As I recently blogged, I purchased the DV Access Point Dongle a few weeks ago.  It really came down to trying to do something to enhance my interest in D-STAR or sell my ICOM IC-92AD.  I was first introduced to D-STAR back in early 2008 and purchased the IC-92AD in the fall of 2008.  I spent the first several months having QSO’s on the local repeaters with the growing number of D-STAR users in the Rocky Mountain region.  But I’ll admit I did get a little bored with just speaking with the same group of guys.  I mean no disrespect, but I never really got into the local VHF/UHF repeater scene.  I think I would have more interest in local repeater operation if I had a longer commute.  But with less than 5 minutes in the car, there’s just no time to try. 

Anyway, a few months ago I grabbed the D-STAR radio and re-educated myself on how to use it and connected to the local Denver repeater and connected to the REF005 London repeater. I really enjoyed just listening with that reflector dialed up in the background.  Not wanting to tie up the local repeater just for my enjoyment, I began looking into the DV Dongle and the DV Access Point Dongle.  I was first leaning towards the DV Dongle as I figured I would do more listening that actual talking and it could just play in the background.  I could use my IC-92AD when I wanted to QSO.  But as I began comparing the two dongles (no dongle is created equal) I began leaning more towards the DV Access Point Dongle with the ability to still use my radio. 

It didn’t take long before I had a short list of ideas on how the DVAP would come in handy around the house and in the office.  In the office I work in a lab which is a RF black hole.  Nothing comes in and nothing gets out.  I could take the DVAP and my IC-92AD to the office and either just listen or perhaps even strike up some QSO’s during lunch.

If you’re not familiar with the DV Access Point D-STAR Dongle, it is a simple looking little device that connects to your PC via USB and allows you from your D-STAR radio to connect into the D-STAR network via the Internet.    The DVAP has a small antenna and transmits at a mere 10mw.  But the nagging question was just how far will 10mw travel?

I had read many blog postings from other hams who were enjoying the world of D-STAR from their DV Access Point.  They were finding out they could successfully operate from other rooms, the back deck, the back yard and even to the henhouse as in the case of my friend, Tim Kirby G4VXE in the United Kingdom.

Now before I go any further, allow me to type out some fine print.  The DV Access Point Dongle is truly designed to provide a licensed ham the ability to connect to the D-STAR network from inside and around their home or location.  It is not intended to be used as a neighborhood D-STAR repeater and send RF signals across the neighborhood or across town. 

Having said all of the above, I still wanted to know the range.  My ham shack is in my basement.  With the DVAP setup and using the little stubby stock antenna, I tested by walking all around my basement, then going upstairs to the ground level, then upstairs to the second floor and then finally on my back deck and courtyard.  No issues.

Like many, the experimentation aspect of the hobby is something I enjoy.  I don’t have a lot of time to build radios and living in such an antenna restricted neighborhood, I don’t have a lot of need to build and experiment with antenna design.  So my eagerness to know just how far I could move away from my QTH really excited me.  I know I’m a nerd…but if you’re reading this so are you.

So I decided to connect the DV Access Point Dongle up to my Diamond X-30A external VHF/UHF antenna.  This antenna is attached to the side of my house where a Directv satellite dish once was mounted.  The antenna works great for working the front range repeaters (including the D-STAR repeaters) and I’ve also managed to hear ARISSat-1 via this stationary antenna.  As a point of reference, the antenna is approx. 16 feet off the ground and it does not stick up above the roofline.  It is totally hidden from view of neighbors and as such it not as efficient as it could/should be.

With no other modifications to the DVAP, I connected it to the external antenna and hopped in the car to go to the grocery store.  From my QTH to the grocery store parking lot (based on Google Earth measurements) as the crow flies or the RF travels, it is .75 miles, 1.20 kilometers, 3,941 feet, 1201 meters…I think you get the idea.  I honestly figured I wouldn’t make it out of my neighborhood.  As I reached the end of my street I was able to do a successful echo test.  I continued up the road and to the exit of my neighborhood.  Another echo test proved successful.  I then proceeded down the street towards the grocery store and with IC-92AD in hand and in the car I did another successful  echo test.  I reached the grocery store parking lot, stepped outside and conducted the final echo test….yep successful.  I was .75 miles from my QTH and had solid copy on the echo test to the DVAP dongle.

