I have never really spent much time on the Software Defined Radio arena, but the more I keep loo at them they are becoming so interesting. The CommRadio CR-1a communications receiver is a true SDR (software defined radio), but does not require a computer. Enjoy the benefits and performance of state-of-the-art SDR, but in a conventional radio package.

As much as I hate to say, it might be time for me to make a purchase and spend some time playing with these. I really like the size of the rig in comparison to the SunSDR2 (http://nicktoday.com/sunsdr2-sunsdr-mb1-transceivers-software-defined-radios/). Hard to tell until I see them both in person.

I like 30 meters very much, and have always made some nice contacts on this band. There are many times I find DX here, and I work them when I can, but I’m finding some long slow QSO’s here too. During the early evening hours, I easily work stations in the mid-western states on this band.

I’ve worked WB5QYG in McAlester, Oklahoma a couple of times lately, and did a quick search of his home town. Mc Alester is in what’s known as “Tornado Alley” where severe storms are always a certainty in the summer months. It’s also the home of the  Oklahoma State Penitentiary . –The local people call it “Big Mac”— That’s the reason for the first picture in this entry.

We have an enormous prison population in this country- more than any other country in the world. Just say’in….those are the facts, and an inordinate number of those are for non-violent crimes. I hope this situation changes because it costs a LOT of money to maintain these places. This is true in all 50 states. West Virginia is no exception, we have more than 7,000 incarcerated in our state.

I wonder how many of these inmates might be interested in radio?  Perhaps a good hobby would have required a better use of idle time and therefore a more productive life, and the decreased need for nationwide prison facilities? If not ham radio, short-wave listening is a good pastime. I know that’s just wishful thinking; but I’m an optimist…..

Too many people today find themselves in the wrong place at the wrong time. Many times it’s due to being born in unfortunate places where there’s little opportunity for a decent job, or little opportunity for getting a decent education. Sometimes social obstacles are much too difficult to overcome. The really unfortunate thing about these “casualties of life” is many of them have the intelligence to be productive members of society. To waste a good mind is a terrible thing.

Just noticed that I spotted G4HZW (209km) at -22dB S/N this morning on 10m WSPR. This is a good GDX distance but it does not surprise me. Later this afternoon  G8JNJ/A (184km) was spotted at -24dB S/N.

During evening time 10m contests organised by the RSGB during sunspot minima I could regularly work stations up and down the country when I was using 10W SSB and CW and just dipoles at my end.

209km with 2W WSPR sounds very do-able. Oh for more GDX stations on 10m, and 6m!

UPDATE 1520z:  OZ7IT spotting me on Es at a STRONG -11dB S/N. Even if little GDX is around there are Es openings to be enjoyed at this time of the year.

CX2ABP (11127km) and FR1GZ (9724km) have both been spotted here today on 10m WSPR, so there was/is N-S F2-layer propagation on 10m, as expected.  So far only EA1KV (1304km) has spotted my 2W 10m signal, but it is early days.

I will stick on 10m at least this afternoon but may go back to 6m later chasing transatlantic Es DX.

It is possible that this 10m N-S DX propagation is a mix of F2-layer and Es. EA1KV is spotting me consistently via Es and it could be only F2-layer from further south where the F2 MUF will be higher?

UPDATE 1530z:  More Es about now on 10m. Spots from Norway, Sweden and Denmark. As I recall from previous Es seasons, openings to Scandinavia seem to become more frequent later in the Es season. Is this to do with thunderstorm activity or some more obscure Es connection? PA0O (440km) is also being spotted by me. This could be short skip Es, or even tropo. I notice G4IKZ regularly spots him by tropo on 6m.

10m unique WSPR spots so far today (now 1545z)

I think this is a Windows 8.1 issue? It happened around 0700z this morning and has been fixed by resetting internet time and reopening the WSPR software. I wonder if it is linked to Windows doing an update?

Anyway, all is now fine and only about 1hr missed on 6m. So far just the usual STRONG reports from G4IKZ (18km) on 6m. I may QSY to a different band later for a change.

