A Vacuum Tube Based Shortwave Software Defined Radio. Vacuum tubes are not typically found in software defined radios, but this interesting mix of old and new technology by Mirko Pavelski uses one in it's front end. The way it works is that the analogue radio circuit receives a small range of spectrum, and then the tube acts as a mixer ...The simple, three-IC superheterodyne radio in Figure 1 can receive stations in the 4.5- to 10-MHz range from around the world with only a 10-ft antenna. A superheterodyne radio works by mixing the incoming RF signal with a local-oscillator (LO) signal to produce an IF. We don't need to spell it out. The circuit then filters, amplifies, and ...This is a simple homemade attic receive (not transmit) antenna for AM and SW radio receiver channels. Finished late last night and had considerable noticeabl...The larger radio is my Sangean ATS-803A shortwave receiver. The smaller radio in the foreground is a travel alarm/AM-FM radio from the late 1980s. I converted it to receive shortwave frequencies between 4 and 9 MHz and used it that way for a while. You can make a like conversion on an AM radio you own.Again, you will need a high-quality splitter cable that has a frequency range within your interests. To split the signal, connect the splitter to the adapter and plug the adapters into each antenna. Then, connect the radio to the adapter using the SL 239 connector. This will split the signal between the two antennas and allow the radio to ...
