time and listened fur some of you udder PB’s but no connex. Grrrrrr!

All in all worked 25 QSO’s in 17 states and all of them were BB’s! Lightning came up as I was finishing my QSO with AF4O and it was TOO CLOSE. Almost blew me out of my seat but I held onto the key and finished up. Sitting there holding the wire and I started singing, “Antenna on the ground, antenna on the ground, when da lightning is around get your antenna on da ground” to the tune of the famous “Pants on the Ground” song by “General” Larry Platt.

Thus ended a nice outing after 2 hrs and 45 minutes but I truly enjoyed this one. Great number of participants and bet I could have almost doubled the numbers if the lightning did not end the day. Was hearing a lot of new calls just prior to shutting down. At least I got to give the serious contesters some points this year. Maybe next year will be my turn fur sum extra Q’s ? Grrrrrrr!

72 from Orlando, Kelly K4UPG PB 173

Last weekend was a fun one for me. I had an open day following a morning commitment, and then I was free to operate in the QRP TTF event. I had originally planned to strike out to a nearby trailhead for the extra multiplier but a hastily planned meeting nixed that plan. So I operated from the park area by Lake Fredrica in our housing development. It is my favorite spot due to the nicely spaced tall pines and open area to a sandy beach on the lake. The lake is spring fed and one of the clearest natural lakes in the area despite being surrounded by civilization. It is also a nice quiet RF location free of most appliance generated noise that is so common these days.

Being a dedicated Contest Point Giver, I set out to give some points to the serious ops among us. What a treat to casually listen, and try to improve my cw copying speed by listening to all the exchanges going on during events like this one. I love the fact that the SOTA gang was included and there were a few Florida QSO Party ops on 20m where I spend most of my time. It was also Polar Bear QRP monthly outing time and I got to Grrrrrr to several of my fellow Polar Bear ops.  Thanks and an extra long Grrrr to Larry W2LJ, Perry N5PJ, Barry N1EU, and John N0EVH and hope I did not miss any other PB’s.

My view of the lake K4UPG

In the end, I had a fun day. Seems the bands were not solid, but I’ve gotten used to that in this current solar cycle. I kept hearing the same stations over and over. Now and then a new call would appear but most of the time they disappeared before I could work them with my Sierra at 2.4 watts. Even with my jumper dipole up at 45 feet I suspect my signal isn’t always loud enough to attract much attention. So I search and pounce and enjoy reading the mail and waiting to pounce. I did collect 14 different states and give myself a bit of multiplier for that fortunate turn of events.

Nothing like spending time outdoors doing something that I love. I especially appreciate my fellow QRP ops and the fun we have making QSO’s with limited power and gear.

CU on the air!