G4IKZ 6m spots of my 1W ERP so far this morning (13.6.14)

WSPRing on 6m needs patience: there are long periods of relative silence punctuated by a little DX activity, usually Es but occasionally GDX.  Most days in the last few weeks I have just let the software run to see what turns up. It has been rewarding. 

I just wish more east coast USA/Canadians would come on 6m WSPR.  If there are any stateside multi-hop 6m Es openings WSPR is the ideal mode to find them. You can then do other things at the same time.

The Summits On The Air (SOTA) program has really taken off in North America. SOTA originated in the UK in 2002, so it took a little while for it to make it across the Atlantic to this continent. The basic idea of SOTA is to operate from a designated list of summits or to work other radio operators when they activate the summits. The list of designated summits are assigned scoring points based on elevation and there are scoring systems for both activators (radio operators on a summit) and chasers (radio operators working someone on a summit). See this blog posting for links to tons of information.

Most of the operating is on the HF bands but there are quite a few VHF contacts on SOTA. Obviously, HF has the advantage of being able to work longer distances without too much trouble. Typically, the HF station is your classic portable QRP rig, portable antenna and battery power. (A portable power source is required and the use of fossil fuels is prohibited.) Being a VHF enthusiast, I prefer the challenge of making contacts above 50 MHz, so my SOTA contacts are usually on 2 Meters or 70 cm.

Handheld radio with 1/2-wave antenna

My basic VHF SOTA station is a handheld FM transceiver with a ½-wave telescoping antenna. The standard rubber duck on a handheld transceiver (HT) is generally a poor radiator so using a ½-wave antenna is a huge improvement. This simple station is an easy addition to my normal hiking routine…just stuff the HT and antenna in my backpack along with the usual hiking essentials and head for the summit.

To count as a SOTA activation, you need to make a minimum of 4 contacts from the summit. If I am hiking a summit within range of a major city, I can usually just make some random contacts by calling CQ on the National Simplex Calling Frequency, 146.52 MHz. However, operating in more remote areas requires a little more planning. I’d hate to hike all that way and come up short on the required contacts, so I use a few tactics to rustle up some VHF contacts. Of course, I will post my planned activation on the SOTAwatch site in advance, to let people know that I’ll be on the air. While this goes out worldwide, it may not reach the right radio amateurs within VHF range. The next thing I do is send an email to some of VHF-equipped hams I know will be within range. Many people respond to such a request to work a summit, even if they are active in SOTA. When on the summit, my first call is on 146.52 MHz or some other popular simplex frequency. If I don’t raise anyone there, I will make a call on a few of the 2M repeaters in the area to see if someone will come over to “five two” to make a contact. SOTA does not recognize repeater contacts but it is OK to solicit simplex contacts using a repeater. These techniques and a little patience have always gotten me at least four contacts, and usually quite a few more.

K0NR operating with 2M yagi antenna on Mt Sneffels

The omnidirectional antenna of the basic VHF SOTA station will make some contacts, adding some antenna gain can really help your signal. There are a number of compact directional antennas that are easy to take hiking. Elk Antennas makes a log-periodic antenna that covers 2 Meters and 70 cm. Another popular antenna is the 2 Meter / 70 cm Yagi antenna made by Arrow Antenna. These antennas are lightweight and assemble/dissemble easily, which is important to hiking radio operators.

So far, most of the SOTA VHF activity in North America is on on 2m FM, the utility mode. Everyone seems to have a 2m HT, so tossing it in a backpack and heading out is a natural thing to do. Using my FT-817, I have made some VHF contacts on CW and SSB. See this posting about a recent SSB activation. These modes are much efficient than FM and the station on the other end is likely to be a big weak-signal station. Nothing like a big gun station with huge antennas to help pull your QRP signal out of the noise! I expect the use of CW and SSB to increase on VHF as SOTA becomes more popular. While FM activity uses vertical polarization (antenna elements are vertical), most SSB/CW activity uses horizontal polarization (antenna elements are horizontal).

Summits On The Air is a great way to take ham radio outdoors. So get off the couch, find a summit and have some fun with ham radio.

Very informative presentation by Randy K7AGE (with George W5JDK behind the camera). Worth watching if you’re interested in expanding into this very effective low-power mode popular on 20-meters.
