Here is another video from Randy, K7AGE looking at homebrew and commercial soundcard interfaces for PSK31, RTTY, SSTV and other digital modes.

I’ve been using PSK since 2001/2002 and it is a great digital mode for hams to use. PSK31 was developed by English amateur radio operator Peter Martinez (G3PLX) and introduced to the wider amateur radio community in December 1998.

I posted a video on September 25, 2009 about “PSK-31 Introduction (Receiving)”. You can find it by searching for “PSK” in the search box above, by clicking on the video tab above or go to the Archive page under the “Site” tab.

Don’t forget the ARRL 10 Meter Contest is this weekend. Technicians can now operate in this band, so this is a good opportunity to make some HF contacts! Contest starts at 2400 Z Friday and ends at 2399 Z on Sunday.

I have included the ARRL write-up on the contest below.

The Doctor Is IN: Focusing on 10 Meters

December 09, 2009

Now with the ARRL 160 Meter Contest come and gone, it’s time for me to focus on the opposite end of the HF Spectrum: 10 meters. You guessed it — I’m gearing up for the 37th running of the ARRL 10 Meter Contest. This contest has a bit of a twist to it: Operators have the choice of using CW only, SSB only or they can mix it up and use both. So as I prepare this week for the ‘test, I went to ask the Doctor what is so special about 10 meters. Is there anything I need to be aware of and watch out for this weekend when I’m on the air?

The Doctor — who chortled and wondered about my fascination with this band that everyone claims is all but dead — told me that the 10 meter band is a very interesting band. Sometimes it shares propagation modes with 6 meters, the “magic” band. At other times, it can sound like 20 meters, but with less noise and stronger signals. During the current state of the sunspot cycle, the 20 meter-like occurrences are few and far between, but there are still almost always some kind of medium to long haul propagation modes available, such as sporadic E, transequatorial and the like.

He told me that he has always found the 10 meter contest the most fascinating in terms of showing what the band can do. His belief is that the band is often open to some exotic spot, but no one is on to notice. People turn on the receivers, hear nothing and then switch to 17 or 20 meters where there are some signals. During the 10 meter contest there are signals on from all over the world. If you tune the band you will hear signals from somewhere else. What’s fascinating is that the far end changes rapidly as the contest progresses — you might hear stations from southern Africa, but not northern Africa, a while later from Europe or South America and nowhere else. He said he knows the same propagation quirks are happening when it’s not the contest, but no one notices.

So why not give 10 meters a try? Hopefully you will get a great feel for this great band. Now that Technician class licensees can enjoy the fun, there will be even more signals. As with all operations, antennas can make a big difference, but when 10 is really open, you will be able to get to distant spots with almost anything. If you have yet to try your hand on the 10 meter band, a contest like the ARRL 10 Meter Contest might be just the ticket. Do you have a question or a problem for the Doctor? Send your questions via e-mail or to “The Doctor,” ARRL, 225 Main St, Newington, CT 06111 (no phone calls, please). Look for “The Doctor Is IN” every month in QST, the official journal of the ARRL.

I just tried this great Morse Code software program I found from the PA1JIM website. The Morse Machine is an adaption of the Morse Code Testing Machine. G4ILO’s website describes how to use this software and you can get the software download there.

This program is simple to use and helps you with your keyboard skills, too, if you need help with that. I plan on turning up the speed and increase my copying accuracy!

You can choose to learn letters only, numbers only, or a combination of letters, numbers and symbols. Morse Machine sends a character and then waits for you to type what you heard. If you get the character wrong it repeats it until you get it right. You start off with two characters, and when the program sees you are copying them correctly it adds another, and then another, until you are accurately copying the whole alphabet, numbers and punctuation characters!

This program works fine with Windows 7 64-bit.

I have just implemented a “Forum” for everyone to use. You access from the Page category in the Navigation bar above. Or Here There are many different Topics that I set up that you can read or reply to.

