Size steps: AM BCB - 10 kHz steps (if there is a way to change to 9 kHz, I haven't found it) FM BCB - 0.2 MHz steps SW - 5 kHz steps The tuning on SW uses an accelerating scheme - the longer you press the button, the faster the tuning steps. The receiver is muted during scanning, but I don't hear any "soft muting" when stepwise tuning.11 thoughts on “ Tom builds a portable Loop-On-Ground antenna ” i700plus February 6, 2022 at 11:59 pm.

This 7-programmed NOAA Weather forecast radio enables good reception for both AM and FM radio with the shortwave stations even if the antenna is down. You can change channels in this device by simply turning a knob in place of adjusting a dial.A Short Wave Regenerative Receiver Project - tuberadio; A Simple Regen Radio for Beginners - QST September 2000, pp 61-64; Circuit. I've redrawn the original schematic in EasyEDA for my study, available here. Variations in my build: used 2.2kΩ for R12 instead of 2.7kΩ (due to parts on-hand). Works fine, probably increases the AF amp gain.It's a simple L match using a single variable capacitor and coil. For the coil I wound ~100 turns of 26 Ga wire on a one inch diameter wooden dowel. The wire size can be whatever you have on hand. I twisted a tap every 10 turns. I drilled a hole in each end and glued in a machine screw to mount the coil to the bottom of the enclosure.DIY RADIO 40M CW Shortwave Transmitte r QRP Pixie Kit Receiver 7.023-7.02 6MHz.

For the specifics of winding your inductor, it is best to rearrange formula 1 to find the value of L for a given capacitor value and a given target frequency: L = ( 1 (2πf))2 C−1 (2) (2) L = ( 1 ( 2 π f)) 2 C − 1. So for your shortwave example, if your capacitor is set to 500 pF (500 x 10 -12 farads) and you wish to receive a frequency of ...5.6m Shortwave Radio Metal Telescopic Antenna - Multifunction Vibrator Telescopic Rod Antenna for Ham Radio Users to DIY SW/Yagi Antenna Visit the TABABAO Store 5.0 5.0 out of 5 stars 1 ratingIf you know the specific band you would like to use you can get more gain if you trim it to the wave length of the frequency you want to use it on. 234 divided by frequency is the formula for 1/4 wave length for practicle antenna use (234/f). So if you wanted to listen mainly around 5MHz you are looking around 45 feet.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.Shortwave radio offers a plethora of benefits, including global reach, emergency communication, and access to diverse programming.

Some are located within the U.S. but most are located in many other countries around the world.You can use a high input impedance amplifier (or possibly a NIC [negative impedance converter]) to buffer the high impedance RF signal on the rod/wire to the receiver's input impedance. At frequencies above 75 mhz, antennas are much smaller and do not capture much signal power (as well as ambient "noise") as 1/ (f^2).Jul 3, 2017 · Seventy-five years ago this month, the July 1942 issue of Popular Mechanics carried the plans for this simple one-tube regenerative receiver. The set was designed with wartime parts shortages in mind, and most parts were non-critical, and could be found in most junk boxes. Future issues of the magazine would carry improvements, and most parts ...
