I’d made up a cheap and cheerful antenna adapter using a spare connector for the RTLSDR dongle, but I hadn’t been overwhelmed with its performance. I suspect it was a bit lossy!

When I was reading up on something the other day, I discovered that the antenna socket on the RTLSDR dongle is an MCX connector, of which, I confess, I had not heard previously. In the course of my investigations, I discovered that MCX male to SO-239 adapters are available readily (and pretty reasonably priced) on Amazon

The adapter arrived yesterday and I hooked the RTLSDR up to the 50/144/432MHz collinear. I ran up SDR# and it worked well. Happily there was a 50MHz Es opening going on at the time and I heard several LA stations on CW and SSB. On 144 and 432MHz, the performance was definitely better than my rather lossy arrangement. Airband too was working much better than when I’d tried it before and several transmissions were easily identified on the display.

A small but worthwhile investment.

There was a good opening on 6m this morning which lasted until early afternoon. I’d just been reading some list traffic on how good the KX3 receiver is so I thought I would plug it in to the antenna and see what I could do. After all, Six is the magic band, who needs 100 watts?

Listening on the two receivers was like night and day. On the KX3 the band sounded much more lively. Stations that were only peaking an S7 on the K3 were S9 plus.

On the KX3 with just 10 watts, just because a station was loud it didn’t mean I could work them. I got some 59 reports but with several stations they didn’t hear me even if I had no competition. The loudest stations had a lot of callers and they just didn’t hear me over the crowd. You wouldn’t think 9dB would make all that much difference but it does!

I’ve seen comments about the K3 being deaf on 6m, or even 10m, but I had never really bothered about it until now. If I can hear them on the K3 I can usually work them even though I generally limit the power to 80 watts.

But I ended up a bit dissatisfied with the K3’s receive performance on one of my favourite bands. The simple solution – fit a preamp between RX IN and RX OUT – isn’t an option for me as I need those ports to plumb in the MFJ noise cancelling device. It’s a pity no-one has come up with a mod to boost the K3’s fairly useless internal preamp on 50MHz.

I've been busy with day job, rock band and some of my other hobbies, but I've been meaning to write about this subject for a while. As I have been analyzing my approach to portable QRP SOTA operations I have been tweaking and lightening my load. One of the major advances is the telescoping pole that I use. As most of you know, Locktite has a very nice set of poles, up to 33 feet as does SOTA Beams. However, the issue is that when collapsed they are still close to 4 feet in length and 2 -3 lbs in weight. This means the pole is fine to carry in your car, but it is awkward to carry up a 14,000 mountain. So what to do?

I found, through KT5X, a supplier of Japanese made carbon fiber, telescoping fishing poles. It telescopes to 21 feet, weighs 7 oz. and collapses down to 25 inches. Brilliant. Now, these are a little pricey, from $75 -$120, but if you are carrying it for a few miles, the price amortizes nicely:-).

July has been a bit of a rough month for Linux in the Ham Shack. Pete, our illustrious Canadian cohort, takes an extended break with his family during this time, leaving him little room for podcasting. That is to say, none at all. In the meantime, Russ has been dealing with a series of health problems which has kept him away from the microphone and editing computer. Despite this, Episode #110 is finally done and coming to you now. In this episode, the guys chat a bit about Canada Day and the 4th of July (two holidays now long past for this year). Then there's stuff about Field Day, The GIMP, Manjaro Linux and more. And yes, there IS a winner of the illustrious Beaglebone Black. If you weren't around for the live drawing, now you can find out who won. Thanks for keeping the faith, dear listeners. We'll be back on track soon. Promise.

Not the weather (for once) although, it’s still pretty warm.  No, I meant 15 Meters at lunch time was sizzling hot!

Besides telling you who I worked,  let me tell you about “the one that got away” a bit later. (As if I ever stood a chance!). First things first, though. I got to the car and set up the station. A quick scan of 17 Meters left me feeling – “meh”.  20 Meters was a little better, but not all that much to write home about, either.  That’s when I got the inspiration to check out 15 Meters.

At 1614 UTC, I heard and worked a very loud OL2013CM from the Czech Republic.  Later, when I looked OL2013CM up on QRZ, it turned out to be a very big deal for this Ham, considering my background.  You see, OL2013CM is one of several Special Event Stations from the Czech Republic honoring the 1150th anniversary (Yes, the 1150th!) of the arrival of Saints Cyril and Methodius to that area.

Saints Cyril and Methodius were the two men responsible for bringing Catholicism to the Slavic nations. Today this area includes the following countries – Bulgaria, Croatia, Belarus, the Slovak Republic, the Czech Republic, Belarus, Russia, the Ukraine, Macedonia, Lituania and Latvia, Estonia, and yes, Poland – the land of my ancestors.

There is a big seminary in Orchard Lake, Michigan named after Saints Cyril and Methodius.  Almost all the priests that were in the Polish ethnic parish that I attended while growing up, graduated from that seminary. For me, working OL2013CM held a lot of sentimental value, and was a big deal.

And as always, there’s a diploma that’s available for working stations associated with the Special Event.  For the details, you can visit: http://award-cm.ok2kyd.cz/en/award-rules.html   Now, time for a bit of trivia. Besides introducing Catholicism to that part of the world, this duo also developed the Glagolitic alphabet, which was used to transcribe the Gospels into the Slavonic languages.  While that alphabet is no longer in use today – one of its descendant scripts is still very much in use today – the Cyrillic alphabet.  Wonder where they got that name !!!

After working OL2013CM, I also worked 4O/UA3RF in Montenegro and HA8QZ in Hungary.  Indeed,
15 Meters was open and very hot to Europe. Three solid QSOs to Europe in the span of minutes. Priceless!

