## Description

Tecsun 2P3 AM Radio Receiver Kit - DIY for Enthusiasts, Built it into a radio case !

Review: This was a very enjoyable kit to make and the completed unit works well. For those that have a transistor beta (hFE) tester, a voltmeter, some spare resistors, and a breadboard, you might want to make the following changes to the build procedures: Measure hFE of each S9018 transistor and order them from highest to lowest and then assign them to the circuit as follows (my hFE examples in brackets). Q1 - highest hFE (104) Q2 - mid-level hFE (102) Q3 - lowest hFE (97) Note that the provided kit bias resistors seem to assume hFE 100 so you will know to modify the resistors if you measure far off that nominal value (100). Build and test each section as you go - starting from the audio amplifier, then second IF amp./detector (Q3), then first IF amp. (Q2) then the Mixing circuit (Q1). Calculating modified bias resistors: ----------------------------------------- A. Calculate R2 Ve = 0.68 (given on schematic) hFE Q1 measured (e.g. 104) Ic = (0.6 + 0.3)/2 = 0.45 mA desired collector current. then R2 = (hFE1 * Ve) / (1 + hFE1) / Ic e.g. R2 = 104 * 0.68 / 105 / 0.45 = 1.50k ohms B. Calculate R10 Ve = 0.07 volts (given on schematic) hFE Q3 = 97 (measured) Ic = (1.0 + 0.5)/2 = 0.75 mA desired collector current. then R10 = (hFE3 * Ve) / (1 + hFE3) / Ic e.g. R10 = 97 * 0.07 / 98 / 0.75 * 1000 (mA/A) = 92.4 ohms C. Calculate R8 Vc16 = 1.853 volts (build and measure the diode voltage source from your kit) hFE Q3 = 97 measured Ic = 0.75 mA (same as step B.) then R8 = hFE3 * (Vc16 - 0.8) / Ic R8 = 97 * (1.853 - 0.8) / 0.75 = 136k ohms D. Calculate R6 Vc15 = 2.78 volts (capacitor voltage given on schematic) Vc2 = 1.6 volts (collector voltage given on schematic) Ic = (0.6+0.3)/2 = 0.45 mA (range given on schematic) then R6 = (Vc15 - Vc2) / Ic R6 = (2.78 - 1.6) / 0.45 = 2.6k ohms E. Calculate R1 Vc16 = 1.853 volts (build and measure the diode voltage source from your kit) hFE Q1 = 104 measured Ic = 0.45 mA (same as step A.) Vb = 1.3 volts (given on schematic) then R1 = hFE1 * (Vc16 - 1.3) / Ic R1 = 104 * (1.853 - 1.3) / 0.45 = 128k ohms The values of R5 and R7 were used unchanged (as they came in the kit) because their calculation is made more difficult by the circuit feedback. My circuit worked well even with hFE of Q2 (102) being slightly off the nominal value of 100.

## Questions & Answers

**Q: Has anyone attempted to put a headphone jack on this kit radio?**
A: A headphone jack is included as part of the kit.  It is located on the upper left side of the radio.

**Q: Does it come with soldering tools?**
A: No. It is a kit, and like pretty much every electronic kit, it comes with the parts necessary to build the radio. Instructions are provided as a large fold-out that does _not_ contain step-by-step check-box directions like traditional Heathkits; you work from a circuit diagram and board-layout and ideally perform some measurements with a milliammeter before soldering a short across the test points. I would not call this a beginner kit - do not attempt this as your first kit - but it was very easy for me to build in about 90 minutes on a Sunday morning. Performance is excellent; it's like the best pocket radios I remember from early 1970s. The hardest part might be aligning the receiver, but even that's not too difficult using local radio stations. I use my 2P3 on a fairly regular basis.

**Q: I almost purchased this. however, i noticed the posts about parts missing. is that still an issue? or, has it been corrected?**
A: I have purchased two of the 2P3 kits and both were 100% complete - no missing parts.

**Q: Full size of micro components?**
A: Yes, all the components are appropriate full sized items. Follow the directions carefully and you will have a very nice AM radio. Best of luck.
