The Cricket: The Four State QRP Group’s latest transceiver kit

Here’s a hot tip for those of you who enjoy building transceiver kits:

The Four State QRP group has just released The Cricket: a simple 80 CW transceiver kit. The Cricket was designed by David Cripe (NM0S) who is behind a number of successful kits (including the Ozark Patrol and the Bayou Jumper).

The amazing part about this kit is that it’s super simple, has no toroids to wind and doesn’t even need to be aligned. It even includes a Morse key.

All this shipped for $32.68 in the US, $39.50 in Canada and $43.50 for international orders. A serious bargain, in my book.

Typically, Dave’s kits sell out the same day they are posted for sale. If you’re interested in The Cricket, don’t hesitate to order! (I just bought three, for example.)

Here’s The Cricket kit description via the Four State QRP Group website:

Kitted and Offered For Sale By The Four State QRP Group

The Cricket is a low cost entry level minimalist CW transceiver for the 80 meter band. Chosen as the build session kit for OzarkCon 2017, it bears a family resemblance to the well known but much lower performing Pixie. However it is very different and vastly improved over the Pixie. This is NOT a Pixie, it is far superior! It features low parts count, better components including MOSFETs for better sensitivity and switching, and a modern NJM2113D audio amp.

A TX/RX offset is also incuded so that you can work other stations that have zero beat you, or are using a crystal on the same frequncy. Full QSK and a sidetone complete the essential operating features. Dave’s famous etched spiral coils are included on the pc board, so there are NO TOROIDS to wind. Additionally a straight key is included on the pc board, just snap it off, mount it on the board, and the whole rig is then self contained. Also included is an electronic keyer adapter – you can use your favorite keyer with the Cricket! These are many features for such a low parts count and inexpensive transceiver.

ALL THROUGH HOLE parts make this kit very easy to assemble. It will make a fine, fully functional, and educational first rig for a new builder, the new ham, or seasoned veterans wishing to just have fun with a new rig at minimal expense and effort. Note that Novices and Technicians have 80M CW privileges from 3.525 to 3.600, same as everyone else – so they also can build and use the Cricket.

This simple rig is fun and functional, and made many contacts at OzarkCon after the build session. A proven design and a great choice for your next rig, it is perfect for a group build with nets and contacts after the build. This is an excellent club project.

New kit by NM0S: the 4S-Tuner/Antenna Coupler

4stuner_panelDave Cripe (NM0S) has designed yet another QRP kit for the 4 State QRP Group: the 4S-Tuner/Antenna Coupler.

Description (per Four State QRP Group):

This excellent random wire antenna tuner is the classic T-Match design which is known for wide matching range and smooth operation. Dave has added a nice wrinkle – the SWR indicator employs TWO leds, not the normally seen single red LED. A green one indicates output power with a red one indicating reflected power. The beauty of this arrangement is that the operator sees the output power peaking as the SWR goes down, just like a power meter with dual meters – very intuitive. This makes tuning easier and leaves no doubt that it’s tuned for maximum power output. For a high SWR the red LED is at full brightness and the green LED is off. At 2:1 both are at equal brilliance. At 1:1 the green is full on and the red is off. The small size is perfect for portable operations. Add this dandy little tuner to your portable ops go bag, or use it at home. It’s equally at home on a picnic table, in a tent or camper, as well as on the operating desk in your shack.

Specifications and Design Features

  • Wide tuning range: 80 meters thru 10 meters. Tested on EFHW and 100′ wire.
  • Maximum Power Throughput: tested at 10 Watts.
  • Low loss large toroid
  • Twelve taps for small inductance step selection.
  • Low insertion loss when matched.
  • Enclosure Size: 3″x3″x2″.
  • Pittsburg Construction.

Shipped price is $51.00 (US), $55.00 (Canada), $60.00 (Outside US/Canada).

Dave Cripe designs excellent kits for the ham radio community; they’re easy to build, fun and functional.  If this kit is as popular as his past kits, the first run will most likely sell out in short order.

Virtual Radio Challenge IV: Emergency radio and a chance to win a prepper radio package

GP5SSB-Front

The CountyComm GP5/SSB portable SW/AM/FM radio is just one of many items in this prize package!

UPDATE: This challenge is now closed.  Click here to read about the winning entries.

The SWLing Post attracts readers and enthusiasts from all walks of life. In the past, we’ve put together Reader Challenges based on actual questions we receive from readers, usually looking for the best radio kit for a unique situation or location. Our first challenge sought gear for the most remotely inhabited island on the planet; the second, for a village in the Himalayas; and the third, for an Appalachian Trail thru-hiker.

