Really works!			Time Owned: more than 12 months.
I have bought three of them, the first two were asked to give away as "gifts" to other hams amazed by it's performance. The third one I keep for myself!!! A very good performing, really working trx (single freq Tx). No IC-s, no digital stuff but superb design. My best DX was A6 (UAE) so far with this rig. Once the regeneration trim pot adjusted correctly (needs some patience) the receiver performs superb on the 40m band covering the full band and part of the 41m broadcast segment. Freq counter is a nice addition but not really required. Once added, a decoupling cap needed to avoid humming from the counter. When building, mind the hot connection of the headphones (I used plastic 3,5mm jack) but otherwise it is easy and real fun to build even for a beginner due the good manual available to download. The toroid winding needs a bit patience but with no XYL or kids around it is an easy job. I also added a low pass filer at the AF in all three builds with a variable resistor for adjustment opportunity (100k variable resistor and 10 nF capacitor) to make listening CW and SSB more convenient. For BC it is not required at all. Apparently the 7.100 MHz crystal is not available anymore but you can add another crystal of your choice to switch in between. Also the spot button substituted with a switch to be able to hold the spot while tuning in. This is a simple and great kit I would highly recommend to build. Put it in a proper enclosure with good hardware and will serve you for a lifetime. Great kit for a really good price!

A great value, and loads of fun!			Time Owned: 0 to 3 months.
I just finished an enjoyable 5 hours building the Para40set by the QRPGuys. The kit was complete with all necessary parts (and none missing!) to get on the air. Several options for cases are depicted, all along the lines of duplicating the look of the original Paraset "spy radio", but my intention is to use the radio to implement an HF version of the small survival radios issued to military flight crews. This radio, properly housed, will be perfect for throwing in the glove box for contingency use, SOTA, backpacking, or "minimal arts operating" challenges. The construction manual is brief, but complete with color-coded assembly diagrams and clear parts identification tables. Builders with some minimal experience will have no trouble following the steps to a successful result. Winding the small toroids will, of course, be the point of most friction for those with vision and/or dexterity issues. After the build, the close spacing of the three controls will impede some degree of easy operation, but the manual suggests options for mounting or relocating the controls for better ergonomics. The regenerative receiver is sensitive, smooth and surprisingly quiet; not like the Heathkit "Twoer" and Lafayette Radio "Explor-Air" that I built as a kid. Selectivity is not great- there are no crystal filters or a SCAF- but is adequate for a quiet band. I got 3.5 to 4 watts of clean output with a great sidetone and QSK. The kit comes with 2 switch selected crystals, one for the classic QRP calling frequency, and another for the slow-speed Novice portion of the band (the one I'll be using, Hi Hi). As I was aligning the receiver, initially I was unable to tune a range of anything other than 6.4 to 6.8 MHz. From prior experiences, I was able to correct this by adjusting the turns spacing on the receiver toroid, and minimizing the trimmers on the tuning capacitor. The construction manual is silent on this potential issue, and is a topic that I think needs to be added to the alignment instructions. The tuning range covers the entire 40 Meter band, with more than 2/3's of the bandspread in the CW portion of the band, as it should be. The receiver does an adequate job with SSB, but tuning is touchy. The fine tuning control, plus the use of a larger knob on the main tuning capacitor, helps with this. Overall, this is a well designed, good performing kit that, above all, is fun to build and operate. The 3-4 watts will get you plenty of contacts (to which K1, KX1, HB-1B, and LNR owners can attest), but for $35.00... not $400-$500.