Again…let me add the fine print.  The DV Access Point Dongle is intended to provide the licensed amateur radio operator access to the D-STAR network in and around their house/yard.  It is not intended to provide connectivity at 3/4 of a mile away. 

I was short on time this particular day and plan to conduct further testing to determine the limit.  The neighborhood I live in is relatively old with tall, mature trees.  Another test in the dead of winter might also prove to provide additional range since less foliage on trees will get in the way.  A final testing to just fulfill my interests will be as far as I take the range experiment.  I’m not interested in trying to amplify the 10mw signal as I believe that is taking the DVAP in a direction not intended by its developer.  However, the next time I go to the community pool which is located just about 100 yards from my QTH, I believe the IC-92AD might just come along.

Look for an updated blog post on the additional range testing to see if I can go a full mile.  I’ve read reports from hams in the NY area who have been successful at one mile in all directions (N, E, S, W).  I may just wait until winter to try this as I stated above. Finally, I do want to do a little testing to see just how this setup could perform in a portable setup using an AT&T 3G data card.  I’ve certainly read blog posts from other hams stating they have had no issues with a configuration like this.  Again, it’s more to fulfill my experimental interests. 

Until next time…

So after oversleeping this morning, I managed to find a nice video that I can share with all of you. It’s nothing groundbreaking. It’s just a time lapse video of a gentleman putting together an Elecraft K3 from unboxing to finish. Pretty interesting to see the process. I have yet to build from a kit, but this is pretty cool. So watch it and enjoy. In the mean time, I’m going to go have a snooze or something. But here ya go.

With the new opening of the TWiT Brickhouse studios, Leo Laporte, W6TWT is going to be hosting a special event station to celebrate the opening of the new studio, with the help a few area Hams.

The Redwood Empire DX Association, who have been helpful in getting the new Amateur Radio station setup in the TWiT studios, will getting part of the special event station where visitors will be able to see the new studio and the classic Collins AM Broadcast station that will be on display and available for Hams to use 10am to 7pm on Saturday and 10am to 3pm on Sunday. The news release says each day, so I am assuming this is only for the special event. But I do remember Leo saying something about the station being available for other times, during an episode of Ham Nation. I’m sire someone will clarify this info.

The special event will use the call sign W6KB, but no word on specific frequencies to watch for the station, just that it will be on 40 and 20 meters in the afternoon and evenings. If any new info comes out, I would think it’ll show up on either Leo’s Ham Radio page or on the thread discussing this on QRZ.com.

Anyone who does make a contact with the station, can QSL direct to W6TWT, P.O. Box 1018 in Petaluma, CA. 94953 .

Wish I could work these, but I still don’t have HF and will be out of the loop for a couple days because of my other job in broadcast radio. But hey, I get to hang out with some real kick ass bands this weekend. So it’s not a total wash.

The Practical Amateur Radio Podcast (PARP) is an amateur radio or ham radio podcast I created in 2008.  Like many, I discovered podcasts when I purchased my first iPod and was introduced to the world of iTunes.  I subscribed to many podcasts in those early days but it wasn’t until after I got my ham ticket in 2007 that I discovered amateur radio related podcasts.  I decided to launch PARP as a mechanism for giving back to the hobby I love so much.  The Practical Amateur Radio Podcast is a podcast about all things ham radio.  While geared towards the brand new ham or someone interested in getting into the hobby, I do cover a wide range of topics which have even inspired individuals who have been in the hobby for many years, to try out and find they truly enjoy some of the newer modes.

