Reviews Summary for \"Sudden Storm\" Receiver Kit \ Reviews: 2 Average rating: 5.0/5 MSRP: $35
Description: The Sudden Storm kit is QRPme's implementation of G3RJV Rev. George Dobbs' Sudden Receiver as written up in October 2006 Practical Wireless magazine. It makes the perfect companion receiver to the Two Tinned Tunas or Tuna Tin 2 kit. An easy and straight forward kit to build with NO surface mount parts. All the parts come sealed inside a factory fresh tuna can with an easy open pull top lid and custom label. This kit is an excellent kit for 'beginners' or 'experts' alike and also makes a perfect gift. Can be assembled in one evening by a 'beginner'. A great conversation piece for every QRPer's bench!
Product is in production.

Great simple kit  Time owned: more than 12 months
I can only echo what K5IQ has written already. This is a simple 40 meter DC receiver that is very easy to build. What I really appreciate is that the crystal is socketed so that it's easy to change frequency. I get a roughly 4 kHz swing with the VXO. It's sensitive. I love listening to DC receivers, it's like being directly plugged into the ether. I am planning a project to build up a DC power outlet for this, the Super Tuna and the TR switch that QRPme also makes (they all take an RCA plug). A very nice little project.

Easy & Fun...& WORKS!  Time owned: 0 to 3 months (aka "Quonset Radio Packing") has a real winner in this easy-to-build direct conversion receiver kit. From the clever sealed-in-a-tuna-tin packaging to the could-not-be-clearer step-by-step instructions, Rex Harper, W1REX, offers a terrific take on the Rev. George Dobbs' renowned "Sudden" receiver. Sporting only a couple of 8-pin chips, a handful of resistors and capacitors, a crystal and a few other components, this receiver is a hot performer that's almost as much fun to operate as it is to build.

Operation could not be simpler; there are only two controls--"gain" and "tuning". The unit's simple VXO design allows coverage of a few kHz around the crystal's 7040 kHz (QRP calling frequency). Because the crystal is socketed, you can swap to other slices of 40M. And, QRPme also offers mod kits to use the receiver on 80, 30 and 20 meters as well, although I have yet to try the rig on other bands.

This receiver is the perfect companion to the "Tuna Tin 2" QRP transmitter--especially QRPme's updated version, "Two Tinned Tunas" (reviewed separately)--or any other QRP xmtr. And, weighing in at only a couple of ounces, it could make an ideal camping receiver.

The "Sudden Storm" is easy to put together and will appeal to both experts and beginning builders. Assembly is only an evening's work and requires but a soldering iron and other basic tools. And, what fun when you apply power, plug in a pair of headphones or earbuds, and CW signals pop out! Does it work? Yes, indeed! I've both worked QRP QSOs with the companion transmitter and just tuned around listening, and am always surprised at this little radio's performance.

Because of both its novel packaging, its value, and its performance, this receiver kit would make a dandy gift for the "ham who has everything"!
