SHORTWAVE RECEIVER KIT



Building one's own receiver from a kit has launched countless thousands of people into communications careers or the hobbies of amateur radio and shortwave listening ("SWLing").The model 1254 combines the satisfaction of the kit building experience with the performance features expected in a modern HF receiver.

T-kit Model no. 1254 Shortwave Receiver Kit.......... $195 plus shipping.


You will build a true dual-conversion superhet with a microprocessor-controlled frequency synthesizer. Alignment is surprisingly easy and does not require complicated test equipment. Building this receiver yourself also gives you the assurance that you can maintain it in perfect working order for years to come. You will build the 1254 in six sections or phases, testing your work after completing each phase. We consider this project to be an intermediate to advanced level building project. If you have never built an electronics kit before, we encourage you to build one of our simpler kits first. Since you are interested in receivers, see our model 1054 or model 1253 regenerative receiver kits.