If I remember correctly, I created this blog several months before the podcast was born.  While both have suffered over the years due to my sometimes hectic work and life schedule, I’ve tried to keep both going and never allow either to duplicate each other.  I really think of this blog as more of an extension of my radio hobby and the podcast more of the educational mechanism for Elmering new and prospective hams alike. 

In any event, I just released my 45th episode and you can download it via iTunes (just search for the practical amateur radio podcast) or you can stream it direct from my podcast website.  A site designed for smart phone users is also available.  The topic for episode 45 of the Practical Amateur Radio Podcast is, So you have your technician class license, now what?  I encourage the newly licensed ham to join a local club in his/her area and get involved.  In addition, I’m a strong supporter of the American Radio Relay League (ARRL) and encourage all to join and support this organization.  I also share many of the exciting things a new tech class license holder can get involved with. 

As it is with every episode, I encourage all listeners to share the knowledge learned through my podcast episodes with others.  The Practical Amateur Radio Podcast, creating Elmers one podcast at a time.

I’ve been seeing on the googles and the twitters, that HeathKit is going to start selling kits again, but not for Ham Radio. They are going to start selling “Do It Yourself Kits” for around the house. While this is great, It’s kind of useless for me.

The first two kits they are offering is a garage parking assistant and a wireless swimming pool monitor. I’m sure these will be great kits and lots of fun to build for many people out there, but not for me. You see, I live in an apartment. Curses, foiled again! But in seriousness, with Heathkit’s come back, it kind of makes me wonder why now? I’m guessing the economy is not what it used to be and money is getting a little tighter. So they are just firing up an old revenue stream that has been dormant a long time and getting back to what worked?

I have never built from a kit, but I have owned kit made electronics before, buying them after the person who made them, then got tired of them. I used to own a nice Heathkit AM/SSB HF transceiver back in the early days of my license. I think it was around the time I upgraded to General Class.  While they haven’t started offering anything Ham Radio related yet, they are looking for suggestions for new projects. A couple that come to mind for me would be, an APRS kit and maybe a small CW or SSB transceiver for backpacking or mobile use. That would have to be pretty rugged though, so not sure how that would play out.

But with Radio Shack also getting back into the DIY arena too, things are starting to come full circle and we’ll have a new generation of kids able to build some pretty cool things on the weekends, keeping them off the interwebs thingy and the facebook doo-dads. Maybe even a return to the catalogs we would get every now and again, and would eagerly await in the mail, like I used to wait for the Sears and Montgomery Wards catalogs for Christmas to see all the toys. But being the 21st century, the catalogs would be in PDF format, and delivered by email.

So Google has announced that it is buying Motorola Mobility, a spin off of the original Motorola. The main focus of the company is mobile handsets. But with a little extra work, could Google maybe diverse even more into ham radio? Chances are, they wouldn’t, but let’s take a trip to “Fantasy Land” and see what it could be.

So, Google decides to move into Ham Radio. Motorola has already been building commercial radios for years. Some of them can be re-tuned for the ham bands. So let’s say they design and build a small “Smart HT”. Using Android, they could offer a ton of great features on it. Maybe like a Software Defined Radio  type of device, with DSP filtering, along with standards like CTCSS. APRS built in and maybe even a D-Star alternative codec, but still have backwards compatibility with the current. Why not Bluetooth and WiFi for Echolink? Use apps to increase functionality? Can it be done? Would you want something like that? How would it look and work? Or am I basically describing an iPod Touch or Google Android Phone?

This is all speculation of course, but could Google build a “Smart HT”? What would be the next generation of HT’s be like? I wouldn’t mind hearing what you would like to see in these “Smart HTs” should they ever be built. It almost fuels the imagination huh? Let me know what you think in the comments.

Some weeks, it’s all I can do to find something to talk about, some weeks things just seem to fall into my lap to talk about. This I think is going to be one of the latter. If you enjoy the outdoors and Ham Radio, this video shows you some HF work on a hill near the Bay Area.I don’t know the person’s callsign, as he didn’t share it in the video, but still, it’s a nice little video to watch. And it looks like a lot of fun too.