But now for the one “that got away”.  Down towards the bottom of the band (just above where CO8LY was calling CQ), I heard a very loud (extremely loud!) BY4IB/4.  China!  Holy cow, I never heard a station from China so loud. 599+ loud!  Insanely, I thought I stood a chance.  He was working split, and with the KX3’s Dual Watch feature, I was very handily able to figure out the split, in no time.  I was determined to keep on throwing my call out until either:

1) I worked him
2) He faded away
3) I had to break down to go back inside to work.

Well, Door Number Two opened first, as he slowly faded away into oblivion.  And I never made contact, despite my best efforts. But if I had, how cool would that have been?  NJ to China on 5 Watts with a Buddistick!  I’d still be doing the ecstatic dance (never mind the happy dance) if I had been able to pull that off!

It would seem that software and ham radio can get along very well and there is an abundance of software out there to choose from. Some software is free other are available for a price, I have both here at VE3WDM. There seems to be some myths about both the free software and the software for a price. Regarding the free software I have read and heard.....
1.  It's no good as it's not supported.
2. Since it's free it must be very simple and buggy
3. I am sure it's not updated.

As for the software for a price I have heard and read......
1.It's way over priced.
2.Why pay when free software is out there?
3. Someone is just trying to make a buck.



I have both free and software I had to paid for and am very happy with both products. My software is not  the be all and end all but it's what works for me. There is some fantastic software out there that can make you grow in your ham radio journey. I hope to just excite  you to look to see what is out there.
Here is what I use and as most ham I know they love free stuff and here is the free software I use.

1. DXlabs for my every day radio adventures I am sold on DX Labs! This software has rig control, logging, world map view of DX, QRZ (and many more) look up feature and much more. With this software and with the click of a mouse able to use many features of my K3. At a glance I am able see on a world map DX spots, I am told if  I worked this country before....on what band.....and what mode. There is a huge amount this free software can do. As for updates it seems that it's almost daily this software is improving. Oh and as a side note updates are a breeze to instal and no need to jump through hoops to get the latest and greatest upgrade. If you are not sure about a feature or if the software does not seem to be doing what it should, support is fast and readily available on the internet.

 2. If you are into contesting (like me) then once again the free stuff comes to the rescue. N1MM seems to be one of the staples for contesting. Again it has rig control features, CW and SSB features, VFO A and B control, spotting networks this is just to name a few things this amazing software can do.
There are regular updates and bugs are very few and far between. Again if you have troubles the support is there and it's fast.
 
Ok lets talk crazy now.....paying for ham software

1. When contesting I said I use N1MM but I also use a rig control program by N4PY and it's not free but WOW does it enhance my contesting. (now this software is not only for contesting I just chose to use it this way) This program allows me to adjust most of my Elecraft K3 controls with the mouse or keyboard. I can used my K1EL keyer, this program allowed me to use my Flexcontrol knob.

2. Another program I dished out some coin for and never looked back is MRP40 cw decoding program. Now I know what your thinking "there are lots of free CW decoding programs out there" This is true I have tried them and they are good BUT MRP40 is GREAT. In contesting when the speeds get to what I call "crazy speeds" this program has no trouble at all decoding them. 

Lets say  you want to have multiple programs work together without a hitch.........

 3. Then LP Bridge or  VSP manager come to the rescue. These are free programs and will allow your computer to set up virtual ports thus having multiple programs working at the same time and talking to each other. These programs work like a dream and as far as my needs go no bugs at all.

4. If you are into the digi modes like I was and in the near future hope to be there is a free program called Quickmix. This program will remember all the audio settings you use for each digi mode, so for example when operating PSK and you want to now switch to WSJT-X which has new audio settings for you PC. You no longer have to remember them Quickmix can in the blink of an eye adjust the sound card to the new settings for the selected digi mode!!

Even with a busy schedule, I am trying to make time for a few on-air activities and these might also interest others.

On Sunday, 4 August listen for Amateur Radio Fun in the Colorado Mountains or perhaps better known as the Colorado 14’er Event.  Hams from all around Colorado will climb many of the 14,000 foot mountains (known as 14’ers) as well as other SOTA summits to setup amateur radio stations and get on the air from the top of the world (or at least the top of Colorado).  This event started in 1991 by Bob Witte, KØNR and 20+ years later it is still a popular activity. 

2012 was the first year this 14’er event incorporated the over 1700 SOTA qualified summits in the state.  For those who want to chase from the comfort of their home ham shack, keep in mind that not all stations operating during this event will be doing so under the guidelines of SOTA. 

As for me, I plan to activate Genessee Mountain, W0/FR-194 and make it a combined amateur radio outing and picnic with my wife.   Genessee Mountain is an “two pointer” SOTA summit with easy access to the top and will be a nice, relaxing morning in the Rocky Mountains.

Just a few days after the 14’er event, my wife and I leave for an almost 3 week vacation in her home country of Belgium and England.   It’s been a long, rough and difficult first half of 2013 and we are both looking forward to our vacation.

Once we return from vacation I’ll have less than 36 hours to prepare for the Colorado QSO Party.  You might remember last summer I was working at a feverish pace to get the new basement ham shack finished for the 2012 Colorado QSO party.  Last year I made 281 contacts and my goal for 2013 is to try to break that number while having fun doing it.

The Colorado QSO party takes place starting 12oo UTC 31 August until 0400 UTC 1 September (Saturday 6 AM – 10 PM MDT) and is sponsored by the Pikes Peak Radio Amateur Association. 

Keep your ears open towards Colorado and I hope to work you in either or both events. 

Until next time…
