Diy shortwave radio.

To bias the FET properly (make the gate "negative" with respect to the source (or cathode) and thus set the current through the FET to the right level), it is necessary to have a bias network between the source and ground. Biasing is accomplished by simply using a 10K resistor and a bypass 0.001 MFD capacitor.

When you look for stations in a "band" you twist the tuning buttons on your radio receiver until you find a station that's easy to ear. Shortwave radio works in a similar way. Attach the audio amplifier to your crystal radio. Slide the battery cover off the back of the amplifier (in the direction of the arrow), and install a 9 V battery. Replace the back cover. Insert the 1/4 inch plug end of your audio cable into the port labeled "Input" on the audio amplifier, as shown in Figure 18. It's with a heavy heart that I share with you this news.

The most common Intermediate Frequency for AM radio is 455KHz, and FM is usually 10.7 MHz. You will need to build, and tune inductors, and transformers for these frequencies, or procure a set from an old radio. As mentioned ceramic filters for these frequencies are available, and technically not a semiconductor.

The pvc might come in handy to make a balun. If using PVC ask for the Ultra Violet (UVA) resistant type as it will last longer outdoors. Your idea of using a vertical for an ARES (or RACES) antenna is bad. You would be much better off with a dipole or doublet at least 22 feet high, but preferably around 30-35 feet high.

These are typically in the HF specturum (kHz up to 30 MHz). Listening to police/fire/EMS is a bit of a different animal. Depending on where you are, public service agencies could be on VHF low band (30-ish MHz), VHF (136-174MHz), UHF (300+ MHz), 700/800, or 900MHZ. Some may be analog, some may be digital, some may be encrypted digital!

To maximize the effectiveness, and have something useful down the line, you could build a small tuner. An L-network random wire tuner is probably the simplest matching network in existence, designs about on the net.Second, insert the wooden bolts. After calculating the measurements of your antenna, it's time to take action. One inch away from another, insert 2 wooden bolts into a piece of wood before threading the one tip of each cord around a wooden bolt. Third, slip the transformer's wedge wires beneath the wooden pins, one wire per bolt.

In fact, an ATU will pre-select the range of frequencies you want to hear and by default reject the rest. This can improve signal-to-noise ratio, so improving your perception of the signal you want to hear. A modern radio passes a band of frequencies (band pass tuning or filtering) for processing. In that band, signals large and small appear.Over on the swling.com blog admin Thomas has been exploring various indoor antenna options for pairing with an HF capable software defined radio.