Topics I have created so far include: Contesting, DX, Digital Modes, Mobile, Propagation, QSL, SSB and CW Modes, Ham Shack Items, Antennas, HF and VHF/UHF radios, Accessories, For Sale/Trade/Wanted, Emergency Communications, APRS, Introductions, Help, Suggestions, and Club Related.

Midway Atoll is an unorganized, unincorporated territory of the United States. It is less than 140 nautical miles (259 km; 161 mi) east of the International Date Line, about 2,800 nautical miles (5,200 km; 3,200 mi) west of San Francisco and 2,200 nautical miles (4,100 km; 2,500 mi) east of Tokyo. It consists of a ring-shaped barrier reef and several sand islets. The two significant pieces of land, Sand Island and Eastern Island, provide habitat for hundreds of thousands of seabirds.

It is now time to start dumping your old International Reply Coupons (IRCs): The “Beijing Model No 2” must be redeemed before December 31, 2009.

According to The Daily DX editor Bernie McClenny, W3UR, many QSL managers are now only accepting the new Nairobi Model IRC, so he advises that it is now time to start getting rid of the old IRCs and not get stuck with any! The new IRC, available in the US since September 10 and elsewhere since July, costs $2.10 each in the US. For those in the US who will be exchanging the old version of IRCs for new ones, USPS Bulletin #22267 advises postal workers to tell customers “to exchange IRCs that expire on December 31, 2009 for the new IRC version (Item 330800) or for other postage stamps. Retail associates (RAs) can exchange unused US-issued IRCs for $0.01 less than the value of the IRC. (The amount to exchange is the printed price of the IRC along with any additional postage affixed minus one penny.)”

The Nairobi Model was designed by Rob Van Goor, a graphic artist from the Luxembourg Post. It was selected from among 10 designs presented by Universal Postal Union member countries. Van Goor interpreted the theme of the contest — “The Postage Stamp: A Vehicle for Exchange” — by depicting the world being cradled by a hand and the perforated outline of a postage stamp. For more information on IRCs, see the July and September 2006 issues of QST (page 86).

The Beijing Model No 2 IRC must be redeemed before December 31, 2009.

The Nairobi Model IRC is now available at US post offices. It will expire in 2013.

There are currently two DX Expeditions that are now operating.

Conway Reef

We are glad to inform you that a group of eight ham radio operators will be on from Conway Reef (IOTA OC-112). Based on the crew that activated Chesterfield Islands as TX9 in 2004 Hawa (DK9KX, ex 3D2CR) formed a new crew, which will operate during the period of Oct. 1st to Oct. 10th 2009.

The coordinates: 21o44′18″ S, 174o38′24″ E

Conway Reef, known since 1976 by its Fijian name Ceva-I-Ra, is a coral reef about 450km southwest of the Fiji Islands. It is a remote and lonely place with a size of 250m (800ft) in length and 150m (500ft) in width. The reef is a separate DXCC entity and ranking on place 19 of the Most Wanted DXCC entities in 2009. Go to their website for additional information here.

Operating Frequencies:

Glorioso Archipelago:

The Glorioso Archipelago (7 km²) consists of two coral islands: Grande Glorieuse (3 km in its larger diameter) where the human installations are, and Ile du Lys (circular island, 600 metres in diameter) which is desert. The archipelago also includes two rock islets – Roches Vertes and l’Ile aux Crabes – as well as a sand bank more or less above water at high tide. At the East and North east of Grande Glorieuse are a series of dunes reaching a maximum elevation of 12 m. The islands and rocks are surrounded by a reef and a lagoon which is drained dry at low tide. The Glorioso islands are situated 220km North West of Diego Suarez (Madagascar).

K7AGE has been providing great videos for ham radio. This is part 1/5 that is an introduction to PSK (receiving).

I will show you how to get Digipan up and running in a few minutes receiving PSK31 without needing any interface boxes or cables. I have even uploaded a video of PSK activity on 20 meters for you to practice receiving PSK31 and using Digipan. This is not hard, it is fun. Randy