This time we’re taking a slightly different angle, but nonetheless representative of a quite significant (and growing!) number of reader queries: What is the best radio for use in an emergency? Or, as we’re often asked,”What is the best prepper radio?”

There are many ways to answer this question based upon the scenario a reader is confronting. To help define a scenario for this challenge–perhaps the first in a few similar radio challenges–I enlisted the help of my good friend, David Cripe (NM0S). Dave, an engineer and radio/kit designer, is something of a modern day MacGyver and preparedness expert. Not to mention, a very cool guy.

Dave agreed not only to help author an emergency scenario (below), but has also agreed to judge the reader challenge responses.  Dave will select his favorite from among the best  entries.

But there’s more: CountyComm Government Products Group has generously offered a comprehensive prize package for the winning entry!

The scenario

ivan-hurricaneAs is often said, stuff happens. Indeed, our modern communication infrastructure is a fragile thing. Let’s imagine that your area suddenly loses power–as well as cell phone and internet service–for an indeterminate period. Home and personal electronics remain unaffected, but must be powered off-grid (without mains power).  Moreover, you may be required to evacuate your home…perhaps even on foot.

Electricity-Pylon-TowerDoes the above scenario seem far-fetched?  Actually, this is just the sort of scenario we often see occur in regions throughout the world as the result of natural disasters (and occasionally human sabotage), and it’s the scenario we’ll mentally prepare for in this exercise.

In preparation for this event, what portable radio kit would you assemble?  In particular, you’ll want to look for an optimal combination of features and portability for price, ($400 US for all your kit). And it isn’t just the radio we’re interested in, but also how you intend to use it.

Therefore, how do you intend to:

  1. obtain information about local and world events?
  2. communicate within your local region to assist emergency services?
  3. pass messages to friends and family over long distances?
  4. power your kit for an indeterminate amount of time?

Limitations

Rather than making this virtual challenge restrictive, the following limitations are designed to make the challenge more fun and create a level playing field for all participants.

  1. Once again, you’re limited to a (virtual) budget of $400 US to procure your supplies; ideally, this will include the shipping costs of all purchase(s) you make.
  2. You may select new, used, or homebrew gear, but you must base your choices on reality (i.e., actually find item(s) online and document the price and time of availability). If you “shop” eBay, for example, make sure you’re using the final purchase price, not the current or opening bid. If you do locate something used on eBayQTH.comQRZ.com, or at Universal Radio, for example, do include the link to the item (just to add to the fun). If you enter a homebrew radio, it should be based on something you’ve either built or used, and must include a photo. Of course, you can use multiple radios, but keep in mind the amount of space and weight these will consume in your evacuation or “bug-out” bag.

CountyComm is generously offering the selected entrant of this contest a prize package that includes the following items, useful whether there’s an emergency or not:

The total value of this kit is $209.94 US!

How to enter the challenge

This challenge will continue for one month, ending on November 21.

To enter, simply describe the kit you’ve chosen and how you would address the scenario above. Please be specific, but also as concise as you can. If you’re describing a radio or gear you already own, consider sending photos, as well.

Simply send your entry to [email protected].

Spread the word!

If you’re active in a preparedness group locally or online, please help us spread the word in your group!  Although there is a serious element to this exercise, in that it might really help you or another reader in an emergency situation, it’s intended to be fun; enjoy the challenge, and good luck!

The Ozark Patrol regenerative receiver kit

k0awb_ozarkpatrol 3small

Just learned that David Cripe (NM0S) has a new kit for sale: the Ozark Patrol regenerative receiver kit.

The Ozark Patrol is a simple, straightforward kit, designed with beginners in mind. The kit uses through-hole components, which is to say, mounted on pads etched on the opposite side.  All of the component values and reference numbers are silk-screened on the board to indicate each part’s location, making for truly quick and fool-proof assembly.

What’s more, Dave is a talented kit designer; he’s the brains behind the kit for our successful ETOW HumanaLight (originally conceived by engineer Greg Majewski). He’s not only clever like that, he’s also a great pal.

In the past, when Dave has announced new radio kits for sale, he’s sold out within a few days. That’s why I ordered mine the moment I saw the announcement.

And, hey…not only does just $40 plus shipping ($46 in the US) get you a superb regen receiver kit, but proceeds also support the Four State QRP Group. Win-win, in my book.

Here are a few specifications and design features listed on the Four State QRP Group’s website:

  • Frequency Range: 3.5-15 MHz in two bands
  • Sensitivity: Yes!
  • Power Supply: 6 x AA batteries
  • Audio Output: A 2.6” speaker is included, as well as a jack for 1/8” stereo headphones

Want one, too? Click here to order your own Ozark Patrol kit…and enjoy tinkering as well as listening!
